Several other supernova progenitor candidates have been reported prior to the Hubble observation.

A tiny portion of this filament is revealed in detail by the Hubble observation.

However, the Hubble observations revealed it was "all or nothing," according to Grady.

In 2002, more than 3,500 published scientific papers grew out of Hubble observations.

The new Hubble observations continue the search for dark matter in individual galaxies.

The ring-like structure is evident in a composite image of the cluster made from Hubble observations.

The new Hubble observations reveal at least five inner shells and additional debris traveling away from the galaxy's center.

As a result, the number of scientific papers based on Hubble observations still grows every year.

In those views, the mirror images are blurry, with none of the sharp detail seen in the Hubble observations.

Saturn's south pole does not have a hexagon, according to Hubble observations.
