July 16: Nukes, Nintendo-Level Jupiter Fireworks & Mozart Sass

July 16 is one of those dates that just refuses to be boring. We've got literal cosmic explosions, an emperor with strong opinions about note counts, and a Nigerian superstar who shares his birthday with a comet crashing into a planet. Buckle up.

The Sky Really Overachieved Today

In 1994, fragments of Comet Shoemaker–Levy 9 began slamming into Jupiter, with the first impact producing a fireball that hit a peak temperature of 24,000 kelvin. That's roughly four times hotter than the surface of the Sun, and infinitely hotter than any take you'll read online today. Meanwhile, back in 1945, the United States conducted the first-ever detonation of a nuclear weapon in the Trinity test. Between Jupiter and New Mexico, July 16 clearly has a thing for very large, very bright, very concerning flashes of light.

Mozart, Chicago, and George Washington's Real Estate Deal

In 1782, Mozart's opera Die Entführung aus dem Serail premiered in Vienna, after which Emperor Joseph II reportedly sniffed that it had "too many notes." Imagine being one of history's greatest composers and getting the 18th-century equivalent of "it's giving too much." In 1790, President George Washington signed the Residence Act, picking a spot along the Potomac that would eventually become Washington, D.C. — arguably the most consequential rooftop-adjacent parcel of land in American history. Speaking of rooftops: in 2004, Chicago's Millennium Park opened as one of the world's largest rooftop gardens, giving tourists a reflective bean to take 40 million selfies in front of.

The Birthday Squad Is Stacked

Today's birthday lineup is genuinely loaded. Nigerian megastar Wizkid was born in 1990, the same day as Big Time Rush's James Maslow — a crossover concert we didn't know we needed. Also blowing out candles: Australian heartthrob Luke Hemmings of 5 Seconds of Summer (1996), rapper and Brockhampton mastermind Kevin Abstract (1996), and actress Alexandra Shipp (1991). Jamaican sprinter Shericka Jackson (1994) rounds out a group that could, collectively, out-talent an entire awards show. If you're born on July 16, the universe basically handed you a backstage pass.

A Holiday for the People Who Build Everything

Over in Honduras, July 16 is Engineer's Day — a genuine celebration of the folks who make sure bridges stay bridge-shaped and buildings stay building-shaped. Given that today's history includes nuclear tests and a comet demolishing a planet, honoring the people who calculate load-bearing structures feels deeply appropriate. Raise a protractor. Also observed today is Our Lady of Mount Carmel, marked by the vibrant Fiesta de La Tirana in Chile's Tarapacá Region, where dancing and devotion collide in glorious color.

So there you have it: July 16, a day that fires on all cylinders — some of them literally.
