This is a planetary nebula named Kohoutek 4-55, a member of the Milky Way galaxy situated just 4,600 light-years away in the constellation Cygnus (the Swan). Planetary nebulae are the spectacular ...

Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a planetary nebula designated Messier 57 (also known as NGC 6720), dubbed the Ring Nebula.

At its bright center lies a group of stars known as the Trapezium. The Helix Nebula is a type of planetary nebula. While it appears like a bubble or an eye when viewed from Earth, it's actually a ...

Lagoon Nebula: Located in in the Sagittarius, this cosmic cloud displays swirling pinks and blues from young stars. It is about 4,000 light-years away from us. In this false-color image ...

“Planetary nebulae are the spectacular final display at the end of a giant star’s life,” Hubble astronomers said in a statement. “Once a red giant star has exhausted its available fuel and shed its ...

The mysterious X-rays could be the by-product of that annihilation. The Helix Nebula is an astounding ring of glowing gas with the star at its center. It was a star much like the Sun, but when it ...

"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 Sandino ...

The closest such stellar nursery to Earth lies in the Orion Nebula, just below Orion's belt. There, molecular clouds have collapsed over millions of years, forming a cluster of new stars.

The Helix Nebula resembles a technicolor explosion frozen in time. It is a planetary nebula, a halo of gas jettisoned by a star that ran out of nuclear fuel. At its center lies a white dwarf ...

The Egg Nebula is a rapidly evolving pre-planetary nebula spanning about one light year toward the constellation of Cygnus. Thick dust blocks the center star from view, while the dust shells further ...
