New observations by three of the world’s largest radio telescopes have revealed that an asteroid discovered last year is actually two objects, each about 3,000 feet (900 meters) in size, orbiting each other. Near-Earth asteroid 2017 YE5 was discovered with observations provided by the Morocco Oukaimeden Sky Survey on Dec. 21, 2017, but no details […]
Using observations from NASA’s Hubble Space Telescope and ground-based observatories, an international team of scientists have confirmed ‘Oumuamua (oh-MOO-ah-MOO-ah), the first known interstellar object to travel through our solar system, got an unexpected boost in speed and shift in trajectory as it passed through the inner solar system last year. “Our high-precision measurements of ‘Oumuamua’s […]
A new multiagency report outlines how the U.S. could become better prepared for near-Earth objects—asteroids and comets whose orbits come within 30 million miles of Earth—otherwise known as NEOs. While no known NEOs currently pose significant risks of impact, the report is a key step to addressing a nationwide response to any future risks. NASA, […]
On May 3, the Kilauea volcano on Hawaii’s Big Island erupted from new fissures and sent lava flowing over streets and neighborhoods. As the disaster response on the ground lead by the U.S. Geological Survey kicked into gear, managers from NASA’s Earth Science Disasters Program heard from response agencies and sent out a call to NASA’s own […]
