Cosmic rays coming from outside the Solar System bring these particles closer to the Sun, where they experience changes caused by heat and other types of solar energy. It is possible that ...

Chris Gunn—NASA “Part of our core science for Roman is to do surveys that allow us to measure the properties of very large numbers of galaxies throughout cosmic history,” says Schlieder ...

The halo, known as an Einstein ring, encircles a galaxy 590 million light-years away, considered close by cosmic standards. A light-year is 5.8 trillion miles. Telescopes spy a monster radio jet ...

That timeline means that this supermassive black hole, estimated to have a mass around 200 million times that of the sun, existed in a vital cosmic period known as the "epoch of reionization." ...

Scientists have detected cosmic waves that sound like chirping birds in an unexpected place NEW YORK -- Scientists have detected cosmic waves that sound like birds chirping in an unexpected place.

However, Lane and his colleagues tested an alternative idea called the timescape model, which suggests that the apparent acceleration could be a byproduct of cosmic structures like voids — vast ...

What is the structure of our physical reality? Physicists have long imagined space and time interweaving into “space-time”, the metaphorical fabric that underlies the cosmos. But there may be ...

Elementary particles were created. And, eventually, the cosmic flash dance left behind scars in the fabric of space-time. Physicists call them cosmic strings. Like stretch marks left on skin that ...

Stargazers are in for a cosmic treat as six planets align in a breathtaking display known as a planetary parade. This astronomical event is set to unfold across the night sky, showcasing Venus ...

The other tactic is to go back in time, all the way to near the beginning. The cosmic microwave background (CMB) radiation is the light emitted 379,000 years after the Big Bang. Before this time ...

As the star spins, these beams sweep past Earth and produce periodic pulses of radio waves, much like a cosmic lighthouse. This behaviour has earned them the name “pulsars”. Pulsars typically ...
