Other Weird Cosmic Threads Discovered Outside Our Galaxy, and They’re Huge

We are getting closer to solving the strange mystery presented by hundreds of enormous filaments hanging from the heart of the Milky Way. For the first time, these long magnetized filaments glowing in radio waves have been observed emerging from other galaxies. Not only are they no longer unique to the Milky Way, but the …

The Webb Telescope is probably spying on the oldest galaxies ever discovered, upending the cosmic timeline

CAPE CANAVERAL, Fla. — NASA’s Webb Space Telescope discovers bright, early galaxies that have been hidden from sight until now, including one that may have formed just 350 million years after the Big Bang that created Earth. cosmos. Astronomers said Thursday that if the results are verified, this host of newly discovered stars would beat …

A cosmic hourglass: Webb captures an image of a protostar shrouded in dark clouds

A cosmic hourglass: Webb captures an image of a protostar shrouded in dark clouds

The L1527 protostar is embedded in a cloud of matter that fuels its growth. Last month, the James Webb Telescope gave us a spectacular new image of the Pillars of Creation, arguably the most famous image taken by Webb’s predecessor, the Hubble Space Telescope, in 1995. Now the telescope gives astronomers for clues about the …

Cosmic chocolate pralines? The general structure of neutron stars revealed

Studying the speed of sound revealed that heavy neutron stars have a hard mantle and a soft core, while light neutron stars have a soft mantle and a hard core, much like different chocolate pralines.

Scientists Tested Einstein's Relativity on a Cosmic Scale and Found Something Strange

Scientists Tested Einstein’s Relativity on a Cosmic Scale and Found Something Strange

Everything in the Universe has gravity – and feels it too. Yet this most common fundamental force is also the one that poses the greatest challenges to physicists. Albert Einstein’s theory of general relativity was remarkably successful in describing the gravity of stars and planets, but it doesn’t seem to apply perfectly to all scales. …

Astronomers discover the closest black hole to Earth - in our cosmic backyard

Astronomers discover the closest black hole to Earth – in our cosmic backyard

Astronomers using the Gemini International Observatory have discovered the closest known black hole to Earth. It is also the first unambiguous detection of a dormant stellar-mass black hole in the Milky Way. Its proximity to Earth, just 1600 light-years away, offers an intriguing study target to advance our understanding of the evolution of binary systems. …
