Latest Wolf-Rayet star Stories
Using radio and infrared telescopes, astronomers have obtained a first tantalizing look at a crucial early stage in star formation.
The stars we see today weren't always as serene as they appear, floating alone in the dark of night. Most stars, likely including our sun, grew up in cosmic turmoil - as illustrated in a new image from NASA's Spitzer Space Telescope.
Some of the oldest stars in the Milky Way – a kind of stellar fossils in the outer reaches of our galaxy, contain abnormally large amounts of heavy elements like gold, platinum and uranium.
The very first stars in our universe were not the behemoths scientists had once thought, according to new simulations performed at NASA's Jet Propulsion Laboratory, Pasadena, Calif.
Exploding stars are the "factories" that produce all the heavy elements found, among other places, in our bodies.
Five billion years from now, our Milky Way galaxy will collide with the Andromeda galaxy.
Researchers at the University of Warwick have found a unique feuding double white dwarf star system where each star appears to have been stripped down to just its helium.
New observations by University of Michigan astronomers add weight to the theory that the most massive stars in the universe could form essentially anywhere, including in near isolation; they don't need a large stellar cluster nursery.
A giant star in a faraway galaxy recently ended its life with a dust-shrouded whimper instead of the more typical bang.
A spectacular new image from ESOâ€™s Wide Field Imager at the La Silla Observatory in Chile shows the brilliant and unusual star WR 22 and its colorful surroundings.
Star -- A star is a self-gravitating sphere of plasma in hydrostatic equilibrium that generates energy in its interior through the process of nuclear fusion. Energy from this process radiates into space as electromagnetic radiation and neutrinos. Star formation and evolution As learned by star formation astronomers, stars are born in molecular clouds, regions of higher density of matter, and form by gravitational instability inside those clouds. High mass stars illuminate powerfully...
