NASA's legendary Kepler Space Telescope has withdrawn after exhausting the fuel needed for further scientific operations. This ended a nine-and-a-half-year mission that saw over 2,600 intriguing exoplanets, some of which may be housed. Life, the US Space Agency said.
Data collected by Kepler's space missions indicates that our skies are filled with billions of hidden planets – more than the stars, NASA said in a statement.
The Unmanned Space Telescope Founded in 2009, the US Space Agency leaves behind a legacy of more than 2,600 planetary discoveries outside our solar system, many of which could be promising to humans.
"As Kepler's first NASA mission, Kepler wildly surpassed all our expectations and paved the way for our exploration and search for life in the Solar System and beyond," said Thomas Zurbuchen, Deputy Administrator of NASA's Science Mission Directorate here.
"Not only that." How many planets we could have out there has sparked a whole new and robust field of research that has taken the scientific community by storm, "said Zurbuchen.
" His discoveries have shed new light He threw our place in the universe and illuminated the tantalizing secrets and possibilities under the stars, "he said.
Kepler has opened our eyes to the diversity of planets in our galaxy, mission scientists said.
The recent analysis of Kepler's discoveries is coming to conclude that 20 to 50 percent of the stars visible in the night sky are likely to have small, possibly rocky, planets whose size corresponds to Earth, and are in the habitable zone of their parent stars.
That is, they are in Distances from their mother stars, where there is liquid water ̵
The most abundant planet that Kepler found does not exist in our solar system – a world between the size of Earth and Neptune – and we have much to learn about these planets, according to the US Space Agency.
Kepler also found that nature often produces jammed planetary systems, in some cases so many planets orbiting around them see that our inner solar system is sparse by comparison.
"When we started to design this mission 35 years ago, we did not know a single planet outside our solar system," said the Kepler mission investigator. William Borucki, now retired from NASA's Ames Research Center.
"Now that we know that planets are everywhere, Kepler has taken us to a new course that is promising for future generations to explore our galaxy," said Borucki.
The Kepler Space Telescope, launched on March 6, 2009, combined cutting-edge techniques to measure the brightness of stars with the largest digital camera set up for space observations at that time.
Originally Positioned to Be Persistent When Kepler made 150,000 stars in a star-studded sky field in the constellation Cygnus, Kepler made the first survey of planets in our galaxy and became the agency's first mission to Earth-sized planets in the habitable zones of their planet To discover stars.  "The Kepler mission was based on a very innovative design and it was a very smart approach to this kind of science," said Leslie Livesay, director of astronomy and physics at NASA's Jet Propulsion Laboratory, who served as Kepler during mission development Project Manager was active.
"There were definitely challenges, but Kepler had an extremely talented team of scientists and engineers that had overcome them," said Livesay.
Four years after the mission, after the primary mission objectives had been achieved, mechanical failures temporarily halted the observations.
Develop a fix and change the spacecraft's field of vision about every three months.
This allowed for an expanded mission for the K2-designated spaceship, which lasted as long as the first mission and Kepler's number of stars studied increased to over 500,000.
Observing so many stars has allowed scientists to conduct and better understand the properties of stars. This is an important piece of information when studying the planets orbit them.
New research on stars with Kepler data is also driving other areas of astronomy, such as the history of our Milky Way and the early stages of exploding stars called supernovae, which are used to study the speed of the universe, NASA said.
The extended mission data was also made instantly available to the public and academia so that discoveries could be made at an unbelievable pace and set a high bar for other missions.
Scientists are expected a decade or more in search of new discoveries in the data resources provided by Kepler.
"We know the spacecraft's exit is not the end of Kepler's discoveries," said Jessie Dotson, Kepler's project scientist at NASA's Ames Research Center
Before leaving spacecraft, scientists have exhausted Kepler to the full Observation campaigns successfully completed and valuable scientific data downloaded even after launch warnings of low fuel consumption.
The latest data from Campaign 19 will complement the data from NASA's latest planet hunter, the Transiting Exoplanet Survey Satellite launched in April.
TESS builds on Kepler's foundation with new data sets His search for planets orbits about 200,000 of the world's brightest and nearest stars. Worlds that can later be explored for life signs by missions such as the NASA Space Telescope James Webb (19659029).
