NASA shows first star photo from space telescope TESS – IT Pro – News

 

TESS is not really a telescope with a real zoom lens so what you see there you can see in a remote location with binoculars, you will also see infinite stars.What TES does hundreds of suns in the sky at the same time and long-term (month) in the search, but a small dip in the light of that star / sun. One speaks of a transit and that transit are planets that revolve around their sun. They can fairly accurately calculate the mass, temperature, distance to its sun and circumference of that planet in order to determine how readable that planet is.
James webb telescope kicks in by zooming in extremely on stars with planets that have the greatest chance to have life. Because the star shines through the atmosphere of its planet, you can measure that atmosphere. How much co2 there is, oxygen etc. One could even see if there is or is not vegitation on that planet.
So there is a real chance that we will come to the realization in the next 10 years that our planet is not the only planet with life (vegitation, organisms to intelligent life). But only with the James Webb space telescope (JWST), but in the up to 2021 (first) waiting for the launches.
Meanwhile, TES can eagerly discover new planets. That is going fast. Kepler looked only in a small part of the helal. TES will scan 400x more space.
The sad news is even if we already find an earth2, or signs of intelligent life … it is and remains a kind of dream image because the distances are astronomically large that even at light speed you are traveling for thousands or even millions of years for a visit.
In the bargain, you watch millions of years in the past so everything we observe is often a schism of days gone by, although there are also (minority) solar systems such as alpha centauri with 3 stars at just over 4 light years away. Hope makes life.
