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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

Astronomers have captured a striking new image of the Helix Nebula. A new picture, taken in infrared light, reveals strands of cold nebular gas that are invisible in images taken in visible light, as ...

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 ...

One of the most amazing objects in the sky is the Helix Nebula, an expanding cloud of gas and dust surrounding a dying star. This type of object is called a planetary nebula, and it’s formed when a ...
