After the formation of the sun, there was a tremendous amount of debris in its orbit. Most of this debris coalesced to form the planets and their moons. Some of this debris never became part of the p… [+6166 chars]
The James Webb Telescope is now at its optimal cooling temperature, its mirrors calibrated and has its targets set. The flying observatory will look for evidence of the first black holes that formed … [+2619 chars]
Astronomers may examine how two stars exchange stardust by using NASAs SOFIA airborne telescope, which has been following a dance between two stars orbiting each other as they approach the moment of … [+3191 chars]
Astronomers have discovered the first strong evidence that black hole merger events can generate a kick large enough to spin a black hole out of its galaxy. The team, which included Vijay Varma, a s… [+5210 chars]
Chemical reactions that are driven by light offer a powerful tool for chemists who are designing new ways to manufacture pharmaceuticals and other useful compounds. Harnessing this light energy requi… [+5425 chars]
An international team led by a University of Sydney scientist has discovered an unusual radio signal emitting neutron star that rotates extremely slowly, completing one rotation every 76 seconds. Th… [+1949 chars]
