Image Highlights of Hubble Space Telescope's 36th Anniversary Year (1990-2026)

Image Highlights of Hubble Space Telescope's 36th Anniversary Year (1990-2026)

These are examples of a variety of images that have been featured throughout Hubble's 36th year of operations. Among these were the star-forming region N11 in the Large Magellanic Cloud, the shells of stardust that make up the Egg Nebula, the Cat’s Eye Nebula together with ESA’s Euclid, and a brand-new image of the famous Crab Nebula. Hubble also showcased the smouldering heart of M82, swirling spiral galaxies UGC 11397 and Arp 4, dust rings around galaxy NGC 7722, the glittering stars of globular cluster NGC 1786, and the immense galaxy cluster Abell 209.

The Hubble Space Telescope has taken over 1.7 million observations to date. Almost 29,000 astronomers have published peer-reviewed science papers using Hubble data collected over the telescope’s 36-year lifetime, resulting in more than 23,000 publications, with almost 1100 in 2025 alone. Since 2022, researchers have regularly combined Hubble’s observations with those from the James Webb Space Telescope to push opportunities for discovery further.

The Hubble Space Telescope is a project of international cooperation between the European Space Agency (ESA) and NASA.

Five Things You Didn't Know About NASA Astronaut Christina Koch Pre-Artemis II

Five Things You Didn't Know About NASA Astronaut Christina Koch Pre-Artemis II


Engineering and physics degrees? Check. 
Previous work for NASA? Another check. Experience working at the South Pole and America Samoa? Of course. However, the “usual credentials” do not fully reflect the background of astronaut Christina Koch. Check out her favorite extreme adventures, her dabbling with lightning, and a foreign trip that changed her perspectives on life before her historic journey to the Moon on the Artemis II Mission this year.

NASA astronaut candidate Christina Koch (maiden name Hammock) in 2013: "I really strongly believe in both the practical aspects of the research being conducted as well as the larger picture of the human spaceflight program bringing us forward as a human race and uniting us in exploring the universe." 

In 2012, Christina joined the United States National Oceanic and Atmospheric Administration (NOAA), first as a field engineer at the Global Monitoring Division Baseline Observatory in Barrow, Alaska (now Utqiaġvik), and then as station chief of the American Samoa Observatory. 

Christina Hammock Koch [pronounced “Cook”] was later selected as a NASA astronaut candidate in 2013. Prior to her historic Artemis II Moon Mission, she served as flight engineer on the International Space Station (ISS) for Expeditions 59, 60 and 61. Koch set a record for the longest single spaceflight by a woman with a total of 328 days in space and participated in the first all-female spacewalk.

Wide-field view: Elliptical Galaxy Messier 105 in Leo | Hubble Space Telescope

Wide-field view: Elliptical Galaxy Messier 105 in Leo | Hubble Space Telescope

M105 is an elliptical galaxy 32 million light-years away in the constellation Leo. It is the largest elliptical in the Messier catalog that is not a member of the Virgo cluster of galaxies. M105 does, however, belong to the M96 (or Leo I) Group. This includes neighbors M95 and M96 as well as several other fainter galaxies. M105 is the brightest elliptical galaxy within the Leo I galaxy group. 

It might appear featureless and unexciting at first glance, but NASA/European Space Agency Hubble Space Telescope observations of this elliptical galaxy—known as Messier 105—show that the stars near the galaxy’s center are moving very rapidly. Astronomers have concluded that these stars are zooming around a supermassive black hole with an estimated mass of 200 million Suns. This black hole releases huge amounts of energy as it consumes matter falling into it and causing the center to shine far brighter than its surroundings. This system is known as an active galactic nucleus.

Like most elliptical galaxies it appears rather featureless and inactive. However, Hubble observations surprised astronomers by revealing young stars and star clusters in M105, indicating that star formation is still taking place in what was thought to be a “dead” galaxy no longer capable of giving birth to new stars. Other Hubble observations measured the speeds of stars moving around the center of the galaxy. This demonstrated that a supermassive black hole resides at M105’s core.

