An au-royal view! @NASAWebb captured bright auroras on Neptune, confirming their presence on the planet. This image of Neptune combines @NASAHubble’s image of Neptune from the telescope’s Wide Field Camera 3 with Webb’s Near-Infared Spectograph, showing auroral activity in cyan splotches alongside white clouds. Auroras occur when energetic particles, often originating from the Sun, become trapped in a planet’s magnetic field and eventually strike the upper atmosphere. The energy released during these collisions creates the signature glow. All of the other gas giants in our solar system have aurora too. Neptune’s auroras was the last to be confirmed with imagery, although NASA’s Voyager 2 flyby detected hints of their presence in 1989.

It is a multi-hued blue orb. There are white smudges at 7 o’clock and just above 5 o’clock, and also at the center of the planet and at the top. There are cyan smudges vertically along the right side, with the top of the smudging more translucent than the bottom. Image 2: Neptune, as seen from the Hubble Space Telescope. It is a blue circle, tilted about 25 degrees to the left. There are white smudges at 7 o’clock and just above 5 o’clock.

Thirty-five never looked better! Take a tour through Hubble's 35th anniversary images, narrated by senior project scientist Dr. Jennifer Wiseman. Explore more at the link in our bio! #Hubble35 #NASA #Hubble #space #science #astronomy #universe #cosmos #telescope #STEM
About 160,000 light-years away, the star cluster NGC 1850 shines in this image from Hubble's 33rd year. Like most globular clusters, NGC 1850 is a spherical collection of densely packed stars held together by mutual gravitational attraction. Unlike most globular clusters, however, the stars of NGC 1850 are relatively young. Globular clusters with young stars such as NGC 1850 are not present in our own Milky Way galaxy, and NGC 1850 resides within a satellite galaxy to ours, called the Large Magellanic Cloud. NGC 1850 is approximately 100 million years old. We're sharing one outstanding image from each year of Hubble’s mission to celebrate its upcoming 35th birthday – counting down to a new series of anniversary images! Stay tuned for more, and get caught up at the link in our bio. Image description: A yellow star cluster glitters near the top center of the image.

A light show on Uranus🪐 An international team of astronomers used over 10 years of Hubble observations to refine the planet’s rotation period at an accuracy 1,000 times greater than before, using the ultraviolet light emitted by its aurorae. Uranus’ aurorae, unlike those of other planets in our solar system, behave unpredictably due to its highly tilted magnetic field, which is not aligned with its rotational axis. These findings will help astronomers understand Uranus’ magnetic field and provide vital information for future missions. Find out more at the link in our bio! Image description: These three images each show Uranus and dynamic aurora activity. The images were captured in October 2022 on the 8th, 10, and 24th respectively. Each image shows a centred planet with a strong blue hue and a visible white region. A faint ring is also visible around the planet in each image. Each image shows fuzzy blue/purple regions hovering over the planet in different locations to indicate the aurorae. Image Credit: ESA/Hubble, NASA, L. Lamy, L.

Celestial fireworks 🎇 This sparkling image, released in Hubble's 21st year, shows a young cluster of stars surrounded by interstellar gas and dust. Called NGC 3603, this star cluster is about 20,000 light-years away. Most of the stars in the cluster were born around the same time, but their difference in mass means they are at different life stages. We're sharing one outstanding image from each year of Hubble’s mission to celebrate its upcoming 35th birthday – counting down to a new series of anniversary images! Stay tuned for more, and get caught up at the link in our bio! Image description: A densely packed cluster of yellow stars shines at the center of the image, with more stars scattered throughout. Clouds of glowing indigo gas and dust dominate the lower half of the view, and a red star with diffraction spikes shines at upper right. Image credit: NASA, ESA, R.

Shine bright like NGC 6397! ✨ This star cluster glitters with the light from hundreds of thousands of stars. At 7,800 light-years away, this is one of the closest globular clusters to Earth. Globular clusters are roughly spherical collections of stars bound together by their mutual gravity. The cluster's blue stars are near the end of their lives. These stars have used up their hydrogen fuel that makes them shine. Now, they're converting helium to energy in their cores, which fuses at a higher temperature – resulting in a blue color, as seen in this Hubble view from the mission's 18th year.

To celebrate Hubble’s 35th anniversary, ESA is sharing a new image series that updates previously released Hubble targets with the latest Hubble data. This new image of the dazzling young star cluster NGC 346 is the first to combine Hubble observations made at infrared, optical, and ultraviolet wavelengths, creating an intricately detailed view of this vibrant star-forming factory. NGC 346 is home to more than 2,500 newborn stars, the most massive of which blaze with an intense blue light in this image. The glowing pink nebula and snakelike dark clouds are remnants of the birthplace of stars in the cluster. NGC 346 is located in the Small Magellanic Cloud, a satellite galaxy of the Milky Way that lies 200,000 light-years away in the constellation Tucana. Find out more about this image at the link in our bio! Image description: A star cluster within a nebula. Thin, pale-blue wisps of clouds fill the background while denser areas of pinkish clouds appear superimposed upon them. The star cluster holds bright-blue stars that illuminate the nebula. Large arcs of dense, reddish-brown dust pressed together by the stars’ radiation, curve around, in front of, and behind the clustered stars. Many orange stars are visible in the background behind the clouds of the nebula. Image credit: ESA/Hubble & NASA, A. Nota, P. Massey, E. Sabbi, C. Murray, M.

This brilliant image of stars, glowing gas, and interstellar dust shows the barred spiral galaxy NGC 1300. Released in 2005, this image is so big that two adjacent pointings of Hubble were necessary to capture the whole thing. Barred spirals differ from normal spiral galaxies in that the arms of the galaxy do not curve all the way into the core, but are connected to the two ends of a straight bar of stars containing the nucleus at its center.

These Hubble images are gorgeous to look at... but what if you could listen to them, too? There's a whole new way to analyze data from Hubble images. With "Hearing Hubble," you can create your own sonifications. Make a cosmic symphony by deciding what information to map to musical settings, like instruments and tones. You can sonify these images (and more!) at the link in our bio. Image descriptions/credits: 1 - Messier 4. A huge cluster of stars shines against black space, more closely concentrated at center. The stars have diffraction spikes and shine in shades of blue, white, and orange. (ESA/Hubble & NASA) 2 - Monkey Head Nebula. Massive clouds of brown, gray, and blue dust fill the image, coalescing into giant, sideways pillars and peaks. Several bright stars shine throughout. (NASA, ESA, and the Hubble Heritage Team (STScI/AURA)) 3 - NGC 4535. A massive spiral galaxy fills the image, with a bright yellow core surrounded by winding arms laced with dark brown dust and blue stars. A few foreground stars shine throughout.

Bright blue clusters of star formation and red clumps of hydrogen shine among dark lanes of dust in this new Hubble image of the galaxy NGC 4536. Located about 50 million light-years away, NGC 4536 is what’s known as a “starburst” galaxy – meaning that it forms stars at a tremendous rate that uses up the gas in the galaxy relatively quickly. This is part of a series of new images from archival Hubble data. Find out more about these new cosmic views at the link in our bio as we get ready for the mission’s 35th anniversary next month!

Pink clumps of ionized hydrogen and blue clusters of stars, along with dark dust lanes, are visible in the arms. #NASA #Hubble #galaxy #space #science #stars #astronomy #universe #cosmos #telescope
