Comet C/2025 A6 (Lemmon): View from Arizona
Comet C/2025 A6 (Lemmon): View from Arizona
Astrophotographer Jeremy Perez: "C/2025 A6 (Lemmon) from last night. It is a really good telescopic target right now! Lots more detail throughout the tail but especially close to the coma with streamers fanning out inside the dust tail. It was interesting to see the turquoise coma breezing off to the right a bit too. Not sure if I've picked up on something like that before & why it would have an even steeper angle than the dust tail. Or could be a bit of an illusion with the other side of the dust tail kind of hiding what may be on the other side . . ."
Comet Lemmon is brightening and moving into morning northern skies. Besides Comet SWAN25B and Comet ATLAS, Comet C/2025 A6 (Lemmon) is now the third comet currently visible with binoculars and on long camera exposures. Comet Lemmon was discovered early this year and is still headed into the inner Solar System. The comet will round the Sun on November 8, 2025. It passed nearest to the Earth—about half of the Earth-Sun distance—on October 21.
Arizona is a landlocked state in the Southwestern region of the United States, sharing the Four Corners region of the western United States with Colorado, New Mexico, and Utah. It also borders Nevada to the northwest and California to the west, and shares an international border with the Mexican states of Sonora and Baja California to the south and southwest.

Shenzhou-21 Crewed Rocket Moved to Launchpad | China Space Station
Shenzhou-21 Crewed Rocket Moved to Launchpad | China Space Station
The combination of the Shenzhou-21 crew spacecraft and its Long March-2F carrier rocket was transferred to the launch area of the Jiuquan Satellite Launch Center in northwest China on the morning of October 24, 2025, as the country prepares to send another crew to its orbiting space station. Final checks and preparations begin ahead of its journey to the China Space Station. It is expected that the crew will be announced on Oct. 31 with the launch the following day, Nov. 1.
Carried by a mobile launch platform, the combination moved along 1.5 km of seamless rail toward the launch tower from the testing facility.
"This rocket incorporates 16 design changes, with the most important one being the fully upgraded optical navigation system, which greatly improves the redundant inertial measurement units and boost flight reliability," said Sun Yanqiu, an engineer of the China Aerospace Science and Technology Corp.
The Shenzhou-21 will be the 10th crewed mission since China began the initial construction of its space station and the sixth one since the space station entered the stage of application and development.
"After today's transfer, we will conduct checks on the combination's functions as well as a full-system launch rehearsal and an integrated rehearsal to verify compatibility between system interfaces, coordination and procedures. Once everything is confirmed normal, we will carry out rocket propellant filling and proceed to ignition and launch," said Zhao Lei, an engineer at the Jiuquan Satellite Launch Center.
According to schedule, the Shenzhou-21 crewed spacecraft is set to be launched at an appropriate time in the coming days.
The Shenzhou-21 crew will replace the astronauts of the Shenzhou-20 mission that have worked in orbit for six months.

China Landspace Reusable Zhuque-3 Commercial Rocket: Launchpad Views
China Landspace Reusable Zhuque-3 Commercial Rocket: Launchpad Views
With a diameter of 4.5 meters and a total length of around 66 meters, the Zhuque-3 rocket can carry up to 18 satellites per launch, making it an ideal choice for launching satellites for large-scale constellation networks.
Equipped with landing legs and grid fins for controlled descent, the rocket is designed to vertically recover its most expensive component—the first stage, accounting for 70 percent of the rocket's total cost.
As its first stage is designed to be reused at least 20 times, the rocket has the potential to reduce launch costs by 80 to 90 percent compared with single-use rockets.
Powered by a parallel cluster of nine liquid oxygen-methane engines, the first-stage can achieve meter-level landing precision, as five of the engines are capable of gimballing.
In addition, these engines produce a combined thrust of more than 7,500 kilonewtons, setting a new record for Chinese commercial liquid-fueled rockets.
Beijing-based LandSpace is a leading Chinese private space company. With its Zhuque-2 rocket, LandSpace became the world's first company to launch a methane-liquid oxygen rocket to Earth orbit in July 2023, ahead of U.S. rivals, including Elon Musk's SpaceX and Jeff Bezos' Blue Origin.
The successful Zhuque-3 development marks a significant stride in the pursuit of low-cost, high-frequency, and large-capacity space launches for China's private space industry.
The Jiuquan Satellite Launch Center (JSLC) in nortwestern China was founded in 1958. It was the first of China's four spaceports. The launch center has been the focus of many of China's historic space ventures, including the country's first satellite Dong Fang Hong I in 1970 and their first crewed space mission, Shenzhou V, on October 15, 2003. JSLC is now a home for many new Chinese commercial space launch firms, like Landspace.

