How James Webb Space Telescope data have already revealed surprises

A distant galaxy cluster’s violent past and the onset of star formation in the more remote universe lie buried in the observatory’s first image.

Clouds in the Milky Way’s plasma bubbles came from the starry disk — and far beyond

Gas clouds in the Fermi bubbles have a wide range of chemical compositions, suggesting some may have been ripped from other galaxies.

A fast radio burst’s rapid, steady beat offers a clue to its cosmic origin

Amped-up neutron stars, pairs of magnetically entangled neutron stars or magnetar quakes could explain a three-second-long train of radio blips.

An otherwise quiet galaxy in the early universe is spewing star stuff

Seen as it was 700 million years after the Big Bang, the galaxy churns out a relatively paltry number of stars. And yet it’s heaving gas into space.

Gravitational wave ‘radar’ could help map the invisible universe

Gravity ripples scattering off warped spacetime near massive objects might help astronomers peer inside stars and find globs of dark matter.

Seven newfound dwarf galaxies sit on just one side of a larger galaxy

Seven newly found dwarf galaxy candidates are stick to just one side of the large galaxy M81. Astronomers don’t know why.

Neutrinos hint the sun has more carbon and nitrogen than previously thought

Scientists still don’t know the sun’s exact chemical composition, which is crucial for understanding the entire universe. Neutrinos will help.
