Builds Earth’s largest telescope on the other side of the moon

NASA engineers are investigating the possibility of building a massive, kilometer-wide radio telescope on the moon that would dwarf everything we could build on Earth. The telescope, which would be constructed by robots, would take the form of a huge wire mesh antenna in a bowl shape that would hang suspended in a three-kilometer-wide crater on the other side of …

Colliding white dwarfs produced bizarre slimy green zombie star

A white dwarf is not your typical star. While main sequence stars like our Sun melt nuclear material in their nuclei to prevent it from collapsing under their own weight, white dwarfs use an effect known as quantum generation. The quantum nature of the electrons means that no two electrons can have the same quantum state. When you try to …
