Fashions fade, style is eternal.
Forty million light-years from Earth, a galaxy starts to lose its shine as its gas and dust recede – without the star-making material, the galaxy will eventually fade.
Stars are formed when immense clouds of gas and dust collapse under their gravitational attraction; as the cloud collapses, a dense hot core forms and begins to gather more material, which can become planets, asteroids, comets, or remain dust.
The remnants of this spiral galaxy’s massive arms can be seen in this image taken by @NASAHubble. The galaxy lies in the constellation Dorado (the Dolphinfish) and can only be seen in the southern hemisphere.
Image description: Thousands of stars surround this image of a galaxy that has a bright core and concentric circles of brown dust emanating from its center.
