i learned about Tim Wong who successfully and singlehandedly repopulated the rare California Pipevine Swallowtail butterfly in San Francisco. In the past few years, he’s cultivated more than 200 pipevine plants (their only food source) and gives thousands of caterpillars to his local Botanical Garden (x)
The Cats Eye Nebula in Optical and X-ray : To some it looks like a cat’s eye. To others, perhaps like a giant cosmic conch shell. It is actually one of brightest and most highly detailed planetary nebula known, composed of gas expelled in the brief yet glorious phase near the end of life of a Sun-like star. This nebula’s dying central star may have produced the outer circular concentric shells by shrugging off outer layers in a series of regular convulsions. The formation of the beautiful, complex-yet-symmetric inner structures, however, is not well understood. The featured image is a composite of a digitally sharpened Hubble Space Telescope image with X-ray light captured by the orbiting Chandra Observatory. The exquisite floating space statue spans over half a light-year across. Of course, gazing into this Cat’s Eye, humanity may well be seeing the fate of our sun, destined to enter its own planetary nebula phase of evolution … in about 5 billion years. via NASA
a friend of mine was having trouble with a character of hers, he was middle-aged but looked too young, so she came to me for help. i'm something of a middle-aged-man-fan so i whipped up this quick thing to help her out. it might be useful to somebody out there so i'll share it here too!
i learned that the north star is 4000 times brighter than our sun. The light we see when we look at the north star was generated in the year 1587, and it has been traveling through space for 434 years to reach us (x)
Astronomers think they have found a galaxy that existed just 300 million years after the big bang. The galaxy named HD1 is so old, it likely only exists of what are known as population iii stars, the very first stars that ever came into existence, made of mostly hydrogen, helium and a small amount of beryllium and lithium.
We have never seen any population iii stars, and according to the theories of the early universe, most of these stars would have been colossal blue giant stars that wouldn't have lived very long at all, a few million years at most before going supernova and collapsing into black holes.
One thing that really stands out about this galaxy is it's unusually powerful in ultra violet light, a common feature of massive blue giant stars, but the amount seen in this galaxy may indicate the presence of a supermassive black hole behaving as a quasar, if this is correct, it will be the earliest example of a blackhole too.
If supermassive black holes were present just 300 million years after the big bang, it may be evidence that black holes were being created much earlier than previously thought.
The next step is to turn the James Webb Telescope towards it, and while it is more focused on the Infra Red, it will be able to resolve much more detail than Hubble, and maybe begin to see if indeed, this was a Qasar just 300 million years into the Universe's existence, or if the galaxy was producing far more stars than even the most prolific starburst galaxy would do today.

I'm currently working on an animatic, could you give me any advice?

I still haven’t taken any animation or storyboarding classes, but these are general TECHNICAL tips I’ve learned online and through trying to fix my own boards. Definitely practice with things your passionate about/interested as it’ll make the process so much more fun (: for me the technical parts aren't the hardest, moreso actually visualizing and deciding the scenes mentally, which takes practice.
Also 6 cuz yeee:
I had a classmate laugh cuz I said I used wmm for my boards and he thought he needed a fancy $7 blue pencil LIKE NO BRO JUST USE WHAT YOU HAVE IF YOU CAN’T AFFORD THINGS LOLLLL. I have a small huion screen now, but it’s down to preference cuz honestly I prefer paper over digital 0′;
Good luck though! Once I take classes or if I have more tips id gladly share them with yall (:
also known as RAFGL 2688 and CRL 2688, the Egg Nebula is located 3000 light years from Earth in the constellation of Cygnus.
The nebula is a bi-polar proto-planetary nebula, or essentially a star in the dying days of it's existence starting to throw out shells of atmosphere as it moves towards being a white dwarf.
The central star is concealed by an area of dust with the light poking out in areas where the dust is lightest, this is thought to be an accretion disk around the star.
