Credit: NASA NASA has selected Rocket Lab USA Inc. of Long Beach, California, to launch the agency’s Aspera mission, a SmallSat to study galaxy formation and evolution, providing new insights into how the universe works.
The selection is part of NASA’s Venture-Class Acquisition of Dedicated and Rideshare (VADR) launch services contract. This contract allows the agency to make fixed-price indefinite-delivery/indefinite-quantity launch service task order awards during VADR’s five-year ordering period, with a maximum total contract value of $300 million.
Through the observation of ultraviolet light, Aspera will examine hot gas in the space between galaxies, called the intergalactic medium. The mission will study the inflow and outflow of gas from galaxies, a process thought to contribute to star formation.
Aspera is part of NASA’s Pioneers Program in the Astrophysics Division at NASA Headquarters in Washington, which funds compelling astrophysics science at a lower cost using small hardware and modest payloads. The principal investigator for Aspera is Carlos Vargas at the University of Arizona in Tucson. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages the VADR contract.

Hubble Pinpoints Young Stars in Spiral Galaxy
This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 1317. ESA/Hubble & NASA, J. Lee and the PHANGS-HST Team In this image, the NASA/ESA Hubble Space Telescope peers into the spiral galaxy NGC 1317 in the constellation Fornax, located more than 50 million light-years from Earth. Visible in this galaxy image is a bright blue ring that hosts hot, young stars. NGC 1317 is one of a pair, but its rowdy larger neighbor, NGC 1316, lies outside Hubble’s field of view. Despite the absence of its neighboring galaxy, this image finds NGC 1317 accompanied by two objects from very different parts of the universe. The bright point ringed with a crisscross pattern is a star from our own galaxy surrounded by diffraction spikes, whereas the redder elongated smudge is a distant galaxy lying far beyond NGC 1317.
The data presented in this image are from a vast observing campaign of hundreds of observations from Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys. Combined with data from the ALMA array in the Atacama Desert, these observations help astronomers chart the connections between vast clouds of cold gas and the fiercely hot, young stars that form within them. ALMA’s unparalleled sensitivity at long wavelengths identified vast reservoirs of cold gas throughout the local universe, and Hubble’s sharp vision pinpointed clusters of young stars, as well as measuring their ages and masses.
Often the most exciting astronomical discoveries require this kind of telescope teamwork, with cutting-edge facilities working together to provide astronomers with information across the electromagnetic spectrum. The same applies to Hubble’s observations that laid the groundwork for the NASA/ESA/CSA James Webb Space Telescope’s scientific observations.

X-ray: NASA/CXC/Northwestern Univ./F. Yusef-Zadeh et al; Radio: NRF/SARAO/MeerKat; Image Processing: NASA/CXC/SAO/N. Wolk Astronomers have discovered a likely explanation for a fracture in a huge cosmic “bone” in the Milky Way galaxy, using NASA’s Chandra X-ray Observatory and radio telescopes.
The bone appears to have been struck by a fast-moving, rapidly spinning neutron star, or pulsar. Neutron stars are the densest known stars and form from the collapse and explosion of massive stars. They often receive a powerful kick from these explosions, sending them away from the explosion’s location at high speeds.
Enormous structures resembling bones or snakes are found near the center of the galaxy. These elongated formations are seen in radio waves and are threaded by magnetic fields running parallel to them. The radio waves are caused by energized particles spiraling along the magnetic fields.
X-ray: NASA/CXC/Northwestern Univ./F. Yusef-Zadeh et al; Radio: NRF/SARAO/MeerKat; Image Processing: NASA/CXC/SAO/N. Wolk This new image shows one of these cosmic “bones” called G359.13142-0.20005 (G359.13 for short), with X-ray data from Chandra (colored blue) and radio data from the MeerKAT radio array in South Africa (colored gray). Researchers also refer to G359.13 as the Snake.
Examining this image closely reveals the presence of a break, or fracture, in the otherwise continuous length of G359.13 seen in the image. The combined X-ray and radio data provides clues to the cause of this fracture.
Astronomers have now discovered an X-ray and radio source at the location of the fracture, using the data from Chandra and MeerKAT and the National Science Foundation’s Very Large Array. A likely pulsar responsible for these radio and X-ray signals is labeled. A possible extra source of X-rays located near the pulsar may come from electrons and positrons (the anti-matter counterparts to electrons) that have been accelerated to high energies.
The researchers think the pulsar likely caused the fracture by smashing into G359.13 at a speed between one million and two million miles per hour. This collision distorted the magnetic field in the bone, causing the radio signal to also become warped.
At about 230 light-years long, G359.13 is one of the longest and brightest of these structures in the Milky Way. To put this into context, there are more than 800 stars within that distance from Earth. G359.13 is located about 26,000 light-years from Earth, near the center of the Milky Way.
A paper describing these results appeared in the May 2024 issue of the Monthly Notices of the Royal Astronomical Society and is available here. The authors of the study are Farhad Yusuf-Zadeh (Northwestern University), Jun-Hui Zhao (Center for Astrophysics | Harvard & Smithsonian), Rick Arendt (University of Maryland, Baltimore County), Mark Wardle (Macquarie University, Australia), Craig Heinke (University of Alberta), Marc Royster (College of the Sequoias, California), Cornelia Lang (University of Iowa), and Joseph Michail (Northwestern).

