Do dark matter and dark energy exist?

Researchers have hypothesized that the universe contains “dark matter.” They have also posited the existence of “dark energy.” These two hypotheses account for the movement of stars in galaxies and for the accelerating expansion of the universe.

NASA telescope studies quirky comet 45P

When comet 45P zipped past Earth early in 2017, researchers observing from NASA’s Infrared Telescope Facility, or IRTF, in Hawai’i gave the long-time trekker a thorough astronomical checkup. The results help fill in crucial details about ices in Jupiter-family comets and reveal that quirky 45P doesn’t quite match any comet studied so far.
