All that you change changes you. In a patch of the autumn sky that contains the constellations Perseus, Andromeda, and Triangulum, a beautiful interaction is happening. A larger spiral galaxy (UGC 1810) is pulled on by its smaller companion galaxy, distorting it into a rose-like shape. The uncommon spiral patterns in the larger galaxy are a telltale sign of interaction. The large, outer arm appears partially as a ring, a feature seen when interacting galaxies actually pass through one another. This suggests that the smaller companion dived deep, but off-center, through UGC 1810. UGC 1810 isn’t the only one changed, though. The smaller, S-shaped galaxy shows distinct signs of intense star formation at its nucleus, possibly triggered by the encounter with the larger galaxy. This image, released in 2011 to celebrate @NASAHubble ’s 21st launch anniversary, is a composite of Hubble Wide Field Camera 3 data taken on December 17, 2010, with three separate filters that allow a broad range of wavelengths covering the ultraviolet, blue, and red portions of the spectrum. Image description: The way these two galaxies are aligned make them look like a rose. A larger, spiral galaxy makes up the petals of the flower, while the smaller galaxy looks like the stem. Intensely bright and hot young blue stars bathe the very top of the image in blue light. In the background of the image are other galaxies and stars.

Ring ring! @NASAWebb calling 👋 This image of the Southern Ring Nebula was one of the very first that the James Webb Space Telescope shared with the world back in 2022. Officially known as NGC 3132, the Southern Ring Nebula is a cloud of gas and dust surrounding a dying star 2,500 light-years from Earth. With its high-resolution, infrared vision, Webb is able to peer through the dust to study the glimmering details within. Observations like these are helping astronomers understand the life and death of the stars that make up our galaxy—and Webb's just getting started. Image description: A planetary nebula, seen by the Webb telescope's NIRCam instrument, against the blackness of space, with points of starlight behind it. The nebula itself is shaped like an irregular oval, with lacy, reddish orange plumes of gas and dust. Further inside the circle, the gas and dust glows bright blue. A glowing white ring separates the red and blue gases. In the center of the rings are two stars, one glowing much brighter than the other, with diffraction spikes radiating out from it.

Oh, Neptune. Our Voyager 2 spacecraft captured this image of Neptune’s south pole as it sped away from the planet in 1989. Here’s one cool fact about Neptune’s south pole: it’s hotter than the rest of the planet by about 10 degrees Celsius (18 degrees Fahrenheit). Voyager 2 has been in operation since 1977 and is the only spacecraft to have ever visited Uranus and Neptune. During its travels through the outer solar system, Voyager 2 visited all four gas giant planets, and discovered and photographed many of the planets' moons. In November 2018, Voyager 2 reached interstellar space, the region between stars filled with material ejected by the death of nearby stars millions of years ago. Its twin spacecraft, Voyager 1, has resided in interstellar space since August 2012. Voyager 1 and 2 are now exploring where nothing from Earth has flown before. In their current mission, the Voyager Interstellar Mission, these two adventurers will explore the outermost edge of the Sun's domain. Image description: This image is mostly black. The southern pole of Neptune is all that’s visible. It curves along the bottom of the image, like a smile. From left to right along the curve, the planet is blue, fading into a pale yellow.

New whip, who this?⁣ ⁣ @Boeing ’s Starliner pulls into the orbital driveway of the International Space Station (@ISS ) carrying two @NASAAstronauts aboard, Butch Wilmore and Suni Williams. This is the spacecraft’s Crew Flight Test, which is testing the end-to-end capabilities of the spacecraft from liftoff to docking and the return to Earth.⁣ ⁣ After successfully launching on June 5 at 10:52 a.m. EDT (1452 UTC), the crew docked to the space station on June 6 at 1:34 p.m. EDT (1734 UTC). This was the first time humans have gone to space aboard a @ULAlaunch Atlas V rocket, and the first time astronauts launched on an Atlas-family class rocket since Gordon Cooper on the last Mercury program flight aboard Faith 7 in May 1963. It’s the same kind of rocket that launched the Curiosity and Perseverance rovers to Mars.⁣ ⁣ This is the first time in station history we’ve had three different spacecraft that carried crew to the orbiting lab docked at the same time. Even after more than 25 years of operation, we’re still experiencing so many exciting firsts. ⁣ ⁣ Stay tuned to nasa.gov/live over the next week for broadcast details on the many activities our astronauts will be up to on the orbital lab as they prepare for their return home.⁣ ⁣ Image description: Boeing’s Starliner spacecraft on NASA’s Crew Flight Test approaches the International Space Station while orbiting 263 miles above Quebec, Canada. The spacecraft contrasts with the blackness of space as it floats above the haze of Earth’s atmosphere.⁣ ⁣ Credits: NASA⁣ ⁣ #NASA #Boeing #Space #InternationalSpaceStation #ISS #Spacecraft #Starliner

Chilling out in Brazil 🌊 Located to the east of Rio de Janeiro, Cabo Frio is Portuguese for "Cape Cold" — so named because the ocean that surrounds it is unusually chilly. Strong northeasterly winds that blow along Cabo Frio's coast push warm surface waters away from the shore, allowing cool water from deeper in the ocean to rise to the surface. This upwelled water is also rich in nutrients, helping feed the rich marine ecosystem off of Cabo Frio's shores. This image of Cabo Frio was taken from space on September 16, 2023, by the OLI-2 (Operational Land Imager-2) instrument aboard Landsat 9, a partnership between NASA and @USGS . June 8 is #WorldOceansDay — follow @NASAEarth for more photos from around our home planet! Image description: A lush, green cape, as seen from space. The bottom and right borders are filled with deep blue water, but the land and various lagoons take up the rest of the image. Developed areas fill the bottom-right corner of the visible land, and stretch out across the beaches and lagoon shores beyond.

