Researchers investigated three mysterious objects in the early universe. Shown here are their color images, compiled from three NIRCam filter bands aboard the James Webb Space Telescope. They are remarkably compact at red wavelengths (earning them the name “little red dots”), with some evidence of spatial structure at blue wavelengths.

A new explanation for why we haven’t found dark matter suggests it doesn’t exist. Instead, the author thinks we have misunderstood gravity. He is not the first to suggest this, but the new proposal, of gravity without mass, created by topological defects in space-time, is particularly novel. Dark matter was first proposed in 1932, based … Read more
Imagine you are a ham radio enthusiast, alone at night, idly working your way through the radio spectrum when you come across a broadcast on a disused shortwave transmitter, where there is normally only static electricity. The broadcast is a tune, or a buzz, or sometimes cartoon character Yosemite Sam saying, “Varmint, I’m going bbb-bloooow … Read more
Off the coast of Big Sur, California, deep beneath the waves, lies a mysterious landscape littered with large holes in the clay, silt and sand. Decades after its discovery, scientists from the Monterey Bay Aquarium Research Institute (MBARI) and Stanford University believe they have discovered what makes up the field’s curious circular pattern. The generally … Read more
