You live your life, you go in shadows 🎶⁣ ⁣ Our Moon is in its waning crescent phase, where most of the sunlight is illuminating its far side – the side we can’t directly see from Earth. The waning crescent is the last phase before the lunar cycle repeats with a “new moon” phase, where it is completely obscured from Earth’s perspective.⁣ ⁣ Image description: Seen from the @ISS , the Moon appears partially lit in the upper middle portion of the image. The Earth appears blue with faint white clouds in the atmosphere, stretching from the bottom left to the top right of the image. Black space surrounds the Moon.⁣ ⁣ Credit: NASA⁣ ⁣ #Moon #MoonPhase #ISS #NASA #Space

The trail we blaze⁣ ⁣ @NASAHubble catches a cosmic reef 163,000 light-years from Earth in the constellation Dorado. These nebulae are part of a vast star-forming region, the Large Magellanic Cloud, a satellite galaxy of the Milky Way full of massive stars.⁣ ⁣ The stars near the center of the image are around 10 to 20 times the size of our Sun, and their intense radiation heats surrounding dense gases like oxygen seen in light blue to 20,000°F (11,000°C). Hydrogen and nitrogen are relatively cooler in temperature and are seen in red. The nebula in the lower left was created from a star 200,000 times brighter than our Sun, which ejected gas in a series of eruptive events.⁣ ⁣ Image description: An image is split in two. In the bottom left of the first image a bright blue ring appears, slightly fading in all directions, with a small blue dot in the middle. Red and orange waves of gas ripple, arcing from top left to top right. A light blue center appears out of the sea of red, and several bright white dots shine through. In the top right, dark blue gas emanates from the blackness of space.⁣ ⁣ Credit: NASA, ESA, STScI⁣ ⁣ #Space #Nebula #Stars #CosmicReef #NASA #Hubble

It’s NICER in the witching hour 🧙‍♀️⁣ ⁣ This image of the whole sky shows 22 months of X-ray data recorded by NASA's Neutron star Interior Composition Explorer (NICER) payload aboard the International Space Station (@ISS ) during its nighttime slews between targets. ⁣ ⁣ NICER’s primary goals require that it target and track cosmic sources as the space station orbits the Earth every 93 minutes. But when the Sun sets and night falls on the orbital outpost, the NICER team keeps its detectors active while the instrument goes from one target to another, which can occur eight times each orbit. ⁣ ⁣ Each arc traces X-rays, as well as occasional strikes from energetic particles, captured during these night moves. The brightness of each point in the image is a result of these contributions as well as the time NICER has spent looking in that direction. A diffuse glow permeates the X-ray sky even far from bright sources.⁣ ⁣ Image description: On a black background are a network of orange filaments connecting a number of bright spots. The bright spots indicate places where the filaments cross, and are sources in the sky where NICER often points its telescope. The swirling loops between those points reveal the path NICER’s telescope takes between these sources. The image is watermarked “Credit: NASA/NICER.”⁣ ⁣ Credits: NASA/NICER⁣ ⁣ #NASA #Space #ISS #InternationalSpaceStation #NICER #NightSky #Night #Xray

Two views of a cosmic classic @NASAHubble captured this iconic view of the Pillars of Creation, showing off towers that stretch light-years in length, around 7,000 light-years away from Earth in the direction of the constellation Serpens. The Pillars of Creation are part of an active star-forming region within the Eagle Nebula, hiding newborn stars in the columns of dust and gas. In this image captured in visible light, blue represents oxygen, red sulfur, and green is both nitrogen and hydrogen. @NASAWebb also captured the Pillars of Creation in near-infrared-light, helping researchers revamp their ideas on how new stars form in nebulae. By viewing the cosmic phenomena in different wavelengths, scientists can get a more precise count of stars hidden within and beneath the pillars. Image descriptions: Two images are shown of the Pillars of Creation, a star-forming region in space. The first one is Hubble’s visible-light view, which shows darker pillars that rise from the bottom to the top of the screen, ending in three points. The background is opaque, set off in yellow and green toward the bottom and blue and purple at the top. A handful of stars of various sizes appear. Webb’s near-infrared image shows the same pillars, but they are semi-opaque and rusty-red-colored. The peaks of the second and third pillars are set off in darker shades of brown and have red outlines. The background is cast in darker blues and blacks, and stars in yellow and white of all sizes speckle the entire scene. Webb’s image was cropped and rotated to match Hubble’s view, so much of the top right corner and a small portion of the left corner has been left black.

This is what it looks like when the Sun lights up the night sky. Earlier this month, the Sun created the largest solar storm to reach Earth in two decades, with possibly the most brilliant and widespread display of auroras in the past 500 years. The storm’s coronal mass ejections soared through space at speeds up to 3 million mph (4.8 million kph), bunching up in waves that reached Earth on May 10 and creating a G5 geomagnetic storm — a level last seen on Earth in 2003. As the storm reached Earth, it created a beautiful aurora that illuminated the sky and was seen around the globe, even visible in areas including the southern U.S. and northern India. Monitoring data on space weather help us understand the impacts on satellites, crewed missions, Earth, and space-based infrastructure. Submitting your aurora photos and reports to the NASA-funded Aurorasaurus.org site can help scientists study the event as we work to understand and prepare for these events. Image description: An image of a coronal aurora taken from the point of view of somebody standing on the ground and looking directly upward at the sky. Dark trees frame the sky, stretching up toward the jagged streaks of electric green and watermelon pink. The vibrant lights obscure the night sky, dotted with faint stars.

