Destroy the space telescope in which more worlds were found



Although in 1995, When the first extrasolar planet was confirmed around the star, starting from 2009. With the advent of the Kepler telescope, the findings have increased sharply.

In his mission he authorized the confirmation of 2681 worlds, and around 2,900 are waiting for confirmation.

Kepler will not look for more planets. After nine years of work, he ran out of fuel, confirmed NASA and would remain in orbit far away from Earth.

Limitation with which it was calculated, in contrast to the accident he suffered in 2013, When one of his gyroscopes failed and forced to modify the area of ​​observation, although it remained active.

He discovered worlds like Kepler-186f (a name derived from the numerical order of the observed star), a planet the size of the Earth in a habitable zone, or Kepler-22b, a body between the size of our planet and Neptune, one that does not exist in the solar system.

"Like NASA's first planetary mission, Kepler surpassed all expectations in the search for life in the solar system and beyond," he says. Thomas Zurbuchen, deputy director of the agency in Washington.

In other words, this telescope has changed the vision of the cosmos: when you look at the night, the infinite twinkling points of the star, 3 to 5 out of 10 have a planet probably small, rocky and in a residential zone where liquid water can be.

Launched in March 2009 aboard the Delta II rocket, for four years explored a small area of ​​the sky, about 150,000 stars between the constellations of Cygnus and Lira, in search of very small fluctuations in the light of the stars that suggested the presence of a planet that went before its home star .

It is a transit method, one of the methods used to detect planets.

When the gyroscope failed, the mission was redirected to a celestial patch aligned with the plane of the solar system in which the planets revolve.

He added about 500,000 observed stars.

Finding so many in this small area of ​​blue and only one method suggests that the galaxy, in which there are over 100,000 million stars, is very abundant.

After finding the star's brightness drop, astronomers study the information to see if it is from a possible planet. This is confirmation. And while the whole volume of information is analyzed, the others remain awaiting confirmation.

The data shows that the most common planet is not the size of any of the solar system. It is larger than Earth and smaller than Neptune.

This is not the only novelty. Unbelievable formations have been found, like several planets so close to their star that the internal solar system (reaching Mars) seems wide.

To cite another case, in December last year eight distant planets were discovered using artificial intelligence. Thus, on a continuous basis, the discoveries were presented.

In February 2014, 715 new planets were presented in one advertisement, four years after confirmation of the first ones detected by the telescope: five in the same star.

"Now we know that planets are everywhere." Kepler introduced us to a new course, full of promises to future generations to explore the galaxy, "he says. William Boruckiwho was the scientific director of the mission.

Less known was the contribution in two active fields of astronomy: supernovae and astroarcheology.

For example, in the first Ed Shayaastronomer, he remembered when he looked at Kepler's data and found that a 10% increase in the brightness of the galaxy. Yes, the telescope saw a supernova explosion, the ultimate event of a massive star. And although it may be a computer error, the analysis confirmed that it was an explosion.

Kepler unconsciously found over 20 supernovae, including one of the exotic class.

In astroarcheology, he brought in a lot of data on the shock of stars, stellar waves resulting from vibrations in these celestial bodies and which scientists use to extract information about them.

"Kepler's mission was based on an innovative project and it was very successful to do this kind of learning," he says Leslie LivesayDirector of Astronomy and Physics at Jet Propulsion Laboratory in NASA.

Despite the picture of the telescope, the cartridge does not end there. "This is not the end of the discovery, I am excited about discoveries that will continue with the data," he says. Jessie Dotson, NASA scientist

Astronomers will have years to continue to dig into the information that the telescope has provided over the course of nine years, and they should confirm the existence of thousands of candidates.

Kepler dies, but he lives.
