On the search for Earth like planets in other solar systems NASA wants to use the new, high-precision instrument called ENVY. The device can track the minimum tremor of a star, which is encircled by a planet.
Are there Earth-like planets in distant solar systems of the universe? This question is ancient and it is now traced with ever larger telescopes and space probes. To the 2000 exoplanets are now confirmed and to the thousands of candidates are constantly added.
The American space agency NASA and the National Science Foundation have put together now a team of scientists, which is to build a new, extremely precise instrument to detect other exoplanets. From 2019, envy will go in an Observatory in Arizona in operation.
Tremors of the star are caused by the gravity of the planet
The program is called NASA-NSF extrasolar planet observational research program, short NN-Explore. This program will focus on the instrument called ENVY is (pronounced “nee-id”), which is built under the guidance of Professor Suvrath Mahadevan from the Pennsylvania State University.
ENVY is an extremely precise Doppler Spectrometer, whose Konzept had previously been tested in a six-month study by NASA. The device measures the tiny periodic motions of a star orbiting a planet. The tremor due to the gravity of the planet in the orbit of the star and is also evidence on the size of the planet by its strength. It is one of the methods which can indirectly prove the extra-solar planets.
In PuTTY peak National Observatory in Arizona is envy as a new instrument on the 3.5 m large telescope WIYN added and there not the only device that is, on the search for extrasolar planets.
ENVY is closer to inspect the discoveries, which makes the space telescope Kepler, and help make possible observation targets for the planned James Webb Space Telescope – the successor of the Hubble telescope – and the space telescope mission planned in the 2020s WFIRST exploring.
ENVY is to help to search for new worlds
“The envy of high precision instrument is an integral part of the partnership between NASA and the National Science Foundation and will help us to search for new worlds”, said Paul Hertz, the NASA’s Director of Astrophysics. As engadget report tells that there are $10 million available for the construction of the spectroscope ready to be release in during three next years.
