Orbital science, astronomy, remote sensing, and what lies beyond the atmosphere.
The NASA/ESA/CSA James Webb Space Telescope has released a new ESA/Webb Picture of the Month showing Messier 77, a nearby barred spiral galaxy with a dazzling center powered by a supermassive black hole. The image reveals the galaxy’s glowing dust, star-forming structures and brilliant core in infrared light. Messier 77, also known as M77 and…

NASA’s Fermi mission has revealed a hidden relationship between two stellar wrecks in Gemini, where a faint supernova remnant appears to share a dramatic origin story with the famous Jellyfish Nebula. Using 16 years of gamma-ray data, researchers traced high-energy emission from the overlooked remnant and found evidence that both explosions may have come from…
NASA has selected the DAPHNE mission concept to enter Phase B, moving a twin-satellite investigation closer to flight as scientists work to solve a difficult space weather puzzle. The mission will study how activity in Earth’s lower atmosphere can shape the upper atmosphere, where disturbances can affect GPS, satellites in low Earth orbit and astronauts…
A study in Physical Review D proposes that ancient black holes could have survived a cosmic bounce before the Big Bang, leaving behind relics that may still shape the Universe today. The research, led by Enrique Gaztañaga of the University of Portsmouth, explores a striking possibility: some black holes may be older than the hot…
