Stars And Dust Across Corona Australis : Cosmic Dust Clouds Cross A Rich Field Of Stars In This Telescopic

Stars And Dust Across Corona Australis : Cosmic Dust Clouds Cross A Rich Field Of Stars In This Telescopic

Stars and Dust Across Corona Australis : Cosmic dust clouds cross a rich field of stars in this telescopic vista near the northern boundary of Corona Australis, the Southern Crown. Less than 500 light-years away the dust clouds effectively block light from more distant background stars in the Milky Way. Top to bottom the frame spans about 2 degrees or over 15 light-years at the clouds’ estimated distance. At top right is a group of lovely reflection nebulae cataloged as NGC 6726, 6727, 6729, and IC 4812. A characteristic blue color is produced as light from hot stars is reflected by the cosmic dust. The dust also obscures from view stars in the region still in the process of formation. Just above the bluish reflection nebulae a smaller NGC 6729 surrounds young variable star R Coronae Australis. To its right are telltale reddish arcs and loops identified as Herbig Haro objects associated with energetic newborn stars. Magnificent globular star cluster NGC 6723 is at bottom left in the frame. Though NGC 6723 appears to be part of the group, its ancient stars actually lie nearly 30,000 light-years away, far beyond the young stars of the Corona Australis dust clouds. via NASA

a digital artist’s guide to digital art guides

hi my qualification for writing this guide to youtube art tutorials (though it may be applicable to other forms of media as well) is that i have watched over (roughly) 200 art tutorials of various length, artistry, content, style, and more

when we’re told “look up guides online” there’s not really much more to say on how to approach our research and taking them in, so if you’re a little lost in the vast sea of art help like i was as a wee bab, then this may help!

General Use:

don’t feel bad for skipping - if something isn’t striking you as informative or helpful, don’t feel bad for moving right along and treating it like a sponsor

^ also applies for lengthy talking or deriving from the point, if you’re not up for it. you don’t need to sit through the artists’ whole spiel to learn how to draw hands.

if something isn’t making sense, reach out to communities for help, and go beyond youtube/tumblr. reddit and discord servers are also full of places to go to talk to more ppl

trust your gut! if someone’s style makes you go “hmm this feels wrong and objectifying”, it’s because it is - feel free to move right along

^ also applies for if it feels like the artist is just showing off and not explaining enough, or just posting for ego boost or to get coin.

… related tip but if an artist likes to rant about discourse as the primary thing on their channel, i know drama can be fun and juicy but please just avoid these people, because generally they’re either nasty and toxic-minded, or they seem to have some bs going on for them in the background

check out comments and online discussion to see how well received a popular artist is, and pay attention to their discourse to avoid any mistakes they unintentionally or even proudly display

the art program is not important!!! every art program has some level of similar functionality, some with more bells and whistles than others, and very rarely does one program lack a key tool the others don’t have. the hardest part is translating what your artist means when they say one thing but your program has another - but more often than not, some similar wording or like words are used for the same tool or setting.

^ this means you can watch that tutorial on how to draw legs for clip studio if all you have is firealpaca

Information over Entertainment! the best artists to find help in are ones who focus primarily on relaying information and less on colorful quirky editing - those kinds CAN be helpful, but in general i tend to find more useful tips in videos that feel more academic as opposed to more entertaining.

don’t feel bad for flatout ignoring advice. if you found something that works better for you, please use it. feel free to try new techniques as well if you’re feeling stuck or want a change of pace!

Terms and Conditions:

What words should you use when finding the right video? Think like a content creator, here. General words are best when searching for the right video, and in order to think of those words, you need to know the parts of art. Lines, anatomy, colors, values, background, perspective, etc - figure out which part or parts you struggle with, and use one term at a time.

What types of videos are for me? If you are a Fresh Brand New Baby Beginner Artist that doesn’t even know much about art letalone art programs, then stick to tutorials that are labelled “for beginners”. If you know your way around an art program but you’re still pretty new, then your average art tutorial should be most helpful. More entertaining artists should be ok to start with! If you know your way around art but not programs, look for “art program reviews”, then once you’ve picked one or a few to mess around with (though I really recommend one at a time), look for “(program name) intro to / introductory”. And if you are well aware of everything I’ve listed, then you’ll be needing “intermediary / intermediate” tutorials. These ones are best given by master artists who focus on academic presentation. If you’re a master, you don’t even need this tumblr post wyd  😂

Tracking the Sun’s Cycles

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.

image

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.

image

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.

image

Measuring the solar cycle

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.

image

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.

HiPOD 20 Apr 2022: Recent Gullies In Equatorial Valles Marineris

HiPOD 20 Apr 2022: Recent Gullies in Equatorial Valles Marineris

Although actively-forming gullies are common in the middle latitudes of Mars, there are also pristine-looking gullies in equatorial regions.

In this scene, the gullies have very sharp channels and different colors where the gullies have eroded and deposited material. Over time, the topography becomes smoothed over and the color variations disappear, unless there is recent activity.

Changes have not been visible here from before-and-after images, and maybe such differences are apparent compared to older images, but nobody has done a careful comparison. What may be needed to see subtle changes is a new image that matches the lighting conditions of an older one. Equatorial gully activity is probably much less common—perhaps there is major downslope avalanching every few centuries—so we need to be lucky to see changes.

MRO has now been imaging Mars for over 16 years, and the chance of seeing rare activity increases as the time interval widens between repeat images.