Visual Description
This release features two composite images of a long, thin, cosmic structure. With the structure’s vertical orientation, seemingly fragile dimensions, and pale grey color against the blackness of space, the images resemble medical X-rays of a long, thin, bone. The main image shows the structure in its entirety. The inset image is an annotated close-up highlighting an apparent fracture in the bone-like structure.
The structure, called G359.13, or “The Snake”, is a Galactic Center Filament. These filament formations are threaded by parallel magnetic fields, and spiraling, energized particles. The particles cause radio waves, which can be detected by radio arrays, in this case by the MeerKAT array in South Africa.
In the first composite image, the largely straight filament stretches from the top to the bottom of the vertical frame. At each end of the grey filament is a hazy grey cloud. The only color in the image is neon blue, found in a few specks which dot the blackness surrounding the structure. The blue represents X-rays seen by NASA’s Chandra X-ray Observatory.
In the annotated close-up, one such speck appears to be interacting with the structure itself. This is a fast-moving, rapidly spinning neutron star, otherwise known as a pulsar. Astronomers believe that this pulsar has struck the filament halfway down its length, distorting the magnetic field and radio signal.
In both images, this distortion resembles a small break, or spur, in the bone-like filament.

6 Min Read NASA’s Chandra Releases New 3D Models of Cosmic Objects
New three-dimensional (3D) models of objects in space have been released by NASA’s Chandra X-ray Observatory. These 3D models allow people to explore — and print — examples of stars in the early and end stages of their lives. They also provide scientists with new avenues to investigate scientific questions and find insights about the objects they represent.
These 3D models are based on state-of-the-art theoretical models, computational algorithms, and observations from space-based telescopes like Chandra that give us accurate pictures of these cosmic objects and how they evolve over time.
However, looking at images and animations is not the only way to experience this data. The four new 3D printable models of Cassiopeia A (Cas A), G292.0+1.8 (G292), Cygnus Loop supernova remnants, and the star known as BP Tau let us experience the celestial objects in the form of physical structures that will allow anyone to hold replicas of these stars and their surroundings and examine them from all angles.
Cassiopeia A (Cas A)
Using NASA’s James Webb Space Telescope, astronomers uncovered a mysterious feature within the remnant, nicknamed the “Green Monster,” alongside a puzzling network of ejecta filaments forming a web of oxygen-rich material. When combined with X-rays from Chandra, the data helped astronomers shed light on the origin of the Green Monster and revealed new insights into the explosion that created Cas A about 340 years ago, from Earth’s perspective.

