Solar ‘Pumpkin’: This photo was posted on NASA's Instagram site on Halloween and shows active regions on the sun combined to look something like a jack-o-lantern’s face. The image was captured by NASA’s Solar Dynamics Observatory in October 2014, which watches the sun at all times from its orbit in space.
The Keyhole Nebula (which is also known as the Carina Nebula or NGC 3372) is a glowing cloud of gas, dust, and stars some 8000 light years distant toward the constellation Carina. CN is a site of active star formation, and it contains stars that are ten times as hot and 100 times as massive as the Sun. The entire CN is some 200 lights years across.
