Stunning Hubble photo catches an aging star's giant ring of space gas
Although it looks more like an entity seen through a microscope than a telescope, this rounded object, named NGC 2022, is certainly no alga or tiny, blobby jellyfish. Instead, it is a vast orb of gas in space, cast off by an ageing star. The star is visible in the orb's centre, shining through the gases it formerly held onto for most of its stellar life.  When stars like the Sun grow advanced in age, they expand and glow red. These so-called red giants then begin to lose their outer layers of material into space. More than half of such a star's mass can be shed in this manner, forming a shell of surrounding gas. At the same time, the star's core shrinks and grows hotter, emitting ultraviolet light that causes the expelled gases to glow.  This type of object is called, somewhat confusingly, a planetary nebula, though it has nothing to do with planets. The name derives from the rounded, planet-like appearance of these objects in early telescopes. NGC 2022 is located in the constellation of Orion (The Hunter). Credit: ESA/Hubble & NASA, R. Wade

Just like people, stars get old. Also like people, aging stars release a lot of gas.

This newly captured image from the Hubble Space Telescope shows us NGC 2022, a planetary nebula in the Orion constellation. Yes, it's a star and not a planet; it's called that because of the rounded shaped produced by the star's expanding ring of gas.

As stars get older, they get larger and take on more of a reddish glow. As that process plays out, the star sheds its outer layers into the surrounding space. As its mass shrinks the star's core gets hotter, which in turn releases more ultraviolet light.

Those UV rays create a distinctive glow in the surrounding space as they interact with the gases that have been released. That's how we end up with this picturesque scene.

The image above is a little bit cut off; here's the whole thing:

While NGC 2022 presents a striking image, not all planetary nebulae are created equally. Their shapes and colors are dictated by a variety of factors, though like most photos of deep space, they all share the common element of being out-of-this-world beautiful.

You can search through the Hubble website to see plenty of other examples, like this one captured in Nov. 2008, or this one, snapped way back in 1995.
