A new study led by UNLV scientists sheds light on how planets, including Earth, formed in our galaxy—and why the life and ...

Astronomers studying how elements heavier than iron were produced in the early Milky Way have identified a distinct series of epochs of galaxy-wide chemical formation. This evolutionary timeline, ...

Why did they form at that time? Astronomers know from observing distant exploding stars that the size of the universe has ...

Among the billions of stars that populate the cosmos, some retain the chemical signature of ancient times, long before heavy ...

Two professors from Arizona State University and one from the University of North Carolina at Chapel Hill are fascinated by stars and the elements they create. Sumner Starrfield and Frank Timmes from ...

Elements heavier than iron, such as gold and uranium, are primarily formed through neutron capture processes, specifically the rapid neutron capture process (r-process). The r-process, unlike the ...

A star found in the Large Magellanic Cloud is remarkably unpolluted by heavier elements, suggesting it is descended from the ...

Carl Sagan’s famous quote underscores one of the most profound and fundamental facts of astronomy: the planets, stars and galaxies that appear so unimaginably far away from us are in fact connected to ...

In a new study, astronomers report novel evidence regarding the limits of planet formation, finding that after a certain point, planets larger than Earth have difficulty forming near low-metallicity ...

Scientists have found a star unlike any other one recorded—which may change our picture of how stars die. This unusual star, 13,000 light-years away, has an elemental makeup that suggests it was ...

Deep near-infrared color composite image of the L1688 cloud in the Ophiuchus star-forming complex from the VISIONS European Southern Observatory public survey, where blue, green and red are mapped to ...

A strange, newly measured clump of stars orbiting the nearby Andromeda galaxy has the lowest level of heavy chemical elements ever seen in one of these mysterious star clusters. Named RBC EXT8, this ...
