Some parts of the planet are approaching the limits of their ability to adapt to climate change, scientists warned yesterday ahead of a major U.N. report being released later this month. Extreme drought and heat could prevent trees from absorbing carbon dioxide, thrusting some ecosystems past the point from which they can recover, the researchers … Read more
Jupiter has finally been observed spitting out X-rays in high-energy wavelengths. Emanating from the giant planet’s permanent auroras, and detected by NASA’s space-based X-ray telescope NuSTAR, the emissions are the most energetic light seen coming from any planet in the Solar System (aside from Earth). The detection could shed light on the most powerful … Read more
Pieces of rock from the asteroid Ryugu splashed down on Earth in 2020. Now, scientists studying the samples are revealing the asteroid’s true nature. Ryugu is a near-Earth asteroid that Japan visited with its Hayabusa2 spacecraft. The craft launched in 2014, arrived at the space rock in 2018 and in December 2020 dropped off a … Read more
What appears to be a teeny tiny alien world has just been found orbiting the Solar System’s closest stellar neighbor. The exoplanet candidate, named Proxima d, orbits a star named Proxima Centauri: a small, dim red dwarf star just 4.2 light-years from the Sun. Amazingly, the exoplanet is just a quarter of the mass … Read more
Recycling rare earth elements from the ash left over from coal burning is cheaper, easier and more environmentally friendly than digging them out of mines Environment 9 February 2022 By Alice Klein A microscope image of tiny glass spheres in coal fly ash that contain rare earth elements Rice University Rare earth elements that are … Read more
New images recorded by NASA’s Parker Solar Probe have revealed the red-hot glow of Venus‘s surface radiating through its shroud of toxic clouds – a finding that could help us better understand the minerals making up this rocky and mysterious planet. Using data from the Wide-field Imager for Parker Solar Probe (WISPR) instrument, scientists … Read more
A powerful geomagnetic storm has doomed 40 Starlink satellites launched by SpaceX last week, the company has announced. Elon Musk‘s company launched a Falcon 9 rocket bearing the 49 satellites from Kennedy Space Center in Florida on Thursday (Feb. 3), but a geomagnetic storm that struck a day later sent the satellites plummeting back toward Earth, … Read more
NASA’s Mars sample-return plan continues to come together. The agency announced on Monday (Feb. 7) that it has selected the aerospace company Lockheed Martin to build the Mars Ascent Vehicle (MAV), a small rocket that will launch pristine Red Planet samples back toward Earth a decade or so from now. “Committing to the Mars Ascent … Read more
At a point some 12,800 years ago, a tenth of Earth’s surface suddenly became covered in roaring fires. The firestorm rivalled the one that wiped out the dinosaurs, and it was likely caused by fragments of a comet that would have measured around 100 kilometers (62 miles) across. As dust clouds smothered Earth, they … Read more
Once, there were giants. Mountain ranges that rivaled the Himalayas in height used to stretch thousands upon thousands of kilometers across the seams of merging supercontinents, billions of years in the past. Like the teeth of decrepit old gods, they’ve long been worn down to their roots by time and decay. But in those … Read more
