Webb reveals giant planets must form before their nurseries empty
Webb mapped molecular winds, atomic winds and jets across 72 planet-forming discs, tracing how the gas reservoir needed by giant planets changes with age.
Astronomy and cosmology
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.

Rubin can test Planet Nine by finding the world directly or determining whether the distant orbital patterns survive in an independent survey.

Venus combines ocean-depth pressure with furnace heat, but its supercritical carbon-dioxide atmosphere is stranger than either comparison suggests.

A random-forest classifier distilled simulated planetary architectures into a 44-system observing shortlist, but its 99% precision was measured only inside the synthetic universe used to train it.

LHCb's most comprehensive analysis of the rare B0 to K*0 muon-pair decay preserves a decade-old tension with the Standard Model, but difficult hadronic effects and the sub-five-sigma significance still rule out a discovery claim.

A 2026 preprint models SpaceX’s filed million-satellite orbital data-centre system and finds that its assumed 800 m² spacecraft could dominate the naked-eye sky at many times.

Roman will test the Hubble tension through supernovae, gravitational time delays, galaxy clustering and the growth of cosmic structure.

Sagittarius B2’s ethyl formate and G34.3’s ethanol were identified through molecular spectra. The drinks comparisons are memorable, but both compounds occur only as traces.

MESSENGER mapped glacier-like runouts and hollows in two Mercury craters; salt-flow models explain their form and longevity, but neither composition nor habitability has been demonstrated.

NASA climate simulations keep an assumed early Venus ocean temperate for almost three billion years, but competing models and atmospheric chemistry challenge whether that ocean ever formed.

Conductive rods made from Martian materials could warm the planet efficiently in climate models, but a decade-long particle lifetime and planet-scale production remain assumptions.

NIRSpec found a water-shaped transit signal at GJ 486 b, but two MIRI eclipses measured a nearly bare-rock dayside, making cool stellar patches the stronger explanation.

Zhurong radar layers and backwater geometry in nine Aeolis Dorsa channel belts provide separate evidence for a large ancient body of water in Mars’s northern lowlands.

A NASA-led Nature analysis found that measurement uncertainty probably created the apparent ceiling in Earth's polar geomagnetic response; after calibration, the response remained linear.

Curiosity’s hand-sized polygons resemble ancient wet-dry cracks elsewhere in Gale Crater, but NASA is testing several other origins before assigning this vast fracture field a water history.

NASA Deep Space Network logs show that a distant observer on the Earth–Mars line would have occupied one of humanity's Martian uplink beams 77 percent of the time from 2005 through 2024.
