The 5 great triumphs of Kepler
The 5 great triumphs of Kepler
The most outstanding scientific results of the Kepler telescope.
One of the most important spatial devices in history, the explorer who changed our vision of the Universe forever and the place we occupy in it, is now history. It will remain in its orbit around the Sun for an indefinite time, perhaps to the very end of the Solar System, as a relic of past times, while everything it achieved in those 9 years of activity make up a treasure that will continue to extract new findings for decades, in addition to marking the path that others will follow later.
List the discoveries of Kepler It would be an endless task, since it holds almost 3,000 confirmed exploplets. But it is just as enlightening to gather all of them into 5 categories, which exemplify much more clearly the milestones of this mission, and in which fields of knowledge changed what we thought we knew.
1) More planets than stars: When it was released, only a few planets were known in other stars. They continued to be seen as something exceptional, a cosmic rarity. Everything changed with its first findings, which soon grew exponentially, until it clearly demonstrated that far from that particularity, and extrapolating the data to the entire galaxy, we can have some assurance that they are more abundant than the stars themselves.
2) Small planets are common: As it is logical, the first findings of exoplanets were always huge bodies, as big or bigger than Jupiter, and there was the idea that perhaps that was the norm, being the small and rocky like ours an exception. Again Kepler proved the opposite: The Galaxy is full of Earth-sized worlds, and many of them may be similar to the land in size and distance of its progenitor stars.
3) They are diverse: The above leads to this point. The planets are varied, even more than we can see in the Solar System, since the most found Kepler it's a kind of world, halfway between Neptune Y the earth, that does not exist in our planet system. It was clear how much we had left to learn.
4) And planetary systems too !: While
our own inner Solar System has four planets, Kepler
found systems with considerably more planets, up to eight, in
Orbit near its progenitor stars. The existence
of these compact systems raises questions about how they are formed. Are they born close to their parent star, or
they form further and migrate inward? Again as many answers as questions.
5) New knowledge revealed about the stars:
In addition to throwing ourselves into the golden age of exoplanets, Kepler revitalized the study of the stars. He observed more than half a million stars, which was essential for understanding the basic properties of the planets that orbit them, and they are improving our understanding of the history and structure of our galaxy and the universe.
In particular, Kepler It has captured the initial stages of supernovas, with unprecedented precision, which gives us a new understanding of how these stellar explosions begin.
