NASA's Johnson Space Center, White Sands Earn EPA 'Green' Honors

The U.S. Environmental Protection Agency (EPA) has recognized NASA's White Sands Test Facility in Las Cruces, N.M., and Johnson Space Center in Houston as Federal Green Challenge National Award winners.

Update: The Battle Over Who Gets to Name Planets

Last Thursday, a team of scientists working with NASA's Kepler space telescope described three intriguing new planets circling distant stars. Three of them are just slightly larger than Earth and orbit in the "habitable zone" where temperatures could be right for liquid water and for life. The names of these amazing worlds? Kepler 62f, Kepler 62e, and Kepler 69c. Not to be confused with other much-celebrated recent discoveries like Kepler 64b, Kepler 22b, or Gliese 581g.

NASA Partner Orbital Sciences Test Launches Antares Rocket

NASA commercial space partner Orbital Sciences Corporation Sunday launched its Antares rocket at 5 p.m. EDT from the new Mid-Atlantic Regional Spaceport Pad-0A at the agency's Wallops Flight Facility in Virginia.

Watch This: Ringing out a Wet Washcloth in Zero Gravity

What happens when you take a soaking wet washcloth in zero gravity and try to squeeze out all the water? Probably not what you'd expect. Hint: it has to do with surface tension. And it's totally trippy.

To find out for sure, Canadian astronaut Chris Hadfield conducts an experiment aboard the International Space Station. The process of getting the washcloth wet is entertaining enough, but the actual outcome is a bizarro sight to see.

Freedom of assembly: Scientists see nanoparticles form larger structures in real time

Scientists have, for the first time, captured movies of nanoparticle self-assembly, giving researchers a new glimpse of an unusual material property.

Wind turbines operate under great turbulence, with consequences for grid stability

(Phys.org) —While previous research has shown that wind turbulence causes the power output of wind turbines to be intermittent, a new study has found that wind turbulence may have an even greater impact on power output than previously thought. The researchers modeled the conversion of wind speed to power output using data from a rural wind farm. The results showed that the intermittent properties of wind persist on the scale of an entire wind farm, and that wind turbines do not only transfer wind intermittency to the grid, but also increase it.

Technique unlocks design principles of quantum biology

Researchers have created a synthetic compound that mimics the complex quantum dynamics observed in photosynthesis and may enable fundamentally new routes to creating solar-energy technologies.

NASA's Hubble Sees a Horsehead of a Different Color

Astronomers have used NASA's Hubble Space Telescope to photograph the iconic Horsehead Nebula in a new, infrared light to mark the 23rd anniversary of the famous observatory's launch aboard the space shuttle Discovery on April 24, 1990.

Earth Day Media Briefing With NASA Deputy Administrator Garver

Journalists are invited to attend an Earth Day visit by NASA Deputy Administrator Lori Garver to the agency's Goddard Space Flight Center in Greenbelt, Md., from 10 - 11:15 a.m. EDT on Monday, April 22.

Potentially Habitable Exoplanets Found Orbiting Nearby Star

Exoplanets have found a permanent place in the public imagination, probably because of the possibility of finding an Earth twin: a planet where life as we know it (either extraterrestrial or, eventually, our own) could survive. While we’re not there, yet, a NASA press conference today suggests we’ve come closer to this goal: the first known planets that could plausibly support life.

A nearby star named Kepler-62 turns out to harbor five worlds, two of which are the smallest exoplanets kno
