Quick fact: in 2007, ESA's FOTON-M3 mission exposed tardigrades to the vacuum, cold, and radiation of open space for 10 days. Some of them survived and even reproduced afterward, making them the only animal known to survive direct exposure to space.
Quick fact: a teaspoon of neutron star material would weigh about a billion tonnes on Earth. Neutron stars pack more mass than the Sun into a sphere about the size of a city, held together by gravity extreme enough to bend the light around it.
Quick fact: the Wow! Signal was a 72 second radio burst picked up in 1977, so strong the astronomer who found it circled it on the printout and wrote "Wow!" next to it. It has never repeated since, and nearly 50 years later, nobody has fully explained it.
