A new analysis of data from the 1978 Pioneer Venus mission, by researchers at Cal Poly Pomona, finds evidence not only for phosphine, but also possible chemical disequilibrium in Venus’ atmosphere, an additional possible sign of biological activity.

Whether the raindrop is made of water on Earth, methane on Titan, or liquid iron on an alien world, a new study shows that all raindrops will fall to the ground at a similar size.

Small asteroid 2021 GW4 will pass extremely close to Earth on Monday, April 12, 2021. It’ll pass just 12,313 miles (19,816 km) from Earth’s surface, or about 5% the Earth-moon distance.

Astronomers detected a new, nearby, repeating fast radio burst, originating from a spot near the great spiral galaxy M81.

NASA’s Juno spacecraft – whose mission in orbit around Jupiter was recently extended to 2025 – has been used to discover a rapidly expanding auroral ring at the very fringes of the Jovian magnetosphere.

An international team of astronomers has mapped a piece of the cosmic web without using bright quasars for the first time. They did it by turning a powerful instrument to a single region of the sky for hundreds of hours.

Data from ESA’s Gaia star-mapping satellite have revealed tantalizing evidence that the famous V-shaped Hyades – nearest star cluster to our sun – is being disrupted. The culprit may be a suspected population of dark matter sub-halos. Wow!
