Among the stellar class known as red giants, Mira stars provide seventy-five percent of our galaxy's molecules including water vapor. These red giants pulsate as fast as every few months to years with their brightness varying by ten times during a cycle.

Eta Carinae is a mysterious, extremely bright and unstable star located a mere stone's throw - astronomically speaking - from Earth at a distance of only about 7,500 light years.

When a binary star system starts to transfer mass, one of the twins may well win out, leaving its companion to occupy a strange region half way between a star and a planet. A new star-type of this sort has been found, which resembles the infrared ash of a stillborn star.

The Genesis desert crash has left scientists wondering about the delicate condition of its solar wind collection. The first release of samples to the community has begun, while new tests for oxygen-isotopes may help uncover which particles might have lunar, solar or terrestrial origins.

The leading theory of how planets form is being revised because of new observations from the US Spitzer Space Telescope. The process is not as smooth and quiet as once thought, but rather the result of violent collisions between massive space rocks.

NASA&#39;s Galaxy Evolution Explorer has discovered larger and younger than expected galaxies. The NASA craft found three dozen galaxies emitting ultraviolet light at levels that would indicate supernovas are still exploding.
