"What it looks like from the space station when your best friend achieves her lifelong dream to go to space." 👩🚀 From orbit, astronaut Christina Koch (@astro_christina ) captured this photo of the second stage of the Soyuz spacecraft launch carrying Jessica Meir (@astro_jessica ) and two more space travelers: Oleg Skripochka of Roscosmos and spaceflight participant Hazzaa Ali Almansoori. The Soyuz docked to the @ISS today after a four-orbit, six-hour flight. Scroll through for more images of the launch!

Stuck on the rings 💍💍💍 From this perspective, icy moon Tethys appears to be stuck to the A and F rings of planet Saturn! This view from our Cassini spacecraft's narrow-angle camera, taken on July 14, 2014, looks toward the Saturn-facing hemisphere of Tethys. North on Tethys is up and rotated 43 degrees to the right.
Cassini launched in 1997 from Cape Canaveral Air Force Station in Florida and arrived at Saturn in 2004. NASA extended its mission twice – first for two years, and then for seven more. The second mission extension provided dozens of flybys of the planet's icy moons. Cassini explored the Saturn system for 13 years, finishing with "Grand Finale" dives between Saturn and its rings. The mission ended on Sept. 15, 2017.

The power of a supermassive black hole! 💪 An x-ray jet of high-energy particles — pointing to the upper left in this image — extends for 13,000 light years to the outer reaches of nearby galaxy Centarus A.
Astronomers think that such jets are important vehicles for transporting energy from the black hole to the much larger dimensions of a galaxy, and affecting the rate at which stars form there.
This @nasachandraxray image was made in 2008 from an ultra-deep look at the galaxy, equivalent to more than seven days of continuous observations.

Already feeling the Halloween spirit? 💀 This galaxy looks like it’s rising from the dead.
Messier 110 is an elliptical galaxy — a type of galaxy that’s often considered “dead” because it contains mostly old stars. But astronomers have spotted signs of a population of young, blue stars at the center of Messier 110, hinting that it may not be so “dead” after all.

Eons of erosion on Mars have formed the sweeping layers seen in this sedimentary rock located in Danielson crater, an impact crater located in the Arabia Terra region of the Red Planet.
This stereo image taken by our Mars Reconnaissance Orbiter allows scientists to measure the thicknesses of these sedimentary layers. The layer thicknesses and how they vary through time can provide some insight into the processes, possibly linked to ancient climate, that deposited the layers so long ago.

“Humanity glides by beneath us as we go screaming through the sky.” Astronaut Nick Hague captured this image from one of the windows of the International Space Station (@ISS ) as the orbiting laboratory moved around the Earth at ~5 miles (~8 kilometers) a second. He is now reaching the tail-end of his 200-day mission, with less than a month left until he returns to Earth.

"The living history of the Earth jumps out at you through buckles, folds, giant fans," wrote astronaut Nick Hague (@astrohague ) about his photo of the "Eye of the Sahara" from the International Space Station (@ISS ). Scroll through for more images of this striking geologic feature, the Richat Structure of Mauritania, captured by astronauts on the station and @NASAEarth satellites.
Located in the Sahara Desert, it measures 28 miles (45 kilometers) across and is made up of igneous and sedimentary rocks. It's thought to be caused by an uplifted dome that has been eroded to expose the originally flat rock layers.

Cloud formations over the Pacific! ☁️☁️☁️
An astronaut on the @ISS took this photo on April 4, 2019, while the station was traveling near the southernmost reaches of its orbit over the South Pacific Ocean. The striking colors within the cloud formation are a result of the local sunrise. When the Sun is at a low angle (relative to the atmosphere and the space station), sunlight passes through a thicker slice of the atmosphere. This can enhance the red end of the visible color spectrum, leading to the pink hues visible at the center of the image.
The astronaut who took this photograph sent a message to ask if this specific cloud formation had been a named tropical cyclone. However, because the weather system was short-lived, the storm dissipated before making landfall, and thus was not named.

Saturn is so beautiful that astronomers cannot resist using the @NASAHubble Space Telescope to take yearly snapshots of the ringed world when it is at its closest distance to Earth. 😍
This image, however, is more than just a beauty shot. It reveals exquisite details of the planet as a part of the Outer Planets Atmospheres Legacy project to help scientists understand the atmospheric dynamics of our solar system's gas giants.

A galaxy so faint you can barely see it ✨
@NASAHubble Space Telescope recently caught a glimpse of a galaxy 30 million light-years away. UGC 695 has so few stars that its brightness is less than the background brightness of Earth’s atmosphere — making it difficult to observe. Thankfully, Hubble managed to take a peek for us.

No, this isn’t a firework. 🎆 You are looking at a flame and the glowing soot clusters it produced aboard the International Space Station (@ISS ). These yellow soot clusters grow larger than those on Earth, because they stay inside the flame longer in microgravity.
This flame was one of many ignited inside a combustion research facility to investigate the amount of soot that is produced in different conditions. Soot is the carbon residue left behind when organic matter (or other carbon-containing material) doesn’t fully burn. It causes environmental and health issues, but can be helpful in multiple ways, including by enhancing radiant heat.
This experiment could allow the design of flames that are more sooty or soot-free. These results may help create burner designs which are more efficient and less polluting.
