Science related Art Week

A Brief History

From the beginning of civilization, the study of the sky has been a constant theme. Some scientists even claim that the prehistoric paintings of the Lascaux Cave are in fact depictions of constellations. True or not, astronomy is definitely one of the oldest sciences, if not the oldest.
For centuries, maps of the sky and the universe were created, most of them with a religious idea in mind.
Aside from the spiritual aspect of astronomy in the Occident, stars are also used for sea navigation. The Arab civilisation is at the origin of many star names and precise measurements of star positions.

Picture via wikipedia :…

At the renaissance astronomy was progressively separated from astrology and religion (not without difficulties). The invention of the telescope was critical to some of the most important discoveries of the renaissance.
With the invention of the telescope, the sky became even more impressive, and with the development of science and technology telescopes are becoming larger and larger.
The most famous telescope is probably Hubble. We are all familiar with incredible pictures like the pillar of creation.

But do you know where the colours come from, and if they are the real colours of the sky ?

The Hubble Pallette

If you thought that the beautiful colours from Hubble pictures are real, I'm sorry to destroy your dreams, but they are in fact false colours. Astronomers use the light to analyse the composition of stars and nebulae, and extract specific light rays showing the presence of a particular elements. These pictures are called narrowband images. By affecting these narrowband images at specific RGB channels, they can create the colour they want.
Here is an example of a Hydrogen Oxygen Nitrogen false colour picture.

  Red = Hydrogen                  Green = Oxygen                        Blue = Nitrogen

Resulting HON picture

Pictures via : Almaden Observatory
The choice of colour can be decided by a scientific use : the picture has a visual composition information, but it is also the result of a personal choice and picture beauty. Hubble astronomers are also artists in their job.
If you want to create your own images using this technique, a software is available as a plug-in for photoshop.…

The Night Sky

No need to have the budget of NASA to make pictures of space. A simple camera can create very impressive pictures of our galaxy and an amateur telescope can show nebulae in their full glory.

Space Art - The Intersection

Space art is somewhere in between science and science fiction. It is often used to illustration science articles. Space art is at present time the only way we have to visit our universe.

Galileo Galilei: The Starry Messenger

Fri Feb 13, 2015, 4:20 PM
Img-og by techgnotic

February 15 marks Galileo’s 461st birthday.

The man has a long list of accomplishments in the field of astronomy attributed to his name, including improving and developing the telescope, discovering sunspots, and proving that earth was not the center of the universe.

One of Galileo’s most widely-known accomplishments is the discovery of Jupiter’s four largest moons, also known, aptly, as the Galilean Moons. Their names—Ganymede, Io, Callisto, Europa—are widely known, but the consequences of their discovery are more significant than you might think. Because Galileo was an early developer of the telescope at a time when the science of astronomy was experiencing radical progress, he sometimes had the luxury of pointing his spyglass skyward and stumbling on a previously undiscovered object. To wit, the astronomer actually observed Neptune in 1612 and marked it in his notes as an insignificant, dim star. And while you can imagine Galileo’s initial discovery of these moons as being similarly haphazard, he quickly realized something significant had happened.

Upon his first observation, three of the Galilean Moons were arranged in a straight line extending outward from Jupiter.

Not altogether unremarkable in a sky full of bright objects, but it was the first indication that there was something unique about these spots. “Three fixed stars, totally invisible by their smallness,” Galileo remarked in his initial notes. After observing these objects on subsequent nights, he realized that their positions were changing relative to Jupiter, in ways that did not make sense for "fixed stars.” Within days, he realized that the three spots he initially observed were orbiting Jupiter, and that there was indeed a fourth object moving in conjunction with the others.

It’s an interesting enough discovery, but it was also inevitable. In fact, another astronomer, Simon Marius, working independently of Galileo around the same time, also discovered these moons and gave them the names we know them by today (Galileo had initially named them “The Medicean Stars” in honor of his patron-to-be).

The reason that this discovery really altered the course of astronomy is twofold.

