Why do galaxies look so different from one another? From beautiful blue spirals like our Milky Way to golden ellipticals like the Messier 87? ESA’s Euclid space telescope is beginning to answer this ...

The existence of massive, elliptical galaxies in the early universe has puzzled astronomers for two decades. An international team led by Nikolaus Sulzenauer and Axel Weiß from the Max Planck ...

Astronomers using the James Webb Space Telescope have spotted something that shouldn’t exist—at least not so early in the ...

Astronomers may have uncovered the origins of the mysterious “little red dots,” some of the strangest galaxies seen in the early universe. These tiny but brilliant objects, discovered by the James ...

How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion years, but observations of galaxies in our universe imply shorter ...
