Radio observatories around the world have reported capturing a unique event—a strong, millisecond-long burst of radio waves coming from a type of neutron star inside the Milky Way. Because of its strength, space scientists ...
Scientists have been able to observe the universe and determine that about 80% of the its mass appears to be "dark matter," which exerts a gravitational pull but does not interact with light, and thus can't be seen with telescopes. ...