Hubble also surprised astronomers by revealing a few young stars and clusters in Messer 105. Messier 105 is now thought to form roughly one Sun-like star every 10,000 years. Star-forming activity has also been spotted in a vast ring of hydrogen gas encircling both Messier 105 and its closest neighbor, the lenticular galaxy NGC 3384.

Charles Messier’s colleague Pierre Méchain discovered M105 in 1781 just a few days after locating M95 and M96. Yet M105 was not originally included in Messier’s catalog. It was added in 1947 after astronomer Helen S. Hogg found a letter written by Méchain describing the galaxy.

Best observed in the month of April, M105 has an apparent magnitude of 10.2 and can be spotted with a small telescope. Large telescopes will uncover two fainter galaxies (NGC 3384 and NGC 3389) close to the bright elliptical.

SpaceX Falcon 9 Makes 600th First Stage Landing

SpaceX Falcon 9 Rocket Makes 600th First Stage Landing

SpaceX: "That’s 496 landings on our droneships and 104 on our landing zones."

"First Orbital Class Rocket Capable of Reflight"
Falcon 9 is a partially "reusable, two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of people and payloads into Earth orbit and beyond. Reusability allows SpaceX to refly the most expensive parts of the rocket, which in turn drives down the cost of space access." Falcon 9's first stage incorporates nine Merlin engines.

The SpaceX Falcon 9 second stage does not typically land or get recovered. Unlike the first-stage booster that lands vertically for reuse, the second stage is designed to be expended after delivering the payload. It either burns up upon atmospheric re-entry or completes a controlled re-entry over the ocean to minimize space debris.

The first crewed test flight of NASA’s Artemis program lifted off from Launch Pad 39B at the agency’s Kennedy Space Center in Florida on April 1, 2026, carrying the first astronauts to travel to the Moon in more than half a century. 

During their nearly 10-day mission, the crew completed a record-setting lunar flyby, taking them 252,756 miles at their farthest distance from Earth and 4,067 miles above the lunar surface at their closest approach. 

Artemis II splashed down at 8:07 p.m. April 10 in the Pacific Ocean off the coast of San Diego. Following splashdown and recovery, the four crew members underwent post-mission medical evaluations before returning to shore and boarding an aircraft bound for Houston. Upon arrival, the crew was welcomed by and reunited with their families, friends, and agency workforce. The crew now will begin their postflight reconditioning, medical and human performance evaluations, and lunar science debriefs.

Under Artemis, NASA will send astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, and to build on our foundation for the first crewed missions to Mars.

NASA Rolls Out Artemis III Rocket Core Stage | Michoud Assembly Facility

NASA Rolls Out Artemis III Rocket Core Stage | Michoud Assembly Facility

NASA moved the core stage, or the largest section, of the Space Launch System (SLS) rocket that will launch the crewed Artemis III mission in 2027 from the agency’s Michoud Assembly Facility to the agency’s Pegasus barge in New Orleans, Louisiana, on April 20, 2026. The barge will ferry the top four-fifths—the section containing the liquid hydrogen tank, liquid oxygen tank, intertank, and forward skirt—of the SLS core stage to NASA’s Kennedy Space Center in Florida to complete outfitting and vertical integration.

Teams with NASA and Boeing, the SLS core stage lead contractor, used specialized transporters to guide the top four-fifths from the NASA rocket factory to Pegasus. Prior to the move, technicians added an engine section transportation simulator to the rocket stage for shipment to the Space Coast.

Next year’s Artemis III mission will launch astronauts to Earth orbit aboard the Orion spacecraft on top of SLS to test rendezvous and docking capabilities between Orion and commercial spacecraft needed to land Artemis IV astronauts on the Moon in 2028. NASA’s SLS is the only rocket capable of sending Orion, astronauts, and supplies to the Moon in a single launch. 

NASA will announce specifics on the Artemis III mission design and crew closer to the 2027 launch. It is anticipated that NASA's Artemis III mission in low Earth orbit will test integrated operations between the Orion spacecraft and one or both commercial landers from SpaceX and Blue Origin, respectively.

