Twilight observations spot 3 large near-Earth objects lurking in the inner solar system Twilight observations with the Dark Energy Camera at the Cerro Tololo Inter-American Observatory in Chile, a program of the U.S. National Science Foundation-supported NOIRLab, have enabled astronomers to spot three near-Earth asteroids, or NEAs, hiding in the glare of the sun. One is the […]
Using new analyses, scientists have just found the last two of the five informational units of DNA and RNA that had yet to be discovered in samples from meteorites. While it is unlikely that DNA could be formed in a meteorite, this discovery demonstrates that these genetic parts are available for delivery and could have […]
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, […]
Researchers at the University of Gothenburg have found traces of two enormous meteorite impacts in the Swedish county of Jämtland, a twin strike that occurred around 460 million years ago. The researchers have discovered two craters in Jämtland. One is enormous, while the other is a tenth of the size of the first. “The two […]
