We know of about two dozen runaway stars, and have even found one runaway star cluster escaping its galaxy forever. Now, astronomers have spotted 11 runaway galaxies that have been flung out of their homes to wander the void of intergalactic space.

Comets eject gas and dust into space. Primarily, this takes place on the areas of the comet's surface exposed to direct sunlight. In mid-March, from a distance of 75 kilometres, the Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS) on board the Rosetta orbiter acquired images of an extraordinary phenomenon occurring on Comet 67P/Churyumov-Gerasimenko. A new dust jet - its origins currently unknown - was suddenly released from the shadowed side.

Astronomers are tracking velocity structures and gaseous metallicities in galaxies in two protoclusters located in the direction of the constellation Serpens. The clusters appear as they would have looked 11 billion years ago, and the team concluded that they are in the process of cluster formation that has led to present-day galaxy clusters.

Astrophysicists have not only proven that a supermassive black hole exists in a place where it isn't supposed to be, but in doing so have opened a new door to what things were like in the early universe.

Read moreAs two galaxies enter the final stages of merging, scientists have theorized that the galaxies' supermassive black holes will form a 'binary', or two black holes in such close orbit they are gravitationally bound to one another. In a new study, astronomers present direct evidence of a pulsing quasar, which may substantiate the existence of black hole binaries.

Complex organic molecules such as formamide, from which sugars, amino acids and even nucleic acids essential for life can be made, already appear in the regions where stars similar to our Sun are born. Astrophysicists have detected this biomolecule in five protostellar clouds and propose that it forms on tiny dust grains.
