The James Webb Space Telescope has discovered the “Big Wheel,” a massive spiral galaxy 11.7 billion light-years away, dramatically altering concepts of early galaxy formation. This galaxy, five times the Milky Way’s mass, challenges existing cosmological models about galaxies just two billion years post-Big Bang. Characterized by a red core and spanning 100,000 light-years, the…
Astronomers discovered a supermassive black hole within the Large Magellanic Cloud, a satellite galaxy of the Milky Way. This black hole, with a mass 600,000 times that of the Sun, was identified by tracking hypervelocity stars using the ESA’s Gaia satellite. The movements of these stars, propelled to high speeds, pointed to the influence of…
Celestial orbits are more complex than simple circles, often taking eccentric paths around stars. Historical models, like the Ptolemaic system, attempted to explain planet movement with complicated mechanisms before Kepler’s discovery of elliptical orbits. Kepler revealed that planets travel in ellipses, with the concept confirmed by telescopic observations, such as Jupiter’s moons. Newton’s gravitational theory…
