  NASA’s SPHEREx Mission Sends First Space Images Before Full Sky Survey

  NASA’s SPHEREx telescope has captured its first images from space, marking a critical milestone before its full-sky infrared survey begins. The observatory, launched on March 11, recorded thousands of light sources, including distant galaxies and stars. Unlike other space telescopes, SPHEREx is designed for large-scale cosmic mapping, scanning th...

  James Webb Space Telescope Reveals a Stunning Einstein Ring in Hydrus

  A striking new image from the James Webb Space Telescope reveals an Einstein ring in the Hydrus constellation. The phenomenon occurs when a massive foreground galaxy bends light from a hidden background galaxy, forming a near-perfect ring. This effect, predicted by Einstein’s theory of general relativity, helps astronomers study galaxies from the...

  Space Telescope Gaia Sent Into 'Retirement' But Legacy Endures

  Europe's Gaia space telescope was powered down and sent into "retirement" on Thursday after a decade revealing the secrets of the Milky Way, but its observations will fuel discoveries for decades to come.

  ESA’s Euclid Telescope Releases First Data, Mapping 26 Million Galaxies

  ESA’s Euclid telescope has released its first dataset, mapping 26 million galaxies within a week. The observations include deep-field images, a survey of 380,000 galaxies, and 500 new gravitational lens candidates. Scientists will continue tracking cosmic evolution over six years. The dataset, currently 35 terabytes, is expected to grow to 2 peta...

  Hubble Telescope Captures NGC 4536, a Starburst Galaxy with Intense Star Formation

  NASA’s Hubble Space Telescope has captured a striking image of NGC 4536, a starburst galaxy 50 million light-years away in the Virgo constellation. The galaxy’s sweeping spiral arms are filled with young blue star clusters and ionized hydrogen gas, indicating rapid star formation. Astronomers believe its bar-like structure channels gas toward t...

  Smallest Galaxy Ever Found: Andromeda XXXV Defies Cosmic Evolution Models

  Astronomers have discovered Andromeda XXXV, the smallest and faintest known galaxy, located 3 million light-years away. It challenges existing models of galaxy formation, as similar small galaxies were thought to be destroyed in the early universe. Researchers are studying how it retained conditions for star formation despite harsh cosmic environme...

  Water May Have Formed in the Universe 100 Million Years After Big Bang

  A new study suggests water formed in the universe just 100–200 million years after the Big Bang, much earlier than previously estimated. Researchers examined ancient supernovas to understand how oxygen combined with hydrogen to create water. If confirmed, these findings could change perspectives on when the conditions for life first emerged. The ...

  Unexpected Rotational Motion Detected in Ultra-Diffuse Galaxies of Hydra Cluster

  Astronomers studying ultra-diffuse galaxies (UDGs) in the Hydra cluster have observed unexpected rotational movement in nearly half of the 30 galaxies examined. Spectroscopic data from the LEWIS programme, using the MUSE instrument on the Very Large Telescope, suggests that gravitational interactions with larger galaxies may influence their formati...

  NASA’s SPHEREx Telescope Launching Aboard SpaceX Falcon 9 to Explore Cosmic Evolution

  NASA’s SPHEREx telescope, launching on Feb 28 aboard a SpaceX Falcon 9, will map the entire sky in infrared, observing 450 million galaxies and 100 million Milky Way stars. The mission aims to uncover the large-scale structure of the universe, track icy molecules in interstellar space, and study cosmic inflation. Equipped with a spectrophotometer...

  Astronomers Spot Galaxy NGC 3640 With a Past of Consuming Smaller Galaxies

  Recent observations of NGC 3640 reveal a history of merging with smaller galaxies. Located 88 million light-years away, the elliptical galaxy is suspected to be on a collision course with NGC 3641. The Very Large Telescope captured structural distortions, hinting at previous mergers. Researchers have identified ancient stars acting as fossil marker...

  Strange Fast Radio Bursts Emerge from an Ancient Dead Galaxy, Baffling Scientists

  Scientists have detected mysterious fast radio bursts (FRBs) from the outskirts of an 11 billion-year-old dead galaxy. This discovery challenges the belief that FRBs primarily originate from young, star-forming galaxies. Researchers suspect the bursts may result from colliding stars or a collapsing white dwarf. The Canadian Hydrogen Intensity Mappi...
