This picture taken with ESO’s Very Large Telescope shows the galaxy NGC 1187. This impressive spiral lies about 60 million light-years away in the constellation of Eridanus. NGC 1187 has hosted two supernova explosions during the last thirty years, the latest one in 2007.

NGC 1187 looks tranquil and unchanging, but it has hosted two supernovae explosions since 1982. A supernova is a violent stellar explosion, resulting from the death of either a massive star or a white dwarf in a binary system. Supernovae are amongst the most energetic events in the Universe and are so bright that they often briefly outshine an entire galaxy before fading from view over several weeks or months. During this short period a supernova can radiate as much energy as the Sun is expected to emit over its entire life span.

In October 1982, the first supernova seen in NGC 1187 — SN 1982R was discovered at ESO’s La Silla Observatory and more recently, in 2007, the amateur astronomer Berto Monard in South Africa spotted another supernova in this galaxy — SN 2007Y. A team of astronomers subsequently performed a detailed study and monitored SN 2007Y for about a year using many different telescopes. This new image of NGC 1187 was created from observations taken as part of this study and the supernova can be seen, long after the time of maximum brightness, near the bottom of the image.

This chart shows the location of NGC 1187 in the constellation of Eridanus. This map shows most of the stars visible to the unaided eye under good conditions, and NGC 1187 itself is highlighted with a red circle on the image. This galaxy appears as a faint smudge through medium-sized amateur telescopes under good conditions.

This wide-field view is centred on the spiral galaxy NGC 1187 in the constellation of Eridanus. It is a colour composite made from exposures from the Digitized Sky Survey 2 (DSS2). The distorted companion galaxy ESO 480-G020 can be seen to the upper-right of NGC 1187, close to a star. The bright star at the bottom of the picture is Tau3 Eridani.

NGC 1187 (Spiral Galaxy) : Movie

Zooming in on the spiral galaxy NGC 1187
This zoom video sequence starts with a wide view of the large but faint constellation of Eridanus, not far from the more familiar form of Orion. As we zoom in we see a small patch of light that proves to be an attractive spiral galaxy named NGC 1187. The detailed final view shows a new VLT image of this object.
