NASA Astronaut Nichole Ayers: Hair Wash Day | International Space Station

NASA Astronaut Nichole Ayers: Hair Wash Day | International Space Station

To wash their hair in space, astronauts can use a special no-rinse shampoo, a water-filled pouch with a one-way valve, and a towel. They squirt warm water onto their scalp and work it through to the ends of their hair, applying the shampoo and then drying it with a towel. The water used in the process is recycled. This method ensures that astronauts maintain their hygiene needs while living in space.

Highlights of Galaxy Cluster Abell 3667 in Pavo | Victor Blanco Telescope

Highlights of Galaxy Cluster Abell 3667 in Pavo | Victor Blanco Telescope

Abell 3667—an actively merging galaxy cluster—is featured in this image assembled from over 28 hours of observations with the 570-megapixel Department of Energy-fabricated Dark Energy Camera, mounted on the U.S. National Science Foundation (NSF) Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, a Program of NSF NOIRLab. This collage shows examples of Abell 3667's interesting features.

1. Jellyfish Galaxy JO171
Similar to the iconic Hoag’s Object, JO171 is an example of a ring galaxy, characterized by a completely detached ring of young stars surrounding a central old spheroid. JO171’s fall into the dense Abell 3667 galaxy cluster is stripping it of gas, creating the striking jellyfish-like tendrils seen trailing off to one side of the galaxy. Analysis of the galaxy’s stellar population and its gas and stellar dynamics shows that the origin of the ring is related to an interaction with another galaxy in the distant past, prior to its accretion onto Abell 3667. More recently, since infall into the cluster, the gas in the ring has been stripped by ram pressure, causing the quenching of star formation in the stripped half of the ring. This is the first observed case of ram-pressure stripping in action in a ring galaxy. Both of the events (accretion and stripping) caused dramatic transformations in this galaxy.

2. Jellyfish Galaxy LEDA 64246
LEDA 64246 is another example of extended galaxy tails formed by ram-pressure stripping. Their blue glow indicates that the stripping has triggered star formation in the trails.

3. Brightest cluster galaxy IC 4965 and infalling group
The central galaxy in this cutout is referred to as the brightest cluster galaxy (BCG). The formation of BCGs has been an astronomical mystery for decades. The mystery has been partially answered by the detection of intracluster light. This provides evidence that BCGs generally form through the gradual stripping of stars from less massive galaxies in the cluster, which then accrete onto the BCG.

4. Seyfert Galaxy NGC 6862
NGC 6862 is a Seyfert galaxy that is partially obscured by Milky Way cirrus, or integrated flux nebulae.

Deep View of Galaxy Cluster Abell 3667 in Pavo | Victor Blanco Telescope

Deep View of Galaxy Cluster Abell 3667 in Pavo | Victor Blanco Telescope

The final image shows Abell 3667—an actively merging galaxy cluster. It was assembled from over 28 hours of observations with the 570-megapixel Department of Energy-fabricated Dark Energy Camera, mounted on the U.S. National Science Foundation (NSF) Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, a Program of NSF NOIRLab.

Within Abell 3667, two smaller galaxy clusters are actively merging together, evidenced by the glowing bridge (yellow) of stars stretching across the center of this image. This bridge connects the hearts of the two galaxy clusters, known as their brightest cluster galaxies, and forms out of material stripped from the galaxies as they merge to form one massive conglomerate. 

Galaxy clusters are among the largest structures in our Universe, consisting of hundreds or thousands of galaxies that have become gravitationally bound together over billions of years. Astrophysicists have long been eager to understand the formation of these imposing structures. The histories of galaxy clusters not only help us understand how the Universe formed, but they also provide constraints on the properties of dark matter—an invisible material that does not emit or reflect light and is found in high concentrations around clusters of galaxies.

One clue astronomers look for to understand the history of a galaxy cluster is intracluster light—the faint glow emitted by stars that have been stripped from their original galaxies by the immense gravity of a forming galaxy cluster. These stars serve as whispering evidence of past galactic interactions, though most existing telescopes and cameras struggle to capture them.

Comparing Webb infrared image with Hubble Ultra Deep Field | NASA/ESA

Comparing Webb infrared image with Hubble Ultra Deep Field | NASA/ESA

This video provides a unique comparison to highlight the visible and infrared observations of one of the most iconic regions of the sky, the Hubble Ultra Deep Field. 

When the original Hubble Ultra Deep Field was released by the NASA/European Space Agency Hubble Space Telescope in 2004, it was the deepest image of the Universe ever taken. In 2025, Webb’s new view of this field is now one of the deepest views ever obtained of the Universe to date.

By returning to this legacy field first made famous by Hubble, Webb is continuing and expanding the deep field tradition—revealing new details, uncovering previously hidden galaxies, and offering fresh insights into the formation of the first cosmic structures.

