Graphene foam gets big and tough
more »
Graphene foam reinforced with carbon nanotubes can hold thousands of times its own weight and still bounce back to its full height. The material is thermally stable and highly conductive, making it suitable for batteries and other electrical applications.

Black-hole-powered jets forge fuel for star formation
more »
Astronomers have discovered a surprising connection between a supermassive black hole and the galaxy where it resides. Powerful radio jets from the black hole - which normally suppress star formation - are stimulating the production of cold gas in the galaxy's extended halo of hot gas. This newly identified supply of cold, dense gas could eventually fuel future star birth as well as feed the black hole itself.

NASA's OSIRIS-REx takes its first image of Jupiter
more »
This image was taken at 3:38 a.m. EST on Feb. 9, 2017, when the spacecraft was 75 million miles (120 million kilometers) from Earth and 419 million miles (675 million kilometers) from Jupiter. With an exposure time of two seconds, the image renders Jupiter overexposed, but allows for enhanced detection of stars in the background.

How disturbances interact with a dynamic space-time fabric: 'Field patterns' as a new mathematical object

The Calabash Nebula from Hubble
more »
Fast expanding gas clouds mark the end for a central star in the Calabash Nebula. The once-normal star has run out of nuclear fuel, causing the central regions to contract into a white dwarf. Some of the liberated energy causes the outer envelope of the star to expand. In this case, the result is a photogenic proto-planetary nebula. As the million-kilometer per hour gas rams into the surrounding interstellar gas, a supersonic shock front forms where ionized hydrogen and nitrogen glow blue. Thick gas and dust hide the dying central star. The Calabash Nebula, also known as the Rotten Egg Nebula and OH231.8+4.2, will likely develop into a full bipolar planetary nebula over the next 1000 years. The nebula, featured here, is about 1.4 light-years in extent and located about 5000 light-years away toward the constellation of Puppis.

The heart of a far-off star beats for its planet

For the first time, astronomers have observed a star pulsing in response to its orbiting planet. The star, which goes by the name HAT-P-2, is about 400 light years from Earth and is circled by a gas giant measuring eight times the mass of Jupiter -- one of the most massive exoplanets known today.

New delta Scuti: Rare pulsating star 7,000 light years away is one of only seven in Milky Way
more »
The newest delta Scuti (SKOO-tee) star in our night sky is so rare it's only one of seven identified by astronomers in the Milky Way. The star -- like our sun -- is in the throes of stellar evolution, to conclude as a dying ember in millions of years. Until then, the exceptional star pulsates brightly, expanding and contracting from heating and cooling of hydrogen burning at its core.
