Three types of rainforests: Boreal, Tropical and Temperate.
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 (:
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
Scientists just announced that our Sun is in a new cycle.
Solar activity has been relatively low over the past few years, and now that scientists have confirmed solar minimum was in December 2019, a new solar cycle is underway — meaning that we expect to see solar activity start to ramp up over the next several years.
The Sun goes through natural cycles, in which the star swings from relatively calm to stormy. At its most active — called solar maximum — the Sun is freckled with sunspots, and its magnetic poles reverse. At solar maximum, the Sun’s magnetic field, which drives solar activity, is taut and tangled. During solar minimum, sunspots are few and far between, and the Sun’s magnetic field is ordered and relaxed.
Understanding the Sun’s behavior is an important part of life in our solar system. The Sun’s violent outbursts can disturb the satellites and communications signals traveling around Earth, or one day, Artemis astronauts exploring distant worlds. Scientists study the solar cycle so we can better predict solar activity.
Surveying sunspots is the most basic of ways we study how solar activity rises and falls over time, and it’s the basis of many efforts to track the solar cycle. Around the world, observers conduct daily sunspot censuses. They draw the Sun at the same time each day, using the same tools for consistency. Together, their observations make up the international sunspot number, a complex task run by the World Data Center for the Sunspot Index and Long-term Solar Observations, at the Royal Observatory of Belgium in Brussels, which tracks sunspots and pinpoints the highs and lows of the solar cycle. Some 80 stations around the world contribute their data.

Other indicators besides sunspots can signal when the Sun is reaching its low. In previous cycles, scientists have noticed the strength of the Sun’s magnetic field near the poles at solar minimum hints at the intensity of the next maximum. When the poles are weak, the next peak is weak, and vice versa.
Another signal comes from outside the solar system. Cosmic rays are high-energy particle fragments, the rubble from exploded stars in distant galaxies that shoot into our solar system with astounding energy. During solar maximum, the Sun’s strong magnetic field envelops our solar system in a magnetic cocoon that is difficult for cosmic rays to infiltrate. In off-peak years, the number of cosmic rays in the solar system climbs as more and more make it past the quiet Sun. By tracking cosmic rays both in space and on the ground, scientists have yet another measure of the Sun’s cycle.
Since 1989, an international panel of experts—sponsored by NASA and NOAA—meets each decade to make their prediction for the next solar cycle. The prediction includes the sunspot number, a measure of how strong a cycle will be, and the cycle’s expected start and peak. This new solar cycle is forecast to be about the same strength as the solar cycle that just ended — both fairly weak. The new solar cycle is expected to peak in July 2025.

Some tips and tricks for getting glowy, beautiful, vibrant lighting effects…especially in traditional art, with no ctrl+z! The example piece is a watercolor work in progress of mine and, if you’re familiar with watercolor, you know it’s super unforgiving. What you put down stays!
Do a very loose, messy sketch of your illustration. This helps define the composition, but it can also help you pick where your light is coming from and what colors you’ll use for it. This way, you can reference the light source and colors while you’re painting!
Even if you’re working digitally, this creates a great color key you can turn back to. You can make a thumbnail digitally or traditionally.
This thumbnail only took about 20 minutes…and it’s saved so many headaches during the painting process.
When you have a thumbnail, the rest of your painting is just a translation of those colors with a better technique.
Tips:
Feel free to make many thumbnails! This is the easiest step to revise and repeat.
Use a photo for inspiration for your color scheme. I used clouds in the evening as color references.
Play around with layers and effects (like overlay, multiply). This can help you figure out new colors that you can then try to capture traditionally!
Line art is important for gradients! I did mine first, so I had to consider the glow effect too. It’s a bit blurry (as its a screenshot from a reel, lol), but you can see yellows to dark browns and blacks. This established the glow from the start!
Tips:
Consider using a media you can get gradients in. I used acryla gouache here, but ink, watercolor, and even markers can work well!
If it’s hard to visualize highlights in line art, do the lines after with pen or paint! Adding shadows and highlights that way can be easier.
Once you have your sketch on paper finished, start with large gradients! This helps define your light source and keep your whole composition making sense.
Here, I started with the background sky, then added in the shadow coming off the wing before doing anything else. Take note of how helpful the thumbnail was in helping me lay this all out, too!
See how both the hair and wings move from warm (yellow/browns) to cool colors (blues, payne’s grey)? This is a surefire way to keep the strong light source and make it look like the light is glowing!
Tips:
This is all about keeping the colors close to your light source, so if your light source is cool (like the moon), your highlights are cool and your shadows are warm tones. The key is just to keep it consistent!
Lighting isn’t just light to dark gradients. It’s also warm to cool/cool to warm!
Think about all the spots the light catches (like that one front feather on the left top). It takes a lot of thinking through, but it’ll make a huge impact! (Remember, you can always revisit your thumbnail or add more details in there)
Don’t forget about reflected light, bouncing off another surface. It’ll be more subtle than the main light source, but still there!
Final Tips:
Love those gradients! Watercolor is meant for beautiful gradients, so use multiple colors for a glow. The feathers in the light go from yellow ochre to prussian blue to payne’s grey.
Start with the highlights first, then work into the shadows! Above, the skin isn’t even painted with shadows yet, because I wanted to get the lighting first.
This is just a WIP right now, but I hope these tips help! If you want to follow, I’ll be posting more progress pics (and the finished illustration soon too). :D
I just reblog fun facts/tipsScience, nature, geology facts etc! + art & writing tips!
