Astrophysicists measure precise rotation pattern of sun-like stars for the first...

IMAGE: Sun-like stars rotate differentially, with the equator rotating faster than the higher latitudes. The blue arrows in the figure represent rotation speed. Differential rotation is thought to be an essential... view more  Credit: MPI for Solar System Research/MarkGarlick.com Abu Dhabi, September 20, 2018: Sun-like stars rotate up to two and a half times faster at the equator than at higher latitudes, a finding by researchers…

New observations to understand the phase transition in quantum chromodynamics

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles…

Like our sun, other stars spin faster at the equator than...

Finally providing insights into the spin behavior of Sun-like stars outside our solar system, researchers now report that, much like the Sun, some other solar-type stars spin faster at their equators than at their poles. This keener insight into stellar rotation could inform numerous efforts in stellar astrophysics that rely on an understanding of the physical mechanisms acting in a star. Observations of sunspots on…

A material without limits

In its cubic crystal structure, cubic boron nitride, or c-BN, is one of the most remarkably-durable human-made materials ever invented, almost on par with natural and synthetic diamonds. It is widely used across…

NASA Updates Live Coverage of Japanese Cargo Launch, Delays Spacewalks

Delayed due to inclement weather, the Japan Aerospace Exploration Agency (JAXA) now is targeting 1:52 p.m. EDT Saturday, Sept. 22 (2:52 a.m. Sept. 23 in Japan), for the launch of its unpiloted H-II Transfer Vehicle-7 (HTV-7) cargo spacecraft.

Gaia detects a shake in the Milky Way

The existence of these substructures has been observed for the first…

Net successfully snares space debris

The RemoveDEBRIS satellite has successfully used its on-board net technology in orbit - the first demonstration in human history of active debris removal (ADR) technology. The spacecraft began the experimental phase of its mission on Sunday 16 September, when it used a net to capture a deployed target simulating a piece of space debris. RemoveDEBRIS was designed, built and manufactured by a consortium of leading…

‘Robotic skins’ turn everyday objects into robots

IMAGE: New 'Robotic Skins' technology developed by Yale researchers allows users to turn everyday objects into robots. view more  Credit: Yale University New Haven, Conn. - When you think of robotics, you likely think of something rigid, heavy, and built for a specific purpose. New "Robotic Skins" technology developed by Yale researchers flips that notion on its head, allowing users to animate the inanimate and turn…

Searching for errors in the quantum world

IMAGE: What does a physicist see when he examines a quantum object? The same as the observer of the physicist -- or just the opposite? view more  Credit: Picture: Philip Bürli/Visualeyes International There is likely no other scientific theory that is as well supported as quantum mechanics. For nearly 100 years now, it has repeatedly been confirmed with highly precise experiments, yet physicists still aren't entirely…

NASA Updates Preview Briefing for International Space Station Spacewalks, Live Coverage

Experts from NASA will preview two upcoming spacewalks outside the International Space Station to continue upgrades to the orbiting laboratory’s power system in a briefing at 2 p.m. EDT Thursday, Sept. 27, at the agency’s Johnson Space Center in Houston.
