For the first time in history, scientists have succeeded in visually capturing the speed of light. Through an innovative use of high-speed photography and lasers, researchers have managed to photograph light as it moves, revealing its behavior at speeds near the cosmic limit. The groundbreaking achievement brings light-speed motion into clear view, offering both a
A recent test to confirm repairs to the Space Launch System (SLS) rocket’s fueling system faced problems of its own, casting doubt over NASA’s ability to fix a recurring issue ahead of the Artemis 2 launch window in March. NASA recently performed a confidence test on newly replaced seals in an area used to load
Scientists at the University of California San Diego have identified the enzyme responsible for chromothripsis, a dramatic genetic event in which a chromosome breaks into many fragments and is stitched back together in the wrong order. This chaotic reshuffling allows cancer cells to evolve quickly and develop resistance to treatment. Although chromothripsis was first recognized
In 1966, three years before the first humans walked on the Moon, the Soviet Union landed a small, spherical probe, dubbed Luna 9, on the lunar surface. It was a historic moment, with the spacecraft becoming the first to achieve a soft landing and return the first photo from the surface of another celestial body:
A new physics model attempts to explain puzzling measurements of how fast galaxies are moving away from us, proposing that empty space behaves like a fluid with built-in drag. In this view, the force driving the universe’s expansion would not stay constant over time, but could strengthen, weaken, or briefly overshoot, changing how we understand
The universe is a vast, unseen loom, weaving galaxies into an intricate cosmic web through invisible threads of matter. This cosmic web is the fundamental scaffolding of everything we see, dictating where galaxies form and how they evolve. Much of this architecture remains a mystery, its delicate pathways hidden, and uncovering these cosmic threads requires
A Cornell physicist has calculated that the universe may be nearing the halfway point of a total lifespan of about 33 billion years. Using newly released data from major dark energy observatories, he concludes that the cosmos will continue expanding for roughly another 11 billion years before reaching its largest size. After that, it would
NOVAStar is 365Astronomy’s own in-house brand of telescopes and accessories. Its latest addition, the Scarlet A62Q quadruplet refractor, is a budget-friendly instrument aimed at beginners starting out in astrophotography. Unboxing and setting up The 520mm f/8.4 telescope arrived in a sturdy, foam-lined carry case that secures it snugly and protects it well for storage. The thoughtful
Scientists are investigating the origin of one of the most energetic particles ever seen hitting Earth from space. The Amaterasu particle, named for the Japanese sun goddess, was first detected in 2021, carrying 40 million times more energy than particles accelerated by the world’s largest and most powerful particle accelerator, the Large Hadron Collider (LHC).
The Extremely Large Telescope’ss 80-meter-tall dome takes shape in the Atacama Desert. (Image credit: ESO/G. Vecchia) The European Southern Observatory has released a new view of the Extremely Large Telescope (ELT), as its colossal outer dome nears completion at Cerro Armazones in Chile’s Atacama Desert. What is it? Captured in December 2025, the newly released
