Read moreAstronomers have discovered thousands of exoplanets in our galaxy, the Milky Way, using the Kepler satellite and many of them have multiple planets orbiting the host star. By analysing these planetary systems, researchers have calculated the probability for the number of stars in the Milky Way that might have planets in the habitable zone. The calculations show that billions of the stars in the Milky Way will have one to three planets in the habitable zone, where there is the potential for liquid water and where life could exist.

Read moreSulfide chondrules, a new type of building blocks discovered in meteorites left over from the solar system's infancy, provide evidence for a previously unknown region in the protoplanetary disk that gave rise to the planets including Earth.

Read moreFollowing a successful launch at 10:44 p.m. EDT Thursday, NASA's four Magnetospheric Multiscale (MMS) spacecraft are positioned in Earth's orbit to begin the first space mission dedicated to the study of a phenomenon called magnetic reconnection. This process is thought to be the catalyst for some of the most powerful explosions in our solar system.

Read moreA team of astronomers have identified nine new dwarf satellites orbiting the Milky Way, the largest number ever discovered at once. The findings, from newly-released imaging data taken from the Dark Energy Survey, may help unravel the mysteries behind dark matter, the invisible substance holding galaxies together.

Read moreA team of astronomers discovered an unusual phenomenon in the centre of the Milky Way: They detected about 20 rotating dust and gas discs in each cluster hosting exceptionally large and hot stars. The existence of these discs in the presence of the destructive UV radiation field of their massive neighbours came as a surprise.
