NGC 6992 is a supernova remnant located in the constellation Cygnus(2). It is also known as the Eastern Veil Nebula, and it is part of a larger structure of dark molecular clouds that harbors many regions of nebulosity with active star formation(5). The supernova that created NGC 6992 is estimated to have occurred around 8,000 years ago(3).
NGC 6992 is a complex structure with intricate filaments and knots of gas and dust. It is composed of ionized gas, which emits light at specific wavelengths, and dust, which absorbs light and causes the structure to appear dark in some areas(2). The structure is approximately 110 light-years across and is expanding at a rate of about 600 km/s(3). The supernova explosion that created NGC 6992 is thought to have been a Type II supernova, which occurs when a massive star runs out of fuel and collapses under its own gravity(6). The resulting explosion sends shock waves through the surrounding gas and dust, which can trigger the formation of new stars(5).
