down and up. low and high. ground and sky. leaves and clouds. red and blue. green and white. they hold both the important and unimportant memories of our lives. even beyond the sky, out there in space, we make memories and will continue to make new ones.
Breathtaking Self-Portraits Under Finland’s Northern Lights
“I was so impressed with the loneliness, the air and the silence. Out there you feel so small because there is only cold and ice.” - Photographer Tiina Törmänen
my heart. it wants to go there and just stay there. the beauty. so dreamy.
The upper atmosphere of the Sun is dominated by plasma filled magnetic loops (coronal loops) whose temperature and pressure vary over a wide range. The appearance of coronal loops follows the emergence of magnetic flux, which is generated by dynamo processes inside the Sun. Emerging flux regions (EFRs) appear when magnetic flux bundles emerge from the solar interior through the photosphere and into the upper atmosphere (chromosphere and the corona). The characteristic feature of EFR is the Ω-shaped loops (created by the magnetic buoyancy/Parker instability), they appear as developing bipolar sunspots in magnetograms, and as arch filament systems in Hα. EFRs interact with pre-existing magnetic fields in the corona and produce small flares (plasma heating) and collimated plasma jets. The GIFs above show multiple energetic jets in three different wavelengths. The light has been colorized in red, green and blue, corresponding to three coronal temperature regimes ranging from ~0.8Mk to 2MK.

Watching the Sunsets of Mars Through Robot Eyes
Watching a sunset on Earth can be a dazzling and beautiful natural wonder. But what about sunsets on other worlds?
Situated over 50 percent further away from the sun than Earth, there’s one planet that we’ve also had the fortune to see the sun drop below the horizon while standing on the surface – Mars. However, we have yet to experience this Martian perspective with our own eyes; instead we depend on images beamed to Earth after being witnessed by robotic lenses and CCDs from NASA’s landers and rovers.

A Martian Sunrise - Daybreak at Gale Crater
Gale Crater can be seen in the center of this image with its central mountain of Strata. This is the Crater where NASA landed the Curiosity Mars Rover and made history in 2012. Curiosity discovered that this crater was once at the bottom of a large freshwater lake. The water in this lake would have been drinkable by humans and hospitable to microbial life. After exploring the Crater, Curiosity proceeded to explore the nearby plains of Aeolis Palus in search of life. Curiosity continues its search today, 140,000,000 miles away from home on a planet inhabited entirely by robots. (Though this image is computer generated, all of the geological features are correct and realistic.)

The mathematician Archimedes once said, “Give me a place to stand, and I shall move the Earth.” As it turns out, he was describing the fundamental principle behind the lever.
These hundred million of stars are JUST a part of Andromeday galaxy, and almost all of those stars have their own systems, their own orbiting planets. Now, imagine how many stars are there in one galaxy (approximately a hundred billion) then multiply it by the average number of planets a star has, let’s say it’s 5, then multiply it again by the number of galaxies in the known universe, which is approximately a hundred billion. That’s hundred billion x hundred billion x 5. Then, tell me, is it impossible to have another life forms (simple or complex ones) outside our planet? Hmmmm.

This image of the Earth, also known as the Pale Blue Dot, was taken when the Voyager 1 spacecraft reached the edge of the solar system on February 14, 1990. It has been 24 years!! HAPPY VALENTINE’S DAY! <3

Reblogging this just because. =)) The most humbling picture I’ve ever seen.
