A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA's Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light those...
Scientists at the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) and their international collaborators have recently developed a new method for efficiently extracting information from galaxy surveys. Their research results are published in the journal...
The origin of life on Earth is still enigmatic, but we are slowly unraveling the steps involved and the necessary ingredients. Scientists believe life arose in a primordial soup of organic chemicals and biomolecules on the early Earth, eventually leading to actual organisms.
Voyager 1 was launched in 1977 and had a planned 5-year lifespan. Current mission duration is 46 and a half years. And counting. As of April 2024, Voyager 1 is 24 billion kilometers from Earth — well beyond the so-called “heliopause” boundary of the Solar System.
