Potential Mid-size Black Hole Found

Scientists have found what seems to be an intermediate-mass black hole in a spiral galaxy 100 million light-years away. If its size is confirmed, it could provide much-needed insight into black hole evolution.

Monster Black Hole in Early Universe

Astronomers have discovered one of the brightest quasars in the early universe. The source, SDSS J010013.02+280225.8 (hereafter J0100+2802), is powered by a supermassive black hole at a redshift of 6.3, meaning that its light left it 12.8 billion years ago.

Solar and Lunar Eclipses in 2015

Two total lunar eclipses occur this year, on April 4th and September 27−28. Meanwhile, a total solar eclipse in March sweeps across remote Arctic waters on March 20th, and a partial event on September 13th is likewise poorly placed for observing. Any list of nature's grandest spectacles would certainly include…