Can I ask you… your name? 🎀 Seen by @NASAHubble , this delicate red ribbon crossing the cosmos is a remnant of a supernova that was viewed by humans 1,000 years ago from 7,000 light-years away. The name of this stellar explosion is SN 1006, and was observed in 1006 A.D. It would have been the brightest star ever seen by humans—so bright that it could be seen during the daytime. A supernova is the explosive death of a white dwarf, the last stage of life of a Sun-like star. This twisted filament corresponds with where the blast is sweeping through surrounding gas. The diameter of this supernova is nearly 60 light-years, and is still expanding at a speed of about 6 million miles per hour (about 9.6 million kilometers per hour). Image description: A thin, red ribbon of gas crosses diagonally over the scene. Details in the trail show dimension and twisting of the stream of matter. In the background, black space is dotted with yellow stars and galaxies. Credit: NASA, ESA, Hubble Heritage Team (STScI/AURA) Acknowledgment: W.

Across the universe Euclid, a @europeanspaceagency telescope with NASA contributions, uncovered hidden regions of star formation in Messier 78 (the bright region in the center) for the first time and mapped gas and dust in exceptional detail. Using its infrared camera, the telescope looked through clouds that usually hide the smaller objects in this star nursery. This image and four others recently released showcase Euclid’s ability to explore two large-scale cosmic mysteries: dark matter and dark energy. While scientists have measured that dark matter makes up about 27% of the cosmos, they’re not sure what it is. Scientists think dark matter exists in a vast, web-like structure that winds through the whole universe – a gravitational scaffold that attracts most of the cosmos’ normal matter. They’ve determined that dark matter isn’t composed of known particles of matter because the universe would look quite different if it were. Observations of the universe have shown that the universe is expanding, and that it’s expanding faster now than it did in the past. We don’t know why, but the leading explanation is that the universe contains something that has a repulsive gravitational effect – it pushes the universe apart instead of pulling it back together. This phenomenon is called dark energy. By 2030, Euclid will create a cosmic map that covers almost a third of the sky. Scientists will then chart the presence of dark matter with higher precision than ever before. They also could use this map to study how dark energy’s strength has changed over time. Image description: Deep orange clouds of gas and dust swirl diagonally across the image. At center, bright stars give the region a purple hue. In the background is the black backdrop of space, dotted with bright stars and galaxies. Credit: ESA/Euclid/Euclid Consortium/NASA, image processing by J.-C. Cuillandre (CEA Paris-Saclay), G.

These are the voyages of the space shuttle Enterprise 🚀 On June 4, 1974—50 years ago today—construction began on NASA's first space shuttle. Officially designated OV-101, Enterprise received its more common name after a dedicated write-in campaign by fans of the original Star Trek TV series. When Enterprise made its public debut in California on Sept. 17, 1976, several cast members from the show, as well as creator Gene Roddenberry, were on hand to attend. Enterprise made its first independent flight on Aug. 12, 1977, released from atop a Boeing 747 to test the shuttle's approach and landing capabilities. Built to perform test flights in the atmosphere, Enterprise never reached orbit but paved the way for NASA's next generation of spacecraft. Space shuttle Columbia became the first shuttle to fly into space on April 12, 1981. Image description: Space shuttle Enterprise cruises high above hills and mountains, faintly visible at the bottom of the photo. The shuttle itself is pointing left and tilted slightly to its left, so the right wing is not visible. White with black trim, the craft has "United States" in large text on the side, with "Enterprise" and "NASA" in slightly smaller text elsewhere.

A nursery of stars, caught in NASA's Webb 🕸️ Officially known as 30 Doradus, this star-forming region is nicknamed the Tarantula Nebula for its long, intricate filaments of dust. It's the largest and brightest such region near our Milky Way galaxy—and it's home to some of the hottest, most massive stars we've ever observed. This image of the Tarantula Nebula was captured by the Near-Infrared Camera (NIRCam) aboard @NASAWebb . Webb's infrared instruments aren't just giving us a high-definition look into the universe—they're able to peer into clouds of gas and dust that are blocked to visual telescopes and our own eyes. Image description: A space image captured by the Webb telescope. Fluffy tan-colored nebula clouds, with rust-colored highlights, surround a black central area. Within that area, the focal point of the image is one large yellow star with eight long thin points. To the right of this star is a bright star cluster in an oval shape. The stars within the cluster look like tiny pale blue sparkles. The cluster is more densely packed at its core and scatters outward. Towards the bottom of the image, multiple arms appear to spiral out of a cloudy tan knob, resembling a spider or a squid structure. Other blue and yellow eight-pointed stars, as well as distant galaxies, are dotted throughout the image.

Setting the bar sky high 🌌⁣ ⁣ Witness the beauty of the barred spiral galaxy NGC 4731, captured by @NASAHubble . Located 43 million light-years away in the constellation Virgo, this stunning sight showcases billowing clouds of gas, bright pink star-forming regions, and a luminous central bar. Barred spiral galaxies, like this one, make up about 60% of all galaxies.⁣ ⁣ The bright bar in the center forms from stars and gas lining up in dense orbits. These bars help fuel star formation by moving matter and energy. The spiral arms of NGC 4731, influenced by nearby galaxies, stretch far beyond this close-up view.⁣ ⁣ Image description: A close-in view of a barred spiral galaxy. The bright, glowing bar crosses the center of the galaxy, with spiral arms curving away from the bar’s ends and continuing out of view. Bright patches of light where stars are forming surround the bar, which also holds dark lines of dust. The galaxy’s clouds of gas spread out from its arms and bar, giving way to a dark background with some foreground stars and small, distant galaxies.⁣ ⁣ Credit: ESA/Hubble & NASA, D.