The Sun is always rising somewhere.⁣ ⁣ No matter how dark or long the night feels, the Earth keeps spinning and your sunrise is right around the corner.⁣ ⁣ Taken on May 15 from the International Space Station, this image highlights the dramatic lighting following an orbital sunrise, illuminating clouds over the Atlantic Ocean. At the speed it travels, the @ISS goes around the world in 90 minutes. That means crew members on the station see 16 sunrises and sunsets each day.⁣ ⁣ Image description: A swipethrough image of white cloud tops over the Atlantic Ocean glowing from the light of a recent orbital sunrise. The sunlight’s angle casts a dramatic shadow over the fluffy clouds, revealing the fine contours and textures of the cottony layer. The hazy, blue edge of Earth’s atmosphere outlines the scene, mingling with the blackness of space in the background.⁣ ⁣ Credit: NASA⁣ ⁣ #NASA #Earth #ISS #SpaceStation #Sunrise #Clouds #Astrophotography⁣

A star is born ✨⁣ ⁣ HP Tau, 550 light-years from Earth, is the youngest star in a three-star system. (It’s the one at the top of the triangle.) HP Tau is in the process of turning into a star like our Sun, but it’s likely less than 10 million years old—for comparison, the Sun is around 4.6 billion years old.⁣ ⁣ Scientists are using our orbiting @NASAHubble telescope to study HP Tau and learn more about protoplanetary disks, the disks of material around stars that form into planets over millions of years. HP Tau is also a variable star, which means that it gets brighter and dimmer over time. These variations could be due to the star’s turbulent childhood, with gas and dust around the star both blocking its light and feeding its growth. More predictable changes in brightness could be caused by giant sunspots rotating in and out of view.⁣ ⁣ Image description: A hazy blue nebula surrounds a cluster of bright stars. Three of these stars form a triangle, with the topmost one (HP Tau) appearing to be wrapped within the nebula from our perspective. A number of dimmer, pinpoint-like stars and galaxies fill the background.⁣ ⁣ Credit: NASA, ESA, G.

Tuesday? More like…bluesday. Our Juno spacecraft captured this view of Jupiter’s blue southern pole on Dec. 11, 2016. This image was taken from an altitude of about 32,400 miles (52,200 kilometers) above the planet’s cloud tops. The equatorial region of Jupiter appears as neat belts of stormy turbulence. Toward its poles, however, the organized chaos devolves into a mix of clouds and air streams. Juno left Earth to study Jupiter back in 2011, arriving at the gas giant in 2016. Ever since, it has been observing the planet and its many moons, learning about the planet, our solar system, and gas giants across the universe. Image description: A swipethrough of Jupiter’s south pole framed by black space. It appears as a semicircle of spots and swirling, filamentous clouds. They are a rich, deep blue in the center, bleeding into orange and then tan around its rim.

Aurora Borealis!? At this time of year, at this time of day, in this part of the country!? 💛 This weekend, skywatchers across the Northern Hemisphere reported seeing auroras as far south as the Bahamas. Known as aurora borealis—or northern lights—in the northern hemisphere and aurora australis—or southern lights—in the southern hemisphere, these cosmic phenomena are caused by the Sun. Our Sun is an active participant in the solar system, influencing planets with its turbulent surfaces that experience storms, eruptions, and sunspots. Coronal Mass Ejections—a type of solar eruption—are giant clouds of magnetized solar particles blasted into space, which, when directed at Earth, can produce geomagnetic disturbances like auroras. Image description: his image was taken on May 11, 2024 near Malad City, Idaho. A tree (bottom right) and its branches are silhouetted against the dramatic night sky, which is red, purple and green thanks to the aurora. Streaks of light shimmer, making the aurora look like the folds in a curtain (middle left). A road winds toward the mountainous horizon (bottom middle), and the back of a car appears (bottom right)—the @iss streaks in white (middle top) across the sky, which is dotted with white stars.

Ready to plunge into a black hole?⁣ ⁣ NASA supercomputers produced this immersive visualization that allows you to dive in without it becoming a one-way trip. The destination: a black hole, similar in size to the one at the heart of the Milky Way.⁣ ⁣ As you get closer to the black hole, your speed climbs until it approaches the speed of light — the cosmic speed limit! The glow from the stars in the background and from the disk of hot material surrounding the black hole becomes amplified, growing brighter and whiter. The effect is similar to how the sound of an oncoming racecar rises in pitch.⁣ ⁣ Along the way, the black hole’s disk and the night sky become increasingly distorted and even form multiple images as their light crosses the increasingly-warped space-time.⁣ ⁣ This 400-million-mile (640-million-km) trip would take you about 3 hours. It’s quite a ride — and you’d only get to do it once if this wasn’t a simulation!⁣ ⁣ If you’d like more content like this, be sure to follow our new @NASAUniverse account.⁣ ⁣ Credit: NASA’s Goddard Space Flight Center/J. Schnittman and B. Powell⁣ ⁣ Music: “Tidal Force,” Thomas Daniel Bellingham [PRS], Universal Production Music⁣ ⁣ Video description:⁣ A black hole with a glowing orange disk of material sits near the center of a starry background. Light from the disk is distorted by the black hole’s strong gravity, with the far side of the disk visible above and below it. The camera approaches the black hole, making almost two trips around before crossing the event horizon. As the camera loops around, the screen is black toward the black hole’s location at the bottom. The orange disk appears to stretch and arc into a thin line that breaks off into a loop that passes overhead several times. Once inside the event horizon, the screen becomes increasingly black. The orange disk makes one more loop before becoming a thin ribbon across the top. The starry sky crams together just above the ribbon. Finally, the camera shakes, indicating its destruction.⁣ ⁣ #BlackHoleWeek #Warped #BlackHoles #Gravity #Space #NASA
