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.
One of the best Black Friday streaming deals has landed as Apple TV is over 50% off for six months, so you can stream Pluribus, Severance and more, for less.
All of the proposals floating around out there for invoking dynamical dark energy are a little on the weak side. In many cases, they raise more questions than answers.
NASA has pointed its fleet of spacecraft at comet 3I/ATLAS to collect new footage of the interstellar invader. The agency has also said "all evidence points to it being a comet."
The U.S. Senate will hold a hearing on Dec. 3 to consider the re-nomination of billionaire tech entrepreneur Jared Isaacman as NASA chief.
One of the things the James Webb Space Telescope revealed to us is a class of small, distant galaxies in the very early Universe. Their light has been stretched into the red after billions of years travelling in the expanding Universe, and they've been dubbed Little Red Dots (LRD). Initially, the JWST couldn't reveal their true nature because LRDs are near the limits of the powerful telescope's observational power. But we know they're there; the genie's out of the bottle.
The process of star formation is one of the most fundamental and awe-inspiring phenomena in the universe. It begins within vast, cold, and dense clouds of gas and dust known as molecular clouds or stellar nurseries. These clouds are primarily composed of hydrogen, helium, and trace amounts of heavier elements.
