A star system, located 3,000 light-years away from Earth, is predicted to become visible to the unaided eye soon. This could be a once-in-a-lifetime viewing opportunity as the nova ouburst only occurs about every 80 years.
A white dwarf star that devoured at least a chunk of one of its planets has been betrayed by a scar of vaporized metal marring it surface – the tell-tale remnants of the planet that once orbited the star before spiraling into its doom.
If confirmed, these would be the first directly-imaged planets that are similar to the giant planets in our own Solar System, and they would demonstrate that widely separated giant planets like Jupiter survive stellar evolution.
Astronomers have just found a second example of a white dwarf acting as a pulsar, following the first discovery in 2016.
A group of Australian space scientists discovered a white dwarf star that appears to be in the beginning stages of crystallizing into a celestial diamond.
Astronomers have discovered what appears to be an intact, Jupiter-size planet ( WD 1856 b ) whipping around a compact white dwarf, the remnant of a Sun-like star.
In the first observation of its kind, astronomers using the Very Large Telescope in Chile have found evidence of a Neptune-size planet orbiting a white dwarf, the collapsed remnant of a Sun-like star that has run out of nuclear fuel.
Imagine being caught in the clutches of a black hole, being whirled around at dizzying speeds and having your mass slowly but continually sucked away. That’s the life of a white dwarf star that is doing an orbital dance with a black hole.
A team of scientists reports that it has discovered the existence of a white dwarf star whose atmosphere is rich in carbon and nitrogen, oxygen and hydrogen. The white dwarf is approximately 200 light years from Earth and is located in the constellation Boötes.
University of Washington associate professor of astronomy Eric Agol has proposed that potentially habitable planets orbiting white dwarfs could be much
