... 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....

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... Most people that are interested in supernovae use whatever telescopes they can get access to, but researchers at certain colleges and universities are able to access specialized telescopes like NASA?s Chandra X-ray Observatory . It?s a telescope that orbits the Earth and that has a specialized purpose of being able to observe X-ray emissions from supernovae, clustered galaxies and the materials around black holes. ... super@supernovae.net . ...

However others are less pessimistic and it has even been claimed that the mysterious ?Wow! signal? received in 1977 originated from the direction M55.б  Sadly, this still unexplained pulse of radio energy originated from a location rather to the northwest of M55 so I doubt if the source was this cluster (if indeed the signal was genuinely of extraterrestrial origin). ...

This video shows the first ever map of the weather on the surface of the nearest brown dwarf to Earth. An international team has used ESO's Very Large Telescope to create a chart of the dark and light features on WISE J104915.57-531906.1B, which is informally known as Luhman 16B and is one of two recently discovered brown dwarfs forming a pair only six light-years from the Sun. ...

... STScI-PRC98-21 A BRIGHT RING OF STAR BIRTH AROUND A GALAXY'S CORE An image from NASA's Hubble Space Telescope reveals clusters of infant stars that formed in a ring around the core of the barred-spiral galaxy NGC 4314. ... This close-up view by Hubble also shows other interesting details in the galaxy's core: dust lanes, a smaller bar of stars, dust and gas embedded in the stellar ring, and an extra pair of spiral arms packed with young stars. ... However, they are older than those in the ring. ...

An international group of astronomers, including Dr Simon Jeffery of the Armagh Observatory, has used the Hubble Space Telescope to verify the origin of a very unusual and rare type of star. The group's studies confirm that the so-called "extreme helium stars" are formed by the merger of two white dwarf stars. ... One, dubbed the final-flash (FF) model, suggests an outer helium layer of a cooling white dwarf ignites, producing an extra thermal pulse that balloons the star into a giant. ...
