Astronomers have discovered what may be the largest-scale structure in the known universe — a group of galaxy clusters and clusters of galaxy clusters that spans roughly 1.3 billion light-years across and contains a mind-boggling 200 quadrillion solar masses. The newfound structure is dubbed Quipu after an Incan system of counting and storing numbers using … Read more
The Euclid space telescope has, by chance, discovered its first Einstein ring, and it is absolutely stunning. Beyond its aesthetic appeal, this perfectly circular Einstein ring has allowed researchers to “weigh” the dark matter at the heart of a galaxy almost 600 million light-years away. The European Space Agency (ESA) spacecraft, which launched in July … Read more
By observing tiny ripples in spacetime called “gravitational waves” that propagate away from colliding black holes, scientists could reveal hidden asymmetries in the universe. The team behind new research on the topic suggests that measuring whether gravitational waves from black hole mergers are right- or left-handed can tell us if the Cosmological Principle — an … Read more
Giant, gas-rich planets may have been able to form more easily in the very early universe than they do today, according to astounding new findings from the James Webb Space Telescope (JWST) that corroborate earlier Hubble Space Telescope evidence. In 2003, Hubble found a massive exoplanet. There’s nothing too unusual about that, but closer inspection … Read more
Napping after overfeeding on food is a dilemma many of us will be fortunate to face on Christmas Day. New research has shown that, billions of years ago, some early black holes also had to nap after overindulging. Using the James Webb Space Telescope (JWST), astronomers spotted a dormant supermassive black hole that existed just … Read more
It’s axiomatic that the Universe is expanding. However, the rate of expansion hasn’t remained the same. It appears that the Universe is expanding more quickly now than it did in the past. Astronomers have struggled to understand this and have wondered if the apparent acceleration is due to instrument errors. The JWST has put that … Read more
