It won't be there forever, but Earth will have a second moon when a small asteroid begins to orbit the planet later this month, space researchers have announced.
The celestial visitor, dubbed 2024 PT5, is from the Arjuna asteroid belt, according to researchers at the NASA-funded Asteroid Terrestrial-impact Last Alert System, or ATLAS, an asteroid monitoring system in South Africa.

A new study by MIT physicists proposes that a mysterious force known as early dark energy could solve two of the biggest puzzles in cosmology and fill in some major gaps in our understanding of how the early universe evolved.
One puzzle in question is the "Hubble tension," which refers to a mismatch in measurements of how fast the universe is expanding. The other involves observations of n
