James Webb Space Telescope reveals the ancient “Big Wheel” galaxy, 11.7 billion light-years away and five times the mass of the Milky Way. Discovered in a dense segment of the early universe, Big Wheel challenges theories about galaxy formation soon after the Big Bang. The discovery, made while observing a distant quasar, reveals clumpy disks […]
The Large Magellanic Cloud (LMC), a satellite galaxy of the Milky Way, hosts a newly discovered supermassive black hole. Astronomers used the European Space Agency’s Gaia satellite to detect this black hole through the observation of hypervelocity stars. Hypervelocity stars result from interactions with supermassive black holes, flinging them through space at immense speeds. This […]
The James Webb Space Telescope captured a stunning image of an Einstein ring in the constellation Hydrus, showcasing gravitational lensing caused by a galaxy cluster named SMACSJ0028.2-7537. This celestial event supports Einstein’s general relativity theory, where massive objects bend the fabric of space-time, allowing light from distant galaxies to curve. The image, enhanced by the […]
