These Hubble images show elliptical galaxies with dark, wispy dust lanes, the signature of a recent galaxy merger. The dust is the only relic of a smaller galaxy that was consumed by the larger elliptical galaxy. The X in the images marks the location of supernova explosions that are associated with the galaxies. Each supernova may have been gravitationally kicked out of its host galaxy by a pair of central supermassive black holes. When two galaxies merge, so do their supermassive black holes. Prof Foley suggests the supernovae were stars that were once part of double-star systems. These systems wandered too close to the binary black holes, which ejected them from their galaxies. Eventually, the stars in each system moved close enough together to trigger a supernova blast. These outcast supernovae are located at various distances from their home galaxies. SN 2000ds (left) is at least 12,000 light-years from its galaxy, NGC 2768; SN 2005cz (right) is at least 7,000 light-years from its galaxy, NGC 4589. NGC 2768 resides 75 million light-years from Earth, and NGC 4589 is 108 million light-years away. Image credit: NASA / ESA / R. Foley, University of Illinois.

This graphic illustrates how a star can magnify and brighten the light of a background star when it passes in front of the distant star. If the foreground star has planets, then the planets may also magnify the light of the background star, but for a much shorter period of time than their host star. Astronomers use this method, called gravitational microlensing, to identify planets. Image credit: NASA / ESA / A. Field, STScI.
