HUBBLE-LEMAITRE LAW

The belgium priest Georges Lemaître (1894-1966) was one of the first to consider that the Universe began as a result of the explosion of a hyperdense singularity. The scientific community remained skeptical until two years later, when the american astronomer Edwin Hubble (1889-1953) observed that most galaxies are distancing themselves from ours.

HAVE YOU EVER HEARD ABOUT LAVA WORLDS?

It’s a class composed of terrestrial planets orbiting extremely close to their parent star, resulting in high internal heat and volcanic and  tectonic activity, creating lava lakes at the planet’s surface.

There are several hypotheses about its origin. Among them, there’s the possibility of an impact between large celestial objects or by the gravitational effect of its parent star, which causes intense irradiation and tidal forces.

THE ICE GIANTS

They are a class of planets composed mainly of heavier elements such as Oxygen, Carbon and Nitrogen, significantly not as small as terrestrial planets, but not as big as Gas Giants. There’s no need to search far to find them: Uranus and Neptune, both part of this type of planet, are located on our Solar System.
