Fast radio bursts (FRBs) are brief spurts of radio emission

Fast radio bursts (FRBs) are brief spurts of radio emission, lasting just one-thousandth of a second, whose origins are mysterious. Fewer than two dozen have been identified in the past decade using giant radio telescopes such as the 1,000-foot dish in Arecibo, Puerto Rico. Of those, only one has been pinpointed to originate from a […]


The research refute hypothesis on what caused abrupt climate change thousands of years ago

Two new studies in the Journal of Quaternary Science refute the hypothesis that one or more comets/bolides struck North America nearly 12,900 years ago triggering rapid climate change and the start of the Younger Dryas period. Before the Younger Dryas, the climate had gradually warmed from glacial conditions to near modern temperatures, and the massive […]

New instrument could search for signatures of life on Mars

A sensing technique that the U.S. military currently uses to remotely monitor the air to detect potentially life-threatening chemicals, toxins, and pathogens has inspired a new instrument that could “sniff” for life on Mars and other targets in the solar system — the Bio-Indicator Lidar Instrument, or BILI. Branimir Blagojevic, a NASA technologist at the […]

New, space-based view of human-made carbon dioxide

Scientists have produced the first global maps of human emissions of carbon dioxide ever made solely from satellite observations of the greenhouse gas. The maps, based on data from NASA’s Orbiting Carbon Observatory-2 (OCO-2) satellite and generated with a new data-processing technique, agree well with inventories of known carbon dioxide emissions. No satellite before OCO-2 […]

Close galactic encounter leaves ‘nearly naked’ supermassive black hole

Astronomers using the super-sharp radio vision of the National Science Foundation’s Very Long Baseline Array (VLBA) have found the shredded remains of a galaxy that passed through a larger galaxy, leaving only the smaller galaxy’s nearly-naked supermassive black hole to emerge and speed away at more than 2,000 miles per second. The galaxies are part […]

NASA’s NavCube could support an X-ray communications demonstration in space

Two proven technologies have been combined to create a promising new technology that could meet future navigational challenges in deep space. It also may help demonstrate — for the first time — X-ray communications in space, a capability that would allow the transmission of gigabits per second throughout the solar system. The new technology, called […]

Novel analysis technique helps solve Beagle 2 mystery

Scientists in Leicester have moved one step closer to understanding exactly what happened to the ill-fated Mars Lander Beagle 2, thanks to an innovative research technique. The probe was discovered on the Red Planet in November 2014 but uncertainty surrounded what had caused its failure to communicate with Earth. Now, a collaboration between De Montfort […]

Solar physicist finds new way to study the inner workings of the sun

In 2009, applied physicist Peter Sturrock was visiting the National Solar Observatory in Tucson, Arizona, when the deputy director of the observatory told him he should read a controversial article about radioactive decay. Although the subject was outside Sturrock’s field, it inspired a thought so intriguing that the next day he phoned the author of […]
