These planetary cores continue to interact with the white dwarf’s magnetic field, causing them to emit radiation detectable on earth. Read more on this on Universe Today.

Thirty-year-old computer science puzzle solved

The theory attempts to unify all the four fundamental forces of nature. The decision to award this theory came under fire on social media for multiple reasons. More about supergravity on Scientific American. Read a simply summed up criticism on the blog of physicist Sabine Hossenfelder.

Earth’s last magnetic field switch took longer than previously thought
