Europe, moon in the orbit of Jupiter, is one of the most interesting places in the solar system. Under its thick crust on the ice, the moon has an ocean layer that holds more water than we have here on Earth, making it a prime venue for seeking life outside of our planet. These two global photos of Europe show large regions that look yellow – a coloration caused by sodium chloride, better known as salt. Findings based on spectral analysis of visible light from the Hubble Space Telescope show that large areas of the surface are also covered with ordinary, old salt. We know that the ocean of this moon contains some chemical salt, but the fact that it is the salt that is in our seas raises the intriguing potential that there may be life.
These are the golden years for the galaxy. NGC 7773. Hubble has captured this spiral in great detail and you can see a phenomenon that occurs in older galaxies: the star belt in the middle. Astronomers believe that this function, which distinguishes helix spirals, takes shape later in the life of the galaxy, as the star material gravitates to the center of the stars, gas, dust, and dark matter. NASA's Fermi Gama Beam Telescope has not yet found gamma rays with the highest energy. The green points of this color map in the sky show where Fermi's instrument has detected these outbursts of radiation. (The galactic plane of our Milky Way passes by the center.) Scientists are still trying to understand more about these gamma rays, which only happen as a result of the most violent events, such as when a massive star turns into a supernova, or when two neutron stars collide and create a black hole.
NASA's Stratospheric Observatory for Infrared Astronomy explores the massive black hole in the center of our Milky Way in the infrared spectrum. This image shows the black hole along with the magnetic field lines; as the surrounding material is sucked in, the dust particles and the gas are heated and passed through these lines, which are fired in infrared light. By studying these lines of the magnetic field, astronomers can better understand how matter and black holes interact. They are not as worried about the absorption of our world, as the black hole of the Milky Way is not as active as those in the center of most other galaxies. And why is that? Another good question for the researchers and for SOFIA.
If you've ever invested money in nail machines in an arcade, you understand how difficult it is to insert a plush toy from the glass container. Imagine manipulation of the nail on another planet is millions of miles. For NASA's InSight, such exploits are part of the cake: In February, the Cabinet released its tools on the Martian surface. Here we see the clinging of the probe's fingerprint to the heat flow that will absorb the inner temperature of the red planet.
Mars has a long side: These characteristics in the area of Cerunius Fossae are deviations, known as grabbing. They are created when the earth crust extends and splits, allowing the material to descend along the fracture. You can even say about the bitterness of all but the ex-scientists that the dirt on Mars is a robbery on the ground.
