De ring van SDP.81
ALMA’s Long Baseline Campaign heeft een spectaculair detailrijke opname opgeleverd van een ver sterrenstelsel. De foto toont een ‘gravitationeel vergroot’ beeld van de stervormingsgebieden in het stelsel – grote soortgenoten van de bekende Orionnevel. Nooit eerder zijn zulke stellaire kraamkamers in zo’n ver sterrenstelsel zo duidelijk in beeld gebracht – de nieuwe waarnemingen zijn vele malen detailrijker dan eerdere opnamen, zoals die van de Hubble-ruimtetelescoop van NASA en ESA. Afgebeeld is het ‘gravitationeel gelenste’ sterrenstelsel SDP.81, dat zich als een vrijwel complete Einsteinring vertoont.
