The European Southern Observatory's Very Large Telescope (VLT) has captured a beautiful image of the planetary nebula ESO 577-24. The ionized mass of gas and dust is only expected to be visible ...

A dying red giant star and the remains of a stellar companion it shredded long ago have created a rare and short-lived planetary nebula.

Before a white dwarf and a planetary nebula, this is a living star's final stage.

Scientists have been receiving X-ray signals from the Helix Nebula for decades, but now they believe it may hide a horrifying and grisly secret.

The spectacle began around 4,000 years ago, when the Nebula Ring's central star, which was more massive than our sun, expelled gases from its outer layers into space.

Gazing into a planetary nebula 2,500 light-years away in space may remind people the sun will eventually die, too. WIll it also go out with a light show?

So far, only three star clusters are known to contain a planetary nebula. "None of their central stars had been studied before because they are all very distant and faint,” Werner says.

The Helix Nebula, located 650 light-years from Earth, has baffled scientists for decades. The planetary nebula was created by a dying star that shed its outer layers of gas, leaving behind a small ...

This second star shapes the transformation into a planetary nebula, much as a potter shapes a vessel on a potter’s wheel.
