The remains of 166 people part of a Celestis Memorial Spaceflight are presumed lost after The Exploration Company's "Mission Possible" capsule presumably crashes into Pacific Ocean.

The fireball was visible from several states including Pennsylvania, New Jersey and Massachusetts.

Recent observations have revealed carbon monoxide venting from the largest comet ever seen, providing clues about its origins in the mysterious depths of the outer solar system

Auroras may be visible from Alaska to Washington as a giant hole in the sun's atmosphere fuels geomagnetic storms with a high-speed solar wind.

The nova appears to be dimming and may soon be undetectable by the unaided eye.

On 26 June 2025 ESA project astronaut Sławosz Uznański-Wiśniewski from Poland and his crewmates arrived to the International Space Station on the Axiom-4 mission (Ax-4).
The Polish project astronaut is the second of a new generation of European astronauts to fly on a commercial human spaceflight opportunity with Axiom Space.
Sponsored by the Polish government and supported by ESA, the Polish Ministry of Economic Development and Technology (MRiT), and the Polish Space Agency (POLSA), the mission will include an ambitious technological and scientific programme with several experiments led by ESA and proposed by the Polish space industry.

The telescope, working with the world's largest digital camera, scans the night sky in search of dark matter.

At the Living Planet Symposium, attendees have been hearing how ESA’s Next Generation Gravity Mission could provide the first opportunity to directly track a vital ocean circulation system that warms our planet – but is now weakening, risking a possible collapse with far-reaching consequences.

The amount of data generated by the Rubin Observatory is going to blow all previous cosmic datasets out of the water, but handling that much information poses a severe challenge.

The observed exoplanet population contains a large number of solar systems where multiple exoplanets follow short orbital periods. The most well-known example of a compact solar system is the TRAPPIST-1 system. There are many others, and exoplanet scientists are trying to understand how they form. Scientists at the Southwest Research Institute (SwRI) may have figured it out.

Mercury doesn't give up its secrets easily. The smallest planet in our Solar System is also one of the most extreme, a sun-scorched, metal-rich world with a puzzling magnetic field and lavas unlike anything found on Earth. Now, groundbreaking laboratory experiments are finally beginning to unlock these mysteries, revealing how this planetary oddball could hold the key to understanding rocky planets throughout the universe.

Pulsars are spinning neutron stars, with several times the mass of the Sun compressed into a sphere just 10 km across. They have a theoretical "death line,” a point where pulsars should stop emitting radio waves as they slow down. But researchers have detected two pulsars still beaming radio signals despite being below this death line. One explanation is that there are tiny irregularities on their surfaces, mountains just 1 cm tall. These peaks amplify local electric fields, making it easier for the pulsars to accelerate particles and produce radio emissions that should be impossible.
