Astronomers photograph giant exoplanet in unusual large orbit

A giant gas exoplanet in an unusually large orbit has been directly imaged by astronomers via the Young Suns Exoplanet Survey (YSES). It is 20 times as far from its star as Jupiter is from our sun.

Natural radio signal buzzes in Venus’ atmosphere

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.

These 5 multi-star systems have habitable zones

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.

History of Mars’ habitability preserved in ancient dunes

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.

Mars might support microbial life, deep underground

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

NASA expects upcoming space telescope to find 100,000 new worlds

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.

See 2 black holes in cosmic dance

NASA has released a cool new visualization showing two massive black holes orbiting each other in a stunning display of light. The intense gravity and other phenomena all play a part in producing this mesmerizing display. Watch here.

1st complete view of Venus’ orbital dust ring

NASA’s Parker Solar Probe, currently studying the sun, has observed the entire dust ring that encircles the sun along Venus’ orbit. It is the first complete view of this dust band from any spacecraft.

Martian hill named to honor Curiosity scientist

NASA has given the name Rafael Navarro Mountain to a hill in Gale Crater on Mars, where the Curiosity rover has been exploring since 2012. Navarro, a mission scientist, died in January 2021 from Covid-19.

Possible life signs in the clouds of Venus

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.
