Cosmologists have been trying to figure out the different measurements of the universe’s expansion speed for almost ten years. This event, known as the Hubble tension, is a big problem for modern cosmology. Because it is so strange, it changes the basic ideas of cosmology. Now, a radical theory suggests that the answer lies in ...
Mario Rana, an amateur astronomer and NASA contributor, pointed his telescope at Saturn on the morning of July 5, 2025. He may have seen history being made. Astronomers around the world are trying to figure out if this was the first time anyone has ever seen an impact on Saturn. There was a brief but ...
In a cosmic battle 3.8 billion light-years away, two galaxy clusters crashed into each other with such force that they tore apart the fabric of spacetime. This left behind a lot of clues about dark matter. NASA’s James Webb Space Telescope (JWST) has now given us the clearest picture yet of the Bullet Cluster, a ...
NASA’s astronaut, Nichole “Vapor” Ayers, has photographed a spectacular atmospheric event – a large red ‘jellyfish’ sprite soaring above a thunderstorm in North America. The striking image, taken from the International Space Station (ISS) on July 3, 2025, gives scientists a rare view of sprites from the top which is a form of lightning and ...
Tragic and bestowed with a sense of ambition, a German aerospace startup’s endeavor to deliver heavenly memorials and perform unique agricultural experiments in space ended in the Pacific Ocean. Aboard a SpaceX Falcon 9 rocket, the Exploration Company launched a Nyx capsule containing human remains and cannabis seeds. The female capsule’s operational orbit was reached ...
The extraordinary features of a rapidly moving celestial object are scintillating astronomers’ interest. Upon initial discovery, A11pl3Z was given a name but recently NASA has confirmed it as 3I/ATLAS, the third interstellar object out of four comets or asteroids discovered. Unlike the comets or asteroids which are bound to the sun’s asteroid belt and viewable ...
Jupiter-sized exoplanets which emerge as a proxy for accelerating self-sabotage by instigating tremendous outbursts from their parent stars seem as violations to the conventional structure of planetary systems; astronomers have identified such a diabolic planet, HIP 67522 b. Located within its parent star’s magnetic field, HIP 67522 b’s orbital position subjects it to flare beams ...
The irrefutable visual proof of a star dying in a spectacular “double detonation,” the explosive death of a star which occurs in twinned strokes, has now been recorded. This event marks the first instance of a white dwarf star undergoing two rapid explosions. The unprecedented finding offers new insights into the supernova remnant SNR 0509-67.5, ...
Astronomers have been trying to figure out what “hot Jupiters” are for decades. These are gas giants that orbit very close to their stars and complete a full revolution in just a few hours. But their rarer cousins, double hot Jupiters, are even more mysterious. In a binary star system, two of these planets orbit ...
Astronomers have found a rare Jupiter-sized planet hiding at the edge of the Milky Way using a phenomenon that Albert Einstein predicted more than a hundred years ago. This is part of a cosmic detective story that has been going on for years. Gravitational microlensing, which uses the bending of space-time itself, found the exoplanet ...
