Maunakea, Hawai’i – Astronomers have captured a bizarre image of a supernova, the powerful explosion of a star, whose light was so warped by the gravity of a galaxy that it appears as multiple images ...

Astronomers are living in a golden age of bigger and better telescopes. But even our most advanced technology pales in comparison to the power of nature’s own “cosmic magnifying glasses” – strong ...

A new image from the Hubble Space Telescope reveals the funny things that galaxies can achieve when they huddle together. When galaxies are far enough away, the 33-year old observatory gets a sort of ...

Jim Bickford is leading the Thin Film Isotope Nuclear Engine Rocket (TFINER) project to develop a system for propelling a craft through space faster and farther than ever before. This technology has ...