The first is that it disproved once and for all old Aristotelian notions about the cosmos. Aristotle believed that every object in the night sky orbited around the earth, and Jupiter’s moons were the first objects to be observed not following this pattern of behavior. The second reason is that it would set Galileo down a path toward acceptance of the heliocentric model of the universe (i.e., the Sun being the center of the universe), which famously led to him being tried and found guilty of heresy, besides influencing a great deal of his later work.

These dual pillars of significance are actually parts of the same idea on a deeper level. Old notions about the universe (including geocentricism) emphasized the importance of the earth, and led people to believe that they were at the center of the universe. The fact that Jupiter had a few moons rotating around it did not directly contradict the geocentric model, but it laid a framework for a more holistic way of thinking about the cosmos. That is, it exposed the scale of our universe as being something much larger and more complicated than our own planet or even our own solar system. Carl Sagan famously pointed to a photo of the earth sent back from the Voyager 1 in which the earth appears no larger than a pixel. He described our planet as a “pale blue dot,” the significance of which, if any, was dubious. Galileo opened the door to this line of thinking, and allowed us to begin seeing the universe as something bigger and more mysterious than just our corner of the neighborhood.

Your Thoughts

  1. Galileo avoided being burned at the stake (for claiming the Earth orbited the Sun) by recanting his scientific observations and spending the last nine years of his life under house arrest. Have we greatly advanced in our debating skills over the past 400 years, or is violence still too prevalent as a form of “dissenting opinion?”
  2. Humanity once thought the universe was only what could be seen in the night sky. Does the vastness of the universe we know today make you feel we are insignificant? Or does it fill you with wonder over what miracles and possibly what other life forms may be out there in that vastness?
  3. Do you welcome announcements of new scientific discoveries and get excited at the prospect of new discoveries always bringing a clearer picture of reality into focus? Or do you fear new science will ruin comfortable traditional ways of thinking?

Astronomy Photographer of the Year 2013

Journal Entry: Wed Jul 17, 2013, 5:23 AM

Aurora Brutality has just gotten on the shortlist of the Astronomy Photographer of the year 2013 competition, which means that I will get an invite to the exibition at Royal Observatory Greenwich in London where the winner of each category will be revealed and finally theoverall winner which can crown themself with the coveted title.

This image is on the shortlist in the category "Earth and space", so it has to go through there and be the overall winner to take everything home.

Personally I am very honored to be on the shortlist with such caliber of photographers, and it also fuels the fire to continue to try achieve as good results as I
possibly can with the camera.

Wish me luck, and have a superb day. :bow: :boogie:

Ok, so, i went town with my friend and went into this shop and whilst she bought some stuff i found a small book on Astronomy. I've always been interested in it and i love camping and sitting out under the stars. Me and a friend usually sit outside at night, when camping, and watch the sky, waiting for something to happen. well one night something did, we where sitter there, and just starring up at the night sky, just chatting about how amazing it is and how small we felt, then this realy bright shootin star shot right across the sky. it was visible long enough for us to sit up and gasp at the exact same time XD, we sat there, starrin in absalute unbelief untill somthing in us finally snapped and we just looked at each other and jumped up and ran to my caravan, where the perents where, and ran to my friends dad (hid dad knows quite a bit about stars and stuff) and startin ranting on about it, i dont think any one could understand us :D Any hoo, i was so amazing.

So, ever since i got this book, i cant seem to put it down and i cant seem to stop thinking about it. I realy realy realy want to see a comet and a meteor shower and the book tells me when they occur. last time there was a metoer shower (or last time i remeber one happening) was last year and i was in the most perfect place to watch it, far from lights in the middle of a field, the people who owbed the caravan site had turned all the lights off so that and everyone else could watch it...but alas...i fell asleep, completely oblivious it was happening untill the next day when people told us. ARRRRRG, i was (and sill am) so pissed off i missed it. i also missed a lunar eclips that i could of seen from my flippin bedroom window. DAM YOU SCHOOL!. if i had one wish right now, it would be to go into space, maybe visit the ISS (international space station) and go to the moon. I dream of being able see to earth from the moon, lookin at my home planet as if IT was the moon :icondreamplz: i also want a telescope, (i wonder if my perents would let me buy one?)

of and ps. if you have had any experienses like comets, eclipses, shooting stars ect, please feel free to shar them ^^ or just anything spacy you wanna share :hug:

Okay, I don't like to make journals like these since I would rather stay away from conflict.  But as of late, this so-called "war" that's between going on between an online friend of mine and other Deviants that I don't really talk to is starting to irritate me to no end and it's giving me a headache whenever I'm on here and I see some sort of update on that issue.  I've tried to keep silent about this issue but I feel I'm about to lose it anytime soon.  So, now I feel I have to speak my mind on this topic.

