Sierra Space won’t stop blowing up inflatable space station modules (video)

NeRD

Sierra Space has announced the completion of another full-scale burst test in which the company exploded one of its inflatable modules being developed as part of efforts to build a commercial space station. Sierra Space’s “Ultimate Burst Pressure test” was conducted on June 18, 2024 and involved an inflatable space station module built to full scale at more than 20 feet tall (6 meters). The test unit, which compares to the size of a typical family home, is about one-third the volume of the International Space Station (ISS) at 10,600…

Earth’s plate tectonics fired up hundreds of millions of years earlier than we thought, ancient crystals reveal

NeRD

The plate tectonics that cause earthquakes, build mountains and split continents may have started when Earth was in its infancy, new research finds — significantly earlier than many scientists previously thought.  The new study suggests plate tectonics started more than 4 billion years ago — not long after the planet formed 4.5 billion years ago. In this era, known as the Hadean, Earth was fresh and piping hot, with an ammonia-and-methane atmosphere imbued with enough water to eventually condense into a planet-wide ocean. During this period, Earth cooled enough to…

This Week In Space podcast: This Week In Space podcast: Episode 121 —An Exploding Star Near You!

NeRD

An Exploding Star Near You! – A Nova is Coming with Carlos Badenes – YouTube Watch On On Episode 121 of This Week In Space, Rod Pyle and Tariq Malik discuss a star about to go nova with astrophysicist Dr. Carlos Badenes. A nova is a star that periodically sheds mass in a huge flare-up of light and energy. This nova will be visible in the night sky for about 6-7 days! T Corona Borealis (TCrB) is a binary system comprising two stars in the constellation Corona Borealis that bursts…

‘Double’ meteor shower will light up the skies next week. Here’s how to watch.

NeRD

Stargazers will soon be able to witness a “double” meteor shower as both the Alpha Capricornids and the Southern Delta Aquariids peak next week.  The twin-skywatching event is “just an amazing coincidence,” Nicholas Moskovitz, a planetary astronomer at Lowell Observatory in Arizona, told Live Science. Meteor showers occur when Earth’s orbit intersects a comet’s path. The rocky debris left behind by the comet burns up as it enters Earth’s atmosphere. During the double meteor showers this month, Earth will cross the orbits of comet 96P/Machholz — which causes the Southern…

Lego sets up ‘space station’ at San Diego Comic-Con, offers mission crew patch

NeRD

Lego is recruiting new members for its “mission crew,” issuing rocket builders with an exclusive mission patch at this year’s San Diego Comic-Con (SDCC). The toy company has launched “Space Station 8R1CK5,” a sprawling booth that highlights many of its recent space-themed building sets within a setting that was inspired by both sci-fi and real-life orbiting outposts. Show-goers will find photo opportunities, panels and show-only opportunities inside Space Station 8R1CK5 (booth 2829), which is open through the convention’s close on Sunday (July 29). “Space is an endless playground for imagination…

A moon of Uranus could have a hidden ocean, James Webb Space Telescope finds

NeRD

Using the James Webb Space Telescope (JWST), astronomers discovered that Ariel, a moon of Uranus, could be hiding in a buried liquid water ocean.  The discovery could supply an answer to a mystery surrounding this Uranian moon that has perplexed scientists: the fact Ariel’s surface is covered with a significant amount of carbon dioxide ice. This is puzzling because at the distance Uranus and its moons exist from the sun, 20 times further out from the sun than Earth, carbon dioxide turns to gas and is lost to space. This…

Sun blasts out most powerful flare of current solar cycle, sends massive coronal mass ejection into space (video)

NeRD

On Tuesday (July 23), Europe’s Solar Orbiter (SolO) spacecraft witnessed an extremely powerful X14 class solar flare erupt from the far side of the sun. Although it was not the most powerful flare ever recorded, which was estimated at roughly a X45 back in 2003, solar flares of this magnitude can result in longer-lived radiation storms and even world-wide blackouts if they are directed at Earth. The X-class are the leaders on the classification scale, and blast out energy 10 times more powerful than M class flares, which is second…

‘Wonderlab’ host Emily Calandrelli will fly to suborbital space with Blue Origin

NeRD

The Space Gal is headed to the final frontier, as part of Space for Humanity’s Citizen Astronaut Program.  Emily Calandrelli, known for her Emmy-nominated Netflix science series “Emily’s Wonder Lab,” was selected to launch to suborbital space as a citizen astronaut ambassador with Blue Origin, though the launch date has not yet been set.  “I’m incredibly grateful for the opportunity to fly with Blue Origin,” Calandrelli, a West Virginia native, said in a statement from Space for Humanity. “I look forward to representing my home state in this way and…

Discovery of ‘dark oxygen’ from deep-sea metal lumps could trigger rethink of origins of life

NeRD

Potato-size metallic nodules strewn across the Pacific Ocean seafloor produce oxygen in complete darkness and without any help from living organisms, new research reveals. The discovery of this deep-sea oxygen, dubbed “dark oxygen,” is the first time scientists have ever observed oxygen being generated without the involvement of organisms and challenges what we know about the emergence of life on Earth, researchers say. “When we first got this data, we thought the sensors were faulty, because every study ever done in the deep sea has only seen oxygen being consumed…

X-rays reveal secret gas in huge and distant galaxy cluster

NeRD

By combining a new image of a giant galaxy cluster with older X-ray data, scientists at the European Space Agency (ESA) have demonstrated how the cluster’s galaxies are suffused by huge amounts of gas that can reach scorching temperatures up to 100 million degrees Celsius (180 million degrees Fahrenheit). The galaxy cluster, Abell 2390, was imaged recently by ESA’s Euclid mission, designed to study dark matter and dark energy by probing gravitational lensing occurrences in galaxy clusters. Because these clusters contain so much mass — up to ten trillion solar…
