  • Recent observations have uncovered a cloud of ionized gas falling into the supermassive black hole at the centre of our galaxy. Murray-Clay and Loeb present a model that may explain these observations, in which the cloud is produced from the proto-planetary disc around a low-mass star orbiting the black hole.

  • A population of extrasolar planets has been uncovered with minimum masses of 1.9–10 times the Earth's mass, called super-Earths, but atmospheric studies can be precluded by the distance and size of their stars. Here, observations of the transiting planet GJ 1214b are reported; it has a mass 6.55 times that of the Earth and a radius 2.68 times the Earth's radius. The star is small and only 13 parsecs away, permitting the study of the planetary atmosphere with current observatories.
