APM 08279+5255: The Lensed Quasar, a Monster Black Hole, and the Universe’s Water Reservoir
We dive into APM 08279+5255, a gravitationally lensed quasar from the universe’s youth. Learn how a foreground galaxy magnifies its light by about four times (not the initial 40–90x) thanks to Hubble imaging that revealed three distinct images. Meet a supermassive black hole of roughly 10–23 billion solar masses tucked in a massive, infrared-luminous galaxy, seen almost face-on. And hear about the universe’s largest single mass of water detected so far—about 100 trillion times Earth’s oceans—...

The Scarecrow Theorem: Geometry, Gaffes, and Pop Culture
We dissect the Wizard of Oz diploma moment where the scarecrow declares a formula for an isosceles triangle that fails on three counts: wrong shape (not necessarily a right triangle), wrong operation (square roots vs squares), and the wrong relation between sides. We explain why Pythagoras only applies to right triangles, why the 'any two sides' setup collapses under the triangle inequality, and how the gag echoed in pop culture (The Simpsons). It's a meditation on confidence versus real unde...

Feeding Time for an Ancient White Dwarf: The Case of LSPM J0207+3331
In this deep-dive, a Backyard Worlds citizen-science discovery reveals an ancient white dwarf, LSPM J0207+3331, that’s actively accreting the metal-rich core of a large, dry rocky body. Its atmosphere hosts 13 heavy elements—the most ever seen in this type of star—while a close-in silicate debris disk challenges models of planetary-system longevity. Ongoing accretion is confirmed by strontium, and hints of calcium emission suggest magnetic or heating processes we don’t yet understand. A dynam...

WASP-18b: The Planet on a Million-Year Countdown
We dive into WASP-18b, an ultra-hot Jupiter with a mass around ten Jupiters that orbits its star in roughly 1.9 days and skims about 0.02 AU. Its fate is to spiral into its star in under a million years. We unpack why the planet is so extreme—tidal decay, dayside temperatures near 3,000 K, and the atmospheric puzzles JWST helped reveal—including two distinct thermal regions and the fate of its water vapor. Then we explore what this means for tidal physics, planetary atmospheres, and our broad...
