The Sun has a new nearest asteroid neighbor. A team including IfA astronomer David Tholen has discovered an asteroid with the shortest known orbital period around the Sun - only 113 days. Of all the known objects in our solar system, only the planet Mercury has a shorter orbital period.
A new comet discovered this summer by IfA's Pan-STARRS1 telescope atop Hakeakalā may become bright enough for spectators to see as it moves closer to Earth. IfA astronomer Robert Weryk first spotted the comet on July 26, and after it was reported to the Minor Planet Center, telescopes from around the globe confirmed its cometary nature.
IfA astronomers have identified an unprecedented collection of pulsating giant red stars. Using observations from NASA's Transiting Exoplanet Survey Satellite (TESS), the researchers detected the stars, whose rhythms arise from internal sound waves and provide the opening chords of a symphonic exploration of our galactic neighborhood.
Astronomers have discovered thousands of exoplanets - planets beyond our solar system - but few have been directly imaged, because they are extremely difficult to see with existing telescopes. An IfA graduate student has beaten the odds and discovered a directly imaged exoplanet, and it's the closest one to Earth ever found, at a distance of only 35 light years. Using the COol Companions ON Ultrawide orbiTS (COCONUTS) survey, IfA graduate student Zhoujian Zhang and a team of astronomers, identified a planet about six times the mass of Jupiter.
A new study by IfA astronomers investigates a unique solar magnetic eruption observed during the 2020 total solar eclipse from Argentina. The team found that a Coronal Mass Ejection (CME) had occurred serendipitously during the brief time that the Moon blocked out the Sun over South America, which is analyzed in the new study in the Astrophysical Journal Letters.
Naming asteroids is serious business. In the latest batch of officially named asteroids, five have been given names honoring astronomers at the IfA. These five new designations join a cornucopia of at least 40 asteroids named after current and former IfA astronomers, students, staff and other individuals.
Graduate students at the University of Hawaiʻi at Mānoa Institute for Astronomy (IfA) are raking in recognition for their excellence in research and teaching. Five IfA students earned a wide range of awards in June 2021, many including scholarships and fellowships.
From working to determine if other planets can support life to monitoring the skies for hazardous asteroids and comets, the IfA remains at the forefront of cutting edge space science. Our Pan-STARRS1 telescope on Haleakalā is the world leader in finding larger Near-Earth Objects that could pose a threat to the planet.
Every night, the University of Hawaiʻi Pan-STARRS telescopes on Hakeakalā scan the sky for Near-Earth Objects (NEOs), asteroids or comets that may come close to or even hit Earth in the future. The search is funded by NASA's Near-Earth Object Observations Program. On May 26, astronomers raced against a brief 60-minute window during the lunar eclipse to search for faint NEOs. They pinpointed three to the northwest of the eclipsed Moon. One of them, an asteroid about the size of 1½ football fields, hadn't been seen since 2001.
On May 26, Hawaiʻi enjoyed prime viewing of a total lunar eclipse–when the Earth comes between the Sun and the full Moon. The IfA hosted a livestream of the celestial wonder, which drew more than a thousand viewers from around the world, including Hawaiʻi and the continental U.S.
Current and former astronomers from the IfA have wrapped up a massive collaborative study that set out to determine if most solar systems in the universe are similar to our own. The 30-year Hawaiʻi-based planetary census sought to find where giant planets tend to reside relative to their host stars.
How do stars die, explode and release heavy elements into the universe? These questions are the focus of an international team of scientists led by IfA postdoctoral researcher Chris Ashall. The researchers were recently awarded two programs to conduct detailed observations with NASA's $10 billion James Webb Space Telescope (JWST) flagship mission, set to launch in fall 2021.
The award-winning television show, Xploration Awesome Planet will feature IfA education and outreach specialis, J.D. Armstrong and his students on Saturday, May 15, at 2:30 p.m. on KHON. The Earth science series, which airs on FOX channels nationwide, will showcase Armstrong and three of his students who are part of our HI-STAR mentorship program.
The phrase "out-of-this-world" has taken on a whole new meaning for Ashley Kaya. The Kalani High School senior is interested in searching for signs of an Earth-like planet within Perseus, a constellation that looks like a hunter in the northern sky. Guided by mentors at the IfA, Kaya's ambitious proposal captured the attention of Maunakea Scholars, an innovative program designed to award local students observing time on world-class telescopes.
