ST. LOUIS ? Quark stars, exotic objects thathave yet to be directly observed, are part of a new theory to explain some ofthe brightest stellar explosions recorded in the universe.

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Physicist Murray Gell-Mann, one of the ...

For a large star, death is a bit of a squeeze. Once its nuclear fuel is spent, its core collapses, sparking a dramatic supernova explosion that blasts away the outer layers. The body left is a cold, ...

Recreating the conditions present just after the Big Bang has given experimentalists a glimpse into how the universe formed. Now, scientists have begun to see striking similarities between the ...

Thanks to a new development in nuclear physics theory, scientists exploring expanding fireballs that mimic the early universe have new signs to look for as they map out the transition from primordial ...

Three American physicists shared the $1,3-million Nobel prize for physics for calculating the bizarre properties of the ultimate fragments of matter. They provided the mathematics for a completely new ...
