The end of an era. The famous NASA space Kepler telescope spends almost a decade collecting information about the existence of thousands of planets and sent wonderful images of our visible universe.

The NASA space telescopes Kepler ran out of fuel more than nine and half years after its launch and will now retire in a safe orbit around the sun, the NASA announced on Tuesday in a press conference.
It was known that the observatory’s hydrazine supply was running out over the past few months, however, the controllers noticed a dramatic drop in fuel pressure earlier this month, which indicated that Kepler telescope no longer, had enough fuel to maintain the precision required to continue searching for planets around other stars also known as exoplanets.
The Kepler telescope spends almost decade collecting information about the existence of thousands of planets. In facts, it helps to detect more than 2600 planets outside our solar system, included some in which there might be life.
“Kepler telescope far exceeded NASA’s expectations and paved the way for our exploration and search for life in the solar system and beyond.” agency associate administrator Thomas Zurbuchen.
Time has come, he wrote on Twitter. “Thank you for changing our view of the universe.”
The scientists explained that the “planet haunting telescope”, named after the German astronomer Johannes Kepler (1571-1630) and launched in March 2009, can no longer reorient or send information to earth.
Among his most recent discoveries is the theory that between 20 and 50 percent of the stars visible from our planet in the sky has planets around the size of the earth.
“When we started thinking about this mission 35 years ago, we did not know any planet outside the solar system,” said former NASA researcher and project initiator William Borucki. “Now we know there are planets everywhere, Kepler put us on a new course full of promises for a new generation to explore our galaxy.”
The time has come. As expected, @NASAKepler has run out of fuel. Throughout its lifetime, it has observed 500,000 stars & galaxies & has discovered 2,600+ planets beyond our solar system. Thank you for changing our view of the universe! https://t.co/tNnzdPlMkG

However, the mission faced many technical problems in fact since 2013 it operated in a limited way.
One of the successors of Kepler telescope has already started work in April. The “Transiting Exoplanet Survey Satellite (TESS).” The mission of 200 million dollars will last two years in principle. TESS is the size of the refrigerator and has four cameras.
Like the Kepler, TESS also observes the variations of the light of the stars that can be a sign of the passage of a planet. The TESS can detect both small rock bodies and huge celestial bodies and cover a much wider area than the Kepler telescope.
