Scientists identify a star with record-low heavy elements outside the Milky Way
A dim star orbiting the Milky Way is drawing attention for its almost pristine composition. Named PicII-503, it contains barely any heavy elements, making it one of the most extreme examples of an ...
A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an ...
Scientists now understand that the universe forges its heaviest elements, including californium, through extreme cosmic events like neutron star mergers. These cataclysmic collisions provide the ...
Gold and other heavy elements are born in some of the universe’s most violent events—but scientists still struggle to understand the nuclear steps that create them. Now, nuclear physicists have ...
Still in its original galaxy, a rare holdout from the second generation of stars sheds new light on the origins of the elements—and how massive supernovae reshaped the cosmos ...
GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...
A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of ...
Discovered in the Pictor II dwarf galaxy, star PicII-503 has an extreme deficiency in iron—less than 1/40,000th of the sun. This signature makes it the clearest example of a star within a primordial ...
Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.
The birth of massive stars involves gravity, turbulence, and stellar feedback, all of which influence the flow of matter. Find out more here: ...
In 2023, astronomers using NASA’s Chandra X-ray Observatory and Hubble Space Telescope spotted an unusual class of short gamma-ray bursts, whose origin appeared to be the collision of two neutron ...