Fourteen-year-old Anica Ancheta is off to a running start in her pursuit to study the complex cosmos. Guided by the IfA, Ancheta's research on active galactic nuclei (AGN) earned her four exemplary awards at the 2021 Maui County District Science and Engineering Fair.
A team of researchers from the University of Michigan and the UH Institute of Astronomy are suggesting a new way to use quasars to measure the expansion of the universe directly. They propose a method called intensity correlation speckles to measure the difference between the redshift - in which light stretches as it travels through an expanding universe, causing its wavelength to elongate - in two paths of light from the same quasar.
IfA astronomers will play an instrumental role in helping unveil the universe's very first galaxies, more than 13 billion light years away. On Monday, April 19, NASA announced the first suite of science programs for its groundbreaking James Webb Space Telescope (JWST), set to launch in October 2021. The IfA researchers are part of the "COSMOS-Webb" project, which will be the largest guest observer program in JWST's first year of operation.
The incoming director of the IfA, Doug Simons has a set of priorities that he calls the "three pillars" - ramping up research, expanding technology development and retaining IfA's world-class education. Simons' appointment as the leader of one of the world's premier astronomy programs became official at the Board of Regents April 15 meeting.
Veteran Hawaiʻi Island astronomer Doug Simons has been selected as the next director of the IfA, effective September 1, 2021. Simons has worked on Maunakea since 1990 after he earned his PhD from IfA and has served as the Canada-France-Hawaiʻi Telescope executive director since 2012 and was the Gemini Observatory director from 2006-2011.
The University of Hawaiʻi community is mourning the loss of highly respected, deep-sea voyaging canoe Hōkūleʻa captain Chad Kālepa Baybayan, who served as a navigator-in-residence at the ʻImiloa Astronomy Center of Hawaiʻi.
An asteroid that is estimated to be as large as the Golden Gate Bridge will make a close pass by Earth on March 21 when it is about 1.25 million miles (2 million kilometers) away or about five times the distance of the Moon. Astronomers on Maunakea are using the opportunity to improve their tracking of hazardous objects that threaten the planet. The IfA-operated Infrared Telescope Facility (IRTF) on the summit will be used to closely analyze the characteristics of asteroid 2001 FO32 as it passes Earth.
A team, including Dave Tholen from the IfA, have confirmed a planetoid that is almost four times farther from the Sun than Pluto, making it the most distant object ever observed in our solar system. The planetoid, nicknamed "Farfarout," was first detected in 2018, and the team has now collected enough observations to pin down the orbit. The Minor Planet Center has now given it the official designation of 2018 AG37.
The centers of galaxies with actively feeding supermassive black holes are already astounding environments. Now, a team of researchers led by a graduate student from the IfA has found an even more interesting oddball. Feeding black holes typically increase and decrease in brightness similar to the Kilauea volcano, becoming more or less active over time in unpredictable ways. However, the newly discovered black hole is more like Old Faithful geyser at Yellowstone National Park, erupting repeatedly at predictable times.
Almost all of the planets discovered to date (including the solar system planets) are confined to the plane of the Milky Way, unable to glimpse such a sweeping vista of our galaxy. However, astronomers at the IfA, using the W. M. Keck Observatory on Maunakea, have discovered a rocky planet with a different kind of view.
A team of astronomers led by IfA graduate student Travis Berger has shown that an intriguing class of Neptune-sized planets shrinks over billions of years.
Earth is orbited by thousands of artificial satellites, but only one large, natural Moon. Eight years ago, researchers at the IfA predicted that there must be a population of small, natural 'minimoons' that temporarily orbit Earth. On November 22, a team of 23 researchers from 14 academic institutions announced a study on the second minimoon ever discovered, dubbed 2020 CD3.
To trace the volatile elements that form the atmospheres of planets, NASA's Astrobiology Program awarded a five-year, $5-million grant to an interdisciplinary consortium, including researchers at the University of Hawaiʻi. The award will help establish a scientific foundation for detecting the signatures of life on other worlds.
Earth has captured a tiny object from its orbit about the Sun and will keep it as a temporary satellite for a few months before it escapes. But the object is not an asteroid; it's likely an upper stage booster rocket that helped lift NASA's ill-fated Surveyor 2 spacecraft toward the Moon in 1966. Our Pan-STARRS1 telescope atop Haleakalā spotted the object in September 2020.
