The Bipolar Jets of KX Andromedae

 

Blasting outward from variable star KX Andromedae, these stunning bipolar jets are 19 light-years long. Recently discovered, they are revealed in unprecedented detail in this deep telescopic image centered on KX And and composed from over 692 hours of combined image data. In fact, KX And is spectroscopically found to be an interacting binary star system consisting of a bright, hot B-type star with a swollen cool giant star as its co-orbiting, close companion. The stellar material from the cool giant star is likely being transferred to the hot B-type star through an accretion disk, with spectacular symmetric jets driven outward perpendicular to the disk itself. The known distance to KX And of 2,500 light-years, angular size of the jets, and estimated inclination of the accretion disk lead to the size estimate for each jet of an astonishing 19 light-years.

A New Hubble Space Telescope Image of 3I/ATLAS

December 5, 2025

 

The interstellar visitor 3I/ATLAS was reobserved by the Hubble Space Telescope from a distance of 286 million kilometers on November 30, 2025, a month after its closest approach to the Sun (perihelion).

The image shows a teardrop-shaped glowing halo that extends towards the Sun.

This sunward anti-tail extension was also apparent in the pre-perihelion Hubble image of 3I/ATLAS, taken on July 21, 2025, as 3I/ATLAS was approaching the Sun from a distance that is 56% larger from Earth.

The new radius of the glow is about 40,000 kilometers and its anti-tail extension goes out to about 60,000 kilometers.

 

In a recent paper, accessible here, I suggested that the teardrop of the coma in post-perihelion images of 3I/ATLAS is associated with a large number of macroscopic non-volatile objects that separated from it as a result of its measured non-gravitational acceleration away from the Sun.

My paper predicted that by November 30th, the swarm of objects would be closer to the Sun than 3I/ATLAS by about 60,000 kilometers if the objects overlapped with 3I/ATLAS at perihelion.

This separation is in perfect agreement with the anti-tail extension of the teardrop shape in the new Hubble image.

 

We are awaiting the release of the full Hubble data set which includes ultraviolet spectroscopy to determine the composition of the gas plume around 3I/ATLAS.

In the meantime, amateur astronomers continue to provide magnificent large-scale images that extend out to millions of kilometers around 3I/ATLAS.

 

Addendum: The AI Nemesis of Scientific Information

Imagine creating videos that feature avatars of scientists that look like them and speak in their voice, but spread counterfactual information about 3I/ATLAS. How would the public know who to believe?

This is not a plot from a science fiction novel but the reality we face today.

Over the past two weeks, I received hundreds of emails from fans who noticed a YouTube channel named after me, accessible here, with fake videos about the interstellar object 3I/ATLAS, created by artificial intelligence (AI), that spread false content that contradicts my written essays on https://avi-loeb.medium.com/

 

It was obvious to my fans that the videos were fake because the clock in the background was frozen on a specific time and because two weeks ago — I injured my face on a trip to a podcast interview in Florida — whereas the fake videos did not show any sign of the injury.

Nevertheless, a news outlet included one of these videos in a report about my research on 3I/ATLAS, blending reality with fake content when reporting about science.

 

In using AI to generate fake videos impersonating me, this YouTube channel violates several aspects of YouTube’s community guidelines and Terms of Service which should be the basis for YouTube to remove the channel.

I hold the entity that created the fake videos legally liable to defamation and false content. By now, my fans and I filed dozens of reports to YouTube but the company did not take responsibility to fix this matter.

 

We are living in a new reality where fake content can be easily generated by AI. This raises a serious problem of how to authenticate the validity of information on the internet. Science focuses on figuring out the physical reality based on facts.

The nemesis of science is fake content created by AI. For our civilization to prosper and advance scientifically, we must develop tools that distinguish fact-based scientific content from hallucinated content spread by AI avatars.

Jared Isaacman

@rookisaacman

 

Thank you, Mr. President @POTUS, for this opportunity. It will be an honor to serve my country under your leadership.

 

I am also very grateful to @SecDuffy, who skillfully oversees @NASA alongside his many other responsibilities.

