Unusual observations in astronomy, geology, physics and the environment, including cases resolved through careful measurement and replication.
Scientific Anomalies & Natural Phenomena
FRBs are established astrophysical events, not unexplained transmissions in the colloquial sense. Magnetars can produce them, while the population’s diversity and emission physics remain active research questions.
Scientific Anomalies & Natural Phenomena
Blood Falls is visually uncanny but scientifically explained. Its colour comes from iron oxidation, while its isolated salty ecosystem remains valuable for studying life beneath ice.
Scientific Anomalies & Natural Phenomena
The anomaly was a real navigation residual, not an invented effect. Uneven radiation of onboard heat matched its magnitude and evolution, leaving no statistically significant anomalous acceleration.
Scientific Anomalies & Natural Phenomena
Ball lightning is a label for rare luminous events reported near thunderstorms. Instrumental observations constrain some cases, while varied testimony and competing physical models leave its full scope unresolved.
Scientific Anomalies & Natural Phenomena
Tabby’s Star is a genuine astronomical anomaly discovered through citizen science. Chromatic dimming supports small-particle dust rather than an opaque alien structure, while the dust’s origin remains unsettled.
Scientific Anomalies & Natural Phenomena
A source-led guide to anomalous signals, from underwater sounds to radio bursts: how calibration, reference libraries and independent repetition separate useful evidence from compelling noise.
Scientific Anomalies & Natural Phenomena
Cold fusion became a lesson in calorimetry, press-first science and replication. Later reviews left room to investigate materials effects but did not validate the original nuclear-energy claim.
Scientific Anomalies & Natural Phenomena
The Bloop was a real hydrophone recording, but not evidence of a giant animal. NOAA’s later Antarctic observations identified the same sound family in large icequakes.
Scientific Anomalies & Natural Phenomena
The Marfa Lights combine a modern roadside observation problem with older local folklore. Headlights and atmospheric effects explain much of the repeatable display without resolving every anecdote.
Scientific Anomalies & Natural Phenomena
The Kentucky Meat Shower was a documented fall of animal tissue, not weather creating meat. Conflicting identifications and absent surviving evidence leave the source probable rather than certain.
Scientific Anomalies & Natural Phenomena
The Lake Nyos disaster was caused by a limnic eruption: deep water saturated with volcanic carbon dioxide overturned and released a dense, suffocating cloud.
Scientific Anomalies & Natural Phenomena
Vela 6911 detected an unexplained double flash on 22 September 1979. Official and scientific assessments disagreed over whether it marked a secret atmospheric nuclear test.