Flight Through The Orion Nebula in Visible Light | Space Telescope Science Institute
This visualization explores the Orion Nebula as seen in visible-light observations from the Hubble Space Telescope.
As the camera flies into the star-forming region, it reveals a glowing gaseous landscape that has been illuminated and carved by the high-energy radiation and strong stellar winds from the massive hot stars in the central cluster. The high-resolution visible observations show fine details including the wispy bow shocks and tadpole-shaped proplyds.
The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula in the Milky Way situated south of Orion's Belt in the constellation of Orion. It is known as the middle "star" in the "sword" of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky with an apparent magnitude of 4.0. The Orion Nebula is the closest region of massive star formation to Earth. M42 is estimated to be 25 light-years across (so its apparent size from Earth is approximately 1 degree). It has a mass of about 2,000 times that of the Sun.

Wolf-Rayet Star VFTS 682 in Nearby Large Magellanic Cloud Galaxy | ESO
This view shows part of the very active star-forming region around the Tarantula Nebula in the Large Magellanic Cloud, a small neighbor of the Milky Way galaxy. At the exact center lies the brilliant, but isolated star, VFTS 682, and to its lower right the very rich star cluster R 136. The origins of VFTS 682 are unclear—was it ejected from R 136 or did it form on its own? The star appears yellow-red in this view that includes visible-light and infrared images from the Wide Field Imager at the 2.2-meter MPG/ESO Telescope at the La Silla Observatory and the 4.1-meter infrared VISTA telescope at the Paranal Observatory, because of the effects of dust.

Wolf-Rayet Star WR 31a & Nebula in Carina | Hubble Space Telescope
Wolf-Rayet Star WR 31a & Nebula in Carina | Hubble Space Telescope
WR 31a, commonly referred to as Hen 3-519, is a Wolf–Rayet (WR) star in the southern constellation of Carina. It is surrounded by an expanding Wolf–Rayet nebula—a shell of ionized gas nearly eight light-years wide. It is not a classical old stripped-envelope WR star, but a young massive star that still has significant hydrogen left in its atmosphere. All Wolf–Rayet stars are highly luminous objects due to their high temperatures—thousands of times the luminosity of our Sun.
Distance from Earth: about 31,000 light years
WR 31a is surrounded by a blue bubble nebula created by a powerful stellar wind impacting material expelled during earlier stages of the star's life. This nebula was found by Yale University astronomer, Ellen Dorrit Hoffleit (1907-2007), in 1953.

The Crab Nebula: Multiwavelength Structure of a Pulsar Wind Nebula | STScI
The Crab Nebula: Multiwavelength Structure of a Pulsar Wind Nebula | STScI
This visualization features a three-dimensional multiwavelength representation of the Crab Nebula, a pulsar wind nebula that is the remains of an exploded star. The video is based on images from NASA’s three Great Observatories: the Chandra X-ray Observatory and the Hubble and Spitzer Space Telescopes.
The video begins by showing the Crab Nebula in context, pinpointing the location of the observed supernova in the constellation Taurus. This view zooms in to present the Hubble, Spitzer, and Chandra images of the Crab Nebula, each highlighting one of the nested structures in the system.
The video then begins a slow buildup of the three-dimensional X-ray structure, showing the pulsar and disk of energized material, and adding jets of particles firing off from opposite sides of the energetic dynamo.
Appearing next is a rotating infrared view of a glowing cloud of emission, called synchrotron radiation, enveloping the pulsar system. This distinctive form of radiation occurs when streams of charged particles spiral around the pulsar’s magnetic field lines.
The visible-light outer shell of the Crab Nebula appears next. Looking like a cage around the entire system, this shell of glowing gas consists of tentacle-shaped filaments of ionized oxygen. The tsunami of particles unleashed by the pulsar is pushing on this expanding debris cloud like an animal rattling its cage.
The x-ray, infrared, and visible-light models are combined at the end of the video to reveal both a rotating three-dimensional multiwavelength view and the corresponding two-dimensional multiwavelength image of the Crab Nebula.
