Astronaut captures a meteor exploding in the atmosphere over Earth

An incredible new video taken by a NASA astronaut living aboard the International Space Station shows an epic explosion over Earth. But it’s not warfare or any other man-made horror that created the bang: instead, it is thought to be a meteor exploding as it hits the planet’s atmosphere.

Astronaut Matthew Dominick has been busy with his camera this week, as he has already captured a gorgeous time-lapse video of his view from the station. But he also spotted this bright flash of teal-green light in his footage, which he slowed down to one frame per second to show the flash seen over the Nile Rver.

The object is thought to be a bolide, also known as a fireball, a type of extremely bright meteor that occurs when a piece of rocky asteroid or icy comet enters the Earth’s atmosphere and glows brightly.

I showed this to a couple of friends yesterday to see what they thought. They both thought it was a meteor exploding in the atmosphere – a rather bright one called a bolide. Timelapse is slowed down to one frame per second for you to see it streaking and then exploding.

It was pure chance that allowed Dominick to capture this event, he wrote on X: “Time-lapse was set up over Northern Afric,a where it was very dark with lightning. I got greedy with ISO (25600) and when the time-lapse got to Cairo, the cities were overexposed. I was greedy because I wanted the Milky Way Core. When I went to review the shots afterwards, I found the bolide. ”

A longer and faster version of the same footage shows how the event appeared to Dominick, as a very brief flash:

Here is a longer and faster frame rate version of the timelapse. I think it is interesting to compare the size of the bolide blast to other objects in view like the mediterranean, Cairo, or lightning strikes. pic.twitter.com/oQZnfAeVqg

This has been a busy time for asteroids as the asteroid 2024 RW1 was also seen from the Earth’s surface this week when it burned up in the sky over the Philippines. That resulted in a bright green fireball as well, in a dramatic event that lit up the sky, though fortunately no one was hurt, no damage has been reported, and the event was declared to be harmless. This wasn’t the same event that Dominick observed though, as Dominick confirmed that his event was seen on September 2, while the fireball over the Philippines occurred on September 4.

The event in the Philippines is remarkable for another reason, as it was one of the few asteroids that was identified before it hit the planet. Astronomers spotted the object around eight hours before it struck the atmosphere, allowing them to prepare to take observations before its arrival. With increasingly sophisticated asteroid observation technology, space watchers are now able to occasionally predict the impact of objects ahead of time.

NASA astronaut reveals ‘the coolest thing about the space station’
The International Space Station.

In a recent video chat with earthlings, NASA astronaut Nick Hague talked about what makes the International Space Station (ISS) so special.

“The coolest thing about the space station is the reason why we’re here -- it’s to do science in a weightless environment,” the American astronaut said alongside fellow ISS inhabitant and ace space photographer Don Pettit.

See the stunning cosmic clouds captured in new Hubble image
This NASA/ESA Hubble Space Telescope reveals clouds of gas and dust near the Tarantula Nebula, located in the Large Magellanic Cloud about 160,000 light-years away.

This gorgeous new image from the Hubble Space Telescope shows something once considered little more than an annoyance: cosmic dust. For many years, astronomers thought of dust as a problem which blocked out important objects from view, but in recent decades they have learned about dust's importance in forming stars and planets, and even making new molecules in space.

The image shows clouds of dust and gas located near the Tarantula Nebula, a place also renowned for its beauty. It is part of a satellite galaxy of the Milky Way called the Large Magellanic Cloud, located 160,000 light-years away and a hotbed of star formation.

This distant exoplanet has an atmosphere ‘like something out of science fiction’
Tylos (or WASP-121b) is a gaseous, giant exoplanet located some 900 light-years away in the constellation Puppis. Using the ESPRESSO instrument on ESO’s Very Large Telescope (VLT), scientists have been able to prove into its atmosphere, revealing its 3D structure. This is the first time that this has been possible on a planet outside of the Solar System. The atmosphere of Tylos is divided into three layers, with iron winds at the bottom, followed by a very fast jet stream of sodium, and finally an upper layer of hydrogen winds. This kind of climate has never been seen before on any planet.

For decades, astronomers have been wondering about planets beyond our solar system -- called exoplanets -- and whether we could learn about these far-off worlds. With the introduction of tools like the James Webb Space Telescope, we're now able to not only detect exoplanets, but also to learn about them in detail. Recently, astronomers created the first 3D view of an exoplanet atmosphere, letting them peer into the climate of another world.

The researchers used a ground-based telescope, the European Southern Observatory’s Very Large Telescope (ESO’s VLT), which consists of four telescopes that work together to take detailed readings of distant objects. They found that exoplanet WASP-121b, which has surface temperatures of over 3,000 Kelvins, or 5,000 degrees Fahrenheit, is so hot that metals like iron and titanium can be whipped up into the atmosphere, carried by powerful winds.
