(−1.46 apparent magnitude), Canopus (−0.86) and Alpha Centauri (−0.27). However, Alpha Centauri is a binary star, whose unresolved components to the naked eye are both fainter than Arcturus. This makes Arcturus the third-brightest individual star, just ahead of Alpha Centauri A, whose...
Proxima Centauri (Alpha Centauri C) is a red main sequence star in the constellation of Centaurus. It is too faint to be seen in the southern hemisphere night sky without a telescope. Proxima Centauri distance from Earth is 4.23 light years away.
One of my favorite daydreams is also one of my scariest. When I am outside on a clear, cloudless night, I like to imagine that I am on a spaceship in the deep between the stars, looking out at the vastness of the universe. During this daydream, I often fondly recall my favorite sc...

intriguing type of quantum system known as a discrete time crystal (DTC). Whereas normal, material crystals display a fixed-dimensional periodicity in their structure, DTCs repeat their properties in time, with cycles that have an integer multiple of the period of the force that causes the ...
