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. Credit: NASA #flame #space #microgravity #heat

Look! A cosmic block party 🥳 ⁣ ⁣ In this Hubble image, you’ll find 50 spiral and dwarf galaxies hanging out in our cosmic neighborhood. ⁣ ⁣ The main focal point of stars is actually a dwarf galaxy. Dwarf galaxies often show a hazy structure, an ill-defined shape and an appearance somewhat akin to a swarm or cloud of stars — and UGC 685 is no exception to this. ⁣ ⁣ These data were gathered under Hubble’s Legacy ExtraGalactic UV Survey (LEGUS ) program, the sharpest and most comprehensive ultraviolet survey of star-forming galaxies in the nearby universe. ⁣ ⁣ Image Credit: ESA/Hubble & NASA; the LEGUS team, B.

The final stages of a star’s life allow us a glimpse into the future of our own solar system. 🌟 ⁣⁣ ⁣⁣ This image from @NASAHubble shows what’s left of a star 10,000 light-years from Earth. ⁣⁣ ⁣⁣ A star like our Sun will, at the end of its life, transform into a red giant. The core of the star will eventually collapse in on itself, ejecting the surface layers outward. After that, all that remains of the star is what we see here: glowing outer layers surrounding a white dwarf star. ⁣ ⁣ Click the link above for more info ⬆️⁣ ⁣⁣ Image credit: ESA/Hubble & NASA, R.

🌀As Hurricane Dorian continues its move towards land, satellite missions from NASA and @NOAA are keeping an eye on the storm from space. After brushing past Puerto Rico, the storm began intensifying over open waters. On Aug. 29, forecasters noted: “Strengthening is forecast during the next few days, and Dorian is expected to become a major hurricane on Friday, and remain an extremely dangerous hurricane through the weekend.” Seen here is a composite image of the strengthening storm from the GOES-16 satellite. This simulated natural color image comes from the weather satellite’s Advanced Baseline Imager. GOES-16 is operated by the National Oceanic and Atmospheric Administration (NOAA ).

What remains after a star explodes 💥 ? A brightly glowing field of debris, expanding outward into space.⁣ ⁣ This supernova remnant, Cassiopeia A or Cas A, was imaged by our Chandra X-ray Observatory ( @nasachandraxray ). It's located about 11,000 light years from Earth and was also featured in Chandra's "first light" image at the start of the mission in 1999. This recent study of Cas A adds to a long collection of Chandra discoveries over the course of the telescope’s 20 years. In addition to finding the central neutron star, Chandra data have revealed the distribution of elements essential for life ejected by the explosion, clues about the details of how the star exploded, and much more.⁣ ⁣ Image credit: X-ray: NASA/CXC/RIKEN/T.

This rounded object isn't something seen through a microscope. Instead, it's a vast orb of gas in space, cast off by an aging star and seen by the @NASAHubble telescope. The star is visible in the orb's center, shining through the gases it formerly held onto for most of its stellar life. When stars like the Sun grow advanced in age, they expand and glow red. These so-called red giants then begin to lose their outer layers of material into space. More than half of such a star's mass can be shed in this manner, forming a shell of surrounding gas. At the same time, the star's core shrinks and grows hotter, emitting ultraviolet light that causes the expelled gases to glow. Image credit: ESA/Hubble & NASA, R.

As the @NASAHubble telescope turned its eye on Jupiter’s Great Red Spot, an Earth-sized storm rolling counterclockwise between two bands of clouds, it noticed something unusual. Can you tell what it is? 🤔⁣ ⁣ The color palette in the clouds is more intense than usual. The colorful bands, which flow in opposite directions at various latitudes, result from different atmospheric pressures. Lighter bands rise higher and have thicker clouds than the darker bands. The intensity of the colors reveals important clues about the planet’s turbulent atmosphere. ⁣ ⁣ Click the link in the bio for more info ⬆️⁣ ⁣ Credits: NASA, ESA, A.

It's the Baja California Peninsula in Northwestern Mexico, seen here in a stunning view she shared from her orbiting spot 250 miles above the Earth. Astronauts have used hand-held cameras to photograph the Earth for decades. Beginning with the Mercury missions in the early 1960s, astronauts have taken millions of photographs of our home planet. Today, they continue this tradition of Earth observation from the International Space Station ( @ISS ). Image credit: NASA #Earth #Home #Baja #California #BlueMarble #Views

When 2️⃣ become 1️⃣! This galactic duo of strange, luminescent creatures at play in this image are actually galaxies — realms of millions upon millions of stars. The galaxies are seen by our @NASAHubble telescope as their mutual gravitational attraction is pulling them closer and closer together and distorting their shapes in the process. Over time, the two galaxies will likely merge into one. Image credit: ESA/Hubble & NASA, A. Evans #Hubble #Galaxy #Merge #TwoBecomeOne

No, this red beam in space isn't a light saber! It's a galaxy, far, far away — 44 million light-years away, to be exact. We often imagine galaxies as having massive spiral arms or thick disks of dust, but not all galaxies are oriented face-on as viewed from Earth. From our viewpoint, our Spitzer Space Telescope can detect this galaxy's infrared light but can only view the entire galaxy on its side where we can't see its spiral features. We know it has a diameter of roughly 60,000 light-years — a little more than half the diameter of our own Milky Way galaxy.

Seven years. 13 miles. 22 samples. ⁣ ⁣ Our Curiosity rover has come a long way since touching down on Mars seven years ago. It has traveled a total of 13 miles (21 kilometers ) and ascended 1,207 feet (368 meters ) to its current location. Along the way, Curiosity discovered Mars had the conditions to support microbial life in the ancient past. And the rover is far from done, having just drilled its 22nd sample from the Martian surface. ⁣ ⁣ Curiosity captured this 360-degree panorama of a location on Mars called “Teal Ridge” on June 18, 2019.

A nearby galaxy contains a star-forming region where some 200 hot, young, massive stars reside. The cool dust and warmer gas in this stellar nursery appear as the wispy structures in an optical image from the @NASAHubble Space Telescope. In between these filaments are giant voids that are filled with hot, X-ray-emitting gas, seen by the @NASAChandraXRay Observatory. Chandra’s X-ray data (blue ) are combined in this image with optical data from Hubble (purple ). Astronomers think these bubbles are being blown off the surfaces of the young and massive stars throughout this star-forming region. Image credit: X-ray: NASA/CXC/CfA/R.

Moon chasing. 🌕 Usually, the crewmembers of the International Space Station ( @ISS ) see 16 moonsets and moonrises in a day. But every so often, the orbit of the station aligns with the day/night line on Earth, and the Moon and the Sun never appear to set. Here's a look at the Moon from our orbiting laboratory, as seen by @Astro_Christina Koch. As we prepare for future #Artemis missions, we are keeping the Moon in our sights.
