Proxima Centauri is our nearest stellar neighbor and is known to be a very active M dwarf #star.

Known to host a potentially #habitable #planet, the star #Proxima exhibits very active #flare activity in optical wavelengths.

Depending on the energy and frequency of these flares, nearby planets in the habitable zone might be rendered uninhabitable as the flares strip planetary atmospheres of necessary ingredients such as ozone and water.

Phys.org · Small star, mighty flares: ALMA shares new view of Proxima CentauriBy National Radio Astronomy Observatory

What happens when a newly formed #star captures material from a nearby cloud?

Gas, dust, and rocky materials swirl around recently formed #stars, creating a circumstellar disk that seeds the formation of #planets.

Recent observations of some of these disks reveal filamentary structures of material falling into the disk, feeding the planet-forming environment with new ingredients in a process known as “late-stage infall.”

AAS Nova · A Late-Stage Infall Renovation: Mapping the Circumstellar Disk of AB AurigaeWhat happens when a young star captures some extra gas and dust? New observations of a dusty disk reveals how a late-stage infall event may be influencing planet formation in AB Aurigae.

"Star" is such a fun pop song, and ARTMS seem to be enjoying themselves here.

Those familiar with LOONA will no doubt wipe away a tear as they think back to the original version, to which I will link in the second post on this thread for the benefit of those not around - or should I say "not in orbit"? - at the time of the original release.
