IC 1295 is a planetary nebula in the constellation Shield . It is about 3,600 light years away.
The VLT image shows that the star remnant is surrounded by multiple envelopes. These bubbles consist of gas that originally formed the star's atmosphere and is blown into the surrounding space by irregular stellar winds . The gas bubbles are stimulated by the strong ultraviolet radiation of the central star (you can recognize it as a bright blue-white point in the middle of the nebula) and thereby make them glow. Different chemical elements emit different colors; the green shade in IC 1295 comes from ionized oxygen.
The planetary nebula IC 1295 was discovered on August 28, 1867 by the American astronomer Truman Henry Safford .
