Five years of FAST timing weighed PSR J1856-0039 at 2.488 solar masses. Its merger should leave a neutron star, not a black hole. The math is inside.

Mars orbits inside the Sun's habitable zone and still freezes. We work out the zone's edges for any star, and the dates when Earth falls out of it.

A 7-second wobble in a pulsing star hints at a giant in the habitable zone of a star nine times brighter than the Sun. We check its 51% odds inside.

Most shooting stars are comet dust smaller than a grain of sand, burning up 100 km above you. Hear how a meteor shower works in Episode 18, free.

Saturn at opposition, two meteor showers and a Moon over the Pleiades: October 2026's sky events timed against moonlight, with the clocks converted.

New 2026 simulations: a hot but solid Theia split and left an intact Moon in hours, a cold one only debris. The run-by-run numbers are inside.

Starship Flight 14 reached orbit and released 26 Starlink V3 satellites, then came home after one lap, not six. We put the whole day on one clock.

Cutting warming to 1.5C instead of 3 would avoid 11,600 US wildfire-smoke deaths a year. Four studies price each defense, and the math is inside.

Mouse lineage tracing and human stem cells put the hindbrain on its own track from the start. The 494-cluster count the coverage skipped is inside.

MIT's 40-page report names cognitive surrender once and never counts it. We ran the numbers: at least two undergraduates in three use AI and fear it.

Webb found nine brown dwarfs in IC 348 down to 2 Jupiter masses, and eight carry a hydrocarbon no model predicted. What class H breaks is inside

Six months outside the ISS damaged 19 of 61 eye lenses, six in a way no one can explain. Nobody can operate in space yet, and a Moon base has a date.

You were handed a paradox. Physics has an inequality instead, a ceiling of one and a measured 0.97. The algebra and the missing 3% are inside.

A germanium crystal under 1.4 km of rock saw nothing for 62 days. That silence pushed one number to 4.64 m and killed the model. The math is inside.

Gaia's next release should push parallax to 10,000 parsecs, past the 8,275-parsec Galactic center. The whole distance ladder is inside, rung by rung.

A 7 eV electron crosses a 1 nm wall 7 times in 100 million, and the Sun runs on odds like that. The formula, four widths and a 2021 error fixed.

LRO found a 222-meter crater from spring 2024, the largest fresh one known. Its energy implies a 7-meter rock, not six stories, and the math is here.

BepiColombo let go of its transfer module 200 million km out. Light explains only 11 of the 112 minutes Earth waited. The full timeline is inside.

Ten thousand AI agents proved a fluid can hit infinite speed in 88 hours. The catch is the force pushing it, and the real question is still open.

Super El Niño raises heat, drought and flood risks into 2027. Explore the WMO forecasts, historical disasters and what the climate evidence shows.

The ongoing quest to understand the absolute limits of solar activity has led researchers to reevaluate historical archives and stellar analogs

A 35,000-solar-mass black hole in UGCA 320 feeds on gas that, due to its own motion, piles up behind it. We ran the radius the paper skipped; the caveat is inside.

Andromeda's 301 km/s approach, a planet weighed from a 59 m/s wobble, and a galaxy whose redshift gives 14 times light speed: four formulas inside.

Tidal stretch at a black hole's horizon falls as the square of its mass. We ran the numbers: the survival line sits near 4,600 suns, not a billion.

A black hole's ringdown shifts twice, and the gap between the two shifts tests the matter around it. Two models, 12.5 times apart, worked inside.

Light in water crawls at 225,000 km/s, so an electron passes it and glows. The cone opens to 41.4 degrees, and the whole photon count is inside.

You were taught it's the redshift. It isn't. Expansion buys a factor of 1.7, the galaxies' age buys a million billion, and the sums are inside.

Your calendar says autumn. The thermometer says August. Three sources explain the 22 days before the equinox, and only one of them explains the rule.

Recent observations reveal that the supermassive black hole in NGC 1275 emitted an X-ray flare, followed by its powerful radio jets approximately 300 days later

Recent research led by Shi-Liang Zhu demonstrates the first direct laboratory test of Richard Feynman's eighty-year-old quantum path-integral concept using single particles of light

Webb read the Galactic center's brightest infrared star and found silicate dust, not carbon. A 2008 reading was wrong, and the arithmetic is inside.

NASA's own numbers settle it: one Roman image spans about 200 Hubble infrared frames. The same mirror, remade for surveys, and the woman it honors.

Foreshocks preceded 71 of 77 fracking earthquakes in western Canada. Raise the bar to magnitude 2 and about 23 gave no warning. Arithmetic inside.

The USGS reported a magnitude 4.4 quake in Nepal on 26 August 2026, then withdrew it. A glacier collapse made the signal, and the catalog entry shows how.

Quantum teleportation moves a quantum state, not matter. Why two classical bits keep it slower than light, and why the fiber record is still 100 km.
