These 'clouds' are actually galaxies close to our own Milky Way.

In one of the binary stars in our galaxy called FH Leo, we discovered the super flare.

Evolution Interstellar clouds like the Orion Nebula are found throughout galaxies such as the Milky Way.

So, we can even put a number to how many of those planets now do we expect our own Milky Way Galaxy harbors.

These stars are rare it is estimated that there are no more than 20,000 in the entire Milky Way.

Today, we don t need to rely on such verbal descriptions of our planet s insignificance against the background of our galaxy.

I'm interested in finding whether or not there is a really massive, what we like to call supermassive black hole at the center of our galaxy.

Now, the advantage of studying our own galaxy is it's simply the closest example of the center of a galaxy that we're ever going to have, because the next closest galaxy is 100 times further away.

And by everything I mean, of course, me and you, the Earth, the Sun, the 100 billion suns in our galaxy and the 100 billion galaxies in the observable universe.

If dark matter exists in our universe, in our galaxy, then these particles should be smashing together and producing other particles that we know about one of them being neutrinos.

And, if even all of the planetary systems in our galaxy were devoid of life, there are still 100 billion other galaxies out there, Now, I'm going to try a trick, and recreate an experiment from this morning.

With the exception of supernovae, individual stars have primarily been observed in our Local Group of galaxies, and especially in the visible part of the Milky Way (as demonstrated by the detailed star catalogues available for ourgalaxy).

And the fun phase of this experiment is, while we've tested some of our ideas about the consequences of a supermassive black hole being at the center of our galaxy, almost every single one has been inconsistent with what we actually see.

The galactic coordinate system is a celestial coordinate system in spherical coordinates, with the Sun as its center, the primary direction aligned with the approximate center of the Milky Way galaxy, and the fundamental plane approximately in the galactic plane.

Our team, befittingly I think, named it after one of those dreamers of the Copernican time, and that telescope's sole purpose is to go out, find the planets that orbit other stars in our galaxy, and tell us how often do planets like our own Earth happen to be out there.
