For the first time EVER, galaxy researchers have taken pictures of planets orbiting a sun-star, much like our own. The first, taken by the much beloved Hubble Telescope, shows a planet orbiting the bright southern star Fomalhaut, located 25 light-years away in the constellation Piscis Australis. The second picture, snapped by upstaging Hawaiian observatories Gemini and Keck, shows two young planets orbiting a completely different star located 130 light-years from us! Take that Hubble! But I warn you—like the ultrasounds your friends show you of their three-month old fetus—these pictures wow mostly because of what they are, not because of what they look like.

This is what the Hubble Telescope saw, conveniently labeled by our friends at NASA. Where is the planet, you ask? Do you see that little underlined part to the right? That's the unimaginatively named Fomalhaut b! To get the image, Hubble's camera needed to block out the brightest part of the star, which shines millions of times brighter than the planet itself.

And here's the picture taken by the Gemini and Keck observatories of the bodies orbiting Star HR8799. HR8799 is about 1.5 times more massive than our sun, and five times more luminous. Like the Hubble's image, this star needed to have its light blocked too in order for us to see the planets. These two, despite being an even greater distance away, were slightly easier to find since they're young. Being only about 60 million years old, they're still glowing from leftover heat from their formation, making them brighter than Fomalhaut B, which only glows when reflecting light from Fomalhaut.

Here's an artistic rendering of Star HR8799 and it's planets. The third planet hasn't been imaged yet, but thanks to mathematical calculations, we know it's there!

So in case you were doubting it—yes, other star systems exist. And as our galactical camera technology gets better, the pictures will start looking more like actual planets, rather than fetal specks on a giant Eye of Sauron. [Bad Astronomy]

<![CDATA[Hubble Resumes Operations, Sends Back Picture of Lost Starfox 64 Level]]> The Hubble Telescope, which was quite nearly lost this month to a combination of old age and a fritzy 486, has resumed "regular science operations" today, and sent back this spectacular picture of a pair of galaxies engaging in some kind of celestial slow dance. The mission to replace the Science Instrument Command and Data Handling unit (SIC&DH), the temperamental system at the heart this whole debacle, is planned for April of next year. Until then we'll be able to depend on a steady supply of cosmo-porn, courtesy of the Hubble's backup systems.

Surprisingly, the replacement SIC&DH, which will undergo extensive testing starting in mid-December, will be constructed from hardware of the same vintage as the hilariously old version that keeps flipping out in space right now. Whatever works, I guess.

Even by Hubble standards, the latest picture is pretty amazing. As much I'd like to start off on a some kind of Saganesque soliloquy about sand, whales and the vastness of space, I can't because this picture looks exactly like every third Starfox 64 level. Seriously NASA, are you playing some kind of trick on us? Is the Hubble really OK? Is space even real? [NASA via The Register]

<![CDATA[Hubble's 486 Backup Computer Wakes Up For the First Time Since 1990]]> Prospects were starting to look pretty grim for the venerable Hubble telescope. Following a communications breakdown, the Hubble team postponed their scheduled repair mission from October 14th until this coming February, at the earliest. Until then, the Hubble's usable data transmission abilities were dependent on one thing: the successfully booting of a 486 backup system, last powered on before the Hubble Launch over 18 years ago. Well, the Hubble team has now reported that the dusty old computer seems like it's working just fine.

NASA scientists won't be sure of their success until the computer proves capable of executing mission-critical commands and/or playing through the entirety of Escape From Monkey Island, but their hopes are high for both possibilities. [NASA via The Register]

<![CDATA[NASA Pics Celebrate Hubble's 18th Birthday, Space Telescope Still Can't Drink Beer]]> Eighteen years ago today, the Hubble Telescope was launched into space by the Space Shuttle Discovery. To celebrate its coming of age, NASA has released 59 high-definition breathtaking pictures of galaxies colliding across the universe. Above is ESO 99-4, a weird-shaped galaxy (probably the result of another collision) situated in the Triangulum Australe, around 400-million light years away from earth. [Wired]
