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 ...

What makes this confirmation especially intriguing is the planet's survival in the so-called "forbidden zone" of its star — a region so close to the white dwarf that any world within should have been ...

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

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

T Coronae Borealis, a binary star system about 3,000 light years away, is usually far too dim to see with the naked eye.

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 ...

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 ...

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

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 ...
