In-orbit servicing and refueling could help curb the environmental harm done by the space industry. But will operators subscribe to the greener business model? The jury is out.
A newly designed, AI-powered program could solve the puzzle of binary stars in mere seconds using a common laptop, a process that currently takes supercomputer clusters weeks.
Japanese lunar exploration company ispace will attempt to land its RESILIENCE spacecraft on the Moon no earlier than 5 June (CEST) 2025.
On the surface (you're welcome for the joke), Venus is not even close to being hospitable to life. But that's not the end of the story.
Mars is by far the most Earth-like planet in the solar system…but that’s not saying much.
Mars has received considerable attention in the past few decades, thanks to the many robotic missions exploring it to learn more about its past. NASA and China plan to send astronauts/taikonauts there in the coming decades, and commercial space companies like SpaceX hope to send passengers there sooner. This presents several significant challenges, one of the greatest being the lengthy transit times involved. Using conventional propulsion and low-energy trajectories, it takes 6 to 9 months for crewed spacecraft to reach Mars.
The U.S. Astronaut Hall of Fame just held its annual induction ceremony, but one of this year's two honorees could not attend for a reason unique to all past enshrinements.
Mars' core formed within just a few million years, scientists say compared to the hundreds of millions or even billions of years that it took for Earth's core to form — it also might smell like rotten eggs.
The challenge in the search for habitable worlds is clear. We need to be able to identify habitable worlds and distinguish between biotic and abiotic processes. Ideally, scientists would do this on entire populations of exoplanets rather than on a case-by-case basis. Exoplanets' natural thermostats might provide a way of doing this.

Rocket Lab is back at the pad in support of its customer, BlackSky, and the next launch for its Gen-3 satellite constellation. Teams are looking to launch the mission, dubbed ‘Full Stream Ahead,’ from Pad A at Rocket Lab’s launch complex in Mahia, New Zealand, at 11:57 a.m. NZT on June 3 (7:57 p.m. EDT, 2357 UTC on June 2).
As Star Citizen approaches a billion dollars in funding and with no full release date in sight, we take a look at its history and the current state of this ambitious space epic.
Aurora Australisa, or the "southern lights" was on full display on June 1, 2025, as spectators outside Christchurch, New Zealand witnessed firsthand.
Tokyo-based company ispace aims to land its "Resilience" spacecraft in the moon's Mare Frigoris ("Sea of Cold") region on June 5, notching a big milestone for Japan and for commercial spaceflight.

Update June 2, 3:12 p.m. EDT: Added updated forecast information.
A collision between the Milky Way and neighboring galaxy Andromeda is far from a sure thing; in fact, it could hinge on the flip of a cosmic coin.
Over a decade’s worth of NASA/ESA Hubble Space Telescope data was used to re-examine the long-held prediction that the Milky Way galaxy will collide with the Andromeda galaxy in about 4.5 billion years. The astronomers found that, based on the latest observational data from Hubble and Gaia, there is only a 50-50 chance of the two galaxies colliding within the next 10 billion years.
Auroras may be visible from Alaska to Massachusetts geomagnetic storm conditions continue.
The planetary nebula is located 3,000 light-years from Earth in the constellation Draco.
The first quarter moon is the perfect opportunity to explore shadowed craters lining the terminator.
A new study debates the complex ethical questions that must be considered if we're to terraform Mars and lays the blueprint for a potential path forward.
The idea that the Milky Way (MW) and Andromeda (M31) will collide emerged after decades of observations by a host of astronomers. The Hubble played a decisive role in the determination during the early 2000s. It was a triumph of precision astronomy and space telescopes. Now, the Hubble has played an equally important role in cancelling the collision.
