Nov. 20, 2008 AUSTIN, Texas — Vast Martian glaciers of water ice under protective blankets of rocky debris persist today at much lower latitudes than any ice previously identified on Mars, says new research using ground-penetrating radar on NASA's Mars Reconnaissance Orbiter. Because water is one of the primary requirements for life as we know it, finding large new reservoirs of frozen water on Mars is an encouraging sign for scientists searching for life beyond Earth. The concealed glaciers extend for tens of miles from edges of mountains or cliffs and are up to one-half mile thick. A layer of rocky debris covering the ice may have preserved the glaciers as remnants from an ice sheet covering middle latitudes during a past ice age.

Black holes are without question some of the strangest places in the universe. So massive that they hideously deform space and time, so dense that their centers are called "points at infinity," and pitch- black because not even light can escape them, it isn't surprising that so many people wonder what it would be like to visit one.
University of California, Berkeley, astronomers have discovered the largest black holes to date ‑- two monsters with masses equivalent to 10 billion suns that are threatening to consume anything, even light, within a region five times the size of our solar system.

PARIS — A rocky world orbiting a nearby star has been confirmed as the first planet outside our solar system to meet key requirements for sustaining life, scientists said on Monday. Modelling of planet Gliese 581d shows it has the potential to be warm and wet enough to nurture Earth-like life, they said. It orbits a red dwarf star called Gliese 581 , located around 20 light years from Earth, which makes it one of our closest neighbours. Gliese 581d orbits on the outer fringes of the star's "Goldilocks zone", where it is not so hot that water boils away, nor so cold that water is perpetually frozen.

Looking at the numbers above, you'll immediately notice that you are different ages on the different planets. This brings up the question of how we define the time intervals we measure. What is a day? What is a year?
ESO 510-13: Warped Hubble Heritage Team (STScI/AURA), C. Conselice (U. Wisconsin/STScI) et al., NASA The Hubble Heritage Team captured the warped structure of spiral galaxy ESO 510-13 so beautifully in this pretty space pic . Behold, the product of galactic collisions.
