Killer electrons in strumming northern and southern lights — ScienceDaily

Computer simulations explain how electrons with wide-ranging energies rain into Earth’s upper and middle atmosphere during a phenomenon known as the pulsating aurora. The findings, published in the journal Geophysical Research Letters, suggest that the higher-energy electrons resulting from this process could cause destruction of the part of the ozone in the mesosphere, about 60 kilometres above Earth’s surface. The study was a collaboration between scientists in Japan, including at Nagoya University, and colleagues in the US, including from NASA.

The northern and southern lights that people are typically aware of, called the aurora borealis and australis, look like coloured curtains of reds, greens, and purples spreading across the night skies. But there is another kind of aurora that is less frequently seen. The pulsating aurora looks more like indistinct wisps of cloud strumming across the sky.

Scientists have only recently developed the technologies enabling them to understand how

KEY POINTS

  • A bright fireball was spotted in western Japan, on Sunday
  • Several cameras captured the moment that the bolide illuminated the surroundings
  • The event was reportedly seen in various regions in Western and Central Japan

A fireball event was spotted in Japan over the weekend. The event was so bright that it momentarily lit up the night sky. 

A bright fireball was spotted at about 1:34 a.m. local time, Sunday in western Japan. According to the International Meteor Organization (IMO), witnesses said that there was a “rumbling noise” then the sky went “totally bright.”

In the video shared by Japan Broadcasting Corporation, NHK on Twitter, a bright greenish ball can be seen streaming in the sky at various locations. It can be seen falling for a few seconds before illuminating the night sky for a brief moment then fizzling out in an instant.

Carol of Lights going virtual, but Texas Tech will still glow for Christmas season

For A-J Media

If there’s one Texas Tech University tradition every Red Raider knows, it’s the Carol of Lights. Held each year near the end of the fall semester, the annual event concludes with the flick of a switch and the glow of more than 25,000 colored bulbs illuminating the 18 buildings around Memorial Circle, the Engineering Key and the Broadway entrance to campus.

The event is presented thanks to the hard work and dedication of students in the Texas Tech Residence Halls Association, part of University Student Housing. Despite the current COVID-19 pandemic, the 2020 Carol of Lights will go on – with some changes. The biggest change? The event, themed “The Matador Lights,” will be entirely virtual.

“There will be no in-person events associated with Carol of Lights this year,” said D’aun Green, senior associate managing director of University Student Housing. “By offering the event virtually, we can

Lights, camera, sell: Retailers want you to watch and shop

NEW YORK — When Jenna Powell gets in front of a camera, she can sell $10,000 worth of sparkly dresses and tie-dye hoodies in 40 minutes.

Powell, whose three Jennaration shops in Alabama were closed at the start of the pandemic, has put all her focus on selling through live videos, broadcasting live several times a week to 400 people who watch on Facebook or her store’s app. She puts on clothes from her shop, spins for the camera and tries to get viewers to buy.

“This top is a deal for $22!,” Powell says in a recent video about a leopard print sweater she’s wearing. “It’s just very, very well made, y’all!”

Livestream selling, already popular in China, is taking off in the U.S., ushering in a new way for Americans to shop online. Instead of searching for what they want, they pick up their phones, sit back, and

After Suffering Irreparable Damage, It’s Lights Out for the Arecibo Observatory’s Iconic Telescope | Smart News

After 57 years of gazing into the universe and helping astronomers unravel the cosmos’ mysteries, the Arecibo Observatory’s world-renowned telescope in Puerto Rico will be torn down, reports Alexandra Witze for Nature.

The observatory has three towers equipped with cables that hold up the telescope’s enormous, 1,000-foot reflector dish. In 2017, Hurricane Maria battered the already deteriorating telescope. This August, an auxiliary cable slipped out of its socket, inflicting a 100-foot-long gash in the dish. Three months later, a main cable connected to that same tower snapped, causing more devastating damage. Teams of engineers looked for remedies to help save the telescope, but repairs would be too risky for a construction team to safely undertake, reports Ashley Strickland for CNN.

Given the age of the telescope, it would need more intensive maintenance in the future since the cables were weaker than originally thought. For this reason, the National Science Foundation

a portable keyboard that lights the way for first-time musicians

Piano lessons for me as a child meant sitting down every Tuesday at a shiny black Yamaha upright, looking up at shelves laden with tributes to my piano teacher’s twin obsessions: busts of classical greats like Beethoven and Chopin, and copies of the Wisden Cricketers’ Almanack, to which he contributed every year. I’d sit and play; he’d sit and criticize. And over the course of a torturous six-year education, my teacher, Mr Dyson, instilled in my grumpy teenage self a love of music I can never adequately thank him for. I did my grades, paid my dues, and I’ve played more or less ever since.

Light’s ‘Clarity’ Depth Camera Could Be A Game Changer

“Light,” a former camera company has announced a new depth sensor that could be a game changer, upending LIDAR and computer vision based depth measurement, by producing a combination RGB image and depth map with ranges out to an astonishing 1000 meters. Presuming it works as promised and can be delivered at scale, this is astonishing news.

Some of you will know Light as a company that made a computational camera with 16 lenses at 3 different focal lengths. Combining the images let them produce a high resolution image with an adjustable depth of field, hoping to get SLR quality in a flat box. The tested their first product, and while interesting, it was not ready for prime-time. They later got money from Softbank. My presumption was they would attempt to use computational photography to
