Can you guess the subject of each of these pictures? How many will you get right? Test your friends and family to see who knows their space photos the best.
1. Mars. You might be surprised, but this image taken by our Mars Reconnaissance Orbiter is of a light-toned deposit on the Martian surface. Some shapes in the terrain suggest erosion by a fluid moving north to south.
2. Earth. This image taken by our Earth Observing-1 satellite shows Lake Frome in central Australia. In this image, the salt lake appears bone-dry, filled with off-white sediment. This area of Australia receives 149 to 216 millimeters of rainfall a year on average, and the basins pass most of their time as saltpans.
3. Mercury. Our MESSENGER spacecraft captured this image of Mercury during a fly by in October 2008. It shows previously uncharted regions of the planet that have large craters with an internal smoothness similar to Earth’s own moon. It is thought that these craters were to have been flooded by lava flows that are old but not as old as the surrounding more highly cratered surface.
4. Earth. Surprisingly, this image take from the International Space Station shows the western half of the Arabian peninsula in Saudi Arabia. It not only contains large expanses of sand and gravel, but extensive lava fields known as haraat.
5. Saturn. Although this pattern of waves is similar to those seen on Jupiter, this is actually a picture of Saturn. The pattern of an iconic surfer’s wave, has been observed in many places all over the universe, including at the edges of Earth’s magnetic environment.
6. Mars. This image was taken by our Mars Reconnaissance Orbiter and shows dunes of sand-sized materials that have been trapped on the floors of many Martian craters. The dunes are linear, thought to be due to shifting wind directions.
7. Left: Europa. Right: Frying Pan. Europa is one of Jupiter’s moons, and is about the same size as Earth’s moon.
8. Ceres. This image taken by our Dawn spacecraft shows an intriguing mountain on dwarf planet Ceres protruding from a relatively smooth area.
9. Earth. This image of the Bazman volcano is located in a remote region of souther Iran. While the volcano has the classic cone shape of a stratovolcano, it is also heavily dissected by channels that extend downwards from the summit.
10. Earth. This image of the Great Sandy Desert in northwest Australia shows a variety of dune forms across the region. The photo was taken by the Expedition 35 crew from the International Space Station.

Your asexuality is not something you should be ashamed of. Your asexuality is not something that you should regret because of how it might affect your relationships. Your asexuality is not bad, regrettable, or shameful.
“sex is great” but have u ever
cracked your back and it feels like sleeping on clouds
heard that one chord in a song that just resonates with your soul
bit into pizza and it doesnt burn your tongue its just warm and yummy
drunk some hot chocolate and the marshmallows have melted perfectly
tucked a lock of hair behind your ear and it stays
breathed in deeply and then exhaled and felt that everything was ok
had someone lean their head on your shoulder absentmindedly
made your friend giggle
realized you had all the ingredients and time for your favorite food
gotten into bed, felt like you’re floating, and fallen asleep immediately
The sun is a star, a hot ball of glowing gases at the heart of our solar system. Its influence extends far beyond the orbits of distant Neptune and Pluto. Without the sun’s intense energy and heat, there would be no life on Earth. And though it is special to us, there are billions of stars like our sun scattered across the Milky Way galaxy.
If the sun were as tall as a typical front door, the Earth would be the size of a U.S. nickel
The temperature at the sun’s core is about 27 million degrees Fahrenheit
Our sun is more massive than the average star in its neighborhood. Nearly 90% of stars are less massive, making them cooler and dimmer
The sun contains 99.9% of all matter in our solar system
During a single second, the sun converts 4 million tons of matter to pure energy
It would take about 1 million Earths to fill the sun if it were a hollow ball
The sun rotates on its axis approximately once every 27 days
The sun is 93 million miles away from Earth and is almost 5 billion years old
