Latest Metallicity Stories
There is more than one way to make a dwarf galaxy, and NASA's Galaxy Evolution Explorer has found a new recipe.
Cosmic explosions known as gamma-ray bursts are curiously picky about where they explode. Shunning spiral galaxies like the Milky Way, gamma-ray bursts prefer to 'go off' in oddball star systems that astronomers are just beginning to understand.
Although the universe contains billions of galaxies, only a small amount of its matter is locked up in these behemoths. Most of the universe's matter that was created during and just after the Big Bang must be found elsewhere.
Millions of clustered stars glisten like an iridescent opal in a new image from NASA's Spitzer Space Telescope. Called Omega Centauri, this sparkling orb of stars is like a miniature galaxy.
Astronomers have at last found definitive evidence that the universe's first dust â€“ the celestial stuff that seeded future generations of stars and planets â€“ was forged in the explosions of massive stars.
Astronomers have long thought that globular star clusters had a single "baby boom" of stars early in their lives and then settled into a quiet existence.
A recent study brings new insight into how planets form around red dwarfs, the most populous stars in the Milky Way galaxy.
New observations from NASA's Spitzer Space Telescope strongly suggest that infrared light detected in a prior study originated from clumps of the very first objects of the Universe.
A new image from NASA's Spitzer Space Telescope is helping astronomers understand how stardust is recycled in galaxies. The cosmic portrait shows the Large Magellanic Cloud, a nearby dwarf galaxy.
The components of life may have been under attack in the hostile environments of the universe's first galaxies, say astronomers using NASA's Spitzer Space Telescope.
