... STScI-PF95-18 RELEASE DATE: March 31, 1995 HUBBLE TRACKS JUPITER STORMS NASA's Hubble Space Telescope is following dramatic and rapid changes in Jupiter's turbulent atmosphere that will be critical for targeting observations made by the Galileo space probe when it arrives at the giant planet later this year. This Hubble image provides a detailed look at a unique cluster of three white oval-shaped storms that lie southwest (below and to the left) of Jupiter's Great Red Spot. ...

... 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. ...

The File System . ... Files are identified to the system using a unique identifier called the file specification , which can include disk and directory names as well as node names for accessing files across the network. On VMS systems, file names are usually thought of as having three parts *1 : the filename , the file type , and the version number . ... The full file specification, with node name, device, directory, file name, file type, and version being specified is shown in Figure 3.1 . ...

... The idea of an ALFA Virgo Survey is very excited. We should go for full coverage of the Virgo cluster, that is 800 square degrees. ... To interpret and understand the results of such a survey will require a lot of complimentary data. In Milano, we have developed the Galaxy On Line Database Milano Network or GOLDMiNe . ... This site provides on line selection of multiwavelength data for galaxies in both the Virgo cluster and the Coma supercluster. ...

... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...
