Galaxy Simulation
Watch galaxies collide in a particle simulation. Each dot represents millions of stars. See how gravity pulls spiral arms apart and reshapes galaxies over billi
Black Hole Physics
Explore what happens near a black hole. See light bend around the event horizon through gravitational lensing. Learn about spaghettification, time dilation, and
Exoplanet Hunters
Detect planets around distant stars using the transit method. Watch the light curve dip as a planet passes in front of its star. Measure the dip to calculate th
