Fireworks seen from space station

NASA's astronaut Chris Williams was practicing some nighttime photographs from one of the windows on the International Space Station at the end of the work day on New Year's Eve.

He had just finished passing over his targets when he noticed something funny – the city below him was twinkling! He quickly took a video and realized that as they were orbiting further east, we had orbited into 2026, and he was actually seeing the New Year's fireworks over Baku, Azerbaijan!

A Worsening Air Leak Prompts a Brief Evacuation Order on the Space Station

Five of the seven crew members aboard the International Space Station spent about two hours sheltering in their docked SpaceX capsule on Friday after an air leak on the station's Russian side took a turn for the worse. A leak slowly drains the station's air into the vacuum of space, so a sudden increase is treated as a safety risk.

NASA gave the order on Friday morning and had the astronauts put on their spacesuits as a precaution while Russian engineers worked on the problem. The capsule doubles as the crew's ride home, so moving into it readied them for a fast departure if it came to that. About two hours later, NASA called off the alert and the crew returned to the station while both space agencies tracked how quickly air was still escaping.

The leak is not new. A small passageway on the station's Russian section has lost air on and off for roughly six years, and the rate ticked up again in recent weeks. The agencies say they are still working to monitor and seal it.

The repeated cracking adds to broader worries about the aging outpost, which has circled Earth for more than 25 years and is scheduled to be retired around 2030.

Stars orbiting supermassive black hole at the center of the Milky Way

This time-lapse video from the NACO instrument on ESO's Very Large Telescope in Chile shows stars orbiting the supermassive black hole that lies at the heart of the Milky Way, center of the image, over a period of nearly 20 years.

Happy Asteroid Day 2026

Asteroid Day is the United Nations-sanctioned day of public awareness of the risks of asteroid impacts.

The simulation drops a stony body about 60 meters wide into the atmosphere at 16 km/s on a steep, 30-degree downward path.

High up, the rock falls in one piece while air drag and gravity fight over it. As it reaches denser air, the pressure on its front face climbs. Breakup begins the moment that pressure overpowers the rock's strength, which the model puts near 37 km up.

Once it fails, a particle solver shatters it apart in slow motion. (This video shows) pieces spread, heat up, and dump their energy into the air as a single violent blast, an airburst that leaves no crater.

That matches the Tunguska event on June 30, 1908. Over Siberia, a similar stone exploded around 5 to 10 km up, releasing 10 to 30 megatons and flattening some 2,000 square kilometers of forest, roughly 80 million trees.

60+ million stars in one image

Link to the science release on ESA website

The largest and most detailed photo ever made of our Milky Way galaxy’s centre in visible light is revealed today by the European Space Agency’s Euclid mission.

Packed with more than 60 million stars, this image opens the door for scientists to confirm the existence of any exoplanet found in this region and measure its mass using tiny changes in starlight over time.
