At the heart of the double-lobed Toby Jug planetary nebula is the red-giant star HR3126, which at just 50 million years old, is considerably younger than the 4.6-billion-year-old sun. HR3126 ...

Thanks to the James Webb telescope, we can now see the nebula with more clarity. As one expert says, "We always knew planetary nebulae were pretty. What we see now is spectacular." ...

A nebula is formed from the dying star's outer envelope, which is puffed off into space following the star's red giant phase. The Southern Ring Nebula was imaged in December 2022 by the James Webb ...

New observations of red giant stars suggest that massive planets or other objects orbiting dying stars help stir up stellar winds and shape planetary nebulae, researchers report in the Sept. 18 ...

Some of the sharpest images ever made with ESO’s Very Large Telescope have, for the first time, revealed what appears to be an ageing star giving birth to a butterfly-like planetary nebula ...

Using the James Webb Space Telescope (JWST), astronomers have observed enigmatic rings in the planetary nebula NGC 1514, ...

“We don’t know very much about how planetary systems behave after their star transitions from a red giant to a super long-lived white dwarf,” says Paul Byrne, a planetary scientist at ...

It’s inevitable; in about 5 billion years our sun will burn up all of the hydrogen in its core, then it will swell into a red giant, eating Mercury and Venus before collapsing.

The aptly named Egg Nebula, lying 3,000 light-years away in the constellation Cygnus, is a protoplanetary nebula. Skip to content Introducing the all-new Astronomy.com Forum!

This might look like some weird cosmic gateway straight out of 2001: A Space Odyssey or a particularly trippy old-school Doctor Who adventure, but the Red Square Nebula is completely real.

The Red Rectangle Nebula doesn’t merely look modern-art cubist bizarre. Its very light is strange, its composition is food for philosophy, and it remains a hot venue of current research. Located ...
