We know that all the 8 planets are moving around Sun. Will there ever be a moment when all eight major planets are in a straight line on the same side of the Sun?
If I lived on Saturn, would its rings be visible from the equator or the poles?
Astrophysicists are using new methods to simulate the common-envelope phase of binary stars, discovering dynamic irregularities that may help to explain how supernovae evolve.
Mars may well have had plentiful water billions of years ago—but it was mostly ice, not liquid, a study claims. Researchers say a cold and icy planet billions of years ago better explains water drainage and erosion features seen on the Red Planet today.
Scientists have used computer simulations to work out how a strange 555-million-year-old creature, with no known modern relatives, ate. The result, surprising for that time period, reveals that some of the first large organisms formed ecosystems that were much more complex than previously thought, researchers claim.
