But they won't be made out of the elements we think of as essential to existence, including carbon, nitrogen, oxygen, silicon and more. Instead, it's just hydrogen and helium, to the 99.9999999% ...

She follows Sir Fred Hoyle’s pioneering example in recording where elements are made, but she goes so much further to record the moment when they are actually formed.

Such heavier elements are necessary to form the dust grains and planetesimals that build planetary cores, according to the study, which was carried out by researchers Jarrett Johnson and Hui Li of ...

The presence of heavy elements was confirmed by observations with the James Webb Space Telescope (JWST), which discovered tellurium in the infrared spectrum of the kilonova. Tellurium is next to ...

Astronomers have detected the first-ever signs of nuclear fission happening in stars, a discovery that sheds light on how elements heavier than those found naturally on Earth form in the cosmos.

Now, by analyzing the chemical composition of 42 ancient stars in the Milky Way, researchers show that the stars produced elements with atomic masses larger than 260, heavier than any element ...
