Pan of NGC 1559

This video features a new image of the barred spiral galaxy galaxy NGC 1559 as seen by the NASA/ESA/CSA James Webb Space Telescope. The galaxy hosts a visible central region with a distinct open pattern in the loosely-wound spiral arms. NGC 1559 resides approximately 35 million light-years away in the little-observed southern constellation Reticulum (The Reticule).

The data featured in this portrait make use of two of Webb’s instruments: the Mid-InfraRed Instrument (MIRI) and Near-InfraRed Camera (NIRCam). Here MIRI captures the glow of interstellar dust grains, which trace out the interstellar medium, the fuel for future star formation. NIRCam shows the light from stars, even young stars hidden behind prodigious amounts of dust. NIRCam also captures emission from ionised nebulae around young stars.

NGC 1559 has massive spiral arms that abound with star formation, and it is receding from us at a speed of about 1300 kilometres per second. Although NGC 1559 appears to sit near one of our nearest neighbours in the sky — the Large Magellanic Cloud (LMC) - this is just a trick of perspective. In reality, NGC 1559 is physically nowhere near the LMC in space; in fact it truly is a loner, lacking the company of any nearby galaxies or membership of any galaxy cluster.
