Theoretical predictions have been confirmed with the discovery of an outflow of molecular gas from a quasar when the Universe was less than a billion years old.

A quasar is a compact region powered by a supermassive black hole located in the center of a massive galaxy.

They are extremely luminous, with a point-like appearance similar to stars, and are extremely distant from Earth...

A team of astronomers, led by Arizona State University Assistant Research Scientist Tim Carleton, has discovered a dwarf galaxy that appeared in James Webb Space Telescope imaging that wasn’t the primary observation target.

Galaxies are bound together by gravity and made up of stars and planets, with vast clouds of dust and gas as well as dark matter...

Humanity’s quest to explore—and, perhaps eventually, colonize—outer space has prompted a great many ideas about how precisely to go about it.

While conventional wisdom suggests that space launch via rockets is the best way to send human beings into orbit, other “non-rocket” methods have been proposed, including a futuristic “space elevator.”

The concept of a space elevator—essentially a sky-high cable that would let humans climb into space—has been championed by some industry experts as a way to overcome the astronomical costs associated with sending people and ca...

Although solar flares have been classified based on the amount of energy they emit at their peak, there has not been significant study into differentiating flares since slow-building flares were first discovered in the 1980s. Scientists have now shown that there is a significant amount of slower-type flares worthy of further investigation.

Solar flares occur when magnetic energy builds up in the Sun’s atmosphere and is released as electromagnetic radiation. Lasting anywhere from a few minutes to a few hours, flares usually reach temperatures around 10 million degrees Kelvin...
