There is an official date for the opposition of Mars, but that's not the only night to observe it. The Red Planet will actually be brighter three days earlier, when it's closer to Earth (a consequence ...

That's because 2025 is not what astronomers call a "perihelic opposition," which is when Mars gets closest to Earth while near its closest point to the sun on its slightly elliptical orbit.

Our galaxy, while not small, isn't nearly as big as Andromeda. We harbor some 100 to 400 billion stars. One day, however, the two galaxies may collide, forming a giant, egg-shaped elliptical galaxy.

"Because it's such a large supermassive black hole at the center, we'd predicted we'd see an elliptical galaxy." The spiral host galaxy, a quasar named J0742+2704, was discovered emanating a ...

While the general interval is around 26 months, some oppositions can be more closely spaced due to the elliptical nature of Mars's orbit. For instance, "perihelic oppositions," which occur when ...

Andromeda is the closest large galaxy to the Milky Way. And it is getting closer, as the two will merge in several billion years. It has been an object of study for centuries, but we have never ...
