After weeks of unrest that has waxed and waned, Agung in Indonesia finally produced an explosive eruption today. This blast wasn’t anything close to the large blast that certain parts of the media have been claiming, but rather a relatively small eruption (see below) that was driven by water flashing to steam at the summit crater of the volcano.

For being an island in the North Atlantic, Iceland has a lot of volcanoes. Some of them generate a lot of anxiety when they have the inevitable rumbles. An earthquake swarm at Katla or Hekla causes all sorts of media alarms to go off … which is surprising considering the last three eruptions in Iceland ...read more
The NOAA-20 satellite was to be the first of four, but the Trump Administration has sought to delay and massively cut the program

Scientists now have an idea of what the first recorded extra-solar asteroid looked like.
The hunk of rock of that whipped through the solar system in October looks like no other asteroid we’ve seen before, they say, long and thin like a javelin and colored red from millions of years of accumulated radiation exposure. The coloration wasn’t surpr ...read more

Machines are becoming increasingly adept at creating content. Whether it be news articles, poetry, or visual art, computers are learning how to mimic human creativity in novel — and sometimes disturbing — ways.
Text-based content is fairly easy for computers to generate. Anyone who has used a smartphone to text knows that operating systems are pretty savvy in predicting speech patterns. But videos and other visual mediums are a little more challenging — not ...read more

If you’ve seen the news over the weekend, you might have seen a bevy of article proclaiming that 2018 will see a big surge on M7+ earthquakes. My first reaction was “ugh” and the next was “sigh”. I thought that yet again the media was being duped by crackpots trying to sell some snake oil prediction scheme.
However, that first pass may have been misguided, but ...read more

Elon Musk finally revealed the Tesla Semi, an electric big-rig he professes will outstrip the diesel fleets that have dominated American freight for decades.
The Tesla CEO flaunted his latest creation and its “BAMF performance”—it’s a technical term, he says—at an unveiling ceremony Thursday night in Hawthorne, CA. He outlined the semi’s specs, which include parlor tricks like going from 0-60 mph in 5 seconds and potentially industry-upending ...read more
A portrait of the world’s most recognizable person, Jesus Christ, painted by an icon whose renown doesn’t trail too far behind, Leonardo da Vinci, on Wednesday sold at auction for $450.3 million, setting a new record for artistic largesse.
Only a handful of authentic da Vinci paintings exist today, and Salvator Mundi is the only one that could still be purchased by a deep-pocketed collector. Christie’s Auction House billed the work as “The Last da Vinci,” “th ...read more

Antarctica, a land of near-lunar desolation and conditions so bleak few plants or animals dare stay, was once covered with a blanket of lush greenery.
The conception of the ice-coated continent as a forested Eden emerged in the early 1900s when Robert Falcon Scott, a British explorer, found plant fossils during an expedition to the South Pole. Now, researchers working in the Trans-Antarctic mountains, where they may be the first to tread ...read more
