Dark matter is a type of matter that is predicted to make up most of the matter in the universe, yet it is very difficult to detect using conventional experimental techniques, as it does not emit, absorb, or reflect light. While some past studies gathered indirect...
Using NASA’s Fermi Gamma-ray Space Telescope, Chinese astronomers have observed a gamma-ray binary system known as PSR J2032+4127. Results of the new observations, published February 3 on the arXiv preprint server, shed more light on the orbital parameters of...
In a tightly controlled manufacturing hangar west of Paris, workers put the finishing touches on an enormous silver-colored engine. In just a few days, a similar machine will help propel the most powerful version of Europe’s Ariane 6 rocket yet, flying for the...
