Takeways in the middle of the Milky Way The black hole supermajero called Sagittarius A* is located in the middle of the Milky Way. The observations of S2 and other stars also helped astronomers calculate the extraordinary size and mass of Sagittarius A* and weighs approximately 4.3 million solar masses. Although the entire Milky Way,…
Astronomers may be beginning to obtain products on the lava planets. These burning worlds share a density similar to Earth, but an orbit so close to their host stars that their diurnal abrasing temperatures melt the same rocks from which they are made, creating possible magma oceans that cover their surface. While Lava Mundos represent…
