Modest-mass galaxy hosts oversized black hole: an evolutionary missing link?

24 September 2015 Astronomy Now

The central supermassive black hole of a recently discovered galaxy called SAGE0536AGN is far larger than should be possible, according to current theories of galactic evolution. The galaxy was found by accident with NASA’s Spitzer space telescope and is thought to be at least 9 billion years old. Time will tell whether SAGE0536AGN really is an oddball, or simply the first in a new class of galaxies.

UK work-experience schoolboy discovers a new planet

Tom Wagg, now aged 17, discovered a new planet orbiting a star 1000 light-years away in the constellation of Hydra. He was doing work-experience at Keele University two years ago when he spotted the body by finding a tiny dip in the light of its parent star as the planet passed in front of it.

Supermassive black hole blasts star-making gas from galaxy’s core

26 March 2015 Astronomy Now

Many galaxies blast huge, wide-angled flows of material outward from their centres, pushing to their outer edges enough dust and gas each year that otherwise would have formed more than a thousand stars the size of our Sun. A team led by University of Maryland scientists has found the driving force behind these massive molecular outflows.
