Spiral Galaxy NGC 1559

Spiral Galaxy NGC 1559

Roughly 50 million light-years away lies a considerably neglected little galaxy named NGC 1559. Pictured right here by Hubble’s Vast Subject Digicam 3, this barred spiral lies within the little-observed southern constellation of Reticulum (The Reticule).

NGC 1559 has huge spiral arms chock-full of star formation, and is receding from us at a velocity of about 1300 km/s. The galaxy incorporates the mass of round ten billion Suns — whereas this may occasionally sound like quite a bit, that’s nearly 100 instances much less huge than the Milky Means. Though NGC 1559 seems to sit down close to certainly one of our nearest neighbours within the sky — the Giant Magellanic Cloud (LMC), that is only a trick of perspective. In actuality, NGC 1559 is bodily nowhere close to the LMC in area — in truth, it really is a loner, missing the corporate of any close by galaxies or membership of any galaxy cluster.

Regardless of its lack of cosmic companions, when this lonely galaxy has a telescope pointed in its route, it places on fairly a present! NGC 1559 has hosted quite a lot of spectacular exploding stars referred to as supernovae, 4 of which we now have noticed — in 1984, 1986, 2005, and 2009 (SN 1984J, 1986L, 2005df [a Type Ia], and 2009ib [a Type II-P, with an unusually long plateau]).

NGC 1559 could also be alone in area, however we’re watching and admiring from distant.
