(Phys.org) —It's been a busy week for space scientists—a team of astronomers discovered the first Thorne-Zytkow object—it's a weird type of hybrid between a red supergiant and a neutron star that looks like a regular ...
Billions of years ago, in the giant disk of dust, gas, and rocky material that orbited our young sun, larger and larger bodies coalesced to eventually give rise to the planets, moons, and asteroids we see today.
