For several years, astronomers have known that rings of dust follow the planets Earth and Venus in their journeys around the Sun. Researchers have now found a similar ring of dust also accompanies Mercury in its orbit, much to the surprise of astronomers, who believed any system like this would be driven away by the Sun. Our own ring is produced by collisions between bodies in the asteroid belt between Mars and Jupiter, but computer simulations have shown the ring bonded with Venus is likely the result of a previously-unknown asteroid belt around the orbit of that planet.Read More What a Dusty Solar System We Have! Here’s What Astronomers Found Hiding in the Mess
The Parker Solar Probe became the fastest spacecraft in history on October 29, as it came closer to the Sun than any other vehicle. The spacecraft reached speeds of nearly 247,000 kilometers per hour, or more than 153,000 miles per hour, faster than any other man-made object. Parker also came within 42.7 million kilometers or 26.6 million miles, of our stellar companion. The spacecraft was launched on August 12th 2018.Read More Parker Solar Probe Flies Faster and Closer to the Sun than Any Previous Mission
