NASA publishes images of unnoticed meteor explosion – Al-Arabiya

NASA on Friday published satellite photos of a powerful meteor which appeared just above the Bering Sea on December 18, but went unnoticed until months later. The explosion unleashed around 173 kilotons of energy, more than 10 times that of the atomic bomb blast over Hiroshima in World War II. Images captured minutes after the […]

Scientists find abundance of 500,000-year-old fossils in China – BGR

The thing about fossils is the older they are, the rarer they are. Earth doesn’t keep anything around forever, and the farther you go back in time the less likely you are to find evidence of the plants and animals that were alive then. So, when we’re talking about fossils of creatures that died over […]

Spacewalking astronauts swap out space station’s batteries – The Mainichi

(AP) — Changing batteries in orbit took some huffing and puffing and some intricate maneuvering by two spacewalkers Friday. But in the end, it went almost as smoothly as doing the chore back on Earth. NASA’s Anne McClain and Nick Hague took 6 hours and 39 minutes to replace three old nickel-hydrogen batteries […]

OSIRIS-REx Spacecraft Studies Asteroid Bennu Up Close – Space Ref

Press Release From: University of Arizona Posted: Friday, March 22, 2019 When NASA’s OSIRIS-REx spacecraft arrived at its destination, asteroid Bennu, on Dec. 3, it found a tiny world that in many respects looks like what the mission team had expected based on ground-based observations, but holds quite a few surprises, too. In a series […]

Optical tweezers combine with X-rays to enable analysis of crystals in liquids – Nanowerk

Mar 22, 2019 (Nanowerk News) Understanding how chemical reactions happen on tiny crystals in liquid solutions is central to a variety of fields, including materials synthesis and heterogeneous catalysis, but obtaining such an understanding requires that scientists observe reactions as they occur. By using coherent X-ray diffraction techniques, scientists can measure the exterior shape of […]

New Process Could Transform Seawater Into Hydrogen Fuel In Cost Efficient Way – Forbes

Researchers have demonstrated a new method for making hydrogen fuel directly from ocean water, skipping the costly water purification part of the process. By running an electrical current through water, it’s possible to separate it into oxygen and hydrogen, the latter of which can be used as a reliable, zero-emission source of fuel. Previously, a key part of the method […]
