James Webb telescope uncovers massive 'grand design' spiral galaxy in the early universe — and scientists can't explain how it got so big, so fast
Galaxies in the early universe tend to be clumpy, but the new JWST discovery of a "grand design" spiral galaxy just 1.5 billion years after the Big Bang has scientists stumped.
James Webb telescope spies stunning 'Firefly Sparkle' galaxy — a baby clone of the Milky Way being 'assembled brick by brick' in the early universe
The James Webb Space Telescope has captured an image of a baby, Milky Way-like galaxy that formed more than 13 billion years ago. This "Firefly Sparkle" galaxy could reveal how our own galaxy evolved.

James Webb space telescope offers best glimpse ever into the icy planetesimals of the early solar system
New studies led by researchers at the University of Central Florida offer for the first time a clearer picture of how the outer solar system formed and evolved based on analyses of trans-Neptunian objects (TNOs) and centaurs.
NASA's James Webb Telescope Reveals Universe Expanding Faster Than Thought
The rate of expansion of the universe today is a figure known as the Hubble constant, which is typically measured in units of kilometers per second per megaparsec (km/s/Mpc), where a megaparsec (Mpc) is about 3.26 million light-years.
Webb telescope confirms the universe is expanding at an unexpected rate
Fresh corroboration of the perplexing observation that the universe is expanding more rapidly than expected has scientists pondering the cause - perhaps some unknown factor involving the mysterious cosmic components dark energy and dark matter.
