While a Category 4 hurricane on the Saffir-Simpson hurricane wind scale, NASA-NOAA's Suomi NPP satellite passed over Tropical Cyclone Marcus in the Southern Indian Ocean.
Salts left over from ancient seawater reveal new information about the oxygenation of the Earth's atmosphere more than 2 billion years ago.
On the outskirts of our galaxy, a cosmic tug-of-war is unfolding-and only NASA's Hubble Space Telescope can see who's winning.
NASA's Terra satellite passed over the Arafura Sea and captured an image of newly developed Tropical Cyclone 16P.
ETH Zurich researchers have developed multifunctional origami structures, which they then fabricated into 4-D printed objects. The design principle mimics the structure of an earwig's wing.
One of the MASTER Global Robotic Net telescopes (MSU) located on Tenerife (Spain, Canary Islands) helped the scientists observe the gamma-ray burst caused by the collapse of a star and the formation of a black hole in its place. Usual telescopes are unable to point to gamma-ray bursts error-boxes fast enough to monitor the change in its brightness and obtain any information about its source.
Now a Category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale, Tropical Cyclone Marcus continues to strengthen as it moves south and keeps off-shore from Western Australia. NASA's Terra satellite looked at Marcus in infrared light and saw a well-organized hurricane with a wide eye.
Radar satellite images show a large swath of Texas oil patch is heaving and sinking at alarming rates, according to a geophysical team from Southern Methodist University. Analysis of the images with oil activity data from the Texas Railroad Commission suggests decades of oil activity have destabilized localities of the 4,000-square-mile area, which is populated by small towns, roadways and a vast network of oil and gas pipelines and storage tanks.
New data confirm increased frequency of extreme weather events, European national science academies urge further action on climate change adaptation. Man-made climate change has been proven to have increased recent extreme rainfall and associated floods; coastal flooding due to sea-level rise; heatwaves in Australia, China, and Europe; and increased risks of wildfires with implications for humans and animals, the environment, and the economy. Climate proofing can help to limit these impacts.
To determine the composition of the TRAPPIST-1 planets, the team used a unique software package, developed by Unterborn and Lorenzo, that uses state-of-the-art mineral physics calculators. The software, called ExoPlex, allowed the team to combine all of the available information about the TRAPPIST-1 system, including the chemical makeup of the star, rather than being limited to just the mass and radius of individual planets.
