Comet C/2025 R3 Panstarrs: View from Spain

Comet C/2025 R3 Panstarrs: View from Spain

Astrophotographer Frank Niebling: "Comet Panstarrs shows nice structures: It has now several jets that result in separate gas tails. These were interacting with a turbulence in the solar wind in the morning of 28.03.2026 and curled the gas tail."

Discovered by the Pan-STARRS survey in September 2025, the comet is diving toward its closest approach to the sun (0.50 AU) on April 19, 2026, bringing it well inside the orbit of Venus. If current trends continue, the comet could brighten to magnitude +2, easily seen and photographed in the pre-dawn sky.

The comet's brightness will receive a further boost between April 24-25 when it passes almost directly between Earth and the Sun. The process is called "forward scattering." Sunlight passing through the comet's dusty atmosphere could be amplified 100-fold or more.

We will not be able to see the April 24 surge from Earth. The comet will be too close to the Sun. However, coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) will have a great view of what could briefly become a truly magnificent object.

China Launches Lijian-2 Commercial Rocket: Key to Next-gen Space Cargo System

China Launches Lijian-2 Commercial Rocket: Key to Next-gen Space Cargo System

Modular and universal design enables efficient production and launch for Lijian-2 (Kinetica-2) carrier rockets, said a designer as a Lijian-2 Y1 carrier rocket with three satellites onboard blasted off at 19:00 (Beijing Time) from a commercial aerospace innovation pilot zone in northwest China and sent the satellites into the planned orbit on March 30, 2026, including the New March-02 Satellite, also known as the Qingzhou prototype test spacecraft.

With a low Earth orbit payload capacity of 12 tonnes, the rocket is fully equipped to meet the demands of space station cargo missions. However, for commercial spaceflight, high payload capacity alone is not enough. The Lijian-2 is able to deliver impressive performance thanks to its design innovations.

A closer look at the Lijian-2 reveals that its core stage and two boosters appear nearly identical. This is no coincidence but a deliberate "universal" design known as the "universal booster core" configuration. This approach allows major components of the rocket to be mass-produced, significantly streamlining the manufacturing process.

"From the very beginning of its design, the Lijian-2 followed a philosophy of large quantity and mass production. That is why the appearance of the rocket’s units is highly similar. The critical feature of this rocket is that the core stage and the boosters are designed to be identical in configuration," said Lian Jie, deputy chief designer of Lijian-2 carrier rocket of CAS Space, a commercial spaceflight company established by the Institute of Mechanics under the Chinese Academy of Sciences (CAS).

According to Lian, the greatest advantages of this design lie in its flexibility and efficiency. If a component encounters an issue, it can be quickly replaced like a standard part—a key feature that supports the development of high-frequency launch capability.

"If a problem occurs during the launch, we can quickly take a booster produced in the same batch to replace the faulty one, so as to ensure a smooth launch as scheduled," he said.

Developed by Chinese commercial space firm CAS Space, Lijian-2 is China's first to adopt a Common Booster Core (CBC) configuration. The Lijian-2 is a medium-lift, liquid-fuel rocket and the second launch vehicle developed by CAS Space, following the Lijian-1. It is the company's first liquid-propellant rocket, and is tasked with supporting China's large-scale satellite deployment and low-cost cargo transportation for the China Space Station.

The Coma Galaxy Cluster: Clusters within Clusters in Coma Berenices | Hubble

The Coma Galaxy Cluster: Clusters within Clusters in Coma Berenices | Hubble

This image, from the NASA/European Space Agency Hubble Space Telescope’s Advanced Camera for Surveys (ACS), reveals thousands of globular clusters lying at the core of a galaxy cluster. It was created by a Hubble survey that drew on data from three of the telescope’s separate observing programs to explore the center of the Coma cluster, a huge gathering of over 1,000 galaxies, about 320 million light-years away, all bound together by gravity.

Astronomers spotted over 22,000 globular clusters. A number of these have formed a bridge connecting a pair of well-known interacting galaxies, such as NGC 4889 and NGC 4874. A globular cluster is a spherical group of stars that usually orbits a galaxy as a self-contained satellite. However, the globular clusters studied here are another type, intracluster globular clusters. Specifically, these are globular clusters that are not bound to an individual galaxy, but to a galaxy cluster—in this case, Coma.

While globular clusters orbiting our Milky Way reveal themselves as sparkling spherical assemblies of densely packed stars, at the distance of the Comla cluster, they only appear as tiny dots of light, even to Hubble's advanced vision. However, a characteristic feature of globular clusters is their color; since the stars in any given cluster all formed at around the same time and from the same “stuff”, they usually have a consistent color. In this way, the astronomers were able to identify the clusters—and rule out background galaxies lying in the same region of sky—by analyzing their color and size, painting a beautiful family portrait of Coma and its clusters.

With the help of the identified globular clusters astronomers can map the distribution of matter and — even more important—of dark matter in the Coma cluster. The Coma Cluster was one of the first places where observed gravitational anomalies indicated the existence of dark matter.

Giant Elliptical Galaxy NGC 4874 in Coma Berenices | Hubble

Giant Elliptical Galaxy NGC 4874 in Coma Berenices | Hubble

In the center of a rich cluster of galaxies located in the direction of the constellation of Coma Berenices, lies a galaxy surrounded by a swarm of star clusters. NGC 4874 is a giant elliptical galaxy, about ten times larger than the Milky Way, at the center of the Coma Galaxy Cluster. With its strong gravitational pull, it is able to hold onto more than 30,000 globular clusters of stars, more than any other galaxy that we know of, and even has a few dwarf galaxies in its grasp.

