The Farthest Known Object in Our Solar System is Pink

Nicknamed Farout (but formally known as 2018 VG18) a pink-hued space object has been discovered orbiting the sun. It’s 22 billion miles further away than the second-most distant known object—and it takes more than 1000 years to complete an orbit. Not much else is known except that it’s roughly 310 miles across and spherical. Read more about the dwarf planet, its discovery and how it …

The Fastest Spacecraft Ever, NASA’s Parker Space Probe

The fastest manmade object ever, NASA’s Parker Space Probe, hurtled toward our Sun at 700,000 kilometers per hour. Its mission: to learn about particle and solar wind acceleration in the Sun’s corona, its shifting outer layer of plasma. It was launched in August 2018 and had to overcome many obstacles even before takeoff—including weight, size, and preparation for radiation and acute variation in temperature. Watch the “Science …

The way the object sped up as it passed the sun has researchers most puzzled. “Lightsails,” the solar-powered starships that Breakthrough Starshot plans …
