The Sun completes one rotation every 25 days.
“The sun is the nearest star: a glowing sphere of gas, shining because of its heat, like a red-hot poker. The surface we see in ordinary visible light is at 6 thousand degrees centigrade. But, in its hidden interior, in the nuclear furnace where sunlight is ultimately generated, its temperature is 20 million degrees. All this churning power is driven by the sun’s interior which is converting 400 million tons of hydrogen into helium every second. The sun is a great fusion reactor into which a million earths would fit. Luckily for us, it’s safely placed 150 million kilometers away.
Plants harvest sunlight, converting solar into chemical energy. We and the other animals are parasites on the plants; so we are, all of us: solar powered. The evolution of life is driven by mutations; they’re caused partly by natural radioactivity and cosmic rays, but they are both generated in the spectacular deaths of stars thousands of light years distant.
Think of the sun’s heat on your upturned face on a cloudless summer’s day: from 100 million kilometers away, we recognize its power. What would we feel on its seething, self-luminous surface, or immersed in its heart of nuclear fire? And yet, the sun is an ordinary, even a mediocre star. Our ancestors worshipped the sun and they were far from foolish. It makes good sense to revere the sun and the stars because: we are their children.”

My boyfriend made this for me…
does it make us look more animal or animals more human?
favourite thing ever
wow you can practically see the animal in the human, and the human in the animal
Since Human is a kind of animal, I’d say it shows that we are more animal and less important or special/unique than we make ourselves think.
Plenty of people like to say “what’s the point of changing your picture? It doesn’t do anything.” But it does. As much as we all hate to admit it, Facebook is a big part of our lives. We spend hours all day looking at it. Obviously changing our profile picture isn’t a way to convince policies and laws to change, but it is a way to show people who are struggling with marriage equality that you are there to support them. I am an ally, and I am here for support. I’m using this symbol as a way for anyone who recognizes it to know where I stand. You will look at this picture and it will instantly let you know that I support you, I want you to be happy, and I want equality. I know people need support in these times, and this is a way to show it.