In this NASA/European Space Agency Hubble Space Telescope image, NGC 4874 is the brightest object, located to the right of the frame and seen as a bright star-like core surrounded by a hazy halo. A few of the other galaxies of the cluster are also visible, looking like flying saucers dancing around NGC 4874. However, the really remarkable feature of this image is the point-like objects around NGC 4874, revealed on a closer look—almost all of them are clusters of stars that belong to the galaxy. Each of these globular star clusters contains many hundreds of thousands of stars.

Recently, astronomers discovered that a few of these point-like objects are not star clusters but ultra-compact dwarf galaxies, also under the gravitational influence of NGC 4874. Being only about 200 light-years across and mostly made up of old stars, these galaxies resemble brighter and larger versions of globular clusters. They are thought to be the cores of small elliptical galaxies that, due to the violent interactions with other galaxies in the cluster, lost their gas and surrounding stars.

This Hubble image also shows many more distant galaxies that do not belong to the cluster, seen as small smudges in the background. While the galaxies in the Coma Cluster are located about 350 million light-years away, these other objects are much further out. Their light took several hundred million to billions of years to reach us.

Most unusually, the image also shows a very faint blue satellite trail, extending across the whole image, from the upper left corner of the frame to the lower right. Since Hubble’s cameras can only see a tiny part of the sky at one time, such trails are very rare.

This picture was created from optical and near-infrared exposures taken with the Wide Field Channel of Hubble’s Advanced Camera for Surveys. The field of view is 3.3 arcminutes across.

Aurora Borealis over Alaska

Aurora Borealis over Alaska

Astrophotographer Marybeth Kiczenski: "Wow! This was one of the best substorms I've ever seen! A glancing blow from a CME really made the Aurora come alive this morning in Alaska! What a way to end this trip to Fairbanks! The way the Aurora framed the Moon was just icing on the cake!"

Also known as the northern lights (aurora borealis) or southern lights (aurora australis), auroras are colorful, dynamic, and often visually delicate displays of an intricate dance of particles and magnetism between the Sun and Earth called space weather. When energetic particles from space collide with atoms and molecules in the atmosphere, they can cause the colorful glow that we call auroras.

Alaska is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is considered to be the northernmost, westernmost, and easternmost state in the United States. It borders the Canadian territory of the Yukon and the province of British Columbia to the east. It shares a western maritime border in the Bering Strait with Russia. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south.

Close-up: China CAS Space's New Commercial Kinetica-2 Rocket Launch

Close-up: China CAS Space's New Commercial Kinetica-2 Rocket Launch

🚀Announcing the success of a China CAS Space Kinetica-2 rocket on its first flight. A 53-meter-tall Kinetica-2 Y1 rocket launched on March 30, 2026, from the Dongfeng Commercial Space Innovation Pilot Zone in Northwest China. It has delivered three satellites into space—the New March 01 Technology Demonstration Satellite, the New March 02 Satellite, and TS 01 Educational Satellite into their designated orbits.

Developed by Chinese commercial space firm CAS Space, Kinetica-2 is China's first to adopt a Common Booster Core (CBC) configuration. The Kinetica-2 is a medium-lift, liquid-fuel rocket and the second launch vehicle developed by CAS Space, following the Kinetica-1. It is the company's first liquid-propellant rocket, and is tasked with supporting China's large-scale satellite deployment and low-cost cargo transportation for the Chinese space station.

The rocket consists of a multi-stage core booster that has a diameter of 3.35 meters, and two side boosters that also are 3.35 m wide. Its liftoff weight is 625 metric tons with a maximum thrust of 753 tons. The rocket is able to transport spacecraft with a combined weight of 8 tons to a typical sun-synchronous orbit at an altitude of 500 kilometers or 12 tons to a low-Earth orbit 200 km.

The New March 02 satellite, also known as the Qingzhou prototype test spacecraft, that launched today, adopts a single-module integrated configuration, allowing it to flexibly adapt to a variety of launch vehicles via its wide launch compatibility. It weighs only 4.2 metric tons.

CAS Space is a commercial spaceflight company established by the Institute of Mechanics under the Chinese Academy of Sciences.

China CAS Space's New Commercial Kinetica-2 Rocket Launch of Three Satellites

China CAS Space's New Commercial Kinetica-2 Rocket Launch of Three Satellites








🚀Announcing the success of a China CAS Space Kinetica-2 rocket on its first flight. A 53-meter-tall Kinetica-2 Y1 rocket launched on March 30, 2026, from the Dongfeng Commercial Space Innovation Pilot Zone in Northwest China. It has delivered three satellites into space—the New March 01 Technology Demonstration Satellite, the New March 02 Satellite, and TS 01 Educational Satellite into their designated orbits.

Developed by Chinese commercial space firm CAS Space, Kinetica-2 is China's first to adopt a Common Booster Core (CBC) configuration. The Kinetica-2 is a medium-lift, liquid-fuel rocket and the second launch vehicle developed by CAS Space, following the Kinetica-1. It is the company's first liquid-propellant rocket, and is tasked with supporting China's large-scale satellite deployment and low-cost cargo transportation for the Chinese space station.

The rocket consists of a multi-stage core booster that has a diameter of 3.35 meters, and two side boosters that also are 3.35 m wide. Its liftoff weight is 625 metric tons with a maximum thrust of 753 tons. The rocket is able to transport spacecraft with a combined weight of 8 tons to a typical sun-synchronous orbit at an altitude of 500 kilometers or 12 tons to a low-Earth orbit 200 km.

The New March 02 satellite, also known as the Qingzhou prototype test spacecraft, that launched today, adopts a single-module integrated configuration, allowing it to flexibly adapt to a variety of launch vehicles via its wide launch compatibility. It weighs only 4.2 metric tons.

CAS Space is a commercial spaceflight company established by the Institute of Mechanics under the Chinese Academy of Sciences.
