James Webb Telescope Reveals Chaotic Early Formation of the Universe’s First Galaxies

/in /tarafından

New observations from the James Webb Space Telescope (JWST) reveal that the first galaxies in the universe were far more chaotic and turbulent than the orderly spiral and elliptical galaxies we see today. Researchers at the University of Cambridge analyzed over 250 galaxies formed 0.8 to 1.5 billion years after the Big Bang, finding that most were clumpy, irregular, and dominated by turbulent gas motions. Unlike modern galaxies, these early systems struggled to settle due to intense gravitational forces and rapid star formation, which stirred their gas and prevented stable rotation. Devamını Oku

NASA’s Europa Clipper Could Fly Through Comet Tail, Providing Unique Look at Interstellar Material

/in /tarafından

NASA’s Europa Clipper spacecraft, currently en route to study Jupiter’s icy moon Europa, may have a rare opportunity to pass through the tail of an interstellar comet. Between October 30 and November 6, the spacecraft is expected to encounter a stream of charged particles emitted by comet 3I/ATLAS, a visitor from another star system that has been traveling through the solar system for over a year. If the timing aligns, this could allow scientists to study interstellar material directly, without the need to launch a dedicated mission to chase the comet. Devamını Oku

New Photos of Interstellar Object 3I/ATLAS Reveal Massive Jet Pointing Toward the Sun

/in /tarafından

Newly captured images of the interstellar comet 3I/ATLAS reveal a spectacular jet of gas and dust shooting directly toward the Sun, offering scientists a closer look at the object’s natural behavior. First detected in late June and confirmed by NASA in July, 3I/ATLAS originates from a distant star system and is only the third interstellar object ever observed entering our solar system. Measuring between 5 and 11 kilometers wide, it is the largest interstellar visitor discovered so far and may also be the oldest, with an age estimated at billions of years, predating the formation of the Sun.
