A decades-old cosmic mystery may finally be solved. Scientists now suspect that the strange X-ray glow from a distant white ...

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 ...

This image features a deep field view of the Cassiopeia constellation immersed in the glow of ionized hydrogen gas, where the ...

A not-so-distant white dwarf named WD 2226-210 has been on our radar since the 1980s for releasing X-rays, now we may know ...

For over 40 years, astronomers have been puzzled by strange X-ray signals from the Helix Nebula’s white dwarf. Now, they may ...

New research suggests that life could have the time and energy to arise on Earth-like worlds in the rapidly shrinking ...

Astronomers have traced a starnge blast of radiowaves that repeats every 2 hours back to a dead star white dwarf magnetically ...

Scientists already know that a planet must be in the “Goldilocks zone”—not too hot and not too cold—to have liquid water, a ...

Now, astronomers have zeroed in on the surprising origin of the unusual radio pulses: a dead star, called a white dwarf, that is closely orbiting a small, cool red dwarf star. Red dwarfs are the ...

Astronomers have discovered that a pair of stars—one white dwarf and one red dwarf—are sending out radio pulses every two ...

That isn't the case with white dwarfs, which form when stars like the sun run out of fuel for nuclear fusion, shedding their outer layers as their cores collapse and forming a cooling stellar ember.
