NASA began the search for “Earth’s twins”

В NASA начали поиски «двойников Земли»

The TESS telescope was launched in April of this year.

Orbital Observatory TESS successfully passed all checks of tools and began observations of the brightest stars of the Galaxy, next to which can hide a full-fledged counterpart of the Earth.

“I am incredibly pleased that our new “hunter planet” began to “sweep” the Galaxy in search of still unknown worlds. Now we are well aware that the planets in the Universe is more than stars, and I look forward to the opening of the extremely bizarre and just plain weird worlds,” said Paul Hertz (Paul Hertz), the head of the Astrophysics division of NASA.

The TESS telescope was launched in April this year as a replacement for its illustrious predecessor, of the space Observatory “Kepler” discovered thousands of exoplanets in eight years. The fuel reserves on Board now coming to an end, and scientists expect that it will finally cease observations in the near future.

In contrast, TESS will monitor the area on the sky, as did Kepler in the first four years of operation in orbit, and for different parts of the cosmos, which are interesting to scientists, stars and planets.

Another innovation will be that TESS will not watch for the sun and bright stars, about the planets that astronomers today know almost nothing. Their “census” as scientists hope, will show how often unable to form analogs of the Land from the larger, brighter stars, and how likely the origin of life on the surface.

Like Kepler, TESS will discover new planets, looking for periodic fluctuations in the brightness of stars, indicating that their light is temporarily blocked by one or more planets.

This technique allows you to quickly and accurately open planets close to stars, but it has several disadvantages. For example, it is not adapted to search for very small and distant planet makes one revolution around the sun for a few hundred years, and it is not possible to accurately determine the mass of open akterov.

For this reason, all of the most interesting discoveries will be explored further TESS of the largest ground-based telescopes that can open the planet for the shifts in the spectrum of their star, and built orbital Observatory “James Webb”, which will replace the Hubble in the early 2020s.

Last week, as noted by Hertz, all checks TESS was successfully completed, and the telescope started scientific observations. First images and data will be transferred to the ground in early August, scientists will immediately begin to search for traces of exoplanets within them.
