The Big Bang theory is the prevailing cosmological model for the observable universe from the earliest known periods through its subsequent large-scale evolution.
Our friends at PC Gamer hosted a fantastic show looking at the future of video games, and these are our favorite space and sci-fi picks from it.
NASA imaged Comet C/2025 R2 (SWAN) every four minutes for nearly 40 days, marking the longest any comet has been tracked with such frequency.
What are other solar system's like? How is our similar to others, and how is it different? In this age of exoplanet discovery, we've found more than 6,000 confirmed exoplanets, and while some of the planets in our system are similar to exoplanets, the exoplanet population contains planet types that aren't reflected in our system.
Blue Origin's upcoming NS-37 space tourism launch has special significance: One of the passengers is Michi Benthaus, who will become the first wheelchair user in space.
A new view of Mars showcases a dramatic impact crater on the Red Planet with its debris wings unfurling across the surface like a butterfly in flight.

After 25 years of continuous human presence, the International Space Station is heading into its final half decade of planned habitation.
The Global Space Awards will be held at London's Natural History Museum on Dec. 5.
A new analysis of the Solar Orbiter's unique views of the Sun's poles shows how a "conveyor belt" moves within our nearest star.
Is this really a crater in the Saharan Desert?
It’s been over two years since the samples from Bennu gathered by OSIRIS-REx were returned to Earth. But there’s still plenty of novel science coming out of that 121.6 g of material. Three new papers were released recently that describe different aspects of that sample. One in particular, from Yoshihiro Furukawa of Tohoku University in Japan and their co-authors, has already attracted plenty of attention, including from US Senator (and former astronaut) Mark Kelly. It shows that all of the building blocks for early life were available on the asteroid - raising the chances that planets throughout the galaxy could be seeded with the abiotic precursors for life.
December's "Cold Moon" rose on Dec. 4 as it neared its closest point to Earth in its monthly orbit.
What can today's scientists learn about astronomical phenomena from ancient texts?
What can mapped drainage systems on Mars teach scientists about the Red Planet’s watery past? This is what a recent study published in the *Proceedings of the National Academy of Sciences* hopes to address as a team of scientists from the University of Texas at Austin (UT Austin) conducted a first-time mapping study involving Martian river basins. This study has the potential to not only gain insight into ancient Mars and how much water existed there long ago but also develop new methods for mapping ancient river basins on Mars and potentially other worlds.
Your sunscreen sits in the bathroom cabinet, slowly changing. The mayonnaise in your fridge gradually separates. That prescription cream loses effectiveness over time. All these materials share something fundamental, they're soft matter, substances like gels, foams, and colloids whose internal structure reorganises slowly and mysteriously over months or years.
The Moon, waning away from full, groups up with Jupiter, Castor and Pollux on two nights. Later in the week the grand Geminid meteor shower comes into full bloom.
On a summer day in 709 BCE, scribes at the Lu Duchy Court in ancient China looked up to witness something extraordinary. The Sun vanished completely from the sky, and in its place hung a ghostly halo. They recorded the event carefully, noting that during totality the eclipsed Sun appeared "completely yellow above and below." Nearly three millennia later, that ancient observation has helped modern scientists measure how fast Earth was spinning and understand what our Sun was doing at a time when Homer was composing poetry.

A spectacular new view of two dwarf galaxies caught in the middle of a cosmic collision reveals a glowing gas bridge, streams of newborn stars and the ongoing gravitational tug-of-war reshaping both galaxies.
"It means cleaning house, narrowing the viable paths forward, and no longer spending energy on what are evidently dead ends."