A collaboration between the LOw Frequency ARray (LOFAR) radio telescope in Europe and two telescopes on the summit of Maunakea, the Gemini Observatory and the NASA InfraRed Telescope Facility (IRTF), has led to the first direct discovery of a cold brown dwarf from its radio emission. In addition to demonstrating a new way for future brown dwarf discoveries, this result is an important step towards applying radio astronomy to the exciting field of exoplanets.
Thousands were mesmerized by a mysterious flurry of lights that appeared to float above Hawaiʻi's evening sky on Saturday, October 24. Photos and videos of the string of lights flooded social media, leaving many to believe the sighting could be anything from a spaceship carrying extra terrestrials to a meteor shower. IfA astronomer Richard Wainscoat believes onlookers witnessed the reentry of a spent rocket booster used to launch Venezualan satellite, Venesat-1, back in 2008.
IfA astronomer David Tholen and his team have revealed critical new findings linked to a large asteroid expected to pass extremely close to Earth. They announced the detection of Yarkovsky acceleration on the near-Earth asteroid Apophis. This acceleration arises from an extremely weak force on an object due to non-uniform thermal radiation. This force is particularly important for the asteroid Apophis, as it affects the probability of an Earth impact in 2068.
Three finalists have been identified for the position of IfA director. The finalists are each scheduled for virtual visits over a three-day period with participants on the islands of Oʻahu, Hawaiʻi and Maui. The visits include: department discussions; meetings with senior administrators, faculty, staff, students and internal and external constituents; and a public presentation. The finalist are:
Laura Ferrarese, Principal Research Officer at Herzberg Astronomy and Astrophysics Research Centre (and former Director, Gemini Observatory)
Kenneth Chambers, Astronomer and Director, Pan STARRS Observatory, IfA
Douglas Simons, Executive Director, Canada-France-Hawaii Telescope
A team of astronomers at the IfA has produced the world's largest three-dimensional astronomical imaging catalog of stars, galaxies and quasars. The team used data from the Pan-STARRS1 (PS1) telescope on Haleakalā. IfA astronomers applied novel computational tools to the catalog, to decipher which of the 3 billion objects are stars, galaxies or quasars. For the galaxies, the software also derived estimates of their distances. The resulting 3D catalog is now available as a high-level science product through the Mikulski Archive for Space Telescopes.
Large reflecting mirrors lie at the heart of the world's most powerful telescopes that observe distant galaxies, stars and planets. A company formed by University of Hawaiʻi at Mānoa Institute for Astronomy (IfA) scientists and students through UH's innovation incubator has demonstrated a new way to shape thin mirror surfaces using high-power lasers.
An innovative new instrument built by a team at the IfA, Caltech and W.M. Keck Observatory provides adaptive optics (AO) correction using objects invisible to the naked eye. The AO system includes an innovative infrared pyramid wavefront sensor that can detect exoplanets and young dwarf stars where planet formation commonly occurs.
What does our own galaxy look like? It's hard to tell because we are inside. A new project, led by IfA astronomer Dan Huber, will change that. Huber and his team are planning to create the largest 3D map ever constructed of stars in the outer regions of the Milky Way, with a new grant from the National Science Foundation (NSF).
For more than three decades, technology development at the IfA has been a prime mover in federally funded astronomy programs, according to a study published in the Journal of Astronomical Telescopes, Instruments, and Systems. The authors tracked the impact of National Science Foundation (NSF) grants for astronomy technology and instrumentation development over the last 30 years.
IfA alumnus Jeff Rich has checked off a big bucket list item. Rich, who earned a PhD in astronomy in 2012 will appear on the season premiere of hit TV game show Jeopardy! on Monday, September 14
Astronomers have known for two decades that the expansion of the universe is accelerating, but the physics of this expansion remains a mystery. Now, a team of researchers at the University of Hawaiʻi at Mānoa have made a novel prediction - the dark energy responsible for this accelerating growth comes from a vast sea of compact objects spread throughout the voids between galaxies. This conclusion is part of a new study published in The Astrophysical Journal.

Scientists expect the inoperative satellite, OGO-1, to break up over the South Pacific, away from inhabited areas at around 10:45 a.m. HST.
University of Hawaiʻi scientists are leading one of the newly announced Key Projects on a worldwide network of telescopes called the Las Cumbres Observatory (LCO) global telescope network. Using thousands of hours of observing time, they will investigate the neighborhoods of young stars where planets are thought to be forming.
