Antarctica looks like a clean white ice sheet from far away, but the important action happens deep down under the surface. There, the ice meets rock, water, and sediments. That contact zone controls how fast a glacier moves and how easily it can change speed. Recently, scientists uncovered a big secret that Antarctica has been
Last year, NASA’s Curiosity rover made a fascinating discovery after boring into a suspected ancient lake bed on Mars: long-chain organic molecules, called alkanes, that could serve as a potential chemical relic of ancient life on the Red Planet. The molecules, researchers suggested at the time, could have derived from fatty acids, which are common
A team of researchers has successfully analyzed ancient air bubbles trapped in 1.4-billion-year-old salt crystals from northern Ontario, Canada. This unprecedented discovery has provided the first direct measurements of atmospheric oxygen and carbon dioxide levels from the Mesoproterozoic era. This breakthrough comes after years of painstaking research, during which scientists managed to extract and analyze
NASA’s SpaceX Crew-12 Arrival & Welcome Remarks – YouTube Watch On The residents of the International Space Station received a special Valentine’s Day treat. SpaceX‘s Crew-12 astronaut mission docked with the short-staffed International Space Station (ISS) on Saturday (Feb. 14) at 3:15 p.m. EST (2015 GMT), ending a 34-hour orbital chase. “With that gentle contact,
In recent years, 3D printing has advanced rapidly. However, the technology has been trapped in a frustrating tug-of-war. If you wanted something precise, you had to wait hours. If you wanted something fast, you sacrificed the details. But these challenges have been solved by a research team at Tsinghua University, China. Unlike point-by-point or layer-by-layer
WASHINGTON — An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency. Four planets orbit LHS 1903 — a red dwarf star, the most common type of star in the universe — and are
Astronomers have directly observed a massive dying star skip a supernova explosion and instead collapse into a black hole. This event provides the most detailed set of observations ever assembled of a star making that transition, giving researchers an unusually complete view of how stellar black holes form. By combining fresh telescope data with more

More than a century after the RMS Titanic slipped beneath the Atlantic, engineers still chase the dream of ships that refuse to sink. At the University of Rochester’s Institute of Optics, that goal now looks less like fantasy and more like physics. Chunlei Guo, a professor of optics and physics and a senior scientist at
Strange things are afoot in Yellowstone National Park. Since July, U.S. Geological Survey (USGS) scientists have been monitoring an uplift in the surface of the Earth spanning 19 miles near the Norris Geyser Basin. Since then, the mysterious bulge has elevated the area by roughly an inch along the northern rim of the Yellowstone Caldera,
