Human remains lost after memorial spaceflight capsule crashes into the sea

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.

See a vivid green fireball light up the northeastern US (video)

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

Northern lights may be visible in these 10 US States tonight

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.

A star exploded in the Lupus constellation. Here's how to see the nova in the night sky this month

V462 Lupi will soon vanish from the night sky, but before it does, the dark skies around the new moon present a perfect time to head away from city lights to hunt down the light from this ancient nova.

Ax-4 joins the International Space Station

Video: 00:02:36

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.

Alien life could survive deadly stellar radiation, Earth's desert lichen reveal

A walk in the desert and a curious discovery could have revealed that the secrets of alien life grow in the harshest conditions on Earth in the form of lichen.

Rubin Observatory takes its 1st look at the night skies | Space photo of the day for June 26, 2025

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

New ESA gravity mission to detect weakening ocean conveyor

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.

Cosmic images from the world's largest digital camera are so big they require a 'data butler'

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.

Webb Directly Images A Saturn-Sized Star In A Nearby System

One of Webb’s strong points is its ability to directly image planets around another solar system. The telescope has been in operation for long enough now that a flood of those images are starting, as more and more systems come under the telescope’s gaze. One of those is described in a recent paper and press release from NASA. According to the paper, the planet in a nearby system is about the size of Saturn, which would make it the smallest planet ever found by direct observation.

Watch MTG-S1 and Sentinel-4 launch live

The second of the Meteosat Third Generation (MTG) satellites and the first instrument for the Copernicus Sentinel-4 mission are ready for liftoff at Cape Canaveral in Florida, US. Live coverage of this launch will be shown on ESA WebTV, not earlier than Tuesday, 1 July.

NASA's been pulling out of major astronomy meetings — and scientists are feeling the effects

NASA and the National Science Foundation cancelled their major events at a major astronomy conference this summer. Scientists who attended were left disappointed.

Earth tones on Mars

The European Space Agency’s Mars Express has captured a swirl of colour on the Red Planet, with yellows and rust-oranges meeting deep reds and browns. Lurking within this martian palette are not one but four dust devils, each snaking their way across the surface.

Satellite records expose fire driving Gran Chaco transformation

At ESA’s Living Planet Symposium, scientists have unveiled how the combination of different long-term, high-resolution satellite datasets from ESA’s Climate Change Initiative is shedding new light on the South American Gran Chaco – one of the world’s most endangered dry forest ecosystems. These data reveal, in remarkable clarity, that fire is the primary driver of widespread, accelerating deforestation across the region. 

A fast radio burst detected last year turned out to be from long-dead NASA satellite

Fast Radio Bursts (FRBs) have remained a mystery to astronomers even since the first was detected in 2007 (known as the Lorimer Burst). These quick bursts typically last for mere nanoseconds, though some have been found to last up to 3 seconds, and their precise cause remains unknown. In recent years, scientists have traced a few FRBs back to their source and have determined that they came from neutron stars. This has led to the theory that FRBs are caused by compact objects, though this has yet to be proven.

Schweickart Prize Goes to a Plan for Managing Asteroid Mining Risks

The $10,000 Schweickart Prize is awarded every June to mark Asteroid Day and draw attention to risks from above — and this year's prize is going to a team of students who are proposing a panel to focus on what could happen when we start tinkering with asteroids.

From the Cape to the constellation: SpaceX launches 27 more Starlink satellites (video)

SpaceX launched a batch of 27 Starlink satellites into low Earth orbit from the Cape Canaveral Space Force Station in Florida on Wednesday, June 25, 2025.

Watch live: Axiom-4 astronauts aboard SpaceX Crew Dragon dock with International Space Station on June 26

After more than 24 hours on orbit, the the private astronaut crew of Axiom-4 will catch up to the International Space Station to dock for their two-week mission.

A Framework To Ensure Lunar Resources Are Available To All

Space exploration enthusiasts tend to overlook the regulatory aspects of their desired goals. They focus on technologies and the science we can do with them rather than mundane things like property rights or environmental considerations. However, in the long run, those enthusiasts will have to grapple with all aspects of exploration programs as they begin to affect more and more of the public. With such foresight, various groups have started putting forward ideas for frameworks of how to holistically think about how to utilize the Moon, as that seems the most likely first stepping stone out to the wider solar system. A new paper from Ekaterina Seltikova and her colleagues at the Space Generation Advisory Council (SGAC) and the University of Toronto puts forth one such framework, with a particular focus on how to develop a lunar economy that is open for everyone.

How Solar Flares Can Change the Weather on Exoplanets

When astronomers search for potentially habitable planets beyond our Solar System, they typically focus on whether these worlds orbit at the right distance from their stars to maintain liquid water. But new research reveals that violent flares and eruptions from host stars may be equally important in determining whether these distant worlds could support life.

Antarctica is the Perfect Place to Study Snowball Earth

Scientists studying tiny life forms in Antarctica's ice covered ponds have discovered compelling evidence that similar environments could have sheltered complex life during one of Earth's most extreme periods, the so called "Snowball Earth" era.
