This just in, NASA’s study published today reveals that they’ve found liquid water on Mars. It’s confirmed.

This is what our night sky could look like guys.

NASA took over the White House Instagram today in honor of Astronomy Night to share some incredible views of the universe and the world around us. Check out more updates from the astronauts, scientists, and students on South Lawn.
Here’s a nighttime view of Washington, D.C. from the astronauts on the International Space Station on October 17. Can you spot the White House?
Check out this look at our sun taken by NASA’s Solar Dynamics Observatory. The SDO watches the sun constantly, and it captured this image of the sun emitting a mid-level solar flare on June 25. Solar flares are powerful bursts of radiation. Harmful radiation from a flare can’t pass through Earth’s atmosphere to physically affect humans on the ground. But when they’re intense enough, they can disturb the atmosphere in the layer where GPS and communications signals travel.
Next up is this incredible view of Saturn’s rings, seen in ultraviolet by NASA’s Cassini spacecraft. Hinting at the origin of the rings and their evolution, this ultraviolet view indicates that there’s more ice toward the outer part of the rings than in the inner part.
Take a look at the millions of galaxies that populate the patch of sky known as the COSMOS field, short for Cosmic Evolution Survey. A portion of the COSMOS field is seen here by NASA’s Spitzer Space Telescope. Even the smallest dots in this image are galaxies, some up to 12 billion light-years away. The picture is a combination of infrared data from Spitzer (red) and visible-light data (blue and green) from Japan’s Subaru telescope atop Mauna Kea in Hawaii. The brightest objects in the field are more than ten thousand times fainter than what you can see with the naked eye.
This incredible look at the Cat’s Eye nebula was taken from a composite of data from NASA’s Chandra X-ray Observatory and Hubble Space Telescope. This famous object is a so-called planetary nebula that represents a phase of stellar evolution that the Sun should experience several billion years from now. When a star like the Sun begins to run out of fuel, it becomes what is known as a red giant. In this phase, a star sheds some of its outer layers, eventually leaving behind a hot core that collapses to form a dense white dwarf star. A fast wind emanating from the hot core rams into the ejected atmosphere, pushes it outward, and creates the graceful filamentary structures seen with optical telescopes.
This view of the International Space Station is a composite of nine frames that captured the ISS transiting the moon at roughly five miles per second on August 2. The International Space Station is a unique place—a convergence of science, technology, and human innovation that demonstrates new technologies and makes research breakthroughs not possible on Earth. As the third brightest object in the sky, the International Space Station is easy to see if you know when to look up. You can sign up for alerts and get information on when the International Space Station flies over you at spotthestation.nasa.gov. Thanks for following along today as NASA shared the view from astronomy night at the White House. Remember to look up and stay curious!
One Last Look At The Space Shuttle Endeavour’s Cockpit Before It’s Shut Down Forever
Rocket engine exhaust often contains a distinctive pattern known as shock diamonds or Mach diamonds. These are a series of shock waves and expansion fans that increase and decrease, respectively, the supersonic exhaust gases’ pressure until it equalizes with atmospheric pressure. The bright glowing spots visible to the naked eye are caused by excess fuel in the exhaust igniting. As awesome as shock diamonds look, they’re actually an indication of inefficiencies in the rocket: first, because the exhaust is over- or underexpanded, and second, because combustion inside the engine is incomplete. Both factors reduce a rocket engine’s efficiency (and both are, to some extent, inescapable). (Photo credit: XCOR)
