China made history earlier this month with the first successful soft landing on the far side of the moon — and now, the mission has sent back an incredible panorama view of its work site.
It's time to say goodbye to one of the most storied explorers of our age: Voyager 2 has entered interstellar space.
NASA is starting scientific observations of a new asteroid called Bennu today (Dec. 3), kicking the OSIRIS-REx mission into full gear.
The moon is pretty enough here from Earth, but it's even more stunning up close, as this new image from NASA reminds us.
Going, going — nope, it's still just going, NASA says of its Voyager 2 probe, which the agency realized was approaching the edge of the solar system back in early October.
Earth hides its scars well; the planet has endured countless millennia of eruptions and collisions, but scientists are still stumbling upon the evidence of all that geologic drama.
Ever since astronomers first spotted their first-ever object from beyond our solar system, it has offered more questions than answers — what is it? Where did it come from? Why is it so darn weird?
A pair of tiny Japanese robots sent back wild images once they successfully landed on their new home, the asteroid Ryugu.
