Did giant impacts start plate tectonics?

Did giant impacts start plate tectonics?

One of Earth’s defining features is its plate tectonics, a phenomenon that shapes the planet’s surface and creates some of its most catastrophic events, like earthquakes, tsunamis, and volcanic eruptions. While some features of plate tectonics have been spotted elsewhere in the Solar System, the Earth is the only planet we know of with the … Read more

Debris found on Mars surface likely netting, NASA says

Debris found on Mars surface likely netting, NASA says

NEWYou can now listen to Fox News articles! NASA’s Jet Propulsion Laboratory (JPL) says that a viral image of a clump of stringy material photographed on the surface of Mars is likely Dacron netting. The material is also used in thermal blankets, according to an agency blog post. However, before the string could be imaged … Read more

A story about a weird “magic switch” at MIT

A story about a weird "magic switch" at MIT

The Jargon File is “a comprehensive compendium of hacker slang illuminating many aspects of hackish tradition, folklore, and humor.” The first version was compiled in 1975 by a computer scientist at Stanford named Raphael Finke. It’s been maintained by various people and hosted on various computers over the years but in recent decades the canonical … Read more

Astronomers May Have Discovered the Youngest Planet Ever Detected in Our Galaxy

Circumplanetary Disk Star AS 209

Scientists studying the young star AS 209 have detected gas in a circumplanetary disk for the first time, which suggests the star system may be harboring a very young Jupiter-mass planet. Science images from the research show (right) blob-like emissions of light coming from otherwise empty gaps in the highly-structured, seven-ring disk (left). Credit: ALMA … Read more

August full moon: When to see the sturgeon supermoon

August full moon: When to see the sturgeon supermoon

Named by the Native American Algonquin tribe after sturgeon fish that were more easily caught in the Great Lakes and other bodies of water during this time of year, the sturgeon moon ends 2022’s series of four supermoons, which began in May, according to The Old Farmer’s Almanac. After sunset, look toward the southeast to … Read more

Antarctica ice sheet crumbling faster than previously thought, satellite imagery shows

Antarctica ice sheet crumbling faster than previously thought, satellite imagery shows

Antarctica’s coastal glaciers are shedding icebergs more rapidly than nature can replenish the crumbling ice, doubling previous estimates of losses from the world’s largest ice sheet over the past 25 years, a satellite analysis showed on Wednesday. The first-of-its-kind study, led by researchers at NASA’s Jet Propulsion Laboratory (JPL) near Los Angeles and published in … Read more

Scientists uncover ancient source of oxygen that could have fueled life on early Earth

Scientist in a lab coat is pictured injecting something into a small glass vial on a lab bench

Powerful earthquakes that shook Earth some 3.8 billion years ago split open the planet’s crust and allowed chemical reactions to unfold deep within the fractured rock. These reactions, fueled by seismic activity, water and near-boiling temperaturesmay have provided oxygen to some of the world’s earliest life forms, a new study suggests. This oxygen would have … Read more

NASA's Fermi telescope confirms star wreck as source of extreme cosmic particles

Illustration of NASA’s Fermi Gamma-ray Space Telescope at work. Credit: NASA’s Goddard Space Flight Center Conceptual Image Lab Astronomers have long sought the launch sites for some of the highest-energy protons in our galaxy. Now a study using 12 years of data from NASA’s Fermi Gamma-ray Space Telescope confirms that one supernova remnant is just … Read more

New image of colliding galaxies previews the fate of the Milky Way :: WRAL.com

By Ashley Strickland, CNN A new telescope image showcases two entangled galaxies that will eventually merge into one millions of years from now — and previews the eventual, similar fate of our own Milky Way galaxy. The Gemini North telescope, located on the summit of Maunakea in Hawaii, spotted the interacting spiral galaxies about 60 … Read more
