9. Juno space mission is the first Solar powered spacecraft to travel near Jupiter. Juno space mission sets the record by surpassing the distance of Rosetta spacecraft by European Space Agency.
8. Mangalyaan or Mars Orbiter Mission is the first spacecraft to orbit Mars in it's first attempt.

7. The first theory positing the existence of black holes was from an English clergyman named John Michell in November 1784. He even correctly noted that these features would not be visible to the naked eye, but that they could be detected by their gravitational effects on other bodies.
6. Despite proving through General Relativity that black holes could form, Einstein himself did not believe they could form in the natural world. It wouldn't be until 1972 that Cygnus X-1 became the first observed black hole.
5. In 2002 astronomers presented evidence that a supermassive black hole lurks at the center of our Milky Way.
4. In 2012 Suvi Gezari and his team published the first visual evidence of a black hole. Using the Pan-STARRS 1 telescope in Hawaii, they photographed a supermassive black hole 2.7 million light years away swallowing a red giant.
3. In 2015 gravity waves from the merging of a pair of black holes into one were detected. The violence of their merging created a ripple through space-time that was detectable here on Earth millions of light years away.
2. Not only did general relativity predict that black holes were possible, but it also predicted that white holes could also be possible. The polar opposite of a black hole, a white hole is a region of space-time where matter cannot enter.
1. A growing theory suggests that white holes are the opposite ends of black holes, and that our own Big Bang was a supermassive white hole that existed for fractions of a second.
