First Image Of Planet-Like Body Orbiting A Star
SpacePosted by timothy on Monday January 07, @10:15PM
from the won't-be-the-last dept.
deglr6328 writes "The Gemini North Telescope has, for the first time, directly imaged a planet like body orbiting a star. The object is a brown dwarf, 55 to 78 times the mass of planet Jupiter and 14 AU distant from its parent star 15 Sge. It was imaged using adaptive optics(see also here) that correct for the blurring effect of the atmosphere using deformable mirrors. Cool!"

    Even though the "photograph" is of just two fuzzy blobs it's cool nonetheless, especially that the first thing photographed should be celestial object that we don't have in our solar system that also happens to simultaneously prove that there have to be numerous ways that solar systems are "born" in the wake of a star's formation.

    One wonders if the cosmic soup had simmered a little more or a little less if Jupiter wouldn't be a binary star. How would it affect sleep patterns? What the hell would our watches look like?

      Would we even be here?

      Considering the climactic history of Earth, it's clear that even small perturbations in its orbit and small changes in the brightness of the Sun have large effects on the climate. In a binary star system, its not at all clear that any planetary climates would ever be steady enough to allow higher life forms to develop. Neither the orbit nor the energy received from the suns would likely be stable enough.

    The distance between the substellar object known as brown dwarf and its parent star is less than that between the planet Uranus and the sun.
    Wait a minute, I thought the brown dwarf was 14 AU from its star, not 1 AU. Oh, I see. Sorry for the confusion.

    This is old news and i think i've seen it posted on slashdot before. You people don't get out much, do you. A star-orbiting was sighted a long time ago, when Adam made headlines by saying "Huh?

    I had a high school physics teacher that was a bit of a bible thumper (no offense to any thumpers out there) who insisted that we would /never/ find planets (or planet like objects)in other solar systems. It was impossible, because . Something about proof denying faith, and without faith God being nothing ... oh wait -- that was someone else.

    A brown dwarf, especially one that much larger than jupiter is not a planet, but is a star.

    So this isn't a planet orbiting a star, but would better be described as two starts orbiting each other, much like Alpha Centauri proxima (the dwarf one)

      Like the article says, brown dwarves cannot be considered stars since they do not generate energy from a thermonuclear reaction. Having said that though, they DO give off more energy than they receive from outside sources, much like Jupiter does but on a far larger scale. A good primer site for brown dwarves can be found here [bahnhof.se].

      Lastly, it is important to not confuse brown dwarves (almost stars) with white dwarves (dying stars).

      Someone needs to mod the above up; it's important. I would have rephrased the post to reflect that this was NOT the first image of a brown dwarf orbiting a star if I knew about it before I submitted the comment.

      On closer examination, the Gemini North press release [gemini.edu] does not claim to be the first to image a brown dwarf; from the site:"The faint companion is separated from its parent star by less than the distance between the Sun and the planet Uranus and is the smallest separation brown dwarf companion seen with direct imaging". It is only the CNN story that incorrectly claims this.....Hmmmm perhaps a notification [badastronomy.com] is in order.

    Until we see it moving around that other star in an ellipse, it's just some bright pixels next to some other bright pixels. Hopefully, in a few months, we'll get to see some relative motion from it.

    As you can read, as far as 1995, the Hubble Space Telescope imaged a brown dwarf orbiting a brown dwarf on Gliese 229B [stsci.edu]. Indeed, some of the US media call it "the first discovered brown-dwarf" although the discoverer was Rafael Rebolo et al at the Instituto de Astrofísica de Canarias [www.iac.es] (he and his colleagues proposed the "Lithium test" method to actually detect this substellar objetcts). You can read a short report about brown dwarf findings at American Scientist [sigmaxi.org].

    Oh never mind, I won't bother. I was going to try to explain the significance of space research, etc. For one thing, Galileo was one of the first to challenge that the Bible does not have to be the be all end all of science, and that man can learn more on his own by observing. Without telescopes and people looking at stars, we would be alot far behind where we are today, and who knows where it will bring us. It just might help unify the people of the earth some day, and then you'll be the fool for telling us it was foolish of us to discuss such things when people are dying.

    By the way, while you are on your campaign to protect innocent lives, you better take on drunk drivers, pollution, serial killers, cigarettes (maybe not innocent, but still..) AIDs victims (especially in '3rd world countries'), etc. You better get moving.

    Yeah, the pictures are pretty (awesome, if real) but I'm going to wait for pictures from the Hubble (which had better be forthcoming!) before I'm totally persuaded.

    That said - 58 light years? That's a long trip, but totally possible.
