By using Gaia satellite, a team of scientists, with a little help from amateur astronomers, have found an extremely rare star system: a binary system where one star completely eclipses the other, the first of its kind ever discovered.
Supernovae are rare in occurrence, but at the center of an enigmatic nebula lie two stars that astronomers say will eventually end in a fiery, violent supernova. Astronomers believe that the two stars are set in such a tight orbit that they will merge and cause each other’s explosion and death.
Children and adults alike marvel at the rings around Saturn. In a model of our solar system, Saturn — and its rings —is typically the one that gets the most attention. But while it is easy to be fascinated by Saturn, astronomers have recently found an exoplanet with an even grander expanse of wings that is sure to wow a new generation of stargazers.
Far beyond the orbit of Neptune, trillions of comets left over from the formation of the solar system lie in wait in a region known as the Oort cloud. Here they are kept in relatively stable orbits around the sun, posing little threat to Earth save for the occasional icy rock that ventures inwards. But in the blink of a cosmic eye that could all change.
