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

The first-of-its-kind study, led by researchers at NASA’s Jet Propulsion Laboratory (JPL) near Los Angeles and published in the journal Nature, raises new concern about how fast climate change is weakening Antarctica’s floating ice shelves and accelerating the rise of global sea levels. The study’s key finding was that the net loss of Antarctic ice … 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

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

Satellite imagery shows Antarctic ice shelf crumbling faster than thought

Satellite imagery shows Antarctic ice shelf crumbling faster than thought

LOS ANGELES, Aug 10 (Reuters) – 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) … Read more
