Astronomers have uncovered a previously underexplored population of faint, rapidly fading remnant radio galaxies, offering new insights into what happens after supermassive black holes stop powering their enormous radio jets.This post was originally published on […]

Astronomers have discovered that the most massive galaxies in the early universe contain far more small stars than expected. As a result, these early galaxies were likely much more massive than initial measurements suggested. This […]

The NASA/ESA/CSA James Webb Space Telescope recently imaged NGC 2392 (also known as the Lion Nebula), named for its distinctive appearance, which resembles a lion’s face seen head-on.This post was originally published on this site

Readers of a certain age will remember a golden era of asteroid films, capped by two with very different endings. “Deep Impact” drove home the devastating consequences of letting a large piece of rock hit […]

Our home galaxy, the Milky Way, grew to its current size in part by consuming smaller galaxies. Now, new data from NASA’s Hubble Space Telescope show definitive evidence of a dwarf galaxy merging with the […]

In two separate papers published in Physical Review Letters, researchers investigated the nuclear reactions that take place inside supernovae and X-ray bursts—two of the universe’s most powerful explosions. Together, the findings will help scientists build […]

It’s nearly 170 million years old. It’s more than 2.5 times the size of Earth. And it’s the first exoplanet discovered and cataloged by researchers with the Wisconsin Center for Origins Research (WiCOR).This post was […]

Astronomers have discovered the first confirmed dual active galactic nucleus in a Green Pea galaxy, revealing two supermassive black holes growing at the same time inside a compact, intensely star-forming system. X-ray observations with Chandra […]

Astronomers have discovered that the jet of a distant blazar has been gravitationally lensed by an unseen source of dark matter. Led by Silke Britzen at the Max Planck Institute for Radio Astronomy in Germany, […]

A new paper has put hard numbers on a plan that’s been rattling around the astronomy community for a while now—a California company called Reflect Orbital wants to put giant mirrors in orbit and beam […]
