Sir Fred Hoyle was an English astronomer who formulated the theory of stellar nucleosynthesis. He also held controversial stances on other scientific matters — in particular his rejection of the “Big Bang” theory, a term coined by him on BBC radio, and his promotion of panspermia and the Steady-state theory of the universe.

Over time, clumps of dark matter began to gravitationally pull in regular matter, forming recognizable structures, such as galaxies. Galaxies, in turn, coalesced together into massive galaxy clusters that are linked across huge stretches of space by filaments of dark matter, creating what is now known as the cosmic web.

For years, scientists have speculated that magnetic fields within the cosmic web would help to produce shocks that might glow dimly in radio light. Now, for the first time, astronomers have captured this “predicted emission from the formation and growth of the large-scale structure of the Universe,” according to a recent study in Science Advances.

A strange blob has been seen rapidly circling our galaxy’s central black hole. Now, astronomers have identified it as the exploded debris from two merging stars.

The Big Bang was hot, dense, uniform, and filled with matter and energy. Before that? There was nothing. Here’s how that’s possible.

All things physical are information-theoretic in origin and this is a participatory universe… Observer-participancy gives rise to information.

An international team of researchers stumbled upon an exploding supernova in a distant spiral galaxy, using data from the first year of interstellar observation by the James Webb Space Telescope.

The James Webb Space Telescope (JWST or Webb) is an orbiting infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope. It covers longer wavelengths of light, with greatly improved sensitivity, allowing it to see inside dust clouds where stars and planetary systems are forming today as well as looking further back in time to observe the first galaxies that formed in the early universe.

Right now, in the center of our galaxy, an enormous black hole is stretching an object apart like it were taffy. And scientists currently have a rare view, and images, of this extreme cosmic event playing out. A thick cloud of gas and dust dubbed “X7” is rapidly approaching the supermassive black hole Sagittarius A*.
