An unmanned NASA spacecraft hurtling into the unknown will make a close shave past Pluto on Tuesday, offering scientists a close glimpse of the dwarf planet's surface for the first time.
But there were some jitters Monday as the $700 million spacecraft, called New Horizons, sped toward the last undiscovered frontier in the solar system.
The supermassive black hole is 40 million times as massive as the sun and powers a quasar that existed 700 million years after the Big Bang.
The asteroid zoomed by Earth at a perfectly safe distance of around 1.8 million miles (2.9 kilometers).
Images show surprise changes to the spacecraft as it interacted with the atmosphere.
