Planets can emit radio waves. For the first time, we’ve picked them up from outside the solar system.
The light we observe isn’t the same as the light that gets emitted. Here’s what causes it. The light you see, when you look out at the stars and galaxies that […]
The Red Planet, the God of War, and important life lessons for us all.
When we place the known objects in the Solar System in order, four inner, rocky worlds and four, outer, giant worlds stand out. Traditionally, these were defined as planets. Will […]
It took hundreds of years for Einstein to dethrone him, and even then, he was off by less than 1% of a spectacular prediction.
If spiral galaxies have a preferred direction, it just might be. “Since the beginning of physics, symmetry considerations have provided us with an extremely powerful and useful tool in our […]
