Young Star HR 4796A (IMAGE) NASA/Goddard Space Flight Center Caption Hubble uncovers a vast, complex dust structure, about 150 billion miles across, enveloping the young star HR 4796A. A bright, narrow inner ring of dust is already known to encircle the star, based on much earlier Hubble images. This newly discovered huge dust structure around the system may have implications for what a yet-unseen planetary system looks like around the 8-million-year-old star. Credit NASA/ESA/G.
