Although general relativity (GR) is an elegant theory of gravity, we don't often need to use it. For most gravitational interactions, Newton's theory of universal gravitation works just fine. Newton's model is good enough ...
For the third time in 35 years, the black hole at the center of the galaxy IC 3599 has erupted, and this time, astronomers were watching it closely. IC 3599, a galaxy roughly 280 million light-years away, has flared this ...
A new study led by astronomers at The University of Texas at Austin proposes a theory that could solve two astronomical riddles at once: the nature of Little Red Dots and the origin of globular clusters. Rather than representing ...
A new study by Queen Mary University of London mathematician Professor Ginestra Bianconi proposes a new perspective on one of the deepest questions in modern physics: How can the universe become increasingly structured and ...
In a single experiment, physicists have measured the "excess" emission of high-energy gamma rays from more than a dozen heavy, unstable atomic nuclei. Mapping the gamma-ray emissions of so many isotopes produced in nuclear ...
Listening to the "ringing" produced by black holes after they collide and merge could allow scientists to test Einstein's theory of general relativity under the most extreme conditions in the universe while unlocking the ...
Despite their depiction as massive monsters that simply suck in everything, including light, astronomers know black holes actually spin. And they spin really, really quickly. Determining just how quickly is key to understanding ...
Peak star formation took place during cosmic noon, between 2–3 billion years after the Big Bang. The star formation rate (SFR) back then was up to 100 times greater than it is today. For the SFR to be so high, gas had to ...
On July 16, 2024, a daytime meteor shook New York City with a sonic boom as it passed just south of the Statue of Liberty. Now, an international team of researchers reports in the journal Science Advances that a short time ...
Astronomers at Durham University have made a major advance in understanding how galaxies formed and evolved in the early universe. Using powerful new observations, the team discovered the most distant example ever found of ...
