Radio astronomers have discovered an unusual phenomenon in recent years. They detected radio pulses from the Milky Way that last from seconds to minutes. These pulses differ from those produced by known radio-emitting neutron stars or pulsars, which typically last only milliseconds.
When they reach the end of their long evolutions, smaller stars—those up to eight times as massive as our own sun—typically become white dwarfs. These ancient stars are incredibly dense.
"The diversity of ways that white dwarf stars can blow up is much greater than previously expected." There are a lot of ways for dead stars to blow their tops. Astronomers discovered this ...
Researchers believe they've found evidence that a white dwarf may have torn a Jupiter-sized planet apart. A white dwarf is the stellar core left behind after a dying star has exhausted its ...
Explosions in the sky and explosions on land are literally worlds apart. A supernova and a land mine explosion don't seem ...
The finale of a star’s life has enthralled scientists for years, yet questions continue to surround the explosions of white dwarf stars — the most common path that stars take during the later ...
They found that a planet orbiting a white dwarf star would offer a warmer climate than one orbiting a main sequence star. Among the roughly 10 billion white dwarf stars in the Milky Way galaxy ...
