in under 20 seconds, a critical feature for tracking transient phenomena like gamma-ray bursts. When gamma rays from the universe enter Earth’s atmosphere, they produce particle showers. These trigger very brief flashes of blue light that last only...

is exceptional due to its immense journey through space and time. Researchers calculated that the burst occurred when the universe was roughly 3 billion years old, less than a quarter of its current 13.8-billion-year age. By more than doubling the...

and fascinating areas of study in the Large Magellanic Cloud. Every new observation adds a piece to the puzzle of how the Universe’s largest stars reach their end. For now, WOH G64 remains a colossal enigma, 160,000 light-years away. The research was...

Mission scientists suggest these elusive signals may represent some of the earliest stellar explosions to occur in the universe, dating back to its first billion years. As of June 22, 2026, the SVOM mission has logged 318 gamma-ray bursts over two years...

a new methodology for probing the early stages of cosmic history and the fundamental phase transitions that allowed the universe to evolve from a hot, chaotic particle soup into the structured matter observed today. Mapping the Universe Before Atomic...

simulations reveal how ancient stellar explosions shaped the iron patterns found in today’s dwarf galaxies, linking the universe’s first stars. A new suite of sophisticated computer simulations, known as MEGATRON, is providing fresh insights into a...

array still stowed as it was for launch, far from best focus. Roman’s primary science instrument has opened its eyes to the universe for the first time, revealing a sea of out-of-focus stars, each spread out over many thousands of pixels. The image,...

A nonprofit plans to launch humanity’s first interstellar mission to Alpha Centauri by 2029, using solar power and electric thrust for the 80,000-year trek. Reaching another star system usually evokes visions of high-speed light sails or futuristic...

Way, revealing how cosmic giants first assembled. Astronomers have mapped two massive structures dating back to when the universe was just 2.1 billion years old, offering a rare look at the formative stages of the cosmic web. These findings reveal...

framework could become a new tool for translating starlight into reliable cosmological measurements. “We’ve found that the universe is more complicated than we assumed,” Charles Steinhardt concluded, “but we’re also getting closer to measuring it...

New supercomputer simulations suggest dense gas and intense radiation may explain the origins of mysterious supermassive black holes in the early universe. Among the most perplexing targets identified by the James Webb Space Telescope (JWST) are the...

having ample atomic hydrogen reserves. Astronomers investigate why this fuel isn’t being converted into new stars. The universe has been growing increasingly quiet over the last 4.5 billion years, with the frantic pace of stellar birth slowing by a...

a redshift of 2.148. This corresponds to an era approximately 3 billion years after the Big Bang, during the height of the universe’s stellar production known as “cosmic noon.” NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) was able...

arms remain visible. This combination makes the galaxy a valuable laboratory for probing how such objects evolve as the universe ages. “Everything formed in the early universe must transform into something we observe today. We’ve had little insight into...

energetic output. Designated TXS 2354+015, the object hails from the early epoch of the cosmos, dating back to when the universe was less than 1.2 billion years old, or approximately 12.5 billion years in our past. A research team spearheaded by Barbara...
