NASA scientists have discovered evidence that a large freshwater lake existed on Mars billion of years ago, further strengthening the case that Earth’s neighbor once harbored life.The lake was part of a network of waterways that could have lasted thousands or even millions of years—possibly long enough for simple organisms to take hold there.Those conclusions come from an analysis of […]

In the sci-fi movie Armageddon, astronauts intercept a killer asteroid heading for Earth, saving mankind. NASA is taking the first step to develop the technology to do just that, by planning a mission to slightly alter an asteroid’s orbit. The mission will also serve as an initial test of a solar-electric propulsion system and other technologies essential for a manned […]

From 2012 to 2015, Russia researched ways of deflecting Earth-bound asteroids using nuclear weapons and came up with a best-case scenario. The Central Scientific Research Institute of Machine Building, an arm of Russia’s state-run Roscosmos space agency, worked on the asteroid problem with other countries (including the United States) in a program called NEOShield, which was largely funded by the […]

NASA’s InSight Steers Toward Mars. The InSight lander has made its first course correction towards Mars. InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is the first mission dedicated to exploring the deep interior of Mars. The lander is currently encapsulated in a protective aeroshell, which launched on top of an Atlas V 401 rocket on […]

An analysis of isotopes in marine fossils from around the world yielded the most complete record of Earth’s temperatures yet—and showed that the planet is heating up at a rate unprecedented in the past 11,300 years. Scientists say that if it weren’t for greenhouse gas emissions, a cooling trend that began 5,000 years ago after a shift in the planet’s […]

Mystery crater: A 40-foot crater has appeared in the ground near Managua airport. Nicaraguan authorities said the hole was caused by a meteorite that broke off from the passing Pitbull, or 2014 RC, asteroid. But NASA officials said that was unlikely, because such a strike would have produced an enormous fireball streaking across the sky, yet nobody reported seeing anything […]

Mysterious radio signals from space have been known to repeat, but for the first time, researchers have noticed a pattern in a series of bursts coming from a single source half a billion light-years from Earth. Fast radio bursts, or FRBs, are millisecond-long bursts of radio waves in space. Individual radio bursts emit once and don’t repeat. But repeating fast […]

Saturn’s ice-covered moon Enceladus could harbor a warm-water ocean beneath its frozen surface, opening up new possibilities for life beyond Earth. Enceladus has fascinated astronomers since 2005, when NASA’s Cassini probe caught geysers on the moon’s south pole spewing out plumes of salty water. Water that is thought to have originated in an ocean buried beneath the moon’s 25-mile-thick ice […]
