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

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

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

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

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 ...

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

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 ...

"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 ...

The emission nebula, known as Sh2-284, is an immense region of gas and dust that fuels new star formation. It lacks elements ...

Astronomers have been recording the signal for more than four decades, but this is the first time they've nabbed its origin.

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

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 ...
