We live on a planet that seems motionless, yet Earth orbits the Sun at a dizzying speed, and our entire Solar System moves through the galaxy. But how fast exactly are we traveling through

A large radio galaxy study finds our solar system moves faster than theory predicts, raising new questions about how matter spreads.

How fast and in which direction is our solar system moving through the universe? This seemingly simple question is one of the key tests of our cosmological understanding. A research team led by astrophysicist Lukas Böhme at Bielefeld University has now found new answers,

The object, estimated to be the size of a city block, is only the third known interstellar visitor to our solar system since scientists began

The study showed that Enceldus’ conditions hold the most promise for sustaining life. The research team predicts that the moon is capable of supporting as many as 42,900 cells per cubic centimeter at a depth of two feet, Mars can support 11,600 cells at just over half a meter below the surface, and Europa can support 4,200 cells at one meter deep.

Collisions with the solar wind would ensure we were well aware of an antimatter comet entering our solar system, explains one reader

Study from Bielefeld finds major departure from the standard model. How fast and in what direction is our solar system moving through space? This question, though simple in appearance, plays a central role in testing modern cosmological theories.
