NGC 3370 (also Silverado Galaxy, IRAS 10444+1732, MCG 3-28-8, UGC 5887 and PGC 32207) is a magnitude +12.3 spiral galaxy located 98 million light-years away in the constellation Leo.

The galaxy was discovered by German-British astronomer William Herschel using a 47.5 cm (18.7 inch) f/13 speculum reflector at Datchet, Berkshire, on the 21st March 1784.

The image is roughly 3.4 arcminutes (95,000 light-years or 29,000 parsecs) wide.

The `red dots` in the image are background galaxies.

Similar in size and grand design to our own Milky Way, spiral galaxy NGC 3370 lies about 98 million light-years away toward the constellation Leo. Recorded here in exquisite detail by the Hubble Space Telescope's Advanced Camera for Surveys, the big, beautiful face-on spiral, about 95,000 light-years wide, does steal the show, but the sharp image also reveals an impressive array of background galaxies in the field, strewn across the more distant Universe.

Looking within NGC 3370, the image data has proved sharp enough to study individual pulsating stars known as Cepheids which can be used to accurately determine this galaxy's distance.
NGC 3370 was chosen for this study because in 1994 the spiral galaxy was also home to a well studied stellar explosion -- a type Ia supernova. Combining the known distance to this standard candle supernova, based on the Cepheid measurements, with observations of supernovae at even greater distances, can reveal the size and expansion rate of the Universe.
