For the first time, researchers have used lattice quantum chromodynamics to study the interior of neutron stars, obtaining a new maximum bound for the speed of sound inside the star and a better ...

“We were amazed to find such a clear imprint of the different orbital parameters on the climate record,” added lead author Stephen Barker, a professor at Cardiff University, in the UK. “It is quite ...

These varying revolution times are due to each planet's distance from the sun and its orbital speed. Our closest neighbors, Mars and Venus, have similar revolution times to us here on Earth.
