Drastic climate change

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 […]

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 […]

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 Highlights Drought, Mars, Arctic Warming at Science Conference

Long ago, in the largest canyon system in our solar system, vibrations from “marsquakes” shook soft sediments that had accumulated in Martian lakes. The shaken sediments formed features that now appear as a series of low hills apparent in a geological map based on NASA images. The map was released today by the U.S. Geological Survey (USGS). This map 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 […]
