Since the 1980s, a strange X-ray emission has puzzled astronomers. At the heart of the Helix Nebula, a dying star may have ...

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

Powerful jets and radiation winds from two protostars are slamming into the nebulosity around them, sculpting the nebula.

"We might have finally found the cause of a mystery that's lasted over 40 years," said researcher Sandino Estrada-Dorado.

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 ...

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

After tracking a puzzling X-ray signal from a dying star for decades, astronomers may have finally explained its source: The old star might have destroyed a nearby planet. Dating back to 1980, X ...

"The goal of this project was to explore the fundamental low-mass limit of the star and brown dwarf formation process." ...

An curved arrow pointing right. The Orion Nebula is a giant gas cloud 1,344 light years away. It's also a cosmic factory for producing new stars. Astronomers recently observed over 900 small ...

Since they were first detected over four decades ago, unusually powerful x-ray emissions originating from the site of a dying star called the Helix Nebula have proved an enigma astronomers. Now, we ...

"We think this X-ray signal could be from planetary debris pulled onto the white dwarf, as the death knell from a planet that was destroyed by the white dwarf in the Helix Nebula," said lead ...
