Using infrared data from the Subaru Telescope in Hawaii, an international team of astronomers has imaged a giant planet around the bright star GJ 504. Several times the mass of Jupiter and similar in size, the new world, dubbed GJ 504b, is the lowest-mass planet ever detected around a star like the sun using direct imaging techniques.

Probing the location of a recent short-duration gamma-ray burst in near-infrared light, astronomers using the Hubble Space Telescope found the fading fireball produced in the aftermath of the blast. The afterglow reveals for the first time a new kind of stellar blast called a kilonova.

With the signing last week of a 'master agreement' for the Thirty Meter Telescope - destined to be the most advanced and powerful optical telescope in the world - the University of California and UCLA moved a step closer to peering deeper into the cosmos than ever before.

Astronomers have discovered a graveyard of comets. The researchers describe how some of these objects, inactive for millions of years, have returned to life leading them to name the group the 'Lazarus comets'.

On average, galaxies that no longer form stars are larger today than they were several billion years ago. However, this has nothing to do with individual galaxies merging with others, as was long thought to be the case, concludes ETH-Zurich professor Marcella Carollo after evaluating data from the Hubble Space Telescope.

A NASA technologist has developed a fully automated tool that gives mission planners a preliminary set of detailed directions for efficiently steering a spacecraft to hard-to-reach interplanetary destinations, such as Mercury, Jupiter, Saturn, and most comets and asteroids.

Using Cassini data, astronomers have determined that the amount of water vapor and ice erupting from Enceladus depends on tidal forces from Saturn - the same phenomenon that creates tides on Earth.

Read moreThis spring, humanity was shown its most detailed map of the early universe ever created. Generated by observations from the Planck spacecraft, the map revealed fluctuations in temperature in the relic radiation left over from the Big Bang - what we call the Cosmic Microwave Background (CMB). Recently, scientists on the Planck team announced finding certain large-scale features on the CMB sky that they cannot explain. One of them: a large cold spot, which corresponds to an anomalously large area of high density.

Using data from a NASA satellite, scientists have discovered a massive particle accelerator in the heart of one of the harshest regions of near-Earth space, a region of super-energetic, charged particles surrounding the globe and known as the Van Allen radiation belts.
