Now 8 years into its travels in the deep reaches of space between the stars, Voyager 1 has detected a faint, low-level hum. It stems from the vibration of the plasma, or ionized gas, in interstellar space.

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.

The core stage of China's Long March 5B rocket - which launched the Tianhe space station module - plummeted into the Indian Ocean on May 8, 2021. In a statement issued that day, new NASA administrator Bill Nelson criticized China's handling of the re-entry.

If humanity wants to travel between stars, people are going to need to travel faster than the fastest-moving stuff known in our universe: light. New research suggests that it might be possible to build warp drives and beat the galactic speed limit.

A couple of charts from master chart-maker Guy Ottewell, showing Mercury in the sky now and throughout 2021. Plus a word about a lost whale ...

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.
