NASA completes construction of the Nancy Grace Roman Space Telescope, a revolutionary observatory designed to solve the mystery of dark energy 100 times faster than Hubble.
After a decade of coding and 72 million hours of supercomputer time, astronomers have created a virtual universe so accurate it might have just saved the standard model of physics.
The Nancy Grace Roman Space Telescope is set for a September launch, boasting surveying speeds 1,000 times faster than Hubble and an unprecedented budget-friendly completion.
Astronomers have detected a mysterious radio signal from space that repeats on a 16.35‑day clock. The pattern — brief fast radio bursts arriving in a four‑day active window every …
A new LOFAR data release catalogs nearly 13.7 million radio sources across 88% of the northern sky, exposing black-hole jets, galaxy clusters, supernova remnants and other objects…
New Webb observations have ruled out a previously feared collision of asteroid 2024 YR4 with the Moon. Here’s what scientists found, what would have happened if it struck, and why…
A bright fireball streaked across western Europe on 8 March 2026; the European Space Agency is probing the event after fragments reportedly punched a football‑sized hole in a Kobl…
A new simulation from Michigan State University shows how two‑lobed, snowman-shaped Kuiper Belt objects can form naturally by gravitational collapse, and explains how icy grains s…
Researchers find planet that upends the textbook 'rocky-inside, gaseous-outside' view of planetary systems; new data on LHS 1903 point to late, inside‑out formation and force mode…
Researchers at SLAC/Stanford used powerful X-ray beams to read hidden Greek astronomical notes beneath a medieval palimpsest, recovering star coordinates from Hipparchus—the oldes…
A late‑2025 arXiv preprint proposes that the vacuum behaves like a viscous, elastic medium with 'spatial phonons'—a phenomenological model that the author says can reconcile tensi…
Hubble observations show the Neptune-sized exoplanet GJ 3470b leaking a giant hydrogen cloud and shedding mass at a record rate. Astronomers say the planet may be on a long path t…
A new 3D map built from SRG/eROSITA X‑ray data shows low‑density channels in the Local Hot Bubble — including a conspicuous 'tunnel' toward Centaurus — and points to how ancient s…
Comet 3I/ATLAS—only the third confirmed interstellar object to visit our solar system—has been scanned by major radio and optical facilities; scientists report no signs of enginee…
Using Hubble and radio telescopes, astronomers have confirmed a starless, gas-rich dark-matter cloud — nicknamed Cloud‑9 — that matches long-standing theoretical predictions of a …
NASA's SPHEREx mission has completed a full-sky survey in 102 infrared bands, producing a multilayered cosmic atlas that scientists say can turn a flat star chart into a 3D map of…
NASA has finished assembling the Nancy Grace Roman Space Telescope at Goddard, advancing hardware and techniques that could reshape the hunt for habitable worlds and biosignatures…
The newly discovered "twilight" asteroid, 2025 SC79, was obscured by the sun's glare until an astronomer pointed the Dark Energy Camera at it, highlighting the potential dangers o…
