This surreal phenomenon called Lāhainā Noon, also known as a zero‑shadow day, happens twice a year in Hawaii when the Sun passes directly overhead at solar noon, causing vertical objects to cast no visible shadow.

This is what the sky from Earth might look like if TON 618, the second largest known black hole in the universe, were as close as Alpha Centauri, the closest stellar system to our Solar System. That's 25 trillion miles away from us.

I asked Fable 5 to make a universe simulator from Earth to the Milky Way all the way up to the observable universe. It used real NASA + ESA data to build out our solar system with every planet and many moons, nearby star systems, and dozens of real exoplanets. Click any star or planet to fly to it and see its info or zoom onto its surface.

Stephenson 2-18, the biggest mf star in the known Universe. Larger than UY Scuti, Antares, Vy Canis Majoris, you name it. 🤩 The estimated radius is about 2,150 times that of the Sun, and the volume is 10 billion Suns. If Stephenson 2-18 replaced the Sun in the solar system, its photosphere would extend beyond the orbit of Saturn. It would take earth’s fastest jet over 500 years to travel around. It would take almost 9 hours at the speed of light. Data from @planets_education.org Video from / tiktok / spacenstuff
