Is the universe a hologram?
Describing the universe requires fewer dimensions than we might think; new calculations show that this may not just be a mathematical trick, but a fundamental feature of space itself.

Electric Solar Wind Sail could make bidirectional manned Mars flights economically feasible
The E-sail is a novel propellantless technology that was invented in Finland in 2006. The E-sail utilises long, charged tethers to convert natural solar wind momentum flux into spacecraft thrust.

Astronomers find runaway galaxies
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.

Mysterious dust jet from Comet 67P/Churyumov-Gerasimenko
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 find new details about star formation in ancient galaxy protoclusters
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.

Black hole hunters tackle a cosmic conundrum
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.

Pulsing light may indicate supermassive black hole merger
As 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.
