Crab Nebula

A supernova remnant that astronomers dubbed the Crab Nebula is the only remaining trace of a huge stellar explosion that observers on the ground in China and Japan chronicled in 1054.

A riddle inside a mystery

Planetary nebula known as ESO 456-67 in the constellation of Sagittarius (The Archer), in the southern sky. Basically, this is an image of shells of dust and gas pushed outwards from a dying star. What you see at the center is the remnant of the original star. What's to explain the different shapes? Scientists are still trying to answer that question.

Large Magellanic Cloud

The Large Magellanic Cloud, a satellite galaxy of the Milky Way, is about 200,000 light-years from Earth. The collapsing clouds of gas within it form new stars. New stars are being born in the glowing nebulae.

A ring galaxy to remember

Not much is known about ring galaxies like the one pictured here dubbed Zw II 28. The assumption is that they are formed after galaxy collisions, forming a dense central core circled by bright stars.

How's the weather out there?

Hubble data helped NASA create the most detailed weather map yet for a brown dwarf named 2MASSJ22282889-431026. Brown dwarfs are created from condensed gas, but they lack the mass to fuse atoms and produce energy.

Space junk -- and then some

A new spin on space junk -- in this case a vast debris disk around the star Fomalhaut. The image also turns up an unidentified mysterious planet circling the star.

Oldest star in our galaxy

The oldest star in our galaxy whose age astronomers can determine is called HD 140283. It's estimated to be 14.5 billion years (give or take 800 million years) and is estimated to be 190.1 light-years away from Earth

460 light-years away from Earth

About 460 light-years away from Earth resides an object known as HH 151, essentially a bright jet of glowing material trailed by an orange-hued plume of gas and dust. It is located in the constellation of Taurus.

NGC 411: Looking good for 1 billion years old

A collection of approximately 150 extremely old stars inhabits our galaxy. They all look a lot like NGC 411, pictured here. But NGC, which was formed from the same gas cloud, is a relative youngster, at an estimated billion years old.

A transitional phase for a 'young' star-forming galaxy

The galaxy in this image, 2MASX J09442693+0429569, has been in a near-constant state of formation for the last billion years, and the process only stopped relatively recently.
