About Camille M. Carlisle

Science Editor Camille M. Carlisle covers science news for Sky & Telescope. She specializes in black holes, galactic cosmology, and whatever she happens to be writing about at the time. She and Robert Naeye co-edited S&T's special issue Mars: Mysteries and Marvels of the Red Planet, published summer 2014.

The Quasar Main Sequence

A new diagram might link the diverse visible-light characteristics of quasars to two physical properties — essentially, their accretion rate and orientation. If the analysis holds up, it could point the way toward a long-sought unification.

Laniakea: Our Home Supercluster

Astronomers have mapped the cosmic watershed and discovered a massive supercluster that extends more than 500 million light-years and contains 100,000 large galaxies. The Milky Way sits on the edge of this humongous structure.

Direct Evidence of Big Bang Inflation

Researchers with an experiment based at the South Pole have discovered the long-sought "smoking gun" for inflation. The signal was hidden in polarization patterns in the cosmic microwave background and confirms physicists' audacious theory of how the Big Bang happened.

This composite of images from NASA’s Chandra X-ray Observatory and the Hubble Space Telescope reveals multiple images of a distant quasar. (Each of the four bright pink points around the ring is an image of the region around the same supermassive black hole.) Astronomers used Chandra and XMM-Newton data to measure how quickly the black hole is spinning.

Black Hole Spins Super Fast

X-ray observations and cosmic coincidence unveil the details of a distant supermassive black hole. The result could be a first step in expanding our understanding of how black holes have beefed themselves up over the last several billion years.
