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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

This image was created from images through blue, green and red filters and the total exposure times were 12 minutes, 9 minutes, and 7 minutes, respectively. Astronomers have obtained a deep new image ...

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 ...

2. The images are a composite of data from NASA’s Hubble Space Telescope and the Spitzer Space Telescope, combining visible and infrared light. 3. The Helix Nebula is a planetary nebula, formed from ...

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 ...

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 ...
