The telescope's exquisite images of dying stars help scientists understand the death process and how it is influenced by each star's specific circumstances. Only Hubble can chronicle the spectacular changes as the blast debris expands over time.
Hubble was the first optical telescope to provide convincing proof of a black hole several billion times the mass of the Sun. Now it is demonstrating that supermassive black holes are at the core of most, if not all, galaxies.
Hubble captured the best view of Mars ever obtained from Earth. Frosty white water ice clouds and swirling orange dust storms above a vivid rusty landscape reveal Mars as a dynamic planet in this sharpest view ever obtained by an Earth based telescope. The Earth-orbiting Hubble telescope snapped this picture on June 26, when Mars was approximately 43 million miles (68 million km) from Earth -- its closest approach to our planet since 1988. Hubble can see details as small as 10 miles (16 km) across.
