Physicists Designed an Experiment to Turn Light Into Matter
Plasma could be wrangled to collide photons and yield matter, according to physicists who ran simulations to explore the practical applications of a world-famous equation. Gizmodo’s Top Five Gadgets of…
Webb and Hubble Telescopes Team Up to Image ‘Mothra’ and a Massive ‘Christmas Tree’ Cluster
It’s not yet December, but NASA is already in a festive mood: the Webb and Hubble space telescopes recently imaged MACS0416, a pair of colliding galaxy clusters 4.3 billion light-years…
Live Reveal: Euclid Space Telescope’s First Glimpse of the Dark Universe
The European Space Agency’s $1.4 billion Euclid space telescope is charged with revealing the dark universe—the 95% of the cosmos we don’t see. On Tuesday, the telescope’s first images will…
The Euclid ‘Dark Universe’ Space Telescope Is Off to a Faltering Start
The European Space Agency’s Euclid space telescope launched from Earth on July 1 and has since been getting set up to begin its investigation of the dark universe. But the…
Shell Galaxy Reveals Its Onion-Like Layers to Dark Energy Camera
Behold a galactic onion: the shell galaxy NGC 3923, spotted by the Cerro Tololo Inter-American Observatory’s Dark Energy Camera (DECam) at a distance of about 70 million light-years from Earth.…
Measuring Helium in Distant Galaxies May Give Physicists Insight Into Why the Universe Exists
When theoretical physicists like myself say that we’re studying why the universe exists, we sound like philosophers. But new data collected by researchers using Japan’s Subaru telescope has revealed insights…
Scientists Propose Webb Telescope Has Detected Stars Powered by Dark Matter
Astronomers looking at ancient light seen by the Webb Space Telescope have found three pinpricks that they think could be “dark stars,” theoretical objects powered by dark matter. First Full-Color…
Researchers want to use gravitational waves to learn about dark matter
When two sufficiently massive objects collide — such as when two black holes merge — the forces can actually bend space-time, creating ripples called gravitational waves. These gravitational waves can…
Euclid mission launches to probe the mysteries of dark matter
The European Space Agency (ESA) has successfully launched its Euclid space telescope to study the mysteries of dark matter and dark energy. The spacecraft launched from Cape Canaveral in Florida…
