Recently Launched Observatory Identifies Two Unknown and Important Black Holes [Nature]

NASA’s NuSTAR (Nuclear Spectroscopic Array) X-ray observatory was launched in June and already is providing important findings. My article in Nature, NuSTAR spies black holes in galactic web, details the finding of two possible intermediate-mass black holes in the nearby galaxy IC 342:

The image below shows the galaxy IC 342, with the two black holes displayed in false color magenta. For more information about the new observatory and the black holes, read the rest of the article at Nature.

Finding Record-Old Galaxies at the Limits of Hubble Space Telescope [Nature]

Recent infrared images taken from the Hubble Space Telescope’s Wide Field Camera 3 are the deepest taken of the Universe, and they reveal several galaxies, including one that is the most distant object we’ve ever found. This galaxy is 13.29 billion light years (4.1 billion parsecs) from Earth and were first visible when the Universe was only 450 million years old (only 4 percent of what it is now). From my recent article in Nature, Galaxy found at record-breaking distance:
