This object was featured in a previous Hubble photo release, but now new processing techniques have been applied, bringing out fine details of the nebula’s delicate threads and filaments of ionised gas. To create this colorful image, observations taken by Hubble's Wide Field Camera 3 instrument through 5 different filters were used. The new post-processing methods have further enhanced details of emissions from doubly ionized oxygen (seen here in blues), ionized hydrogen and ionized nitrogen (seen here in reds).
The Veil Nebula lies around 2,100 light-years from Earth in the constellation of Cygnus (The Swan), making it a relatively close neighbour in astronomical terms. Only a small portion of the nebula was captured in this image.
The Veil Nebula is the visible portion of the nearby Cygnus Loop, a supernova remnant formed roughly 10,000 years ago by the death of a massive star. The Veil Nebula’s progenitor star—which was 20 times the mass of the Sun—lived fast and died young, ending its life in a cataclysmic release of energy. Despite this stellar violence, the shockwaves and debris from the supernova sculpted the Veil Nebula’s delicate tracery of ionized gas—creating a scene of surprising astronomical beauty.

Tour: An Expanse of Light | NASA's Chandra X-ray Observatory
The recent launches of the James Webb Space Telescope and the Imaging X-ray Polarimetry Explorer, or "IXPE," by NASA and its international partners are excellent reminders that the universe emits light or energy in many different forms. To fully investigate cosmic objects and phenomena, scientists need telescopes that can detect light across what is known as the electromagnetic spectrum.
This gallery provides examples of the ways that different types of light from telescopes on the ground and in space can be combined. The common thread in each of these selections is data from NASA's Chandra X-ray Observatory, illustrating how X-rays—which are emitted by very hot and energetic processes—are found throughout the universe.
The collection contains objects ranging from a supernova remnant within our Galaxy to an enormous galaxy cluster millions of light years away. Each image contains X-rays from Chandra in combination with data from other telescopes that capture different types of light. The objects are the binary system R Aquarii, the supernova remnant Cassiopeia A, the "Guitar Nebula" and its pulsar, the galaxy cluster Abell 2597, and the NGC 4490 galaxy.
In the coming weeks and months, we will hear much more about JWST and IXPE. It will be exciting to see what discoveries they make when their data are joined those other telescopes, including Chandra, in exploring our Universe.

The Lagoon Nebula: "A 370-million-pixel Starscape" | ESO
The third image of ESO’s GigaGalaxy Zoom project is an amazing vista of the Lagoon Nebula taken with the 67-million-pixel Wide Field Imager attached to the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile. The image covers more than one and a half square degree—an area eight times larger than that of the Full Moon—with a total of about 370 million pixels. It is based on images acquired using three different broadband filters (B, V, R) and one narrow-band filter (H-alpha).
Webb Sneak Preview: The Lagoon Nebula (Infrared View) | Hubble
This star-filled image, taken by NASA’s Hubble Space Telescope in near-infrared wavelengths of light, reveals a very different view of the Lagoon Nebula compared to its visible-light portrait. Making infrared observations of the cosmos allows astronomers to penetrate vast clouds of gas and dust to uncover hidden gems. Hubble’s view offers a sneak peek at the dramatic vistas NASA’s James Webb Space Telescope will provide.
The most obvious difference between Hubble’s infrared and visible photos of this region is the abundance of stars that fill the infrared field of view. Most of them are more distant, background stars located behind the nebula itself. However, some of these pinpricks of light are young stars within the Lagoon Nebula. The brilliant star near the center of the frame, known as Herschel 36, is about 200,000 times brighter than our Sun.
This hefty star is 32 times more massive and eight times hotter than our Sun. Its powerful ultraviolet radiation and fierce stellar winds are carving away the surrounding nebula, removing the raw materials that smaller stars need to form. Dark smudges known as Bok globules mark the thickest parts of the nebula, where dust protects still-forming stars and their planets. While Hubble cannot penetrate these dusty clumps, Webb will be able to see through them.
Webb will probe young stars still in the process of forming. It also will examine the disks of dust and gas surrounding those stars, known as protoplanetary disks, in order to determine how far the planet formation process has proceeded. Webb will determine whether the inner regions of those disks have been cleared out, the dust either swept up by protoplanets or swept away by stellar winds.
Webb could take a stellar census of the Lagoon Nebula to determine not only how many massive stars it contains, but also how many Sun-like stars and how many failed stars known as brown dwarfs. This would enable astronomers to get the big picture of the stellar population across the entire range of masses, particularly at the low end.
The image shows a region of the nebula measuring about 4 light-years across. The observations were taken by Hubble’s Wide Field Camera 3 between Feb. 12 and Feb. 18, 2018.

