... These Frontier Fields will combine the power of HST with the natural gravitational telescopes of high-magnification clusters of galaxies. ... We are soliciting gravitational lensing maps for the last four Hubble Frontier Fields clusters (MACSJ0717.5+3745, MACSJ1149.5+2223, AbellS1063, and Abell 370) based upon the exceptionally deep HST FF imaging and other new ancillary data. ... For the full set of proposal instructions and requirements, see the FY16 Frontier Fields Lensing Map Call for Proposals....

Large sunspots were occasionally seen far in the past without any instruments, when the sun was dimmed by thick haze, but not much was remembered of those observations. ... Sunspot Cycle (1850 - 1975) . One who was greatly influenced by Schwabe's discovery was an English gentleman of independent means, Richard Christopher Carrington , who devoted himself to the study of sunspots. ... Carrington had seen a flare, of the rare variety that is visible in white light (only about 50 are known). ...

home publications > mercury . ... Astronomy Beat . ... Nearly four centuries ago, Galileo's simple observations of Earth's planetary sibling, Venus, buoyed the proponents of a Copernican universe. ... The Italian astronomer had settled into a new house in Florence and had begun to observe Venus, which in November 1610 would have appeared as an evening star, bright in the western sky after dusk. ... From these two observations, Galileo inferred that Venus must orbit closer to the Sun than does Earth. ...

The Discovery of the Galilean Satellites . ... Probably the most significent contribution that Galileo Galilei made to science was the discovery of the four satellites around Jupiter that are now named in his honor. Galileo first observed the moons of Jupiter on January 7, 1610 through a homemade telescope. He originally thought he saw three stars near Jupiter, strung out in a line through the planet. ...

The discovery of supernova 1995V in NGC 1087 is the second discovery to be made this year with the larger telescope. ... After this, they took two CCD pictures of NGC 1087 from which the magnitude of the supernova could be calculated in relation to a nearby measured star, and the offsets of the supernova could also be measured. ...

Plans are under way to create a new way of performing non-interactive observations which will be called auto-observing . ... Non-interactive observing with CIMA has for a long time been available with the use of CIMA command files. Contrary to normal command file observing which requires a command file with a set of commands to be executed sequentially, auto-observing will use a list of sources and a list of instructions on how to observe each of the sources. ...
