In this image from NASA's Spitzer Space Telescope, "cometary knots" on the Helix Nebula show blue-green heads caused by excitation of their molecular material from shocks or ultraviolet radiation. An ...

A bunch of rowdy comets are colliding and kicking up dust around a dead star, according to new observations from NASA’s Spitzer Space Telescope. The dead star lies at the center of the ...

Our spectacular view of a nearby planetary nebula was captured by luck when the Hubble Space Telescope was turned around to avoid damage from a meteor storm – directly towards the Helix Nebula. While ...

NASA has taken to its exoplanets X account to highlight an image captured by multiple of its telescopes, writing "something's watching". The space agency explains in its X post that it appears the ...

This color-composite image of the Helix Nebula was created from images obtained using the the Wide Field Imager, an astronomical camera attached to the 2.2 meter Max-Planck Society/ESO telescope at ...

Washington, DC — The Helix Nebula (NGC 7293) is a challenging stargazing target for amateur astronomers. It is one of the closest planetary nebulas — a type of nebula formed from gas ejected by a ...

Now that the seasons have changed, spooky season has officially arrived. It’s once again that time of the year where anyone and everyone from Spirit Halloween to NASA aims to get as spooky as possible ...

Warning: that links to a 7 Mb image, but it’s very pretty. What you’re looking at is one of my favorite kinds of cosmic critters: a planetary nebula, specifically, the Helix Nebula. When a star like ...

When a star like the Sun runs out of fuel, it expands and its outer layers puff off, and then the core of the star shrinks. This phase is known as a “planetary nebula,” and astronomers expect our Sun ...