Gas and dust condense, beginning the process of creating new stars in this image of Messier 8, also known as the Lagoon Nebula. Located four to five thousand light-years away, in the constellation of Sagittarius (the Archer), the nebula is a giant interstellar cloud, one hundred light-years across. It boasts many large, hot stars, whose ultraviolet radiation sculpts the gas and dust into unusual shapes. Two of these giant stars illuminate the brightest part of the nebula, known as the Hourglass Nebula, a spiralling, funnel-like shape near its center. Messier 8 is one of the few star-forming nebulae visible to the unaided eye, and was discovered as long ago as 1747, although the full range of colors was not visible until the advent of more powerful telescopes. The Lagoon Nebula derives its name from the wide lagoon-shaped dark lane located in the middle of the nebula that divides it into two glowing sections.
This image combines observations performed through three different filters (B, V, R) with the 1.5-meter Danish telescope at the ESO La Silla Observatory in Chile.

This Hubble Space Telescope (HST) image reveals a pair of one-half light-year long interstellar 'twisters'—eerie funnels and twisted-rope structures—in the heart of the Lagoon Nebula, also known as Messier 8, which lies 5,000 light-years away in the direction of the constellation Sagittarius.
This close-up shot of the center of the Lagoon Nebula (Messier 8) clearly shows the delicate structures formed when the powerful radiation of young stars interacts with the hydrogen cloud they formed from. Distance: 5,000 light years
This image was created from exposures taken with the Wide Field Channel of the Advanced Camera for Surveys on Hubble. Light from glowing hydrogen (through the F658N filter) is colored red. Light from ionized nitrogen (through the F660N filter) is colored green and light through a yellow filter (F550M) is colored blue. The exposure times through each filter are 1560 s, 1600 s and 400 s respectively. The blue-white flare at the upper-left of the image is scattered light from a bright star just outside the field of view. The field of view is about 3.3 by 1.7 arcminutes.
European Astronaut Samantha Cristoforetti: EVA Prep | International Space Station
Can you sense Samantha's excitement just before her first spacewalk outside the International Space Station? She can be seen here putting on a Russian Orlan spacesuit. Expedition 67 Commander Oleg Artemyev of Roscosmos and Flight Engineer Samantha Cristoforetti (Italy) of the European Space Agency (ESA) concluded their spacewalk or extravehicular activity (EVA) at 5:55 p.m. EDT, July 21, 2022, after 7 hours and 5 minutes.
Artemyev and Cristoforetti completed all but one of their major objectives, which included the deployment of 10 nanosatellites designed to collect radio electronics data during the spacewalk and installing platforms and workstation adapter hardware near the 37-foot-long manipulator system mounted to Nauka. The spacewalkers also relocated the arm’s external control panel and replaced a protective window on the arm’s camera unit. The last planned activity, to extend a Strela telescoping boom from Zarya to Poisk, will be completed on a future spacewalk.
Additional spacewalks are planned to continue outfitting the European robotic arm and to activate Nauka’s airlock for future spacewalks. The work on the European robotic arm will be used to move spacewalkers and payloads around the Russian segment of the station.
This was the sixth spacewalk in Artemyev’s career, and the first for Cristoforetti. It was the sixth spacewalk at the station in 2022 and the 251st spacewalk for space station assembly, maintenance, and upgrades.

The Lagoon Nebula: Visible & Infrared Light View | Hubble
This short videoclip shows the Lagoon Nebula, which was observed to celebrate Hubble's 28th anniversary in space in 2018, first in the visible light and then in the infrared. Both observations were made by Hubble.
While the observations in visible light allow astronomers to study the gas in full detail, the infrared light cuts through the obscuring patches of dust and gas, revealing the more intricate structures underneath and the young stars hiding within it. Only by combining optical and infrared data can astronomers paint a complete picture of the ongoing processes in the nebula.

This image of the Lagoon Nebula, captured by the NASA/European Space Agency Hubble Space Telescope to celebrate its 28th year in space back in 2018, shows colorful clouds of gas and dust of this star-formation region in incredible detail.
The image reveals a fantastic landscape of ridges, cavities, and mountains of gas and dust. This dust-and-gas landscape is being sculpted by powerful ultraviolet radiation and hurricane-like stellar winds unleashed by a young star. Located at the center of the image, the star, known as Herschel 36, is about 200,000 times brighter than our Sun.
This video begins with a ground-based view of the night sky, before zooming in on the Lagoon Nebula as it can be seen with the NASA/ESA Hubble Space Telescope. The nebula is immense—55 light-years wide and 20 light-years tall—and so Hubble can only image a tiny part of it in stunning detail.
This nebula is filled with intense winds from hot stars, churning funnels of gas, and energetic star formation, all embedded within an intricate haze of gas and pitch-dark dust.
To celebrate its 28th anniversary in space back in 2018, the NASA/European Space Agency Hubble Space Telescope took this amazing and colorful image of the Lagoon Nebula. The whole nebula, about 4,000 light-years away, is an incredible 55 light-years wide and 20 light-years tall. This image shows only a small part of this turbulent star-formation region, about four light-years across. The Lagoon Nebula is classified as an emission nebula in the H II region.
This stunning nebula was first catalogued in 1654 by the Italian astronomer Giovanni Battista Hodierna, who sought to record nebulous objects in the night sky so they would not be mistaken for comets. Since Hodierna’s observations, the Lagoon Nebula has been photographed and analysed by many telescopes and astronomers all over the world.
The observations were taken by Hubble’s Wide Field Camera 3 between February 12-18, 2018.
