Phaethon confirmed as rock comet by STEREO vision

The Sun-grazing asteroid, Phaethon, has betrayed its true nature by showing a comet-like tail of dust particles blown backwards by radiation pressure from the Sun. Unlike a comet, however, Phaethon's tail doesn't arise through ...

Inflatable antennae could give CubeSats greater reach

The future of satellite technology is getting small—about the size of a shoebox, to be exact. These so-called "CubeSats," and other small satellites, are making space exploration cheaper and more accessible: The minuscule ...

More sustainable gas turbines thanks to ut research

The new generation of gas turbines is more reliable, produces less harmful emissions and generates less vibrations and pressure fluctuations. Thanks to the European Limousine Project, in which six different universities (18 ...

Portrait Earth: Wave at Saturn and Cassini July 19

Smile and say, "Cosmic cheese!" From 898 million miles away, NASA's Cassini-Huygens spacecraft will snap a portrait of Earth July 19 from between Saturn's rings as North America and the Atlantic Ocean repose on the sunny ...

A new state of Venus's ionosphere

Observations from NASA's Pioneer Venus orbiter, which reached Venus in 1978, suggested that Venus's ionosphere had two states: a magnetized state with a large- scale horizontal magnetic field and an unmagnetized state with ...

Temperatures measured at Gale Crater higher than expected

(Phys.org)—Preliminary weather reports from the Curiosity's Remote Environment Monitoring Station (REMS) are showing some surprisingly mild temperatures during the day. Average daytime air temperatures have reached a peak ...

Solar storms can destabilize power grids at midlatitudes

The Sun is capable of disrupting electrical systems on Earth in a variety of ways, from solar flares and coronal mass ejections to proton storms. Typically, it is only objects far above the Earth's surface, or systems at ...

'Nano machine shop' shapes nanowires, ultrathin films

(Phys.org)—A new "nano machine shop" that shapes nanowires and ultrathin films could represent a future manufacturing method for tiny structures with potentially revolutionary properties.

Arctic ice melt sets stage for cold weather

(Phys.org) -- The dramatic melt-off of Arctic sea ice due to climate change is hitting closer to home than millions of Americans might think. That's because melting Arctic sea ice can trigger a domino effect leading to increased ...