Explore The Trifid Nebula in Sagittarius | Hubble Space Telescope

Explore The Trifid Nebula in Sagittarius | Hubble Space Telescope

“Fly” through the NASA/ESA Hubble Space Telescope’s view of the Trifid Nebula. The video “floats” over the ridges of gas and dust and moves up toward Herbig-Haro 399 at the top of a brown cloud that resembles a head with horns. The thinner, irregular line pointing left formed from the ejections of an actively forming star. To its left is a small, faint pillar. Much of this pillar’s gas and dust has been blown away, but the densest material at the top persists.

The Trifid Nebula (cataloged as Messier 20 or M20 and as NGC 6514) is an H II region in the northwest of the Sagittarius constellation in a star-forming region in the Milky Way's Scutum–Centaurus Arm. It was discovered by Charles Messier on June 5, 1764. Its name means 'three-lobe'. The object is an unusual combination of an open cluster of stars, an emission nebula, a reflection nebula, and a dark nebula.

The colors in this image from the NASA/European Space Agency Hubble Space Telescope tell a story about density in the Trifid Nebula, a star-forming region about 5,000 light-years from Earth. The top left, where it is bright blue, has the smallest amount of dust. Here, powerful ultraviolet light stripped electrons from nearby gas, creating a glow, with winds creating a bubble by clearing out surrounding dust. An example of active cloud destruction is toward the top of the head-shaped area with two “horns.” Bright yellow gas streams upward where gas and dust are being destroyed.

Thicker dust appears dark brown, like mud. In the far-right corner, nearly pitch black, the dust is the densest. Fully formed stars (bright orange orbs) are scattered across the scene. Their light and stellar winds have also cleared the immediate areas around them.

“Cosmic Sea Slug” Appears in Hubble’s 36th Birthday Image (1990-2026)

“Cosmic Sea Slug” Appears in Hubble’s 36th Birthday Image (1990-2026)

NASA is celebrating the 36th anniversary of the Hubble Space Telescope with a stunning new look at the Trifid Nebula, a star-forming region about 5,000 light-years away. Powerful ultraviolet light from massive stars has carved out this glowing bubble, triggering new waves of star birth.

First imaged in 1997, Hubble revisits this scene nearly 30 years later with sharper vision. The image reveals a structure nicknamed the “Cosmic Sea Slug,” including a jet from Herbig-Haro 399, showing how young stars actively shape their surroundings.

Bright stars, dark dust, and glowing gas tell the story of stars forming and evolving. Over time, the nebula will fade, leaving only stars behind. For 36 years, Hubble has transformed how we see the universe, and it’s not done yet.

Sit back and relax as Hubble Senior Project Scientist, Dr. Jennifer Wiseman takes us on a tour of this beautiful image.

Wider View of Trifid Nebula: Vera Rubin Observatory Image with Hubble Close-up

Wider View of Trifid Nebula: Vera Rubin Observatory Image with Hubble Close-up

At left is a complete view of the Trifid Nebula (Messier 20 or M20) captured by the U.S. National Science Foundation-Department of Energy (NSF-DOE) Vera C. Rubin Observatory in Chile. A white box in the lower-left portion of the pink region shows the area the NASA/European Space Agency Hubble Space Telescope targeted, and Hubble’s new image is featured at right.

Rubin’s field of view is approximately 56 light-years across, while Hubble’s is about four light-years across.

The color assignments in the images vary based on the filters in the telescopes’ cameras. Rubin takes broadband images that capture the full visible spectrum to show natural colors in red, green, and blue. For this image, Hubble captured narrowband images of specific chemical elements. Sulfur, hydrogen, and oxygen were mapped to red, green, and blue, respectively, to make this composite image.

Image Description: A ground-based photo of the full Trifid Nebula is shown on the left half with an inset image from the Hubble Space Telescope at right. At left, an irregular mostly opaque circle takes up the majority of the view. The circle has a bright pink interior crossed with a few dark, jagged dust lanes. A significant region around that appears blue. The edges have shades of orange and brown with the star-filled black background of space peeking through. Hubble’s close-up is outlined just below center to the left. The top left is bright blue. Brown and amber colors run from top right through the center in irregular, overlapping lines to the bottom-center. At bottom right, the view is almost black. Tiny, amber-colored stars appear throughout the scene. Toward the left there is a prominent brown shape that looks like a head with two horns.

