A telescope under an open dome. You can see stars outside. In front of the telescope, there is a desk with buttons, switches and lights.

In 1967, astronomers at the Observatoire de Haute-Provence in the south of France discovered potassium flashes while they were observing stars. But the laws of physics that were known at the time didn’t provide any explanation as to how a star could produce these flashes. Were there aliens trying to communicate with us?

So in a way, he is painted to be this visionary genius who made it possible for Europeans to arrive on a new continent.

A green pea galaxy imaged by the Hubble Space Telescope. NASA.

There is a kind of small, compact galaxy in which many stars are forming. They are one tenth of the size of our own Milky Way Galaxy, and one hundred times more compact. They are called green pea galaxies.

Pluto seen by New Horizons

Since the early 20th century, the International Astronomical Union or IAU – an organization that brings together astronomers from around the world – defines the names used by astronomers to talk about objects in the Solar System. In August 2006, the IAU decided a planet is an object that
