Glowing Clouds in Space
In 2012, NASA's Swift space telescope captured an image of a glowing cloud of gas in the constellation of Centaurus, 15,000 light-years from Earth. This phenomenon is known as a "supernova remnant" and is the result of a star explosion that occurred around 1,000 years ago. The cloud is still glowing with the energy released during the explosion, making it visible from space. This fascinating sight is a rare opportunity to observe the aftermath of a massive stellar event.
