Astronomers have discovered a freezing-cold world orbiting within the so-called "forbidden zone" around a dying star in which planets are normally destroyed. The 5.8-billion-year-old white dwarf ...

Astronomers using the James Webb Space Telescope have directly detected the faint glow of a planet that’s colder than any ...

Periodic radio emissions have been discovered in a binary system of white and red dwarf stars with an orbit time of 125 ...

Scientists have just calculated that our universe will end much sooner than previously thought—although "soon" is still an ...

In simple terms, a nova event is when energy explodes from a white dwarf star. But the events can only occur in binary star systems like T Coronae Borealis, which contains a red giant star and a ...

T Coronae Borealis is a binary star system made up of a red giant and a white dwarf. According to NASA, the white dwarf orbits the red giant closely enough that it continually grabs hydrogen from ...

A mysterious cluster of 60 stars may be just another Milky Way star cluster, or it may be one of the smallest galaxies ever ...

New calculations suggest that the universe's most enduring celestial objects, such as white dwarf stars, are decaying faster than previously thought. . | Credit: Future As the story of our cosmos ...

Astronomers have long suspected that this LMC supernova remnant is the remains of a destroyed white dwarf star, but the exact details of that explosive event, called a Type Ia supernova ...

Astronomers have detected a previously unknown type of stellar explosion called a micronova involving thermonuclear blasts at the polar regions of a type of burned-out star called a white dwarf ...
