Interstellar Cloud

It's a "surprising discovery."

Wait, what? New research opens a whole new window into the mysterious world of black holes.

Shaped like a megaphone, the upcoming mission will map the entire sky in infrared light to answer big questions about the universe.

Since antiquity, wreaths have symbolized the cycle of life, death, and rebirth. It is fitting then that one of the best places for astronomers to learn more about the stellar lifecycle resembles a giant holiday wreath itself.

Their orbit periodically takes them through a cloud of gas, triggering flares.

Imagine a sky full of stars as bright as a full moon. If we were in this super star cluster - called Westerlund 1 - that's what we might see. The post Westerlund 1 star cluster: Imagine if we lived here first appeared on EarthSky.

JWST shows a new side of planet formation. Just 460 light-years away, the closest newborn protostars are forming in the Taurus molecular cloud. Here are JWST's astonishing insights..

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have spotted a galaxy with a never-before-seen light signature -- indicating that its gas is outshining its stars.

A new explanation for the Wow! signal suggests it was a chance detection of a furious flare crashing into a hydrogen cloud. But some researchers doubt that this idea has truly cracked the case

The universe would be filled with zombie galaxies and dead stars if not for supermassive black hole-powered 'hearts and lungs' that help slow star formation.

Captured in infrared light by the James Webb Space Telescope, the star-forming Horsehead Nebula is located 1,300 light-years away in the Orion Constellation.

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have captured the most detailed images yet of one of the most distinctive objects in our skies, the Horsehead nebula.

But try not to get your hopes up.

Black holes not only existed at the dawn of time, they birthed new stars and supercharged galaxy formation, a new analysis of James Webb Space Telescope data suggests.

All modern life shares a robust, hardy, efficient system of intertwined chemicals that propagate themselves. This system must have emerged from a simpler, less efficient, more delicate one. But what was that system, and why did it appear on, of all places, planet Earth?

When scientists detected phosphine in Venus' atmosphere in 2020, it triggered renewed, animated discussions about Venus and its potential habitability. It would be weird if the detection didn't generate interest since phosphine is a potential biomarker. So people were understandably curious. Unfortunately, further study couldn't confirm its presence.

Astronomers have discovered a "missing link" supernova that directly connects the death of a massive star to the birth of a black hole or a neutron star.

Astronomers have completed the largest and most detailed study of what triggers a star birth in the universe's biggest galaxies, using NASA's Chandra X-ray Observatory and other telescopes.

JWST is now celebrating its second anniversary in space.

Some of the strongest, longest, smallest, biggest and best reasons to celebrate space as the year comes to a close. There are a handful of awesome firsts in ...
