Half-baked asteroids have Earth-like crust
Space
Asteroids are hunks of rock that orbit in the outer reaches of space, and scientists have generally assumed that their small size limited the types of rock that could form in their crusts. But two newly discovered meteorites may rewrite the book on how some asteroids form and evolve.

Black holes lead galaxy growth, new research shows
Astronomy
Astronomers may have solved a cosmic chicken-and-egg problem -- the question of which formed first in the early Universe -- galaxies or the supermassive black holes seen at their cores.

Astronomers use gamma-ray burst to probe star formation in the early universe
Astronomy
By analyzing the spectrum of light emitted in the afterglow of a powerful gamma-ray burst, researchers are gleaning insights into an active stellar nursery in a galaxy so far away it appears as it was 10 billion years ago.

Star Light, Star Bright, Its Explanation is Out of Sight
Astronomy
A mysterious flash of light from somewhere near or far in the universe is still keeping astronomers in the dark long after it was first detected by NASA's Hubble Space Telescope in 2006. It might represent an entirely new class of stellar phenomena that has previously gone undetected in the universe, say researchers.

Cassiopeia A comes alive across time and space
Astronomy
Two new efforts have taken a famous supernova remnant from the static to the dynamic. A new movie of data from NASA's Chandra X-ray Observatory shows changes in time never seen before in this type of object. A separate team will also release a dramatic three-dimensional visualization of the same remnant.

Stars forming just beyond black hole's grasp at galactic center
Astronomy
The center of the Milky Way presents astronomers with a paradox: it holds young stars, but no one is sure how those stars got there. The galactic center is wracked with powerful gravitational tides stirred by a 4 million solar-mass black hole.

Over the last several years, scientists have built a very convincing case that Mars hosted water, at least early in its history. Recent observations from the Mars Phoenix lander and other spacecraft show that the planet still holds vast deposits of water as ice at its poles and in soil-covered glaciers in the mid-latitudes.
