New measurements from Parker Solar Probe - the first new direct measurements of Venus' atmosphere in nearly 30 years - showed an unexpected natural radio signal being emitted by Venus' ionosphere. The probe made the discovery while using Venus as a "gravity slingshot" to come closer to the sun.

Astronomers have identified 5 multi-star systems that have stable habitable zones. This means that any rocky worlds that may exist in those zones could potentially have life.

On Earth, scientists study rock layers and the fossils embedded in them to learn about ancient life. A new study focused on red Mars - the desert planet - did something similar. It looked at the record of changing habitability preserved in ancient dune fields.

New research suggests that the Mars underground has the right ingredients for present-day microbial life.

The Chinese Tianwen-1 mission’s Zhurong rover will attempt to land on the surface of Mars in mid-May 2021.

NASA's Roman space telescope mission - launching sometime in the mid-2020s - is expected to find at least 100,000 new exoplanets orbiting other stars, say astronomers.

SpaceX's test flight of Starship SN15 went off without a hitch today, May 5, 2021. Following 4 Starship prototypes that exploded upon landing after their high-altitude flight tests, the SN15 landed safely.

Check out these pics from the annual Eta Aquariid meteor shower. The peak morning was likely May 5, 2021, but the following morning, May 6, might be good, too.
