NGC 3370: Celestial Composition

Spiral Galaxy NGC 3370, Home to Supernova Seen in 1994

Amid a backdrop of far-off galaxies, the majestic dusty spiral, NGC 3370, looms in the foreground in this NASA Hubble Space Telescope image. Recent observations taken with the Advanced Camera for Surveys show intricate spiral arm structure spotted with hot areas of new star...

Galaxy NGC 3370 Comparison of Ground and ACS Images

SN 1994ae was discovered by S. Van Dyk and the Leuschner Observatory Supernova Search (IAU Circular 6105) using an automated 0.76-meter telescope. The discovery image was taken on Nov. 14, 1994. The supernova was located about 30".3 west and 6".1 north of the galaxy's nucleus....

Cepheid Variable in NGC 3370

Here we see a "movie" of 12 consecutive epochs of a long period (~50 days) Cepheid variable. The Cepheid is in the center of a crowded region of stars. The resolution of HST is required to pick out the variable star from its neighbors. The star was caught initially fading before...