Close-up: The Trifid Nebula in Sagittarius Revisited | Hubble Space Telescope

Close-up: The Trifid Nebula in Sagittarius Revisited | Hubble Space Telescope

The Trifid Nebula (cataloged as Messier 20 or M20 and as NGC 6514) is an H II region in the northwest of the Sagittarius constellation in a star-forming region in the Milky Way's Scutum–Centaurus Arm. It was discovered by Charles Messier on June 5, 1764. Its name means 'three-lobe'. The object is an unusual combination of an open cluster of stars, an emission nebula, a reflection nebula, and a dark nebula.

The colors in this image from the NASA/European Space Agency Hubble Space Telescope tell a story about density in the Trifid Nebula, a star-forming region about 5,000 light-years from Earth. The top left, where it is bright blue, has the smallest amount of dust.

An example of active cloud destruction is toward the top of the head-shaped area with two “horns.” Bright yellow gas streams upward where gas and dust are being destroyed.

Thicker dust appears dark brown, like mud. In the far-right corner, nearly pitch black, the dust is the densest. Fully formed stars (bright orange orbs) are scattered across the scene. Their light and stellar winds have also cleared the immediate areas around them.

Over millions of years, the gas and dust that make up this nebula (also known as Messier 20 or M20) will disappear and only stars will remain.

Image Description: A tightly cropped Hubble view of a vast star-forming region known as the Trifid Nebula. The top left is bright blue. Brown and amber colors run from top right through the center in irregular, overlapping lines to the bottom-center. At bottom right, the view is almost black. Tiny, amber-colored stars appear throughout the scene. Toward the left there is a prominent brown shape that looks like a head with two horns. The left horn points left and is wavy. The right horn is triangular and points up. The brown dust continues, flowing down, as if along a back, and up toward the top right. A prominent line, about the same length as the left horn, appears below the middle of the body, and changes from orange to red. A small, separate semi-transparent pillar is left of the head. A few slightly larger, blue foreground stars with four diffraction spikes appear in the bottom half.

The Trifid Nebula in Sagittarius Revisited | Hubble Space Telescope

The Trifid Nebula in Sagittarius Revisited | Hubble Space Telescope

The Trifid Nebula (cataloged as Messier 20 or M20 and as NGC 6514) is an H II region in the northwest of the Sagittarius constellation in a star-forming region in the Milky Way's Scutum–Centaurus Arm. It was discovered by Charles Messier on June 5, 1764. Its name means 'three-lobe'. The object is an unusual combination of an open cluster of stars, an emission nebula, a reflection nebula, and a dark nebula.

The colors in this image from the NASA/European Space Agency Hubble Space Telescope tell a story about density in the Trifid Nebula, a star-forming region about 5,000 light-years from Earth. The top left, where it is bright blue, has the smallest amount of dust. Here, powerful ultraviolet light stripped electrons from nearby gas, creating a glow, with winds creating a bubble by clearing out surrounding dust. An example of active cloud destruction is toward the top of the head-shaped area with two “horns.” Bright yellow gas streams upward where gas and dust are being destroyed.

Thicker dust appears dark brown, like mud. In the far-right corner, nearly pitch black, the dust is the densest. Fully formed stars (bright orange orbs) are scattered across the scene. Their light and stellar winds have also cleared the immediate areas around them.

Over millions of years, the gas and dust that make up this nebula (also known as Messier 20 or M20) will disappear and only stars will remain.

Image Description: A tightly cropped Hubble view of a vast star-forming region known as the Trifid Nebula. The top left is bright blue. Brown and amber colors run from top right through the center in irregular, overlapping lines to the bottom-center. At bottom right, the view is almost black. Tiny, amber-colored stars appear throughout the scene. Toward the left there is a prominent brown shape that looks like a head with two horns. The left horn points left and is wavy. The right horn is triangular and points up. The brown dust continues, flowing down, as if along a back, and up toward the top right. A prominent line, about the same length as the left horn, appears below the middle of the body, and changes from orange to red. A small, separate semi-transparent pillar is left of the head. A few slightly larger, blue foreground stars with four diffraction spikes appear in the bottom half.
