An international team of researchers has measured, with unprecedented accuracy, the gravitational redshift of the Sun, a change in frequency of the lines in the solar spectrum which is produced when the light escapes from the gravitational field of the Sun on its way to Earth.

A team of gravitational-wave scientists reveals that when two black holes collide and merge, the remnant black hole 'chirps' not once, but multiple times, emitting gravitational waves - intense ripples in the fabric space and time - that inform us about its shape.

Earth is not necessarily the best planet in the universe. Researchers have identified two dozen planets outside our solar system that may have conditions more suitable for life than our own. Some of these orbit stars that may be better than even our sun.

Now you see it, now you don't. Though stars explode at the rate of one per second in the vast universe, it's rare to get a time-lapse movie of one fading into obscurity. This disappearing act, in a galaxy 70 million light-years away, was captured by the Hubble Space Telescope as part of a program to measure the universe's expansion rate.

Communications in space demand the most sensitive receivers possible for maximum reach, while also requiring high bit-rate operations. A novel concept for laser-beam based communications uses an almost noiseless optical preamplifier in the receiver.

Geoscientists have now been able to prove that these diamonds formed in the early period of our solar system when minor planets collided together or with large asteroids. These new data disprove the theory that they originated deep inside planets.

Researchers have shaken up a once accepted timeline for cataclysmic events in the early solar system. It was once thought that this period had a relatively sudden onset, but a research team has found evidence that this bombardment period may have started much earlier, and decreased in intensity over time.

Computer simulations are showing astrophysicists how massive clumps of gas within galaxies scatter some stars from their orbits, eventually creating the smooth, exponential fade in the brightness of many galaxy disks.
