A European team of astronomers using ESO’s Very Large Telescope (VLT) has measured the distance to the most remote galaxy so far. By carefully analysing the very faint glow of the galaxy they have found that they are seeing it when the Universe was only about 600 million years old (a redshift of 8.6). These are the first confirmed observations of a galaxy whose light is clearing the opaque hydrogen fog that filled the cosmos at this early time. - Credit: ESO

The Tug of Exoplanets on Exoplanets – Earlier this year, I wrote about how an apparent change in the orbital characteristics of a planet around TrES-2b may be indicative of a new planet, much in the same way perturbations of Uranus revealed the presence of Neptune. A follow up study was conducted by astronomers at the University of Arizona and another study on planet WASP-3b also enters the fray. -Jon Voisey / Universe Today

Spring Has Sprung … On Titan – NASA’s Cassini spacecraft has sent back dreamy raw images of Saturn’s moon Titan that show the appearance of clouds around the moon’s midsection. These bright clouds likely appeared because the moon is changing seasons and spring has arrived in Titan’s northern hemisphere. -NASA/JPL

At least one, and possibly two Space Shuttles are also scheduled to visit the station next year. -NASASpaceFlight.com

Watching the Sun – After the deepest solar minimum in 100 years, the sun is finally kicking into high gear. According to Space Weather, the sun spent 260 days without any sunspots in 2009; in 2010, so far, that number has plummeted to 45. -Heather Goss / Aviation Week

Could a Human Mars Mission Be Funded Commercially? – What will it take to actually get humans to Mars? The best answer is probably money. The right amount of cold, hard cash will certainly solve a lot of problems and eliminate hurdles in sending a human mission to the Red Planet. But cash-strapped federal space agencies aren’t currently in the position to be able to direct a mission to another world – at least in the near term – and seemingly, a trip Mars is always 20-30 years off into the future. But how about a commercially funded effort? -Nancy Atkinson / Universe Today

Jupiter and Uranus at opposition

Recorded on September 27, this well-planned composite of consecutive multiple exposures captured Jupiter and Uranus in their remarkable celestial line-up accompanied by their brighter moons. The faint greenish disk of distant planet Uranus is near the upper left corner. Of the tilted planet's 5 larger moons, two can be spotted just above and left of the planet's disk. At the right side of the frame is ruling gas giant Jupiter, flanked along a line by all four of its Galilean satellites. Farthest from Jupiter is Callisto, with Europa and Io all left of the planet's disk, while Ganymede stands alone at the right. - Credit: Peter Knappert / APOD

Saturn’s Rings Formed from Large Moon’s Destruction – The formation of Saturn‘s rings has been one of the classical if not eternal questions in astronomy. But one researcher has provided a provocative new theory to answer that question. Robin Canup from the Southwest Research Institute has uncovered evidence that the rings came from a large, Titan-sized moon that was destroyed as it spiraled into a young Saturn. -Nancy Atkinson / Universe Today

Trojans May Yet Rain Down – In the past decade Neptunian Trojans have been discovered. By the end of this summer, six have been confirmed.
