This gas led to the formation of stars and expansion of galaxies during the early stages of the Universe. A new study by an ...

Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the stars rotate, gas and dust accumulates in a rotating disk around the star ...

Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our sun. Like many small stars, it is not expected to provide suitable conditions for the formation and ...

The search for dark matter requires all the best models, theories, and ideas we can throw at it. A new paper by Julia Monika Koulen, Stefano Profumo, and Nolan Smyth from the University of California ...

For decades, astronomers have wondered what the very first stars in the universe were like. These stars formed new chemical elements, which enriched the universe and allowed the next generations of ...

Starting from the upper left and moving clockwise from large to small scales: upper left —"spiral-like" system; upper right — "bar-like" structure; lower right — rotating infalling envelope; lower ...

Reaction scheme and energetic level of the investigated reaction of the helium hydride ion with deuterium. It is a swift and barrierless reaction, contrary to earlier theories. Background: The ...

The accretion of metal-poor gas sustains galactic star formation. In the Milky Way, this process is fuelled by high-velocity clouds (HVCs), but their fundamental properties have remained elusive in ...

A blazing supermassive black hole can influence far more than its own galaxy. Scientists found that quasars emit radiation strong enough to shut down star formation in nearby galaxies millions of ...

Most events in the universe are not fully understood, including the relatively simple process of star formation. Stars form in dense clouds of cold gas and dust. When these clouds reach a threshold ...

A nearby galaxy is ablaze with new stars in a dazzling new image from the James Webb Space Telescope. Located 45 million light-years from Earth in the constellation Canis Major, this barred spiral ...
