... GSAOI Home . ... Science . ... Deep imaging at J , H , and K is required to identify all stellar objects, brown dwarfs, and planetary mass objects in the central region of the Orion Nebula Cluster down to masses comparable to that of Jupiter. This is required to establish the initial mass function, i.e., the number of stars of each mass that have formed, in this region of intense massive star formation. ... The fields of the GSAOI detectors are shown as four green squares in each frame. ...

A very young star still deep within the dusty cocoon from which it formed is shown in . this image of IRAS 04016+2610. The star is visible as a bright reddish spot at the base . of a bowl-shaped nebula about 100 billion miles across at the widest point. The nebula . arises from dusty material falling onto a forming circumstellar disk, seen as a partial . dark band to the left of the star. The necklace of bright spots above the star is an image . artifact. Image: NASA

The Extragalactic ALFA Zone of Avoidance team is mapping the distribution of low-Galactic-latitude galaxies and large scale structures through detection of galaxies' 21-cm emission with ALFA. This Zone of Avoidance (ZOA) survey finds new HI galaxies which lie hidden behind the Milky Way, and also provides redshifts and other HI parameters for partially-obscured galaxies known at other wavelengths. ...
