Improved deformable mirrors could help scientists detect new sources of gravitational waves from deep in space. Researchers have developed a new type of deformable mirror that could increase the sensitivity of ground-based gravitational wave detectors such as the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO)...

Astronomers have captured new, detailed maps of three nearby interstellar gas clouds containing regions of ongoing high-mass star formation. The results of this survey, called the Star Formation Project, will help improve our understanding of the star formation process.

We know that stars such as the Sun are born from interstellar gas clouds. These interstellar gas clouds are difficult to observe in visible light, but emit strong radio wavelength, which can be observed by the Nobeyama 45-m Radio Telescope in Japan...

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found striking orbital geometries in protoplanetary disks around binary stars. While disks orbiting the most compact binary star systems share very nearly the same plane, disks encircling wide binaries have orbital planes that are severely tilted. These systems can teach us about planet formation in complex environments.

In the last two decades, thousands of planets have been found orbiting stars other than our Sun. Some of these planets orbit two stars, just like Luke Skywalker’s home Tatooine...

A comet called Atlas is currently heading toward the sun, and it just might put on a really good show in a couple of months. Discovered last December by the Asteroid Terrestrial-impact Last Alert system in Hawaii (thus the name ATLAS for the comet), the comet has been growing much brighter than experts had predicted. If it manages to hold its shape as it moves nearer to the sun, it could grow brighter than Venus.

Shortly after its discovery, ATLAS began growing brighter than expected—a lot brighter. So bright that it can now be seen by amateur astronomers with binoculars. It is expected to reach its peak brightness at the end of May...
