Astronomers using NASA’s Chandra X-ray Observatory are searching for signs of a recoiling black hole in the core of A2261-BCG, the most massive and brightest galaxy in the giant galaxy cluster Abell 2261. This image of Abell 2261, a galaxy cluster located 3 billion light-years away, contain X-ray data from Chandra showing hot gas pervading the cluster as well as optical data from Hubble and the Subaru Telescope that show galaxies in the cluster and in the background. A2261-BCG (center), also known as 2MASX J17222717+3207571, is the most massive and brightest galaxy in the cluster. Image cre...

Ramin Skibba, Contributor (Inside Science) -- For decades, even before the iconic Hubble telescope took flight, astronomers have been launching spacecraft into orbit in the hopes of avoiding atmospheric effects that blur images taken by telescopes on Earth. But to catch clear signals of some cosmic objects, even those orbits aren’t high enough. A group of astronomers now make the case for assembling and planting telescopes on the moon. In a series of newly published papers, they argue that our lunar neighbor, especially its far side, makes an excellent place for telescopes in the radio and ...

That might be the last news you expected to hear toward the darkening end of a dark year. But that is what a band of astronomers has discovered, using cameras on the New Horizons spacecraft that once visited Pluto to measure the darkness of interplanetary space. “There’s something out there unknown,” said Tod Lauer, of the National Optical-Infrared Astronomy Research Laboratory in Tucson, Arizona. “The universe is not completely dark, and we don’t y...
