Life-friendly lake on mars

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 […]

Russia has plans to nuke Earth-bound asteroids, if necessary

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 […]

Mysterious signal from deep space

Mysterious signal from deep space

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 […]

Antarctic Thaw Now Unstoppable

The continued melting of the West Antarctic ice sheet is progressing faster than expected, and the resulting rise in sea levels will have a global impact.The stark new findings point to a potential sea-level rise of up to 10 feet or more in the coming centuries. This increase in the global sea-level will threaten many major cities, including New York, […]

A new water world

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 […]

NASA’s plan to nudge an asteroid

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 […]

InSight Steers Toward Mars

InSight Steers Toward Mars

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 […]

Mapping the moon

Two NASA probes that spent last year orbiting the moon have returned stunning new geological maps that could help explain how it, Earth, and other planets in our solar system formed. The probes, named Ebb and Flow, flew identical orbits just miles above the moon’s surface to measure its gravity field. Slight disruptions in their paths—caused by the push and […]
