Evolution of Pluto over the years

Some are sharing on social networks meme Our knowledge of Pluto has undergone impressive evolution over the years.

Until 1930, no one knew the stone existed in the outer reaches of the solar system. It’s impossible to observe with the naked eye, and it’s so distant that no one noticed Pluto until the 20th century.

In 1930, through telescopes on Earth’s ground, Pluto was just a tiny blip in a sea of ​​other points.

Charon was discovered in 1978. After all, point Pluto has a partner. Observing through ground-based telescopes, Charon turned out to be normal.

In 1994, the Hubble Space Telescope found Pluto to be a fuzzy spot.
That same year, two diffuse objects (Pluto and Charon) could be photographed simultaneously using the same telescope.

In 2005/2006, the Hubble Space Telescope observed other moons in the Pluto system. Yes, Pluto became a “system” with a set of moons following the Pluto lord.

The same telescope observes this amazing system from time to time.

In 2010 (not 2013), multiple Hubble Space Telescope images of Pluto were merged to create an image of Pluto’s surface.
This image, taken using a computer program, appears to show a smooth surface, like seeing Pluto from a distance.

In 2015, explore new horizons Passing through the Pluto system suddenly opens up a whole new world to us.

Pluto is now known:
– Have at least 5 satellites in your mini system.
– Possibly a binary system (with Charon).
– There is a thin atmosphere consisting of nitrogen/nitrogen, methane and carbon monoxide from the surface.
– Its surface has heart-shaped “sputnik plains” containing dunes (where the sand is made of solid methane ice): This methane ice surface could be interesting for astronaut skiers.
– The other hemisphere of Pluto has more nitrogen/nitrogen and carbon monoxide ices.
– Most likely on their surface there are ice volcanoes – ice volcanoes.
— and it may have an inner ocean: beneath its surface is an ocean of liquid water.

through the amazing universe

So nothing has changed on Pluto since 1930.
But for us, a big change! In less than 100 years, our understanding of this outer solar system object has changed dramatically.

Diffuse and inconsequential points that are far away turn out to be surprising: with unimaginable dynamics.

It is now known that the Pluto system is far more complex than previously thought.
Pluto has an amazing variety of points of interest on its surface, below its surface, and near it.

In Spock’s words, Pluto has become enchanting!
