The young star B335, which hasn't grown up yet, suddenly sneezed, and that sneeze is still going on. Astronomers spotted the outburst in the scattered light from its outflow cavity, and it offered a rare chance to see how such an energy release affects a jet — a stream of gas shooting out…

There is something wildly generous about a garden where the first flowers don't just bloom but immediately scatter their seeds far beyond the fence. Something similar was happening in the young universe.

In the deep field of JWST, among thousands of galaxies, astronomers zoomed in on the source JADES-GS 209777 – and saw a cosmic chick. Its "shell" is a thick cocoon of gas and cosmic dust that long hid the growing black hole at its center. But at a redshift of 3,711 (1,8 billion years after the Big Bang), the shell began to crack.
