The oldest light there is — released 380,000 years after the Big Bang, stretched over 13.8 billion years into microwaves. Tiny temperature ripples, one part in 100,000, are the seeds every galaxy you passed grew from.
The supermassive black hole at the centre of our galaxy — four million Suns inside a sphere you could fit within Mercury's orbit. Shown here with real ray-traced light-bending: the glowing disk behind it is wrapped over the top and under the bottom by gravity, the way Kip Thorne's equations bent it for Interstellar's Gargantua.
Our galaxy and Andromeda are falling toward each other at ~110 km/s. They will sweep through one another, fling out long tidal tails, fall back, and after several passes merge into a single elliptical galaxy — sometimes nicknamed “Milkomeda”.
From a city-sized neutron star to a hypergiant that would swallow Saturn — every star here is drawn to true relative size on a logarithmic scale, tinted by its real blackbody colour. Drag to look around.
