The observatories are also releasing their first catalog of gravitational-wave events. The LIGO and Virgo collaborations have now confidently detected gravitational waves from a total of 10 stellar-mass binary black hole mergers and one merger of neutron stars, which are the dense, spherical remains of stellar explosions. Six of the black hole merger events had been reported before, while four are newly announced.

From September 12, 2015, to January 19, 2016, during the first LIGO observing run since undergoing upgrades in a program called Advanced LIGO, gravitational waves from 3 binary black hole mergers were detected...

Force Push is a novel VR technique that allows users to move objects with unprecedented nuance.

The VR interface responds to device-free nuanced hand movements. Force Push provides a more physical, nuanced experience than traditional hand controllers allow in VR. It responds to the speed and magnitude of hand gestures to accelerate or decelerate objects in a way that users can understand intuitively.

Fans of the Star Wars franchise will have to wait more than a year from now to get their fix of Jedi-laden telekinetic spectacles on the big screen. The as-of-yet-to-be-titled Episode IX, the last installment of the space saga as was envisioned in 1977, won’t be released until December 2019...

An international team of astronomers using a combination of ground and space based telescopes have reported more than 100 extrasolar planets (here after, exoplanets) in only three months. These planets are quite diverse and expected to play a large role in developing the research field of exoplanets and life in the Universe.

Exoplanets, planets that revolve around stars other than the Sun, have been actively researched in recent years. One of the reasons is the success of the Kepler Space Telescope, which launched in 2009 to search for exoplanets...

The three gaseous components form the long-theorized ‘donut’ structure: (1) a disk of infalling dense cold molecular gas, (2) outflowing hot atomic gas, and (3) gas returning to the disk.

Based on computer simulations and new observations from the Atacama Large Millimeter/submillimeter Array (ALMA), researchers have found that the rings of gas surrounding active supermassive black holes are not simple donut shapes. Instead, gas expelled from the center interacts with infalling gas to create a dynamic circulation pattern, similar to a water fountain in a city park.

Most galaxies host a supermassive black hole, millions or billions of times as heavy as the Sun, in their centers. Some of these black holes swallow material quite actively...
