"We finally have the first look at our Milky Way black hole, Sagittarius A*," an international team of astrophysicists and researchers from the Event Horizon Telescope team said.

While researchers have found more than 4,000 planets in our own galaxy, this is the first time anyone has found what could be a planet that exists outside the Milky Way.

Scientists have used a NASA probe way out in space, beyond Pluto, to measure visible light that's not connected to any known source such as stars or galaxies.