Look, I understand that stealing artwork is wrong, that stealing in general is wrong.  You can show me ALL the evidence that she's been doing this and I will acknowledge that it is not right.  However, that does not give you the right to post numerous journals just to prove your point that she's a thief and needs to take it down.  You can just privately tell her to remove the pics and to remind her to credit the person, whose base she's using, in the description and you should only have to do it ONCE.  I still don't see why you guys have to make such a huge deal out of this.  If it doesn't work then just ignore it and mind your own business, it's not like it's physically hurting you or anything.

And then you guys have the audacity, the NERVE, to occasionally make fun of her grammar? Really? Since when do you have the right to judge her for her grammar? I've seen some things you've written and clearly you don't have proper grammar either.  How do you expect me to take you seriously if you incorrectly capitalize or misspell some words? I'm far from perfect but it just bugs me if there's so much grammatical errors and you're trying to get your point across.

Oh, you just discovered that she's underaged? Okay, what of it? It's not like lying about your age on the internet is uncommon.  For all I know, you and I could be lying about our age and personal details since we're really just people behind computer screens typing words that may not be true.  And if she really is underaged like you claim she is, then you who claim to be adults or in their 20's clearly aren't dealing with this issue in a mature manner.  The journals and comments you make just screams "childish" to me.

You say that dumb, stupid people believe her lies.  So just because I'm her friend that doesn't agree with the art stealing, yet doesn't agree with what you're saying, it means I'm stupid? I fail to see the logic in that statement.  I'm pretty sure that's not what you're trying to say but you really need to be careful with your comments or else people can, and will, take it the wrong way.

So to all the people who are actively writing journals, making comments, and noting my friend just to get her to admit that she's wrong and to take down the stolen artwork, I'm going to tell you this.  Please stop and just leave her alone.  Yes, she's made mistakes like any human being would.  But that's all I see.  The only reason I see her attack you guys is because you give her that opportunity to do so, and you don't have to respond to it.  I don't see how what she's done equates to public advertisement to get others to hate her.  And over all, NONE of you have the right to decide whether she can or can't be on this site.  I absolutely hate it when I come on here and find out that there has been updates on this "war." It takes away my enjoyment of being on here for the sake of looking at other people's artwork and talking to my friends.

What you guys see as bringing an art thief to justice, I see as needless and overly excessive harassment. 

If you want to talk to me about this, note me and I will be more than happy to discuss this in a more civil manner.  If you're angry and defensive about what I just wrote, then go whine/complain to someone who gives a damn about your hurt feelings.  I'll just see it as you throwing a tantrum simply because you're not getting your way.

If you're entitled to your opinion, then I'm entitled to mine.  That is all.

29-The shape of the universe looks a lot like a brain cell.
30-Every year, the Moon is moving away from Earth by 3.8 centimeters.
31-The Moon spins around its axis in the same time it goes one lap around the Earth which makes us always see the same side of it.

48-The odds of being killed by falling space debris is 1 in 5 billion.
49-Neutron stars can rotate up to 500 times in 1 second.
50-The largest structure found in the universe is the Sloan Great Wall, a super cluster of galaxies 1.37 billion light-years wide.

Number 20 is quiet alarming, that's why I italicized and underlined it. Although, it's not surprising because most people see stars as those tiny points of light that we see in the night sky, rather than the big hot balls of plasma that gives off light and heat :/

The Astronomy Photographer of the Year competition kicks off its annual global search for the best and most spectacular visions of the cosmos, whether they are striking pictures of distant nebulae or dramatic images of the night sky.
