Space:
Every once in a while, something appears in the sky that attracts the attention of even those who normally don’t bother looking up.
It’s likely to be that way on Saturday (July 5), when the waxing gibbous moon — 58 percent illuminated and just past first quarter phase — will appear in very close proximity to Mars. People who are unaware or have no advance notice will almost certainly wonder, as they cast a casual glance toward the moon on this night, just what is that orange-yellow "star" hovering just above it?
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.