On July 20, our Pan-STARRS1 telescope discovered an asteroid 65 feet in diameter that appeared likely to pass close to Earth. Some of the first follow-up images of the approaching asteroid were taken by Hawaiʻi high school students participating in the IfA's HI STAR program, using telescopes from the Las Cumbres Observatory (LCO) global telescope network.
An asteroid discovered on July 20 by the University of Hawaiʻi's Pan-STARRS1 telescope atop Haleakalā will make a close pass of Earth on Monday, July 27. At its closest point, the asteroid will be only about 1.7 times the distance of the Moon.
A team of astronomers at the University of Hawaiʻi was awarded a $1 million grant to upgrade the UH 2.2-meter telescope on Maunakea, giving the mountain's first large telescope a leg up on its larger, newer neighbors, with more nimble, streamlined operations.
For the past decade, an international team of astronomers, led in part by Brent Tully at the University of Hawaiʻi Institute for Astronomy, has been mapping the distribution of galaxies around the Milky Way. They have discovered an immense structure beyond Laniakea, an immense supercluster of galaxies, including our own. Astronomers have dubbed the newly identified structure the South Pole Wall.
June 30th is Asteroid Day, marking the anniversary of the 1908 Tunguska impact which leveled trees and destroyed forests across 770 square miles of Siberia. IfA's Asteroid Terrestrial-impact Last Alert System (ATLAS) is featured in today's United Nations News, as "Earth's last Defence" against asteroids.
The University of Hawaiʻi's 88-inch telescope is celebrating its Golden Anniversary on June 26th. Often called the UH88, the telescope was dedicated on this date in 1970, beginning decades of incredible scientific output, and ushering in an era of unparalleled astronomy from Maunakea. Now, 50 years later, the observatory continues to modernize and pave the way for others.
University of Hawaiʻi at Mānoa astronomers are part of an international team that recently discovered an infant planet around a nearby young star. The discovery was reported today in the international journal Nature. The planet is about the size of Neptune, but, unlike Neptune, it is much closer to its star, taking only eight and a half days to complete one orbit. It is named "AU Mic b" after its host star, AU Microscopii.
While the world has been dealing with the corona-virus pandemic, researchers at the University of Hawaiʻi Institute for Astronomy (IfA) have been hard at work studying the solar corona, the outermost atmosphere of the Sun which expands into interplanetary space. A new study by IfA graduate student Benjamin Boe used total solar eclipse observations to measure the shape of the coronal magnetic field with higher spatial resolution and over a larger area than ever before.
Recently discovered object 2019 LD2, originally believed to be the first cometary “Jupiter Trojan” asteroid by astronomers at the University of Hawaiʻi at Mānoa Institute for Astronomy turns out to be an interloper comet masquerading as a member of the Trojan population.
Asteroids and comets are often thought of as distinct types of small bodies, but astronomers have discovered an increasing number of "crossovers." These objects initially appear to be asteroids, and later develop activity, such as tails, that are typical of comets. The University of Hawaiʻi's Asteroid Terrestrial-impact Last Alert System (ATLAS) is now behind the discovery of the first known Jupiter Trojan asteroid to have sprouted a comet-like tail.
Over the past two decades, astronomers have concluded that most, if not all, galaxies host massive black holes at their centers - and the masses of a black hole and its host galaxy are correlated. But how are the two connected? Now, a student participating in the IfA Research Experiences for Undergraduates (REU) program, may have revealed part of the answer.
New evidence shows the first-ever pictures capturing the birth of a pair of planets orbiting the star PDS 70 are in fact authentic. Astronomers from the IfA were part of a Caltech-led team that used a new infrared pyramid wavefront sensor for adaptive optics (AO) correction at W. M. Keck Observatory on Maunakea. The team applied a new method of taking family photos of the baby planets ("protoplanets") and confirmed their existence.
Ellis Avallone, a second-year graduate student at the IfA has received the 2020 American Astronomical Society (AAS) Solar Physics Division Popular Writing Award. She explained the role of the Sun's rotation rate during the formation of the solar system.

A team of astronomers, including Nader Haghighipour from the Institute for Astronomy at the University of Hawaiʻi at Mānoa, have discovered a third planet in the circumbinary planetary system Kepler-47. This discovery cements the system's title as the most interesting of the binary-star worlds, and marks the first complete and dynamically full planetary system around a binary star.
