haven't made new art lately so here's a really old doodle I reused for the postcard event

Edwin Hubble – Scientist of the Day

The 100" Hooker reflecting telescope on the top of Mount Wilson, near Pasadena, California, had opened for business in 1917, and it was the world’s largest telescope for the next 32 years.

finally got around to finishing the refs of the main five guys from cyberpunk m31!! they may change as the story goes on but this is what they look like rn :) also feel free to draw them and if you do i will love u 4ever and also show it to me and also ilu cyberpunk m31 by me & my boyfriend :)

Astronomy Photographers of the Year 2023

The photo above was shot by Marcel Drechsler, Xavier Strottner, and Yann Sainty, Capturing a moment of breathtaking beauty, earning them the title of Astronomy Photographers of the Year 2023 for their mesmerizing image, "Andromeda, Unexpected."

Andromeda, also known as Messier 31 or M31, is a spiral galaxy located approximately 2.537 million light-years away from Earth. It is the nearest spiral galaxy to our own Milky Way and is a prominent member of the Local Group, a collection of galaxies that includes our own and several dozen others. The history of Andromeda is as rich and complex as its luminous core, stretching back billions of years to the dawn of the universe itself.

The story of Andromeda begins with the birth of the cosmos in the Big Bang, a cataclysmic event that set in motion the expansion of space and time. Over billions of years, gravity drew together vast clouds of gas and dust, causing them to collapse and form stars. Among these stars were a family of galaxies.

Andromeda, like all galaxies, is a collection of billions of stars bound together by gravity. Its spiral arms, decorated with bright knots of star formation, wind around older, redder stars. At its core lies a supermassive black hole, a cosmic behemoth with a gravitational pull so strong that not even light can escape its grasp.

Andromeda's beauty is more than skin deep. It is a treasure trove of scientific knowledge, offering insights into the workings of the universe on scales both vast and small. Astronomers study its structure and dynamics to better understand how galaxies form and evolve over time. By measuring the motion of stars within Andromeda, they can infer the presence of dark matter, a mysterious substance that pervades the cosmos and binds galaxies together.

Astronomers believe that Andromeda is on a collision course with our own Milky Way, destined to merge in a cosmic tango that will reshape both galaxies in the distant future. This collision, which is expected to occur billions of years from now, will likely trigger a frenzy of star formation and reshape the landscape of both galaxies.

Drechsler, Strottner, and Sainty captured their award-winning image, "Andromeda, Unexpected." The photograph, taken with a combination of advanced telescopes and imaging techniques, reveals Andromeda in all its glory, its swirling arms and glowing core illuminated by the light of billions of stars. But what makes the image truly remarkable is the unexpected presence of a faint, wispy trail of gas extending from the galaxy's disk. A galaxy's disk refers to the flat, rotating component of a galaxy that typically contains most of its stars, gas, and dust.

This trail, known as a tidal stream, is remains of Andromeda's past. It is the result of gravitational interactions with smaller, satellite galaxies that have ventured too close to Andromeda and been torn apart by its immense gravity. These interactions have left their mark on Andromeda's structure, sculpting its shape and leaving behind a trail of stars and gas that serves as a silent testament to the galaxy's history.

Drechsler, Strottner, and Sainty's photograph captures not only the beauty of Andromeda but also the dynamic and ever-changing nature of the cosmos. It reminds us that galaxies are not static, unchanging objects but living entities that evolve and interact with their surroundings over billions of years.

Starless Andromeda. Part of my image processing workflow involves removing the stars on pictures I take so I can focus on bringing out the details on whatever object it is that I'm shooting. The stars are saved as a "star mask" that I can then reapply once I'm finished.

MAGIC—

M — "Messier 33," Warren muttered, turning to Thrive. "...That's Triangulum." (Meridian)

A — A long pause. Thrive lifted a hand to chest-level and out of his fingertips rose particles of light, the veins beneath his skin taking on the same glow as the obelisk. The light came together, swirled over his palm to form a star map of unidentified origins. (Aurora)

G — "Gladly." Warren leaned his hands onto the table. "Thrive's had virtually no issue being king until Delegate Sinkship took office, or, more accurately, all of the pushback he's received has been solved with a conversation or a compromise. Interestingly, that leads me to a pretty fun question…" He lifted his gaze to her. "Why does the human delegate have such sway over the others?" (Warpath)

I — "It is," Thrive said, unaffected on the surface. "It's who I, as an obhelian Protector, have been this whole time. I've done unforgivable things in my pursuit of justice, some of which have given me great satisfaction. I have moral ambiguity at times, mostly to do with my oath. I am not a saint. You and I have been together for several hundred years…I'm not sure how that slipped by you." (Asylum)

C — Controlling the essence w̷i̶t̷h̴i̸n̴ ̸y̸o̵u̵, the Emmuli growled. Disrupting the t̴r̴u̶t̸h̶, arresting your given capacity, reshaping your intelligence into the pattern t̴h̷e̸y̶ ̴f̷i̷t̷ ̸y̷o̷u̷ ̵t̷o̴ ̷d̷e̴s̵e̷r̶v̸e̷. (Eternal)
