State-of-the-Art Climate Model Shows That Venus Could Never Have Had Oceans
Whether Venus, one of the Solar System’s four terrestrial planets, ever had oceans remains an unsolved puzzle. Although an American study hypothesized that it did,…

Findings could advance understanding of ultra-fast outflows’ role in evolution of galaxies. When supermassive black holes have tantrums, galaxies sit up and take notice. A…
On November 19, 2021 (late evening of the 18th in some time zones), the Moon passes into the shadow of the Earth, creating a partial…
“In astrophysics, we have only this one universe which we can observe,” Mark Vogelsberger, an MIT physics professor, says. “With a computer, we can create…
These cosmic ribbons of gas have been left behind by a titanic stellar explosion called a supernova. DEM L249 is thought to be the remnant…
Recent weeks have witnessed a series of medium-to-large-sized asteroids cross paths with Earth’s orbit. The largest of the pack – asteroid 2004 UE – is…
The Hubble Space Telescope has been in ‘safe mode’ since October 23, with all of the science instruments offline and unavailable for observations. However, engineers…
A team of University of Arizona-led researchers thinks that the near-Earth asteroid Kamo`oalewa might actually be a miniature moon. A near-Earth asteroid named Kamo`oalewa could be…
Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), astronomers have discovered a small black hole outside the Milky Way by looking at how…
An international team of astronomers has published the most sensitive images of the Universe ever taken at low radio frequencies, using the International Low Frequency…
How common is our Solar System? Less common than we might think. A significant fraction of planetary systems around Sun-like stars have had a very…
A team of international scientists, including researchers from The Australian National University (ANU), have unveiled the largest number of gravitational waves ever detected. The discoveries…
An international team of astronomers led by scientists from Leiden University has for the first time characterized a dust disk surrounding a young super-Jupiter, which…
Cleopatra’s Eye, or NGC 1535, is a planetary nebula in the constellation Eridanus. This nebula has an unusual structure that is similar to the better-known…
