It might be easier than previously thought for a planet to overheat into the scorchingly uninhabitable "runaway greenhouse" stage, according to new research by astronomers at the University of Washington and the University of Victoria published July 28 in the journal Nature Geoscience.

In the runaway greenhouse stage, a planet absorbs more solar energy than it can give off to retain equilibrium. As a result, the world overheats, boiling its oceans and filling its atmosphere with steam, which leaves the planet glowing-hot and forever uninhabitable, as Venus is now.

July 30, 2013, Boston, Mass. -- Sun-drenched rooms make for happy residents, but large glass windows also bring higher air-conditioning bills. Now a bioinspired microfluidic circulatory system for windows developed by researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University could save energy and cut cooling costs dramatically -- while letting in just as much sunlight.

Just as remotely-operated vehicles help humans explore the depths of the ocean from above, NASA has begun studying how a similar approach may one day help astronauts explore other worlds. On June 17 and July 26, NASA tested the Surface Telerobotics exploration concept, in which an astronaut in an orbiting spacecraft remotely operates a robot on a planetary surface. In the future, astronauts orbiting other planetary bodies, such as Mars, asteroids or the moon, could use this approach to perform work on the surface using robotic avatars.

Astronomers have found a new way of measuring the spin in supermassive black holes, which could lead to better understanding about how they drive the growth of galaxies.

The scientists at Durham University, UK, observed a black hole - with mass 10 million times that of our Sun - at the centre of a spiral galaxy 500 million light years from Earth while it was feeding on the surrounding disc of material that fuels its growth and powers its activity.

The GOES-R Magnetometer Engineering Development Unit made an important development in the construction of the spacecraft recently after completing a successful boom deployment test at an ATK facility in Goleta, Calif.

The Geostationary Operational Environmental Satellite – R Series advanced spacecraft and instrument technology will result in more timely and accurate weather forecasts. It will improve support for the detection and observations of meteorological phenomena and directly affect public safety, protection of property, and ultimately, economic health and development.

NASA and NOAA satellites continue to keep a close eye on the remnants of Tropical Storm Dorian as they make their way through the eastern Caribbean Sea.

On Saturday, July 27 at 11 a.m. EDT, Dorian was still a tropical storm, but that didn't last. Dorian was near 18.5N and 52.1W, about 720 miles (1,160 km) east of the Northern Leeward Islands. Dorian's maximum sustained winds were near 40 mph (65 kph) and it was moving to the west at 23 mph (37 kph).

Tropical Storm Flossie is expected to bring a lot of moisture to the leeward side of the Hawaiian Islands where the Kona coffee crops are located. That moisture will then be pushed up the mountainous terrain (orographic lift), which will go over the mountainous areas and rain on the windward side.

Flossie will be moving in the big island during the morning (local time) today, July 29.

Washington, D.C.— Hydrogen is deceptively simple. It has only a single electron per atom, but it powers the sun and forms the majority of the observed universe. As such, it is naturally exposed to the entire range of pressures and temperatures available in the whole cosmos. But researchers are still struggling to understand even basic aspects of its various forms under high-pressure conditions.

A team of researchers has devised a way to measure the internal properties of stars—a method that offers more accurate assessments of their orbiting planets.

The research, which appears in Proceedings of the National Academy of Sciences, was conducted by a multi-national team of scientists, including physicists at New York University, Princeton University, and the Max Planck Institute for Solar System Research.

For the first time since exoplanets, or planets around stars other than the sun, were discovered almost 20 years ago, X-ray observations have detected an exoplanet passing in front of its parent star.

An advantageous alignment of a planet and its parent star in the system HD 189733, which is 63 light-years from Earth, enabled NASA's Chandra X-ray Observatory and the European Space Agency's XMM Newton Observatory to observe a dip in X-ray intensity as the planet transited the star.

Nearly doubling the efficiency of a breakthrough photovoltaic cell they created last year, UCLA researchers have developed a two-layer, see-through solar film that could be placed on windows, sunroofs, smartphone displays and other surfaces to harvest energy from the sun.

WASHINGTON, July 29, 2013 — After six years of anticipation, that rock star of plants — a rainforest giant known as the corpse flower for its putrid odor — has bloomed here, and is the subject of a new video by the American Chemical Society (ACS), the world's largest scientific society.

Tree ring records indicate that in the years to 774-775, atmospheric carbon-14 levels increased substantially.

NASA's Aqua satellite captured an image of smoke from northern Oregon's Sunnyside Turnoff Fire on July 25 as the satellite passed overhead in space.

The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies aboard Aqua captured an image of the smoke and heat from the Sunnyside Turnoff Fire on July 25 at 21:10 UTC (5:10 p.m. EDT/2:10 p.m. PDT). MODIS has the ability to detect hot spots or fires and they appear red in the image.

The Expedition 36 crew completed packing the Materials International Space Station Experiment-8 (MISSE-8) Payload Experiment Container (PEC) and Optical Reflector Materials Experiment-III (ORMatE-III) after it was retrieved during the spacewalk. The MISSE-8 samples have been in orbit for a little over two years and the PEC and ORMatE are manifested for return to Earth on SpaceX 3.
