Circumstellar discs are believed to be key components in planetary formation. However, we have very little actual evidence of planets growing in the “rings” that surround young stars. So planet formation theorists were ecstatic to learn that two new papers in Astrophysical Journal Letters describe a planet that is actively forming in the gap it most likely created in the ring system of a young, Sun-like star. from Universe Today https://ift.tt/wZQVaLC via IFTTT

After the formation of the Solar System, it took a maximum of three million years for primordial Earth's chemical composition to settle. At the time, there was hardly any water, carbon compounds, or other ingredients necessary for life to emerge. Only a planetary collision that came later would have brought water to Earth, according to a new study by researchers from the Institute of Geological Sciences at the University of Bern. from Universe Today https://ift.tt/VE7IA26 via IFTTT

This sparkling scene of star birth was captured by the NASA/ESA/CSA James Webb Space Telescope. What appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being eaten away by the blistering winds and radiation of nearby, massive, infant stars. from Universe Today https://ift.tt/zqQcfbV via IFTTT

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). from Universe Today https://ift.tt/ei1Sl3k via IFTTT

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. from Universe Today https://ift.tt/plkVoSy via IFTTT

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. from Universe Today https://ift.tt/4ckSJZt via IFTTT
