A new study gives the first evidence that exoplanets exist beyond the Milky Way.
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.
While interesting purely out of curiosity, what possible use can we get out of that? Even if the observers are completely accurate, they're looking hundreds of thousands, or millions of years into the past. What they see hasn't been where they see it since before the dawn of humanity. And we couldn't reach it within the lifespan of our species.
