Comet C/2025 A6 (Lemmon): A New View from Arizona

Comet C/2025 A6 (Lemmon): A New View from Arizona


Congratulations to astrophotographer Larry Hubble for sharing this spectacular high-resolution image of Comet C/2025 A6 (Lemmon) taken near Sedona, Arizona. By the way, Hubble is Larry's birth name and what a great one it is! Please thank Larry in the comments for submitting his image to Friends of NASA for you all to enjoy!

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.

Comet C/2025 A6 Lemmon | International Space Station

Comet C/2025 A6 Lemmon | International Space Station





Expedition 73 flight engineer and Japan Aerospace Exploration Agency (JAXA) astronaut Kimiya Yui: "Good morning, everyone! I'm sorry for talking about comets so much lately, but today's scenery was also spectacular, so please allow me to introduce it.  

It was dancing so gorgeously through the pre-dawn universe that it was too magnificent to call Lemon-chan, so today I'll refer to it as Lemon-san lol.  

It was just like a mermaid swimming through a sea of auroras.

After a busy day comes to an end, I've been continuing to take photos to soothe my fatigue. Lately, my source of healing has been Lemon-chan, I suppose? lol."

Japan's HTV-X1 Cargo Spacecraft Rocket Launch | International Space Station

Japan's HTV-X1 Cargo Spacecraft Rocket Launch | International Space Station

🚀 The Japan Aerospace Exploration Agency (JAXA) launched its HTV-X1 cargo spacecraft on a H3-24L rocket to the International Space Station (ISS) from the Yoshinobu Launch Complex at Tanegashima Space Center in southeastern Japan on Sunday, October 26, 2025. The launch had been delayed due to poor weather.

The H3-24L expendable rocket was developed by JAXA and Mitsubishi Heavy Industries (MHI) as a successor to the H-IIA and H-IIB rockets.

The HTV-X1, also built by MHI for JAXA, is an uncrewed, expendable spacecraft designed to resupply the ISS, while serving as a platform for technical demonstrations. Japan developed the HTV-X spacecraft as a replacement for the earlier HTV (Kounotori) cargo ship that launched atop the now-retired H-IIB.

The H3 is a medium-lift launch vehicle. Its first stage utilizes two or three LE-9 engines and uses 222 tons of liquid hydrogen (LH2) and liquid oxygen (LOX), otherwise known as hydrolox. The second stage uses one LE-5B-3 engine and is powered by 23 tons of hydrolox.

There is the additional capability of strap-on solid rocket boosters (SRBs); the H3 rocket can have two or four SRB-3s.

Unlike its predecessor that required eighty hours for cargo loading, the HTV-X1 reduces the process to just 24 hours, helping to improve mission efficiency.

With a launch mass of 16,000 kg, the HTV-X1 can carry up to 5,820 kg of supplies and experiments using International Standard Payload Racks to increase capacity. The spacecraft has two solar panel arrays generating 1 kW of power—five times the 200 W capacity of the original HTV.

Onboard power supplies and refrigeration units allow the delivery of fresh food to Expedition 73 and future ISS crews. The HTV-X1 maneuvers using its reaction control system (RCS) thrusters.

JAXA astronaut Kimiya Yui, a crew member of Expedition 73, will dock the HTV-X1 to the ISS’s Harmony module using the Canadarm2, a robotic arm developed by the Canadian Space Agency. Yui previously berthed an HTV spacecraft during Expedition 44 in 2015. Once attached, the HTV-X1 is expected to remain at the ISS for six months. After departing, it has the capability for extended missions, enabling additional scientific and technical experiments.

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.

Shenzhou-21 Crewed Rocket Moved to Launchpad | China Space Station

Shenzhou-21 Crewed Rocket Moved to Launchpad | China Space Station








🚀 The Shenzhou-21 crewed mission to the China Space Station is preparing for launch!

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




Elon Musk has commented on the Landspace Zhuque-3's design: "They have added aspects of Starship, such as use of stainless steel and methalox, to a Falcon 9 architecture, which would enable it to beat Falcon 9 . . ."

Zhuque-3 use of liquid methane and liquid oxygen as propellants is called methalox propulsion.

The SpaceX Falcon 9 uses an aluminum alloy and carbon fiber for its first stage fairing, along with liquid oxygen (LOX) and RP-1, a refined kerosene, as fuel.

Preparation for the maiden flight of China's reusable rocket Zhuque-3 has entered a critical phase after the completion of joint fueling drills and static ignition tests from October 18 to 20, 2025. The successful tests also laid the groundwork for the rocket's official launch and first-stage recovery later this year.

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

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.

Journey to Wolf-Rayet Star VFTS 682 in Nearby Large Magellanic Cloud Galaxy

Journey to Wolf-Rayet Star VFTS 682 in Nearby Large Magellanic Cloud Galaxy


This sequence starts with a view of the Milky Way galaxy and its two small neighboring galaxies, the Magellanic Clouds. We zoom in towards the Large Magellanic Cloud and focus on the huge star formation region around the Tarantula Nebula. The final sequence shows a very detailed view, captured in visible and infrared light, of the dense star cluster R 136 and the very brilliant, but strangely isolated, star VFTS 682. All Wolf–Rayet stars are highly luminous objects due to their high temperatures—thousands of times the luminosity of our Sun.

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.
