A Supernova in the Whirlpool - April 21st, 1996.
"In 1994, a new star in a distant galaxy was seen by amateur astronomers, who alerted the world to their discovery of a supernova. Near the nucleus of spiral galaxy M51, popularly known as the Whirlpool, this supernova (1994I) is identified as the bright spot indicated by the arrow in the lower left of this Hubble Space Telescope image. Supernovae are violent death explosions of stars that eject radioactive debri clouds. They are often discovered by amateur observers dedicated to systematic searches of the sky, and are of intense interest to astronomers who hope to learn what kind of stars generate these explosions, and what chemical elements are produced and mixed into space. Distances to these intrinsically bright events can also be determined, providing crucial yardsticks for measuring the scale of the Universe."

It’s oh-so-easy to be mesmerized by this spiral galaxy known as NGC 4254. Follow its clearly defined arms, which are brimming with stars, to its center, where there may be old star clusters and, sometimes, active supermassive black holes. NASA’s James Webb Space Telescope delivered highly detailed scenes of this spiral galaxy in a combination of near- and mid-infrared light.

A Spiral Galaxy Gallery - April 9th, 1996.
"A progression of beautiful spiral galaxies is illustrated above with three photographs from NASA's Ultraviolet Imaging Telescope (UIT). Flying above the Earth's obscuring layer of atmosphere on the Space Shuttle Columbia during the Astro-1 mission in 1990, UIT's cameras were able to image these distant spirals in the ultraviolet light produced by hot, young stars. These bright stars, newly condensed from gas and dust clouds, give away the location of the spiral arms they are born in. Because they are massive (many times the mass of the Sun), they are shortlived. Dying and fading before they move too far from their birth place, they make excellent tracers of spiral structure. From left to right the galaxies are known as M33, M74, and M81, and have progressively more tightly wound spiral arms. Astronomers would classify these as Scd, Sc, and Sb type spirals using a galaxy classification scheme first worked out by Edwin Hubble."

Sun Mickey
67/365 #hunt the mouse
Tumblr media
This one was pretty quick. I love orange and I love cosmic stuff, so this came together just under half a hour. I imagine him sort of feeling like he can play god.
I am making 365 new versions of Mickey Mouse for the public domain and releasing them under public domain all year long.
You can join the initiative to #hunt the mouse or suggest a theme yourself via my ask box.
