Accretion streamers feed young protoplanetary disks

Researchers from IRAM and IPAG have announced new results shedding light on how young planetary systems form. Using the NOEMA interferometer together with the IRAM 30-meter telescope, the team studied how accretion streamers (flows of interstellar material) feed protoplanetary disks around newly born stars. Observations of the protostar L1489 IRS reveal that these streamers can [...]

Nature article – Threats to Astronomy

A recent editorial in Nature Astronomy warns that astronomy is facing growing pressures from both technological developments in space and policy decisions on Earth. The article highlights satellite megaconstellations as a major “threat from above,” noting that their brightness and radio emissions are increasingly contaminating astronomical observations—even for space-based telescopes. Planned large-scale expansions could worsen [...]
