news Physics Evidence status: Peer reviewed · Single experiment
A laser-trapped quantum gas on China's space station spread so slowly over 7 seconds that it equals 9.7 picokelvin. What that record means, and what it doesn't.
news Astronomy Evidence status: Peer reviewed · Orbital observations
ExoMars TGO found hydrogen chloride over Alba Mons in the cold season, above fresh fissures. It may be magma seeping out, but no eruption has been seen.
news Astronomy Evidence status: Official announcement
NASA's Swift observatory re-entered over North Sumatra on 4 Nov 2026 after almost 22 years. Why drag won, what Swift found, and what is unknown about debris.
explainer Earth
Earth's mass is about 5.972 × 10²⁴ kg (13.2 septillion lb). See how scientists calculate it from orbits and G, why G limits precision, and the maths.
news Astronomy Evidence status: Peer reviewed · Method paper
A Nature study's FLIP software recovered the known planet 51 Eridani b in JWST data at 4.3 microns and beat standard processing 2 to 15 times. No new planet.
news Astronomy Evidence status: Peer reviewed · Observational census
A census of 37 nearby dwarf galaxies finds they keep 4% to 25% of the oxygen their stars made, about 11% on average. Where the rest went is still unknown.
news Astronomy Evidence status: Peer reviewed · Observational study
A white dwarf has two separate gas rings. Astronomers propose two surviving planetary bodies, up to Pluto-sized, make the gas. Neither body has been seen.
news Astronomy Evidence status: Peer reviewed · Single galaxy
JWST spots a barred spiral galaxy seen 1.1 billion years after the Big Bang, with a bar nearly as long as the Milky Way's. Peer reviewed, but still a candidate.
news Astronomy Evidence status: Official announcement · Preprint
Rubin Observatory's first dwarf-planet candidate, 2026 ED138, orbits beyond Pluto about 47 au out. Its 612 to 1,530 km size rests on an unmeasured albedo.
