Cosmic bubbles in the Milky Way! 🌌 ⁣
⁣
This Spitzer Space Telescope image shows a cloud of dust and gas filled with bubbles 10 to 30 light-years across, each containing hundreds of thousands of stars. ⁣
⁣
This active region of star formation is located within the Milky Way galaxy, in the constellation Aquila (also known as the Eagle). Black veins running throughout the cloud are regions of especially dense cold dust and gas where even more new stars are likely to form.⁣
⁣
The colors in this image represent different wavelengths of infrared light. Blue represents a wavelength of light primarily emitted by stars; dust and organic molecules called hydrocarbons appear green, and warm dust that's been heated by stars appears red.⁣

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.⁣

In this large celestial mosaic, our Spitzer Space Telescope captured a stellar family portrait! 👨‍👩‍👧‍👦 You can find infants, parents and grandparents of star-forming regions all in this generational photo. Swipe left to uncover some of its members! ⁣
⁣
There’s a lot to see in this image, including multiple clusters of stars born from the same dense clumps of gas and dust – some older and more evolved than others. Dive deeper into its intricacies by visiting https://go.nasa.gov/2XpiWLf ⁣

When you wish upon a star… Hubble captures it from afar ✨This week our @NASAHubble Space Telescope celebrated 29 years of dazzling discoveries, serving as a window to the wonders of worlds light-years away. ⁣
⁣
Hubble continues to observe the universe in near-ultraviolet, visible, and near-infrared light. Over the past 29 years, it has captured the farthest views ever taken of the evolving universe, found planet-forming disks around nearby stars and identified the 1st supermassive black hole in the heart of a neighboring galaxy. ⁣
⁣
Enjoy some of Hubble’s highlights  over the years! Learn what each image is in the comments. ⁣

We're celebrating 29 years since the launch of the @NASAHubble Space Telescope with a new look at the Southern Crab Nebula! See the nebula's hourglass structure ⏳, with bright edges like crab legs 🦀 ? The nebula is located several thousand light-years from Earth and appears to have two nested hourglass-shaped structures that were sculpted by a whirling pair of stars in a binary system. The duo consists of an aging red giant star and a burned-out star, a white dwarf. The red giant is shedding its outer layers. Some of this ejected material is attracted by the gravity of the companion white dwarf. The result is that both stars are embedded in a flat disk of gas stretching between them. This belt of material constricts the outflow of gas so that it only speeds away above and below the disk, forming what looks like an hourglass-shaped nebula.

3 million light-years from Earth, and half the size of our galaxy, this enormous star-forming nebula is one of the Triangulum galaxy’s spiral arms containing more than 200 young stars.

Under exceptionally clear and dark skies, the Triangulum galaxy is one of the most distant objects that a keen-eyed observer can view with the unaided eye.

It is seen here by the @NASAHubble telescope in a composite image from 1994, 1995, and 2001 observations. A different Hubble, astronomer Edwin Hubble, previously studied the Triangulum galaxy, which helped him to estimate the object’s distance and prove that it rests within a separate galaxy outside our own.

How do you photograph a galaxy that stretches for thousands of light-years? One @NASAHubble Space Telescope image at a time.

This portrait of the Triangulum galaxy was stitched together from 54 Hubble images and spans an area 14,500 light-years across — making it the largest high-resolution image of Triangulum ever assembled.

Triangulum is the junior member of a trio of spiral galaxies, which includes ours (the Milky Way) and Andromeda. Compared to other recorded galaxies, Triangulum has a very neat and tidy spiral. The dust is evenly distributed throughout. Astronomers suspect that Triangulum’s tidiness is a result of having successfully avoided disruptive interactions with other galaxies. 
How many stars are burning in this capture of Triangulum? Nearly 25 million. Striking areas of star birth glow bright blue throughout the galaxy, particularly in beautiful nebulas of hot ionized hydrogen gas. 
Astronomers have only just begun to mine the enormous amount of data generated by these new Hubble observations, which will yield important insights into the process of star formation.

Starry night🌟4,000 light years from Earth, the Lagoon Nebula is seen with its swirling clouds of gas and dust in a pattern reminiscent of Van Gogh. This nebula provides astronomers an excellent opportunity to study the properties of very young stars. Many infant stars give off copious amounts of high-energy light including X-rays, which are seen in the Chandra X-ray data (in pink) to reveal the infant stars budding in the surreal nightscape. The X-ray data have been combined with an optical image of Messier 8 from the Mt. Lemmon Sky Center in Arizona.

A celestial holiday wreath made of sparkling lights! Swaddled in a gossamer cocoon of reflective dust and illuminated, the super star in the center of this image from the @NASAHubble Space Telescope is ten times more massive than the Sun and 200 times larger. The super star is also one of the most luminous with an average intrinsic brightness is 15,000 times greater than the Sun's luminosity.

This star also rhythmically brightens and dims over a six-week cycle. The nebula flickers in brightness as pulses of light from the star propagate outwards. Hubble took a series of photos of light flashes rippling across the nebula in a phenomenon known as a "light echo." Even though light travels through space fast enough to span the gap between Earth and the Moon in a little over a second, the nebula is so large that reflected light can actually be photographed traversing the nebula.

By observing the fluctuation of light itself, as well as recording the faint reflections of light pulses moving across the nebula, astronomers are able to measure these light echoes and pin down a very accurate distance. The distance to the super star has been narrowed down to 6,500 light-years (with a margin of error of only one percent).

Not all stars are the same. @NASAHubble's Wide Field Camera 3 captured this star cluster, called NGC 1866, found at the very edges of the Large Magellanic Cloud, a small galaxy located near the Milky Way. Star clusters are common structures throughout the universe, each made up of hundreds of thousands of stars all bound together by gravity. The cluster was discovered in 1826 by Scottish astronomer James Dunlop, who cataloged thousands of stars and deep-sky objects.

Is that a witch screaming out into space?! This infrared portrait shows the Witch Head nebula, named after its resemblance to the profile of a wicked witch. Spotted by our Wide-Field Infrared Survey Explorer, the Witch Head nebula is estimated to be hundreds of light-years away in the Orion constellation. Astronomers say the billowy clouds of the nebula, where baby stars are brewing, are being lit up by massive stars. Dust in the cloud is being hit with starlight, causing it to glow with infrared light that was picked up by our detectors.
