From Earth to the Universe: Picture of the day


FORNAX A

Two vast 'Dumbo' ears of radio emissions surround the galaxy NGC 1316, forming an object that radio astronomers call Fornax A. The emission, picked up by the Very Large Array radio telescope and shown in orange, is generated as charged particles are blasted from the core of the galaxy and crash into the intergalactic gas. The particles come from near the black hole at the core of NGC 1316, and result from it devouring material from its smaller neighbour.

In 2009, the "From Earth to the Universe" project brought astronomy to millions of people around the world. Take a tour of just some of the locations in a short video on the FETTU Highlights page.
