"The idea was for our payload to get us just up to the potential biosignature designation and have the rest of the story told by instruments here on Earth."

Radio astronomy took another step forward recently, with the completion of Phase III of the Murchison Widefield Array (MWA) in Western Australia. We’ve reported before on how the MWA has investigated everything from SETI signals to the light from the earliest stars. WIth this upgrade, the MWA will continue to operate with much needed improvements while the radio astronomy awaits the completion of the successor it helped enable - the Square Kilometer Array (SKA).

Jupiter hosts the brightest and most spectacular auroras in the Solar System, and its largest moons (the Galileans) create their own auroral signatures known as “satellite footprints” in the planet’s atmosphere. Until now, astronomers had detected the auroral signatures of three Galileans (Io, Europa, and Ganymede), but not Callisto. Thanks to an international team, close-up images of Callisto's footprints have been seen at last.

The JWST is performing a new multi-wavelength survey called MINERVA (Medium-band Imaging with NIRCam to Explore ReVolutionary Astrophysics). It'll study four extragalactic fields in greater detail and depth, and will help us understand the Cosmic Dawn.

Astronomers struggle to detect small exoplanets directly. One tool they use is to search for the effects these planets have on debris disks around stars. Clues in these disks tell astronomers where they can find sub-Jupiter mass exoplanets.

By combining the information storage capabilities of DNA with a design inspired by a cassette tape, researchers have created a storage medium that can hold 36 petabytes of data
