A Super Discovery, 05.11.12

NASA’s Spitzer Space Telescope has made another monumental discovery: a “super-Earth.”

Twice as big as Earth, the super-Earth is, for now, called 55 Cancri e, and is situated in the constellation Cancer, about 41 light years away. For the first time, scientists were able to actually measure the light emanating (reflected) from the planet itself, instead of measuring how much light it blocks as it transits in front of its star. Because of the low measure­ments that were taken, scientists guess that the planet is probably very dark most of the time. It appears to be tidally locked, though (one side is stuck facing its star), and that side appears to have temperatures in excess of 3,000 Fahrenheit. Just so we’re clear on how hot that is, most kinds of metal will be liquid at that temperature.

Based on their observations, scientists are saying the planet most likely has a rocky core and is covered with water. Be­cause of the extreme heat on the sunny side, however, the water is probably in a “supercritical” state, where it exists as both liquid and gas. NASA claims the atmosphere is covered with steam. Regardless, the atmosphere appears to be very thin, as it is doing such a poor job of blocking its sun’s heat.

Based on all observations made at this point, the planet cannot support life.

Amateur astronomer captures photo of young solar system, 12.02.11

An amateur astronomer in New Zealand has managed to take and clean up a photograph of a new solar system in the works. The stunning part? He was doing it with his own, homemade, 10-inch telescope. That’s some pretty good aim!

The system is Beta Pictoris, 63 light-years away in the southern hemisphere. The system had been photographed a number of years ago by professional astronomers, but the fact that Rolf Olsen managed to first of all find the system, then photograph it and do such a good job that the “circumstellar disc” was visible, is astounding.

The circumstellar disc is the cloud of dust and debris orbiting around the star. Eventually, it should turn into planets and various other satellites. Olsen was able to expose it using a very long, detailed set of instructions that had been published in a study on the system. That he was able to achieve such good results shows again that anyone can make a contribution to astronomy if they wish.

“There certainly could be a lot of interesting things that professional astronomers have missed, that amateur astronomers could clue us in on,” wrote Bryce Croll, an astronomer at the Massachusetts Institute of Technology, in an email to SPACE.com about Olsen’s achievement. So, hang in there, sky watchers! You just might be the next one to have a breakthrough.
