In his new paper, Professor Jonathan Tan, an astrophysicist at the University of Virginia and the Chalmers University of Technology, proposes that Population...
The first generation of stars (Population III) must have formed from the unenriched gas that permeated the infant Universe. These stars produced the first...
Described in a paper that appears today in the journal Nature Astronomy, the discovery means habitable exoplanets could have started forming much earlier...
GN-z11 is an exceptionally luminous galaxy that existed when our Universe was only 420 million years old, making it one of the earliest and most distant...
The first generation of stars in the Universe is yet to be observed. There are two leading theories for those objects: hydrogen burning Population III...
Early Universe’s stars had up to several hundred solar masses. The earliest stars of 140-260 solar masses became pair-instability supernovae (PISNe)....
Astronomers using ESO’s Very Large Telescope (VLT) have detected three distant gas clouds whose chemical composition matches what they expect from the...
In unveiling the nature of the first stars, the main astronomical clue is the elemental compositions of the second generation of stars, observed as extremely...
The two newfound galaxies, dubbed GLASS-z12 and GLASS-z10, existed approximately 350 and 450 million years after the Big Bang.
GLASS-z12 (redshift of 12.5)...
The very first stars likely formed when the Universe was only 100 million years old. Known as Population III stars, these stellar objects were so massive...
The newly-discovered galaxy, named HD1, existed when the Universe was just 330 million years old.