Astronomers once thought asteroids were boring, wayward space rocks that simply orbit around the Sun. New observations are turning these ideas on their heads, showing that asteroids are anything but dull. Asteroid Gault, discovered in 1998, has begun to slowly disintegrate. The crumbling was first detected on Jan. 5, 2019 by the IfA's ATLAS telescopes on Maunaloa and Haleakalā. Spectacular images of asteroid 6478 Gault from NASA's Hubble Space Telescope show two narrow, comet-like tails of debris streaming from the diminutive 2.5-mile-wide asteroid.

The new object was announced on Monday, December 17, 2018, by the International Astronomical Union's Minor Planet Center and has been given the provisional designation 2018 VG18. The discovery was made by Carnegie Observaties' Scott S. Sheppard, the University of Hawaiiʻs David Tholen, and Northern Arizona University's Chad Trujillo.
A supernova discovered by an international group of astronomers has provided an unprecedented look at the first moments of a violent stellar explosion. The team, led in part by IfA Astronomer Ben Shappee, found a mysterious signature in the light from the explosion's first hour. Follow-up obervations suggest that the traditional original theory for these tupes of supernovae is wrong.
The Star Wars universe turned from science fiction to science fact for a Waipahu High School student, who observed a real-life "Tatooine" using one of the largest, most scientifically-impactful observatories in the world.
The Maunakea Visitor Information Station (VIS) on Hawaiʻi Island will adjust its closing time from 10 p.m. to 5 p.m. beginning Sunday, December 9, for an infrastructure project that will improve visitor safety and to better protect natural, historic and cultural resources. Preparations will begin in December with construction slated to start in January 2019. The project is expected to take about six months.
A team of astronomers, including IfA's David Sanders and former IfA postdoc Mike Koss, have used the W. M. Keck Observatory on Muanakea and the Hubble Space Telescope to complete the most detailed census of supermassive black holes in colliding galaxies. The team's findings support the theory that galaxy mergers explain how some supermassive black holes become so monstrously large.
Astronomers have discovered a new object at the edge of our Solar System. The new extremely distant object far beyond Pluto has an orbit that supports the presence of a larger Planet X. The newly found object, called 2015 TG387, was announced by the International Astronomical Union's Minor Planet Center on Monday, October 1, 2018.

The IfA's Asteroid Terrestrial-impact Last Alert System (ATLAS), a NASA-funded telescope network devoted to detecting space rocks that could crash into Earth, will expand into the Southern Hemisphere, which currently lacks a large-scale asteroid-surveillance effort. The additional observatories will not only spot asteroids that could harm people, but also detect comets, supernovae and other benign celestial objects.
Dr. Benjamin J. (BJ) Fulton, who received his doctorate from the University of Hawaiʻi at Mānoa’s Institute for Astronomy (IfA) in 2017, has been awarded the Robert J. Trumpler Award, given by the Astronomical Society of the Pacific to recognize a recent PhD thesis considered unusually important to astronomy. He is the third IfA gradute to receive the award in the past five years.
When it comes to extrasolar planets, appearances can be deceiving. Astronomers from Hawaiʻ and elsewhere have imaged a new planet, and it appears nearly identical to one of the best studied gas-giant planets. But this doppelgänger differs in one very important way: its origin.
A multinational team of scientists has just found the first fragments of the small asteroid 2018 LA, which exploded harmlessly high above Africa on June 2. The University of Hawaiʻi's Asteroid Terrestrial-Impact Last Alert System (ATLAS) telescope took the final images of 2018 LA before it entered Earth's atmosphere and exploded.
Astronomers and physicists around the world, including here in Hawaiʻi, have begun to unravel a long-standing cosmic mystery. Using a vast array of telescopes in space and on Earth, they have identified a source of cosmic rays-highly energetic particles that continuously rain down on Earth from space. In a paper published this week in the journal
The interstellar object ʻOumuamua was discovered back on October 19, 2017, but the puzzle of its true nature has taken months to unravel, and may never be fully solved. Today, an international team led by IfA graduate Marco Micheli and IfA Astronomer Karen Meech reports that it might be a comet, and not an asteroid as initially thought.
Four current and former doctoral students from the University of Hawaiʻi at Mānoa Institute for Astronomy (IfA) have been recognized for outstanding research.
University of Hawaiʻi at Mānoa astronomer John Tonry has been named as one of the National Academy of Sciences' 84 newly chosen members.
