3D commuting, that's the dream. Soaring over stopped traffic in a lightweight, quiet, safe personal eVTOL aircraft. The Velocitor X-1 joins a growing list of such machines, and it's slated to enter ...

The Bell X-1, a miracle of form and function. Photo-illustration by Cade Martin It was arguably the most important flight since Kitty Hawk, and the plane was a perfection of form and function. Thirty ...

First envisioned in 1783, black holes epitomize mystery and danger like no other object ever known. The singularities at their cores are utterly inexpiable by science — prowlers in the inaccessible ...

Black holes are a tricky bunch. While Einstein’s theory of relativity predicts they’re common, tracking down the first one was quite a challenge. Unlike stars, black holes themselves don’t emit any ...

The Bell Aircraft Corporation X-1-1 in flight with the shock wave pattern in the exhaust plume visible. The X-1 series aircraft were air-launched from a modified Boeing B-29 or a B-50 Superfortress ...

The joint NASA–Italian Space Agency Imaging X-ray Polarimetry Explorer (IXPE) has peered deep into the hot gas surrounding a black hole, in observations that are helping teach us how black holes both ...

More than 60 years after it was first spotted, Cygnus X-1 — the first confirmed black hole — is still full of surprises. Researchers have finally measured the energy output of this behemoth's "dancing ...

Bell received the contract to build three of the original X-1s, then called the XS-1 standing for “Experimental Sonic-1.” The first glide flight test happened in October 1946 while the first powered ...

The alternative text for this image may have been generated using AI. Structures similar to the ring of Cygnus X-1 have been found at the edges of radio lobes inflated by the jets of supermassive ...
