Deep Field covers astronomy and cosmology. Telescopes and what they find, planets near and far, and the strange physics of the deep universe, traced back to the journal papers and observatory data behind the headlines.

When a climate cycle and a warming trend collide, oceans pay the price—and scientists worry about what comes next.

The deceptive calm before a hurricane hits reveals how radar and reality exist in different time zones.

When one ocean basin quiets down, another roars to life—forcing forecasters to cover two storm seasons simultaneously.

GRB 061201 was the textbook "hostless" burst. A team led from the Purple Mountain Observatory weighs two candidate galaxies against each other and finds the faint one wins on most tests, loses the formal chance-alignment score, and carries one loud caveat: its redshift is fitted rather than measured.

ALMA detected ionised oxygen in a galaxy seen before the universe was 300 million years old, supporting rapid stellar enrichment while leaving its exact history open.

The 2025 estimate depended on uncertain motions and neighbouring galaxies. A 2026 follow-up put the merger probability higher, showing why the forecast remains sensitive to the measurements.

For the first time, astronomers can map the cosmos in bulk, capturing the light signatures of a thousand distant objects at once to unlock the history of billions of galaxies.

The discovery challenges assumptions about how single-celled life reproduces, revealing a microbe that births generations within itself before explosive release.

An 1879 experiment to test the limits of seed longevity has become one of science's longest-running projects, with some seeds still viable after 142 years underground.

Webb spectra suggest Neptune’s inner moons were rebuilt from destroyed icy interiors, while separate evidence casts eccentric Nereid as a possible original survivor.

Cassini data reveal that tiny Enceladus drives a main and reflected Alfvén-wave system through Saturn’s magnetosphere for at least half a million kilometres.

A reanalysis suggests Voyager 2 encountered Uranus during rare solar-wind compression, temporarily shrinking the dayside magnetosphere and reshaping its plasma environment.
