Astronaut captures ‘unreal’ aurora image from space station

A geomagnetic storm caused by a series of recent explosive events on the sun has brought spectacular auroras to parts of Earth in recent days.

Astronauts on the International Space Station (ISS) 250 miles above our planet have also been enjoying the amazing light show, with ISS inhabitant Josh Cassada sharing a stunning image that he captured just recently.

“Absolutely unreal,” Cassada tweeted alongside the image, which shows not only the gorgeous greens of the aurora, but also city lights on Earth, and part of the space station.

Auroras happen when particles from incoming solar storms strike gases in Earth’s atmosphere. The resulting collisions often result in these colorful displays above Earth’s surface.

Here on terra firma, the natural phenomenon is usually best viewed in the far north in places like Alaska, Canada, Iceland, Greenland, Norway, Sweden, and Finland. On the other side of Earth, in the far south, places like Tasmania and New Zealand are usually the best spots to view an aurora.

But in recent days, particularly powerful solar flares from the sun have caused the aurora to stretch much further south than usual, giving skywatchers who live in those locations a rare chance to see the light show without having to trek to locations in the far north or south.

As for ISS astronauts, their enviable location means it’s not unusual for them to witness a number of aurora during their six-month missions aboard the orbital outpost.

Cassada, for example, will likely have seen a few other aurorae while living and working in space, as he arrived at the ISS five months ago as part of SpaceX’s Crew-5 team.

But judging by the comment in his tweet, this latest one appears to have moved him the most.

Asimov’s vision of harvesting solar power from space could become a reality
Simplified diagram of space solar power concept..

It's an idea straight out of science fiction: A space station orbits around Earth, harvesting energy from the sun and beaming it down to our planet. Isaac Asimov popularized the concept in his 1941 story Reason, and futurists have been dreaming about it ever since.

But this notion is more than just an idle fantasy -- it's a highly practical concept being pursued by space agencies across the world, and it's almost within reach of current technologies. It could even be the solution to the energy crisis here on Earth.

See planets being born in new images from the Very Large Telescope
This composite image shows the MWC 758 planet-forming disc, located about 500 light-years away in the Taurus region, as seen with two different facilities. The yellow colour represents infrared observations obtained with the Spectro-Polarimetric High-contrast Exoplanet REsearch (SPHERE) instrument on ESO’s Very Large Telescope (VLT). The blue regions on the other hand correspond to observations performed with the Atacama Large Millimeter/submillimeter Array (ALMA).

Astronomers have used the Very Large Telescope to peer into the disks of matter from which exoplanets form, looking at more than 80 young stars to see which may have planets forming around them. This is the largest study to date on these planet-forming disks, which are often found within the same huge clouds of dust and gas that stars form within.

A total of 86 young stars were studied in three regions known to host star formation: Taurus and Chamaeleon I, each located around 600 light-years away, and Orion, a famous stellar nursery located around 1,600 light-years away. The researchers took images of the disks around the stars, looking at their structures for clues about how different types of planets can form.

Amazing Earth photos shared by outgoing ISS astronaut
Earth as seen from the International Space Station.

Andreas Mogensen became the first Dane in orbit when he arrived at the International Space Station (ISS) as part of SpaceX’s Crew-7 in August 2023.

After just over six months aboard the orbital outpost, the astronaut is now preparing to head back to Earth with his three colleagues aboard a SpaceX Crew Dragon spacecraft.