Enhanced color image is less than 1 km across.

how to improve drawing kinda fast:

ditch lineart for a bit (this way its easier to part with things that aren’t working)

use a REALLY thin brush

copy, copy, copy art you think is ✨art goals✨

don’t post that stuff tho :O

if you need to trace at first, thats fine lol but break away from that eventually!! you gotta train your eyes to draw what you see, spatial awareness is very important

copy hands, poses, expressions, anything you wanna get better at

don’t copy from refs that are way too simple to be used as a “master study”, like from the calarts shows etc.

copy from stuff thats kinda complex bc if you learn how to draw it in that complex way, you can always simplify it if you want ^^

im pretty sure this is how many of us have become obsessed with hip dips details LOL

if something looks off, flip ur canvas, mess with ur sketch, or even delete (or hide) parts of the sketch and try again. if you drew it once, u can draw it again. (erase or hold up the page to the light backwards if drawing on paper)

being cool with parting with your sketch if its not working will make you a better artist

youre allowed to frankenstein refs together lol (a hand from here, a mouth from there…)

if youre having trouble making your sketches look like theres actual shapes, try shading :D

literally the only reason i shade now is to show the shapes of objects in more of a painterly way (its not just for paintings btw, its just easier to describe it that way)

try new things that youre excited about like perspective, anatomy, blah blah

copy!!!! while youre copying it’s gonna be cool to see how much you remember when you try it on your own

scribble a doodle as often as you can, not like urgently, but like as something to look forward to (like how lots of ppl look forward to wordle everyday lol)

this list can apply to anyone but its fine if you wanna take some advice and leave some if it doesn’t work out. this list is mostly just to get you comfortable with sketching and learning, not performing.

I mention that “not performing” thing bc its easy to want to please social media platforms because that attention and validation can feel amazing! 

but its also addicting because many of us crave being in a community and talking to ppl who like the same things we do

there are many communities out there from artist youtubers, artist streamers, etc. and many of them have discords and stuff and it might be fun to join! and/or join fandom ones if u want ^^ 

that way you have something thats not bound by if ig decides to not show your post to your followers or something

there’s also lots of other platforms that aren’t social media based specifically for artist communities too!

with this said, please be safe! never give out private info and you’re always free to block/report ppl who make u uncomfortable or ask weird things. 

on the topic of being in communities… reblog art you like! comment the nice things youre thinking in the tags or in an actual comment! share art you like on your ig story!

firstly, this is great for making friends

secondly, the artist cant read ur mind so they don’t hear anything nice youre saying :(

comments can be so motivating!! hearing nice things from my mutuals about my art feels great bc of that authentic human connection we’ve all been missing for like 2 years now

if i see a mutual drawing something and i think “omg they did amazing with the expression!” i write it (ive also been told i leave comments as if im talking and its kinda funny to read sometimes xD)

its channeling “girls support girls” culture in a way lol we’re our best when we’re lifting each other up <3

luv ya, be safe!! and draw lots of things!! :D

add stuff that’s helped you improve kinda fast if u want too! if we put all our brain cells together we’ll be unstoppable heheh

Your writing will always feel awkward to you, because you wrote it.

Your plot twists will always feel predictable, because you created them.

Your stories will always feel a bit boring to you, because you read them a million times.

They won't feel like that for your reader.

HOW DO YOU SHADE THE GOLD PARTSS???? PSLSPSLPSLPSLS

HOW DO YOU SHADE THE GOLD PARTSS???? PSLSPSLPSLPSLS

You don't have to take my word as gospel but these are the things I found that work well: ♡

(Please excuse grammatical errors I wrote this with a headache-...)

In my personal experience and process with gold, I find that these few things help me a lot when tackling it:

-whenever you approach gold it's important to asses the medium in which the material presents itself. The two options are the metal itself and any type of golden fabric.

-the shading process for me begins right from the sketch, when mapping out the gold accessory, object or the accent on a piece of clothing I try to get the shape of it to make sense.

HOW DO YOU SHADE THE GOLD PARTSS???? PSLSPSLPSLPSLS
HOW DO YOU SHADE THE GOLD PARTSS???? PSLSPSLPSLPSLS

It's most important, with golden fabric, to know and imagine how it falls arround and wraps arround a silhouette or body parts, if you want to figure out shading.

-So, when we speak "golden clothing" it revolves arround very sharp shadows, lights and reflections mainly becouse of fabric wrinkles. Golden clothing is pretty easy once you understand the nature of your material-☆

And the rules apply to any other colour!

HOW DO YOU SHADE THE GOLD PARTSS???? PSLSPSLPSLPSLS
HOW DO YOU SHADE THE GOLD PARTSS???? PSLSPSLPSLPSLS

Original Yellow hue

♡Same rules apply♡

So if you want you can structure your lights and shadows in black, white and grey! It works well to start off if you're not confident with colours as gold can be tricky in that regard...

GREYSCALE- can help you better understand the intensity of lights and shadows in contrast with one another:

HOW DO YOU SHADE THE GOLD PARTSS???? PSLSPSLPSLPSLS

You can then focus on colour later after you set up your values.

HOW DO YOU SHADE THE GOLD PARTSS???? PSLSPSLPSLPSLS

You'll notice with gold pieces that are much less clothing and much more metal the shadows alter from soft to sharp depending on the physical structure of the object itself.

If you encounter smooth curves it's soft, when it's sudden cuts or edges it's sharp.

Important to keep in mind:

-Gold is a metal = metals are REFLECTIVE.

HOW DO YOU SHADE THE GOLD PARTSS???? PSLSPSLPSLPSLS

Metals will reflect light aswell as colours.

They will especially reflect ☆colorful lights.☆

You must always, always, know where the light source is, and how it hits the object/ material.

That's it for now but if you want a more detailed step by step process just ask ^^☆

-Nix🌙
