An artist’s rendition of the Akira (right) and Tetsuo (left) galaxies in action. Akira’s gravity pulls Tetsuo’s gas into its central supermassive black hole, fueling winds that have the power to heat Akira’s gas. Because of the action of the black hole winds, Tetsuo’s donated gas is rendered inert, preventing a new cycle of star formation in the Akira galaxy. Image credit: Kavli IPMU.

This Hubble Space Telescope image of Comet 252P/LINEAR was photographed at 20:56 GMT on April 4, when the comet was 8.6 million miles from Earth. The visit was one of the closest encounters between this comet and our planet. This image was originally black and white and recorded only overall brightness. These brightness values were translated into a range of bluish hues. Such color ‘maps’ can be useful in helping to distinguish subtly varying brightness in an image. Image credit: NASA / ESA / J.-Y.
