Webb telescope detects non-rotating galaxy from early universe

Reported by AI

Astronomers using the James Webb Space Telescope have identified a massive galaxy that shows no rotation, formed less than 2 billion years after the Big Bang. The finding challenges existing models of galaxy evolution.

The galaxy, known as XMM-VID1-2075, contains several times as many stars as the Milky Way and has already ceased forming new ones. Lead researcher Ben Forrest from the University of California, Davis, described the absence of rotation as surprising and unexpected for such an early object.

James Webb telescope discovers distant jellyfish galaxy

Astronomers using the James Webb Space Telescope have identified the farthest jellyfish galaxy observed to date, located at a redshift of z=1.156. This galaxy, viewed as it appeared 8.5 billion years ago, features trailing streams of gas and young stars shaped by ram-pressure stripping in a dense cluster. The finding suggests that early universe galaxy clusters were more turbulent than previously thought.

Astronomers detect signs of universe's first stars in galaxy Hebe

April 02, 2026 Reported by AI

A galaxy named Hebe, observed 400 million years after the Big Bang, shows evidence of pristine Population III stars formed solely from hydrogen and helium. Researchers led by Roberto Maiolino at the University of Cambridge used the James Webb Space Telescope to confirm spectral lines indicating extremely hot, massive stars. The finding offers insights into the early universe's star formation.

Sun may have migrated from Milky Way center with twin stars

Astronomers have found evidence suggesting that the Sun participated in a large-scale migration of similar stars from the Milky Way's inner regions about 4 to 6 billion years ago. This movement likely carried the solar system to a calmer part of the galaxy. The discovery comes from a detailed study of solar twins using data from the European Space Agency's Gaia satellite.

Researchers uncover diagonal reversal in Milky Way's magnetic field

February 24, 2026 Reported by AI

Astronomers have produced a detailed map of the Milky Way's magnetic field, revealing a surprising diagonal reversal in the Sagittarius Arm. The findings, based on new radio telescope data, help explain how this invisible force structures the galaxy. Led by scientists at the University of Calgary, the studies were published this month in The Astrophysical Journal.
