We're seeing other systems that are all over the map, so that in itself is interesting.
This is really a huge step for us to start to fill in what we know about the universe around us."This artist’s impression shows the planet HD 85512b orbiting the Sun-like star HD 85512 about 35 light-years from Earth.
That's been rewritten multiple times now, and it gets back to the idea that part of science, and part of understanding the world we live in, is casting our net wider and looking at new things."The moon, which has temporarily been named P4, is estimated to be 8-to-21-miles (13-to-34-kilometers) wide.
Pluto's largest moon, Charon, is 648-miles (1,043-km) wide, and the two others, Nix and Hydra, range from 20-to-70-miles (32-to-113-km) across.
The yellow lines are the measured tracks of other particles produced in the collision.
The pale blue volume shows the CMS crystal calorimeter barrel.2.This planet is about 3.6 times as massive as the Earth is at the edge of the habitable zone around the star, where liquid water, and perhaps even life, could potentially exist.But Kepler is not alone in its hunt for alien worlds.NASA's Mercury Messenger probe captured this historic image of Mercury, the first ever obtained from a spacecraft in orbit about the solar system's innermost planet.The photo was taken on Tuesday (March 29) at am EDT.4.Mc Nutt recently spoke with about some of the most significant astronomical events and findings of the year.In no particular order, here are the 11 best astronomy stories of 2011:1.A telescope from the European Southern Observatory that searches for signs of exoplanets also made enticing finds this year.The High Accuracy Radial velocity Planet Searcher instrument, or HARPS, found more than 50 new alien planets, including one super-Earth that could potentially support life.As researchers continue to sift through data from Kepler, HARPS and various other instruments, exoplanet research is not showing any sign of slowing down.A typical candidate event at the Large Hadron Collider (LHC), including two high-energy photons whose energy (depicted by red towers) is measured in the CMS electromagnetic calorimeter.
