There are almost one million asteroids and comets in our solar system. And every single one of them (we think) formed here, within our solar system, alongside the planets just over 4.5 billion years ago.

This object, now named ‘Oumuamua, was the first asteroid discovered from outside the solar system

The first exosolar planet (a planet orbiting a star other than the Sun) was discovered in 1995, and since then humans have found over 3600 planets outside of our solar system. Some of those found are orbiting not one star like we do, but two stars. For example, stars Kepler-35A and 35B orbit each other, but a planet Kepler-35b, orbits both of them. This is much more like the fantasy word Tatooine in the space epic Star Wars than our own planet Earth. In A New Hope, we see young Luke Skywalker

When you read a scientific story in a popular blog or magazine, many times you will see the caveat "artist interpretation" next to some of the accompanying images. This as a gross undersell of the time, effort, and most important, accuracy, that goes into developing the renders. While we don't know what a black hole or an exoplanet looks like, it is important to attempt to visualize them, and to do it as accurately as possible. This video is an interview with two people who are responsible for

This achievement not only firmly set the Soviet Union has the leader in space technology at the time, but marked the beginning of the human exploration of space.
