Pan: Cluster in the Cloud Globular Cluster NGC 2210 | Hubble
Pan: Cluster in the Cloud Globular Cluster NGC 2210 | Hubble
This striking image shows the densely packed globular cluster known as NGC 2210. It is situated in the Large Magellanic Cloud (LMC). The LMC lies about 157,000 light-years from Earth. It is a so-called satellite galaxy of the Milky Way, meaning that the two galaxies are gravitationally bound. Globular clusters are very stable, tightly bound clusters of thousands or even millions of stars. Their stability means that they can last a long time, and therefore globular clusters are often studied in order to investigate potentially very old stellar populations.
In fact, 2017 research that made use of this data used to build this image revealed that a sample of LMC globular clusters were incredibly close in age to the oldest stellar clusters found in the Milky Way’s halo. They found that NGC 2210 is around 11.6 billion years old. Although this is only a couple of billion years younger than the Universe itself, it makes NGC 2210 by far the youngest globular cluster in their sample. All other LMC globular clusters studied in the same work were found to be older, with four of them over 13 billion years old. This is interesting, because it tells astronomers that the oldest globular clusters in the LMC formed contemporaneously with the oldest clusters in the Milky Way, although the two galaxies formed independently.
As well as being a source of interesting research, this old-but-relatively-young cluster is also extremely beautiful with its highly concentrated population of stars. The night sky would look very different from the perspective of an inhabitant of a planet orbiting one of the stars in a globular cluster’s center. The sky would appear to be stuffed full of stars, in a stellar environment that is thousands of times more crowded than our own.
Image Description: A dense cluster of stars. It is brightest and most crowded in the center, where the stars are mostly a cool white color. Moving out towards the edges the stars become more spread out and reddish until a noticeable ‘edge’ to the cluster is reached. Beyond that edge there are still many stars, more disorganized and seen on a black background. A number of stars appear to be in front of the cluster.

China's iSpace Hyperbola-2 Commercial Rocket: Vertical Takeoff & Landing Test
China's iSpace Hyperbola-2 Commercial Rocket: Vertical Takeoff & Landing Test
This second successful hop test “marks a major breakthrough in China’s commercial aerospace industry in reusable launch vehicle technology. It also signals the charge for China’s aerospace sector to catch up with the world’s most advanced levels in reusable launch vehicle technology” an iSpace statement read.
The test is part of the company’s plan to develop the Hyperbola-3 rocket with a reusable first stage. iSpace is skipping the previously-planned smaller Hyperbola-2, the company stated at the 9th China (International) Commercial Aerospace Forum in July 2023.
The company is targeting a first flight of the 13.4-metric-ton to low Earth orbit (LEO) Hyperbola-3 rocket in 2025. A demonstration of reuse will follow in 2026. The 69-meter-long rocket will be able to lift 8.5 tons to LEO in reusable mode. iSpace says it aims to conduct 25 Hyperbola-3 launches per year by 2030.
The Hyperbola-3B, a triple-core version of the rocket, akin to the Falcon Heavy in configuration, will be capable of carrying no less than 15 tons to LEO, according to iSpace.
iSpace made history as the first privately-funded Chinese company to reach orbit in 2019 with the solid-fueled Hyperbola-1 rocket. The company however suffered three consecutive failures with the rocket, before a successful return to flight earlier this year. Further launches of the solid rocket are expected in the coming year, despite competition from Galactic Energy’s Ceres-1 and Expace’s Kuaizhou rockets.
iSpace is not the only Chinese company working on reusable rockets. Galactic Energy recently performed a hop test with a jet engine-powered article. CAS Space, a spin-off from the Chinese Academy of Sciences, has likewise conducted such tests to verify algorithms. Deep Blue Aerospace completed a successful kilometer-level rocket launch and landing test in 2022.
Another competitor, Space Pioneer, is planning to launch its Tianlong-3 rocket in the first half of 2024. The rocket will be comparable to Falcon 9 in launch capability and eventually to be made reusable. Landspace’s methalox Zhuque-2 is also expected to be converted for reusability.
China opened up its space sector to private and commercial activity in 2014. This is seen as largely in reaction to the explosion of commercial space in the U.S. The central government has since implemented policies and published guidance to support the development of commercial space.
2023 has been a notable year for China’s commercial launch companies. CAS Space, Galactic Energy, iSpace, Expace, Space Pioneer and Landspace have all reached orbit. These include first Chinese commercial liquid propellant launch successes, achieved by Space Pioneer and Landspace.
The Tiangong Space Station is expected to provide an opportunity for commercial launch vehicles to gain contracts to deliver cargo. The national Guowang LEO broadband megaconstellation is also expected to provide opportunities for commercial actors.

