A black hole just obliterated a massive star and unleashed 400 BILLION times the Sun's energy, flinging a helium cloud toward us at insane speed. Tidal disruption events are pure cosmic violence and I am SO here for it 🔥🕳️

A rivet in my shutter door in my workshop is a perfect pinhole camera. At certain times of day I get a focussed sun image.

Ganymede Global Geologic Map and Global Image Mosaic

To present the best information in a single view of Jupiter moon Ganymede, a global image mosaic was assembled, incorporating the best available imagery from NASA Voyager 1 and 2 spacecraft and NASA Galileo spacecraft.

On eclipse day 2026, 193,000 visitors hit our site, peaking at 5,343 at once — just one Node.js process on a lone VPS. It bent; it didn't break.

Now, our eclipse hub is ready for events through 2029, driving anticipation for Luxor's 2027 totality.

We're already tracking 29,395 objects in orbit today, preparing for the next cosmic event.

A "born-again" star is a dead star, typically on its way to becoming a white dwarf, that temporarily re-ignites due to a rare late thermal pulse and resumes active evolution.

I am happier with this version of the North America Nebula, but the stars are a bit big, and there is a weird moiré pattern creeping into the shadow areas. Dammit this is hard.

Europa During Voyager 2 Closest Approach

This color image of the Jovian moon Europa was acquired by NASA Voyager 2 during its close encounter on Jul. 9, 1979. Europa, the size of our moon, is thought to have a crust of ice perhaps 100 kilometers thick which overlies the silicate crust. The complex array of streaks indicate that the crust has been fractured and filled by...
