This stunning fisheye photograph shows the towering wonder of the European Southern Observatory’s Very Large Telescope—plus, you know, some galaxy called the Milky Way in the background, too.

For the first time ever, astronomers have identified a small planet with a ring system. They previously thought that such a phenomenon could only happen on large planets like Saturn and Jupiter. But this special space rock, known as 10199 Chariklo, is a small planet called a Centaur.

Astronomers have a good day when they detect one planet inside a star system’s habitable zone. A mostly European team of researchers must be giddy, then, as it just found three of those ideally located planets around Gliese 667C. The group has combined existing observations from the ESO’s Very Large Telescope with new HARPS telescope data to spot the trio of super-Earths, all of which could theoretically support liquid water. As long as the discovery holds up, it may have a big impact on exoplanetary research: it shows both that three super-Earths can exist in one system and that more than one survivable planet can orbit a low-mass star. We can only do so much with the findings when Gliese 667C is 22 light-years away, but it’s good to learn that space could be more human-friendly than we once thought.

Combine a state-of-the-art telescope with a 268-megapixel camera, point it at the sky, add in a bit of calculation and you could end up with a gorgeous photo of the Carina Nebula. That’s exactly what the ESO’s Paranal Observatory in Chile did recently with its brand new VLT Survey Telescope — just a portion of the resulting inaugural image is shown above. This isn’t the first time the ESO has shown a love for large captures: it managed to stitch together a massive 9-gigapixel image of the Milky Way out of thousands of photographs taken with its VISTA telescope earlier this fall. However, with the 2.6-meter VLT and 268-megapixel OmegaCAM camera, the observatory is able to capture huge swaths of sky at a time — no need for stitching here. The ESO says that it’s the “largest telescope in the world exclusively dedicated to surveying the sky at visible wavelengths.” As for the Carina Nebula, the star formation region is a popular choice among astronomers trying out new telescopes, and seeing how mesmerizing it is, we can’t fault them for it.

They say a picture is worth a thousand words, but this just leaves us speechless. Pictured above is a compressed 108,500 x 81,500 pixel image of 84 million stars across central parts of the Milky Way. Taken by the VISTA survey telescope at the ESO’s Paranal Observatory in Chile, this 9-gigapixel photo is the result of thousands of individual images being meshed together. If it were printed out at the average resolution of a standard book it would measure a mind-boggling 9 x 7 meters. Using three separate infrared filters, VISTA is able to see through dust fields that normally obscure the view of an optical telescope. By studying this monumental image, astronomers hope to gain a better understanding of how galaxies form and evolve.

Infrared telescope can pick out the atmosphere on distant planets, smell what the aliens are smelling
Posted in: Today's Chili 
Astronomers in Chile using the European Southern Observatory’s Very Large Telescope are now able to analyze the atmosphere on faraway planet Tau Bootis b. Using CRIRES, a supercooled infrared spectrograph bolted to the ‘scope, the team was able to judge the size of the exoplanet — and for the first time, take a reading of the atmosphere while not in transit. Historically, the only time researchers have been able to conduct atmospheric analysis is during the transit of its nearby star, which imprints the qualities of the atmosphere onto the light. The team found that Tau Bootis b is around six times the size of Jupiter, but its air is so thick with Carbon Monoxide that we’ll have to look elsewhere to plan that expedition to the stars.
