The supernova mechanism behind cosmic dust formation has been a mystery, but now astronomers have the answer. Continue reading →
Behind the nebulous beauty of this newly-released portrait of a stellar nursery is a violent battle that will end only one way: The death of Gum 15. Continue reading →
Astronomers aren't being poetic when they say this star is a diamond.
In an effort to visualize what a future starship may look like, NASA physicist Sonny White and space artist Mark Rademaker have teamed up to create the 'IXS Enterprise.'
Red dwarf stars -- the most common stars in the galaxy -- bathe planets in their habitable zones with potentially deadly stellar winds, a finding that could have significant impacts on the prevalence of life beyond Earth, new research shows.
NASA's Spitzer Space Telescope has uncovered the darkest cloud of interstellar dust and gas ever seen; it is so dense that even background infrared radiation is blocked, casting an ominous interstellar shadow. Continue reading →
Astronomers have long been in the dark about what is happening just beyond the center of the Milky Way -- but with the help Cepheid variable stars, we're beginning to realize that our galaxy's outer disk is mysteriously flared.
When two galaxies collide, the mingling interstellar gases are violently turbulent. Turbulence should switch off any star formation, but galactic mergers are known to be fertile grounds for stellar birthing -- what's going on? Continue reading →
