Mysterious ‘little red dot’ galaxies have a possible origin story
Compact ruddy galaxies seen by the James Webb telescope confound astronomers. Having very little spin at birth may explain the galaxies’ small sizes.

In a first, the Webb telescope found a planet by actually ‘seeing’ it
Finding a Saturn-sized world around the young star TWA 7 could pave the way for the Webb space telescope’s direct observation of other exoplanets.

Black hole–shredded megastars power a new class of cosmic explosions
These explosions, called extreme nuclear transients, shine for longer than typical supernovas and get 30 to 1,000 times as bright.

Here’s how a collision of star remnants launches a gleaming jet
A computer simulation shows how two neutron stars of unequal mass merge, form a black hole and spit out a jet of high energy matter.

A possible new dwarf planet skirts the solar system’s edge
For the dwarf planet candidate, one trip around the sun takes over 24,000 years. Its orbit challenges a proposed path for a hypothetical Planet Nine.
