Description

NGC 2146 is a barred spiral galaxy of about 80,000 light-years across, located some 70 million light-years away in the northern constellation of Camelopardalis (The Giraffe). It is receding from us at roughly 893 kilometers per second.

NCG 2146 is undergoing intense bursts of star formation, to such an extent that it is referred to as a very active “starburst galaxy”. The gravitational disruption that NGC 2146 endures is compressing hydrogen-rich nebulae and triggering stellar birth. This is probably the reason that this galaxy is a strong source of radio emission.

NGC 2146 is classified as a barred spiral due to its shape, but the most distinctive feature is the dusty spiral arm that has looped in front of the galaxy's core as seen from our perspective. The forces required to pull this structure out of its natural shape and twist it up to 45 degrees are colossal. The most likely explanation is that a neighbouring galaxy is gravitationally perturbing it and distorting the orbits of many of NGC 2146’s stars. It is probable that we are currently witnessing the end stages of a process which has been occurring for tens of millions of years.--NASA
