The improbable case of the high-energy novae: NASA’s Fermi space telescope detects new gamma ray sources

Novae typically originate in binary systems containing Sun-like stars, as shown in this artist’s rendering. NASA’s Fermi Space Telescope discovered that a nova in a system like this likely produces gamma rays (magenta) through collisions among multiple shock waves in the rapidly expanding shell of debris.

Electrons in magnetic field reveal surprises

Beam out: elongated "Landau" states - Instead of rotating uniformly at a particular frequency, an international team of researchers has found that electrons in a magnetic field are capable of rotating at three different frequencies, depending on their quantum properties.

UT research uncovers forces that hold gravity defying near earth asteroid together

Asteroid 1950 DA. “Following the February 2013 asteroid impact in Chelyabinsk, Russia, there is renewed interest in figuring out how to deal with the potential hazard of an asteroid impact,” said Rozitis. “Understanding what holds these asteroids together can inform strategies to guard against future impacts.” (Credit: NASA)

‘Monster’ quasars got that way by gorging on gas

"The puzzle has been how these 'seed' black holes grew into the monsters that we now see within the time available, a few billion years at best," says Priyamvada Natarajan, who proposes that early quasars took in a "super boost," feasting from large reservoirs of gas that were part of early star clusters.

NASA sleep promoting light bulb hopes to send you to snoozeland, ASAP!

Lighting Science created special lightbulbs for the ISS. There are daylight bulbs with bluer light to encourage energy and activity during what would be daytime hours, and then there are lightbulbs that dial back on the blue to boost astronauts’ production of melatonin for a good night’s sleep.
