7 Beautiful cosmology photos captured by NASA space telescope

Star Factory W51: The star-forming nebula W51 is one of the largest "star factories" in the Milky Way galaxy. NASA's Spitzer Space Telescope captures the infrared light that can penetrate dust clouds.

Swift’s UV Portrait of the Andromeda Galaxy: NASA's Neil Gehrels Swift Observatory viewed our neighboring spiral galaxy Andromeda, also called M31, in ultraviolet light.

Swan Nebula: NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) detected the blue areas near the center of this composite image of the Swan Nebula, revealing gas as it’s heated by massive stars located at the center.

RCW 120: The ring-shaped clouds around the nebula RCW 120 were detected by NASA's Spitzer Space Telescope in this composite image.

Hubble Spots Fireworks in Westerlund 2: A brilliant tapestry of young stars flaring to life resembles a glittering fireworks display in this Hubble Space Telescope image. Located 20,000 light-years away from Earth.

Star jets: This image features a rare celestial phenomenon known as a Herbig-Haro object or a star jet. It is named HH111, imaged by the NASA Hubble Space Telescope’s Wide Field Camera 3 (WFC3).

Einstein Ring: GAL-CLUS-022058s is the largest and one of the most complete Einstein rings ever discovered in our Universe. The narrow galaxy elegantly curving around its spherical companion in this image is a very rare phenomenon.
