Happy Martian Summer Solstice! (for you Northern Hemisphere Martians)
Quick Facts About Mars:
1) Since Mars has only 15% of Earth’s volume, Martian gravity is only 37% of the Earth’s. Meaning you could jump 3x higher on Mars than on Earth.
2) In this particular image you can see the BIGGEST volcano in the Solar System. This beast is 21 km high (compared to Mt. Everest’s 8 km) and a whopping 600 km in diameter. Even though this volcano formed over billions of years, many scientists believe this volcano is still active.
3) Average temperatures on Mars is about -60 degrees C or maybe you rather be closer to the equator where it’s about 20 degrees C! It also snows on #Mars!

Can you see the shape of a hand in this new X-ray image?
The hand might look like an X-ray from the doctor’s office, but it is actually a cloud of material ejected from a star that exploded. NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, has imaged the structure in high-energy X-rays for the first time, shown in blue. Lower-energy X-ray light previously detected by NASA’s Chandra X-ray Observatory is shown in green and red.
Nicknamed the “Hand of God,” this object is called a pulsar wind nebula. It’s powered by the leftover, dense core of a star that blew up in a supernova explosion. The stellar corpse, called PSR B1509-58, or B1509 for short, is a pulsar: it rapidly spins around, seven times per second, firing out a particle wind into the material around it – material that was ejected in the star’s explosion. These particles are interacting with magnetic fields around the material, causing it to glow with X-rays. The result is a cloud that looks like an open hand. The pulsar itself can’t be seen in this picture, but is located near the bright white spot.
