The universe’s first stars probably ignited 100–250 million years after the Big Bang and died within a few million years. Their ancient light can still reach Earth, but individual stars are so distant and rare that none has been conclusively identified—although cosmic gravitational lenses may finally bring one within JWST’s view.
6+ hour, 11+ min ago (707+ words) Population III stars remain inferred rather than individually confirmed. Extreme cluster lensing may give Webb the magnification needed to isolate one ancient, metal-free source....
Physicist Bhupal Dev at Washington University used the debris from GW170817 — the 2017 neutron star merger — to squeeze new limits on axion-like particles, treating the hot post-collision remnant as a natural forge for dark-matter candidates
4+ day, 17+ hour ago (302+ words) Physicist Bhupal Dev and colleagues have used the multi-year record of GW170817 — the 2017 neutron star merger seen in both gravitational waves and light — to tighten bounds on axion-like particles, treating the hot post-collision remnant as a natural forge for dark matter…...
Nearly every element in your body except hydrogen was forged by stars—the calcium in your bones and much of the iron in your blood came through ancient supernovae, while the hydrogen flowing through you was born before the first star existed.
1+ week, 1+ day ago (982+ words) Hydrogen predates the stars, while generations of stellar fusion, supernovae and galactic recycling supplied the heavier elements now arranged into living bodies....
Every 97 days, a Neptune-sized world looms above Kepler-36b, spanning roughly 2.5 times the apparent diameter of our full Moon. At closest approach, its gravity raises enormous tides that could flex the rocky planet beneath it.
1+ week, 3+ day ago (758+ words) Kepler-36b and its Neptune-sized neighbour pass within about 1.9 million kilometres, creating a giant sky view and a powerful, changing tide across the rocky planet....
Three supermassive black holes have been found packed into a galaxy that existed just 1.2 billion years after the Big Bang — an ancient cosmic pile-up that may explain how the early universe produced such enormous monsters before it had much time to do so
1+ week, 6+ day ago (658+ words) The discovery of three feeding black holes in an infant galaxy offers astronomers a rare glimpse into how the universe assembled its most massive monsters before it had time to build them. Published August 31, 2026 · How we edit Most galaxies get…...
For 21 years, millions of volunteers let UC Berkeley use their home computers to search the sky for alien signals, producing 12 billion detections — after a decade of filtering, scientists narrowed them to roughly 100 targets worth a second look.
2+ week, 14+ hour ago (1591+ words) SETI@home’s 12 billion threshold events became roughly 100 FAST follow-up targets after interference filtering, blind synthetic-signal tests and manual review. By Deep Field · Edited by Lachlan Brown Published August 30, 2026 · How we edit For 21 years, a global network of ordinary computers performed…...
Before JWST began science operations, a dust-sized particle struck one segment of its 6.5-metre mirror at hypervelocity and left an uncorrectable deformation — damage revealed because Webb can detect nanometre-scale changes in its own optical surface.
2+ week, 19+ hour ago (941+ words) Webb detected a permanent deformation on mirror segment C3 through nanometre-scale wavefront sensing, corrected part of it and remained well inside requirements. By Deep Field · Edited by Lachlan Brown Published August 30, 2026 · How we edit Before the James Webb Space Telescope released…...
The universe’s total mass-energy budget, according to standard cosmology: 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy — meaning everything made from the atoms on the periodic table accounts for less than one-twentieth of the cosmos.
2+ week, 1+ day ago (1022+ words) Planck's 2013 universe inventory assigned 4.9% to ordinary matter, 26.8% to dark matter and 68.3% to dark energy, within the standard flat ΛCDM model....
Water covers about 71 per cent of Earth's surface, yet the entire hydrosphere accounts for only about 0.02 per cent of Earth's mass — almost all of the planet's mass is rock and metal beneath it
2+ week, 6+ day ago (301+ words) Ask most people what Earth is made of and, somewhere in the back of the mind, the answer is water....
Astronomers have measured a Saturn-mass object apparently drifting through the Milky Way without a star—and microlensing surveys suggest that unseen free-floating worlds may outnumber the galaxy’s stars, perhaps by as much as 20 to one.
2+ week, 6+ day ago (786+ words) A directly weighed Saturn-mass lens strengthens the free-floating planet case, but the estimate of roughly 20 such worlds per star remains a broad, model-dependent population inference....
