Scientists have used radio waves to precisely measure Venus' spin rate and tilt on its axis. We knew the Venus day was exceedingly long, but now we know that the length of a day on Venus regularly changes in length!

In May 2019, astronomers measured the largest flare ever from Proxima Centauri, the closest star to our sun. What do such flares mean for possible alien life, on a planet in the Proxima Centauri system, only 4 light-years away?

In 2018, a small asteroid crashed into Earth, and scientists recovered pieces of it in a Botswana game reserve. Now the scientists have determined the space rock's origin: Vesta, in the asteroid belt.

Astronomers have managed to detect very long wavelength radio emission from a well-studied, repeating fast radio burst, called FRB 20180916B. What's more, the longer wavelengths arrive 3 days after the shorter wavelength counterpart of the signal! Why?

NASA has released a cool new visualization showing two massive black holes orbiting each other in a stunning display of light. The intense gravity and other phenomena all play a part in producing this mesmerizing display. Watch here.

Follow the action as asteroid scientists, space agencies and civil protection organizations participate in a drill - simulating an asteroid impact about to happen - during this week's virtual Planetary Defense Conference.

Dust shed from comets and asteroids constantly rains down on our planet. How much of this extraterrestrial material lands on Earth’s surface?

NASA's Parker Solar Probe, currently studying the sun, has observed the entire dust ring that encircles the sun along Venus' orbit. It is the first complete view of this dust band from any spacecraft.

Astronomers saw Proxima Centauri - the star nearest our sun - emit a flare, or burst of radiation, 100 times more powerful than flares from our sun. They said Proxima's flare ranks as one of the most violent seen on a solitary star anywhere in the galaxy.

The launch of Crew-2, the 2nd flight of this particular Crew Dragon, went off without a hitch Friday morning, after being postponed due to weather.