The first image shown in this video a new infrared view of this field through the eyes of two of Webb’s instruments. The result is a detailed view that reveals thousands of distant galaxies, some dating back to the earliest periods of cosmic history. The field, known as the MIRI Deep Imaging Survey (MIDIS) region, was observed with the shortest-wavelength filter of Webb’s Mid-Infrared Instrument (MIRI) for nearly 41 hours. Combined with data from Webb’s Near-Infrared Camera (NIRCam), this image allows astronomers to explore how galaxies formed and evolved over billions of years.

The second image shown in this video a portion of the Hubble eXtreme Deep Field, or XDF, as seen by the NASA/ESA Hubble Space Telescope. This image, originally released in 2012, was taken of a patch of sky within the original Hubble Ultra Deep Field, released in 2004.

Close-up: A deep field in Fornax: Thousands of distant galaxies | Webb Telescope

This image from the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope revisits one of the most iconic regions of the sky, the Hubble Ultra Deep Field, through the eyes of two of Webb’s instruments. The result is a detailed view that reveals thousands of distant galaxies, a portion dating back to the earliest periods of cosmic history.

The field shown here, known as the MIRI Deep Imaging Survey (MIDIS) region, was observed with the three shortest-wavelength filters of Webb’s Mid-Infrared Instrument (MIRI) for nearly 100 hours in total. This included Webb's longest observation of an extragalactic field in one filter so far, producing one of the deepest views ever obtained of the Universe. Combined with data from Webb’s Near-Infrared Camera (NIRCam), this image allows astronomers to explore how galaxies formed and evolved over billions of years.

These deep observations have revealed more than 2500 sources in this tiny patch of sky. Among them are hundreds of extremely red galaxies. These are likely massive, dust-obscured systems or evolved galaxies with mature stars that formed early in the Universe’s history. Thanks to Webb’s sharp resolution, even at mid-infrared wavelengths, researchers can resolve the structures of many of these galaxies and study how their light is distributed, shedding light on their growth and evolution.

In this image, the colors that have been assigned to kinds of infrared light highlight the fine distinctions astronomers can make with this deep data. Orange and red represent the longest mid-infrared wavelengths. The galaxies in these colors have extra features—such as high concentrations of dust, copious star formation, or an active galactic nucleus (AGN) at their center, emitting more of this farther infrared light. Small, greenish-white galaxies are particularly distant with high redshift. This shifts their light spectrum into the peak mid-infrared wavelengths of the data, depicted in white and green. Most of the galaxies in this image lack any such mid-infrared boosting features, leaving them most bright at shorter near-infrared wavelengths, depicted with blue and cyan colors.

By returning to this legacy field first made famous by the NASA/European Space Agency Hubble Space Telescope, Webb is continuing and expanding the deep field tradition—revealing new details, uncovering previously hidden galaxies, and offering fresh insights into the formation of the first cosmic structures.

Image Description: An area of deep space with thousands of galaxies in a variety of shapes and sizes on a black background. Most are circles or ovals with a few spirals. More distant galaxies are smaller, down to being mere dots, while closer galaxies are larger and a number appear to be glowing. Red and orange galaxies contain more dust or more stellar activity.

Ghost Planetary Nebula (GPN) SDSO 1 & Neighboring Andromeda Galaxy

Ghost Planetary Nebula (GPN) SDSO 1 & Neighboring Andromeda Galaxy

What are these gigantic blue arcs near the Andromeda Galaxy (M31)? 

Discovered in 2022 by amateur astronomers, the faint arcs—dubbed SDSO 1—span nearly the same angular size as M31 itself. At first, their origin was a mystery. Are they actually near the Andromeda Galaxy, or alternatively near to our Sun? Now, over 550 hours of combined exposure and a collaboration between amateur and professional astronomers has revealed strong evidence for their true nature: SDSO 1 is not intergalactic, but a new class of planetary nebula within our galaxy. Dubbed a Ghost Planetary Nebula (GPN), SDSO 1 is the first recognized member of a new subclass of faded planetary nebulas, along with seven others also recently identified. Shown in blue are extremely faint oxygen emission from the shock waves, while the surrounding red is a hydrogen-emitting trail that indicates the GPN's age.

Russell, and H.E. Justin Sun—the winning bidder for the first New Shepard seat in 2021. Including today’s crew, New Shepard has now flown 75 people into space, including five people who have flown twice."

The Kármán line is a conventional definition of the edge of space; it is widely but not universally accepted. The international record-keeping body Fédération aéronautique internationale (FAI) defines the Kármán line at an altitude of 100 kilometers (54 nautical miles; 62 miles; 330,000 feet) above mean sea level. The Kármán line is mainly used for legal and regulatory purposes of differentiating between aircraft and spacecraft.

“It was an honor to see so many nations represented on our flight today,” said Phil Joyce, SVP, New Shepard. “The view of our fragile planet from space has a unifying effect on all who witness it, and I am always eager to see how our astronauts use this experience for the benefit of Earth.”
