#HubbleClassic This image shows the colorful "last hurrah" of a star like our Sun. The star is ending its life by casting off its outer layers of gas, which formed a cocoon around the star's remaining core. Ultraviolet light from the dying star makes the material glow. The burned-out star, called a white dwarf, is the white dot in the center. Our Sun will eventually burn out and shroud itself with stellar debris, but not for another 5 billion years.
Our Milky Way Galaxy is littered with these stellar relics, called planetary nebulae. The objects have nothing to do with planets. Eighteenth- and nineteenth-century astronomers named them planetary nebulae because through small telescopes they resembled the disks of the distant planets Uranus and Neptune.
The planetary nebula in this image is called NGC 2440. The white dwarf at the center of NGC 2440 has a surface temperature of nearly 400,000 degrees Fahrenheit. The nebula's chaotic structure suggests that the star shed its mass episodically. During each outburst, the star expelled material in a different direction. This can be seen in the two bow tie-shaped lobes. The nebula also is rich in clouds of dust, some of which form long, dark streaks pointing away from the star. NGC 2440 lies about 4,000 light-years from Earth in the direction of the constellation Puppis.
The image was taken February 6, 2007, with Hubble's Wide Field and Planetary Camera 2. The colors correspond to material expelled by the star. Blue corresponds to helium, blue-green to oxygen, and red to nitrogen and hydrogen.

Orion & Bioluminescence captured by @mohammadsadeghhayati ⠀
76 percent of ocean animals are bioluminescent, which means they produce their own light through a series of chemical reactions or host bacteria that do.
It’s a separate process from biofluorescence, in which blue light hits the surface of an animal and is reemitted as a different color, usually orange, red, or green.
Marine creatures rely on bioluminescence for communication, finding prey, camouflage, and more. It’s so important, in fact, that the trait has evolved 27 times among ray-finned fishes, a huge group that makes up half of all vertebrate species alive today.
