| First hundred thousand years of our universe Posted: 07 Aug 2013 10:45 AM PDT Researchers have taken the furthest look back through time yet -- 100 years to 300,000 years after the Big Bang -- and found tantalizing new hints of clues as to what might have happened. |
| Quasar observed in six separate light reflections Posted: 07 Aug 2013 09:59 AM PDT Quasars are active black holes -- primarily from the early universe. Using a special method where you observe light that has been bent by gravity on its way through the universe, a group of physics students have observed a quasar whose light has been deflected and reflected in six separate images. This is the first time a quasar has been observed with so many light reflections. |
| If we landed on Europa, what would we want to know? Posted: 07 Aug 2013 09:23 AM PDT Most of what scientists know of Jupiter's moon Europa they have gleaned from a dozen or so close flybys from NASA's Voyager 2 spacecraft in 1979 and NASA's Galileo spacecraft in the mid-to-late 1990s. Even in these fleeting, paparazzi-like encounters, scientists have seen a fractured, ice-covered world with tantalizing signs of a liquid water ocean under its surface. Such an environment could potentially be a hospitable home for microbial life. But what if we got to land on Europa's surface and conduct something along the lines of a more in-depth interview? What would scientists ask? |
| Posted: 07 Aug 2013 06:43 AM PDT Astronomers have recently discovered and captured an image of the least massive planet ever imaged so far -- a so-called "second Jupiter". This discovery marks an important step toward the direct imaging of much fainter Earth-like planets in the future and may lead to new models of planet formation. |
| The Odd Couple: Two very different gas clouds in the galaxy next door Posted: 07 Aug 2013 06:43 AM PDT ESO's Very Large Telescope has captured an intriguing star-forming region in the Large Magellanic Cloud -- one of the Milky Way's satellite galaxies. A sharp new image reveals two distinctive glowing clouds of gas: red-hued NGC 2014, and its blue neighbour NGC 2020. While they are very different, they were both sculpted by powerful stellar winds from extremely hot newborn stars that also radiate into the gas, causing it to glow brightly. |
