A gorgeous nebula turns out to hold a surprise at its center: a pair of stars that don’t match as they should. Researchers looking at the beautiful NGC 6164/6165 nebula were surprised to learn that ...

This Hubble image shows ESO 455-10, a planetary nebula located in the constellation of Scorpius. The color image is composed of near-infrared and optical observations from Hubble’s Wide Field Camera 3 ...

This nebula measures a whopping 250 light-years across, and it’s close enough to Earth that its relative size in the sky is equivalent to that of four full Moons. But it’s so faint in the wavelengths ...

This season might be the perfect time to try to see one of the prettiest sights in the night sky. Winter is the best time to spot the Rosette Nebula, a beautiful star-forming region 5,000 light-years ...

Located 161,000 light-years away from Earth, the Tarantula Nebula has long been a favorite for astronomers studying star formation. Now, we've been given an even better look at the beautiful nebula ...

When astronomers looked at a stellar pair at the heart of a stunning cloud of gas and dust, they were in for a surprise. Star pairs are typically very similar, like twins, but in HD 148937, one star ...

Use left and right arrow keys to seek audio. NGC 2024, or the Flame Nebula, is a large star-forming region that makes up part of the Orion constellation and resides roughly 1,400 light-years away from ...

These looping, twisting tendrils of gas are the debris cloud from a tremendous cosmic explosion – an explosion whose light may have been visible to the last Neanderthals on Earth 40,000 years ago.

The Ring Nebula is a common image in astronomy, but new images from Hubble reveal something rather strange inside the cloud of swirling gas. These new images, captured by Hubble’s Wide Field Camera 3, ...

The nebula was called Medusa because poisonous snakes hung from her grotesque head, instead of hair. Those who named the nebula thought – though I’m not sure why – that the glimmering filaments of the ...

This image, taken with the VLT Survey Telescope hosted at ESO’s Paranal Observatory, shows the beautiful nebula NGC 6164/6165, also known as the Dragon’s Egg. The nebula is a cloud of gas and dust ...
