Audi introduced its concept car Audi AI: Trail at the IAA 2019. The car is special because it combines futuristic design with autonomous driving, electric mobility.
An amateur astronomer has discovered a strange comet that is the second of its kind yet detected. The discovery was found on August 30. The name of the Ukrainian amateur is Gennady Borisov. And now when astronomer detected the strange comet, named it as C/2019 Q4 (Borisov), and say that it is moving too fast for it to be captured by the sun’s gravity.
The object will be recognized as comet until astronomers’ confirmation.
According to nationalgeographic.com “Already, astronomers have detected that the object—which is probably a couple miles across—has a coma, the fuzzy sheath of dust and gas that forms as sunlight heats up a comet’s icy surface”.
“This is the first highly active object that we’ve seen coming in from something that formed around another star,” says Michele Bannister, an astronomer at Queen’s University Belfast.
“What’s really fantastic is that this thing should be observable for a year,” says Matthew Holman, interim director of the International Astronomical Union’s Minor Planet Center, which issued the verification of C/2019 Q4’s path through space Wednesday evening.
“We get to see one little bit of another solar system,” he adds, “and without necessarily knowing which one it came from, that’s exciting.”
According to scientists the C/2019 Q4 is bigger and brighter which allows astronomers to collect its light and tease out chemical clues. We have some topics about the object of Oumuamua (learn more here), so astronomers discovered Oumuamua only on its way out of the solar system—but C/2019 Q4 is still inbound. It will make its closest approach to the sun on December 7, and it will come closest to Earth, within 180 million miles, on December 29.
“That’s why we say that gravitational perturbations are almost impossible,” Ye says.
