A new model predicts that the universe could begin to collapse in about 10 billion years. (Image credit: ALFRED PASIEKA/SCIENCE PHOTO LIBRARY via Getty Images) A new paper claims that the expected lifespan of the universe is much shorter than…
Pluto’s equator is partially covered in icy ridges known as “blade terrain.” A new study suggests there are more of these skyscraper-sized features than previously thought. (Image credit: JPL/NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute) A new study has…
NASA’s James Webb Space Telescope has captured the deepest, sharpest infrared image of the distant Universe to date. This image of the galaxy cluster SMACS 0723, dubbed the First Webb Deep Field, is remarkably detailed. (Image credit: NASA, ESA, CSA,…

A new study shows that most of the inner rocky planets in the solar system once orbited the sun in perfect alignment. (Image credit: SCIEPRO/Getty Images) The solar system’s four terrestrial planets, including Earth and a long-lost world, likely formed…
NASA has released a collection of nine new images created by the Chandra X-ray Observatory using the Hubble and JWST telescopes. This new series of images from NASA’s Chandra Space Telescope, which was launched in 1999, shows what different objects…
Scientists have created a stunning animation showing the suspected intermediate-mass black hole HLX-1 tearing apart a star, causing a bright tidal disruption event. (Image credit: NASA, ESA, Ralf Crawford (STScI)) Astronomers believe they have discovered an extremely rare type of…
The Sun’s gravitational pull extends out to more than 160 times farther than Neptune’s. (Image credit: Vadim Petrakov via Shutterstock) Is there a huge, undiscovered planet at the edge of the solar system? The concept has been around since Pluto…
Illustration of a giant molecular cloud (Image credit: NSF) Astronomers have discovered a colossal cloud of gas and dust that stretches for as much as 200 light years and is hidden in a poorly studied region of the Milky Way.…
(Image credit: NSF/AUI/NSF NRAO) A team of scientists led by the National Science Foundation’s Green Bank Observatory (NSF GBO) recently identified an unusually rare object known as a long-period radio transient (LPT), designated CHIME J1634+44. These objects resemble rotating radio…
These images from the Solar Dynamics Observatory show the Moon’s path across the Sun on July 25, 2025. (Image credit: NASA/SDO and the AIA, EVE, and HMI science teams) A near-Earth spacecraft has just witnessed a rare event: a lunar…
