The oldest depiction of the universe

This is one of the most important archaeological finds of the 20th Century and the oldest depiction of the universe so far. Called the Nebra sky disc, named for the town where it was found in 1999, the artifact has been dated back to 1600 BC. It was buried about 3,600 years ago but could be much older. It has been associated with the European Bronze Age Unetice culture.

When it was first crafted, it would have been golden brown because the disc itself is made from bronze. Over time, the it corroded to green. Fortunately, the symbols are made of gold and thanks to them we know it was possibly an astronomical instrument.
There’s Sun, a central to northern European Bronze Age religion and the crescent moon (in ancient times, the moon was used to represent time). The clump between the sun and moon are thought to be the Pleiades constellation, which was an imporant constellation for Bronze Age farmers because it appeared and disappeared in important farming times. So the Nebra disc could have told people the right time to plant and harvest.

What’s more, astronomer Wolfhard Schlosser, at the University of Hamburg, found that if you draw a line from the center of the disc to the top and bottom end of the right arc, the angle between the two ends measures exactly 82 degrees. And it’s the same value for the left golden arc. This number is very important for only a small group of people who live at the same latitude as the current German town of Nebra since it’s the angle between where the sun sets on the horizon in mid-winter and mid-summer.

The bronze disc combines an extraordinary comprehension of astronomical phenomena enabling to peak into the early knowledge of the heavens. It’s   shocking it was almost lost to the black market.

The Milky Way over Western Australia

“The Milky Way behind a silhouette of gum trees near Lake Leschenaultia in Mundaring, Western Australia. This location almost borders the Perth metropolitan area so I was a bit surprised at how dark the skies were there. This particular shot was a spur of the moment decision as I was about to put all my gear back into my car after doing a large panorama at the nearby lake.”

Milky Way through the Clouds

This was shot at Harvey Dam approximately 125km south of Perth in Western Australia.

“This one was a near disaster. I drove 125km to this location only to be thwarted by cloud cover. My first thought was to get back in the car and head home but I decided to go ahead and keep shooting in the hope it would clear by the time I got to the more interesting bits and thankfully it did.”

“The Hoya red intensifier filter gives the clouds their colour and also makes some nebula stand out including the Carina Nebula on the right side of the image. A mining operation a few km away is the source of the light reflecting off the clouds in the middle. As always, the Large Magellanic Cloud is prominent near the bottom right.”

Hi, I need a little help. I'm 16 and few months ago started being interested in astronomy. I haven't made a big progress since then, because I don't know where to start. I'm quite good at maths, not so "strong" at physics, but I don't have lot of problems with this subject. What and where should I learn at first? (I started "brief history of time", found "crash course" and csuDH course, but didn't start them). My knowledge of astronomy is very very low, so I'd be thankful for your advice!

Hello!
16 is a perfect time to start thinking about options in astronomy. Actually that was approximately the time I started to realize that astronomy/astrophysics is something I want to do in the future. :)

PLAN YOUR FUTURE! 

First of all - congratulation! You´ve already started! :) You need to have an idea about what would you like to do in the future. If it is an astronomy field - excelent! Now, next step is to know your options - I don´t know where are you from, but I guess there is a university nearby which is offering a study of astrophysics. Mostly studying astrophysics at university requires GCSE or graduation in mathematics and physics and good school results - but you need to find out by yourself, because every educational system is quite different and I don´t know how it goes in your country.
After you choose a university you want to study in, you should do next step which is realizing what are your options after you´ll finish university. I recommend you this website —> here <— you can read something about how to plan your education in astronomy/astrophysics and some tips. —> here <— is a website where many astronomers/astrophysicists are looking for jobs.  Also you can check this site —> here<— where you can find another list of jobs in this field


(I´ve answered similar questions not long time ago, so you should check it out >> here << and >> here << ) 


GET INTO IT!

The fun way to learn something about a field of astronomy is to check out astronomy websites…These are my favourite:
NASA 
Space.com
ESO
CERN
New Scientist
Physics-Astronomy

If you prefer something more personal, try these books:
(These are not hard to understand and they will help you in the beginning)
The Fabric of the Cosmos: Space, Time, and the Texture of Reality 
The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory
The Book of Constellations: Discover the Secrets in the Stars
The Physics Book: From the Big Bang to Quantum Resurrection, 250 Milestones in the History of Physics (Sterling Milestones)
Pale Blue Dot: A Vision of the Human Future in Space
Cosmos
NightWatch: A Practical Guide to Viewing the Universe

If you don´t have energy or if you are not in the mood for reading, try these documentaries:
How the Universe Works
~ The Universe (TV series)
Known Universe
~ Cosmos: A Spacetime Odyssey
~ The Age of Hubble
~ The Year of Pluto

I also derive benefit from youtube videos…you can find many documentaries there and also many astonishing animations, tutorials and even whole lectures which can help you with better understanding math/physics/astronomy problems.

~ Physics lectures
~ Math lectures
~ Astronomy animations
~ Astronomy documentaries

SOME CONCLUSION

It is important to know your options. Another important thing is to make contacts with people who know things you do not know yet. The next step is to choose what you want to achieve in the future and ensure a procedure which will get you there. Self-education is necessary :)

Don´t worry, you will get there, but it takes time and work!

In ancient Greece the study of astronomy was linked to the same physical principles as musical harmony.  For example, many Greek thinkers believed that each of the planets and stars created their own unique sound as they traveled through the cosmos, thrumming like an enormous guitar string light-years long.
