A Falcon 9 rocket lifted off from the Kennedy Space Center Thursday evening on a milestone mission marking the 100th launch from the Space Coast this year.
Interstellar objects are really rather rare. Since astronomers first spotted 'Oumuamua racing through our Solar System in 2017, we've detected only two more visitors from beyond; comet Borisov in 2019, and now 3I/ATLAS, discovered on 1 July 2025. These objects offer tantalising glimpses into other stellar systems, carrying material formed around distant stars. But they don't linger. They sweep through on hyperbolic trajectories, never to return, which makes every observation precious.
"This challenges our understanding of black hole and galaxy formation in the early universe."
Without water, life is highly unlikely, as far as scientists understand it. The entire idea of a habitable zone around other stars is based on a planet's potential to have liquid water on its surface. But where does this water come from?
Blue Origin plans to build an even more powerful version of its partially reusable New Glenn rocket, which aced its second-ever launch just last week.
"The most convincing scenario is that most of the building blocks of Earth and Theia originated in the inner solar system. Earth and Theia are likely to have been neighbors."
Now that Comet 3I/ATLAS has emerged from the Sun's glare, its behavior is being monitored by every available observatory.
A record-breaking number of stars has been mapped by a new model that speeds up processing time while allowing smaller scale events, such as supernova explosions, to be incorporated into the simulation alongside larger-scale galactic processes.
The Cygnus X star-forming region is about 4,600 light-years away. It contains a huge number of massive protostars, and one of the most massive star-forming molecular clouds known. With all of this activity, it's not surprising that it also hosts some objects that have puzzled astronomers.
Uranus will appear opposite the sun in Earth's sky on Nov. 21.
These Nikon Monarch M7 8x42 binoculars are great for any stargazer looking for a budget-friendly investment.
SpaceX will launch more than 100 different payloads today (Nov. 20) on the Transporter 15 rideshare mission.
"The discovery of this stream highlights how much is still unknown about the life histories of galaxies, how the hidden universe shapes the realms that we can see."
The European Space Agency (ESA) brings public and ESA-wide recognition of the outstanding performance of European companies working in the frame of ESA programmes and projects.
Smile has passed its qualification and flight acceptance review, meaning that it meets all requirements for launch. The launch window has been set for 8 April to 7 May 2026.
It's not every day you see both a comet and an aurora from low Earth orbit.
Waste no time with the Unistellar Odyssey Pro — a lightweight, portable smart telescope that features in our best smart telescopes guide.
Over the course of billions of years, the universe has steadily been evolving. Thanks to the expansion of the universe, we are able to “see” back in time to watch that evolution, almost from the beginning. But every once in a while we see something that doesn’t fit into our current understanding of how the universe should operate. That’s the case for a galaxy described in a new paper by PhD student Sijia Cai of Tsinghua University’s Department of Astronomy and their colleagues. They found a galaxy formed around 11 billion years ago that appears to be “metal-free”, indicating that it might contain a set of elusive first generation (Pop III) stars.
Chevron 7 is locked, as Amazon greenlights a new 'Stargate' show for Prime Video led by longtime franchise figure Martin Gero.
The unique system features two rare Wolf-Rayet stars, and a supergiant companion that is interrupting the flow of the dust shells that the two Wolf-Rayet stars cast off.

The press conference, at the European Astronaut Centre in Cologne, Germany, follows the signing of contracts between Thales Alenia Space Italy, UK and France, OHB system AG (Germany) and Nammo (UK) for the ESA’s lunar lander programme Argonaut.