Planet Mars: The Day the Solar Wind Disappeared | NASA Goddard
Planet Mars: The Day the Solar Wind Disappeared | NASA Goddard
In December 2022, NASA’s Mars-orbiting MAVEN mission observed the dramatic and unexpected “disappearance” of the solar wind, a stream of charged particles that continuously emanates from the Sun. This was caused by a special type of solar event that was so powerful, it created a void in its wake as it traveled through the solar system. The Martian atmosphere and magnetosphere expanded by thousands of kilometers in response, causing the solar wind to temporarily vanish from Mars. MAVEN’s observations of this dramatic event are helping scientists to better understand the physics that drive atmospheric and water loss at Mars.

All Lined Up: Interacting Galaxy System Arp-Madore 2105-332 | Hubble
All Lined Up: Interacting Galaxy System Arp-Madore 2105-332 | Hubble
Both the galaxies are of a type known as emission-line galaxies. This simply means that, when observed with spectrometers, the spectra of both galaxies exhibit characteristic bright peaks, known as emission lines. This is distinct from, for example, absorption-line galaxies whose spectra contain distinct gaps, known as absorption lines. Emission lines are produced when gases are very hot, and therefore have sufficient energy that the atoms and molecules are ‘excited’ and emit light. In other words, emission-line galaxies are highly energetic places, marking them out as likely hotbeds of star formation.
As with many galaxy types, categorizing a galaxy as an emission-line galaxy does not exclude it from having other descriptions that refer to its other properties. Arp-Madore 2105-332, for example, is also a ‘peculiar’ galaxy, reflecting the atypical shapes of its two constituent galaxies.
Image Description: A pair of interacting galaxies, one smaller than the other. Each has a bright spot at the center and two loosely-wound spiral arms, with threads of dark dust following the arms. They appear as a broad, soft glow in which individual stars can’t be seen. A number of bright stars and smaller, background galaxies can also be seen — three such galaxies lie in a vertical line below the right-hand galaxy of the pair.

Zooming into Supernova Remnant Cassiopeia A | James Webb Space Telescope
Zooming into Supernova Remnant Cassiopeia A | James Webb Space Telescope
This zoom-in video shows the relative location of supernova remnant Cassiopeia A (Cas A) in the sky. It begins with a ground-based photo by the late astrophotographer Akira Fujii. As it zooms into smaller portions of the sky, it fades into an image from the Digital Sky Survey. It ends by crossfading into an image of Cas A from NIRCam (Near-Infrared Camera) on NASA’s James Webb Space Telescope, with added borders from a NASA’s Hubble Space Telescope image.
A new high-definition image from NASA’s James Webb Space Telescope’s near-infrared camera (NIRCam) unveils intricate details of supernova remnant Cassiopeia A (Cas A), and shows the expanding shell of material slamming into the gas shed by the star before it exploded about 300 years ago.
The most noticeable colors in Webb’s newest image are clumps of bright orange and light pink that make up the inner shell of the supernova remnant. These tiny knots of gas, comprised of sulfur, oxygen, argon, and neon from the star itself, are only detectable by NIRCam’s exquisite resolution, and give researchers a hint at how the dying star shattered like glass when it exploded.
The outskirts of the main inner shell looks like smoke from a campfire. This marks where ejected material from the exploded star is ramming into surrounding circumstellar material. Researchers say this white color is light from synchrotron radiation. It is generated by charged particles traveling at extremely high speeds spiraling around magnetic field lines.
There are also several light echoes visible in this image. This is where light from the star’s long-ago explosion has reached, and is warming, distant dust, that is glowing as it cools down.

Spiral Galaxy NGC 3021: A Cosmological Measuring Tape | Hubble
Spiral Galaxy NGC 3021: A Cosmological Measuring Tape | Hubble
Among many other types of stars, this galaxy contains Cepheid variable stars. These can be used work out the distance to the galaxy. Such stars pulsate at a rate that is closely related to their intrinsic brightness, so measurements of their rate of pulsation and their observed brightness give astronomers enough information to calculate the distance to the galaxy itself.
Cepheids are also used to calibrate an even brighter distance marker, that can be used over greater distances: Type Ia supernovae. One of these bright exploding stars was observed in NGC 3021, back in 1995.
In addition, the supernova in NGC 3021 was also used to refine the measurement of what is known as the Hubble constant. The value of this constant defines how fast the Universe is expanding. The more accurately we know it, the more we can understand about the evolution of the Universe in the past, as well as in the future. Thus, there is much more to this galaxy than just a pretty spiral.

Nebula NGC 2626 in Vela | SMARTS Telescope
Reflection nebulae are not luminous themselves, but they reflect light from a nearby star or stars. The light scatters off the dust particles in the nebulae. This often results in reflection nebulae having a blue tint, because blue light scatters more efficiently. This is the same phenomenon that makes the sky on Earth appear blue—the laws of physics are the same throughout our Universe! The red nebulosities are glowing hydrogen gas.
