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.
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 · Statistical analysis of two real events
Two gravitational-wave events and a galaxy catalogue give H0 = 67 (+18/−15) km/s/Mpc, a first for this method, but too imprecise to settle the Hubble tension.
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.
news Astronomy Evidence status: Peer reviewed · Laboratory analysis of one meteorite
Teghaza 001, an 800 g Sahara meteorite, formed at least 4.1 billion years ago and samples Mars's early crust and a primordial mantle source, Science reports.