3D Model of Cassiopeia AINAF-Osservatorio Astronomico di Palermo/Salvatore Orlando BP Tau
X-ray: NASA/CXC/SAO; Optical: PanSTARRS; Image Processing: NASA/CXC/SAO/N. Wolk This 3D model shows a star less than 10 million years old that is surrounded by a disk of material. This class of objects is known as T Tauri stars, named after a young star in the Taurus star-forming region. The model describes the effects of multiple flares, or outbursts that are detected in X-rays by Chandra from one T Tauri star known as BP Tau. These flares interact with the disk of material and lead to the formation of an extended outer atmosphere composed by hot loops, connecting the disk to the developing star.

X-ray: NASA/SAO/CXC; Optical: John Stone (Astrobin); Image Processing: NASA/SAO/CXC/L. Frattre, N. Wolk The Cygnus Loop (also known as the Veil Nebula) is a supernova remnant, the remains of the explosive death of a massive star. This 3D model is the result of a simulation describing the interaction of a blast wave from the explosion with an isolated cloud of the interstellar medium (that is, dust and gas in between the stars). Chandra sees the blast wave and other material that has been heated to millions of degrees. The Cygnus Loop is a highly extended, but faint, structure on the sky: At three degrees across, it has the diameter of six full moons.

3D Model of Cygnus LoopINAF-Osservatorio Astronomico di Palermo/Salvatore Orlando G292.0+1.8
X-ray: NASA/CXC/SAO; Optical:NSF/NASA/DSS; Image Processing This is a rare type of supernova remnant observed to contain large amounts of oxygen. The X-ray image of G292.0+1.8 from Chandra shows a rapidly expanding, intricately structured field left behind by the shattered star. By creating a 3D model of the system, astronomers have been able to examine the asymmetrical shape of the remnant that can be explained by a “reverse” shock wave moving back toward the original explosion.

Visual Description
This release features visualizations of three supernova remnants and one star. Each is rendered as a composite image, and as a digital 3-dimensional model, presented in separate short video clips. The composite images are two dimensional and static, but the digital models rotate, showcasing their three-dimensionality.
The first featured supernova is Cassiopeia A. In the X-ray, optical, and infrared composite image, the debris from an exploded star resembles a round purple gas cloud, marbled with streaks of golden light. In the rotating, 3D model, the purple gas cloud is depicted as a flat disk, like a record or CD. Bursting out the front and back of the disk is an orange and white shape similar to a ball of coral, or a head of cauliflower lined with stubby tendrils. Most of the ball, and the majority of the tendrils, appear on one side of the disk. On the opposite side, the shape resembles dollops of thick whipped cream.
Next in the release is a star known as BP Tau. BP Tau is a developing star, less than 10 million years old, and prone to outbursts or flares. These flares interact with a disk of material that surrounds the young star, forming hot loops of extended atmosphere. In the composite image, BP Tau resembles a distant, glowing white dot surrounded by a band of pink light. The rotating, 3D model is far more dynamic and intriguing! Here, the disk of material resembles a large blue puck with round, ringed, concave surfaces. At the heart of the puck is a small, glowing red orb: the developing star. Shooting out of the orb are long, thin, green strands: the flares. Also emerging from the orb are orange and pink petal-shaped blobs: the loops of extended atmosphere. Together, the orb, strands, and petals resemble an exotic flowering orchid.
The third celestial object in this release is the supernova remnant called Cygnus Loop. In the composite image, the remnant resembles a wispy cloud in oranges, blues, purples, and whites, shaped like a backwards letter C. The 3D model examines this cloud of interstellar material interacting with the superheated, supernova blast wave. In the 3D model, the Cygnus Loop resembles a bowl with a thick base, and a wedge cut from the side like a slice of pie. The sides of the bowl are rendered in swirled blues and greens. However, inside the thick base, revealed by the wedge-shaped cut, are streaks of red and orange. Surrounding the shape are roughly parallel thin red strands, which extend beyond the top and bottom of the digital model.
The final supernova featured in this release is G292.0+1.8. The composite image depicts the remnant as a bright and intricate ball of red, blue, and white X-ray gas and debris set against a backdrop of gleaming stars. In the 3D model, the remnant is rendered in translucent icy blue and shades of orange. Here, the rotating shape is revealed to be somewhat like a bulbous arrowhead, or perhaps an iceberg on its side.
