A composite image of M51 with X-rays from Chandra and optical light from NASA''s Hubble Space Telescope contains a box that marks the location of the possible planet candidate.

Where is Earth in the Milky Way Galaxy?

We''ll look at the basics of the Milky Way galaxy, its structure, and the specific location of Earth within this galaxy. Then, we''ll discuss the methods scientists use to determine Earth''s position, the movement of our planet within the Milky Way, and some interesting facts about our perspective from Earth.

Are We Alone?

We''ve found thousands of planets in our Milky Way galaxy, a large fraction of them in Earth''s size range and orbiting in their stars'' "habitable zones" – the distance from the star at which liquid water could exist on the surface. We know the galaxy likely holds trillions of planets. Our telescopes in space and on the ground, and our remote

How many planets are in the Milky Way?