 

The support from the space-loving community has been overwhelming. I am not sure how I earned the trust of so many, but I will do everything I can to live up to those expectations.

 

To the innovators building the orbital economy, to the scientists pursuing breakthrough discoveries and to dreamers across the world eager for a return to the Moon and the grand journey beyondthese are the most exciting times since the dawn of the space age and I truly believe the future we have all been waiting for will soon become reality.

 

And to the best and brightest at NASA, and to all the commercial and international partners, we have an extraordinary responsibility–but the clock is running.

 

The journey is never easy, but it is time to inspire the world once again to achieve the near-impossible–to undertake and accomplish big, bold endeavors in space…and when we do, we will make life better here at home and challenge the next generation to go even further.

 

NASA will never be a caretaker of history–but will forever make history.

 

Godspeed, President Donald J. Trump, and Godspeed NASA, as America leads the greatest adventure in human history 🇺🇸

International Space Station prepares for new commander, heads into final five years of planned operations

December 5, 2025

 

After 25 years of continuous human presence, the International Space Station is heading into its final half decade of planned habitation.

NASA and its international partners are planning to intentionally deorbit the orbiting laboratory around 2030 or shortly thereafter.

SpaceX was contracted valued at up to $843 million to build the United States Deorbit Vehicle (USDV), which will help guide the space station towards a splashdown in an uninhabited portion of the Pacific Ocean.

 

On Sunday, Dec. 7 NASA astronaut Mike Fincke will assume the role of ISS Commander, taking over from Russian cosmonaut Sergey Ryzhikov.

The cosmonaut along with his colleague, Alexey Zubritsky and NASA astronaut Jonny Kim, will then board their Soyuz spacecraft and undock Monday evening to complete their 245-day mission in orbit.

With funding from the recent budget bill from Congress and renewed promise from NASA Administrator nominee Jared Isaacman to “maximize the scientific value of every dollar that Congress affords the agency,” the space station will continue to be a bustling hub of science for its final five years.

 

On Thursday, the Center for the Advancement of Science in Space (CASIS) announced an extension of its cooperative agreement with NASA to allow the non-profit to continue managing the ISS National Laboratory through 2030.

This allows CASIS, through the ISS National Lab, to continue managing up to 50 percent of the flight allocation on cargo missions and up to 50 percent of U.S. Operating Crew time for science backed by them.

The ISS National Lab backed more than 940 payloads launched to the space station during the period of CASIS management, which began in 2011.

 

“For nearly 14 years, NASA has entrusted CASIS with managing this incredible asset for our nation and for the benefit of humanity,” said Ramon (Ray) Lugo, principal investigator and chief executive officer of CASIS.

“We are honored that NASA has extended this unique partnership through 2030, and we will continue to work in collaboration, pushing the limits of space-based R&D for the benefit of life on Earth while driving a robust and sustainable market economy in space.”

 

Going to and fro

While the science planned for the ISS is in no short supply, the methods of getting it and its inhabitants to and from the space station is a trickier matter.

The most recent wrinkle came in the wake of the Soyuz MS-28 launch. After NASA astronaut Chris Williams along with Russian cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev, the mobile service platform, which allows technicians access to the engine section of the rocket prior to launch, collapsed into the flame duct at Site 31.

 

According to Russia-based journalist, Anatoly Zak, there are varying estimates of how long repairs could take, with at least one source telling him that it could take “up to two years” and that the immediate path forward wasn’t clear.

In a statement published to its official Telegram account, Roscosmos said that the damaged would be fixed “in the nearest time,” but didn’t provide details. Spaceflight Now reached out to the Russian space agency for comment and is waiting to hear back.

For its part, NASA mostly diverted questions to Roscosmos. Russia’s Progress cargo spacecraft not only deliver supplies but also propellants for the Russian-side of the complex, used to maintain the station’s orbital altitude and also to assist with attitude control.

Some reboost functions are being performed by a SpaceX Cargo Dragon vehicle outfitted with a special boost kit in its unpressurized trunk.

A NASA spokesperson said that this Dragon, launched to the ISS on the Commercial Resupply Services 33 (CRS-33) mission “will undock in late January 2026, before splashing down and returning critical science and hardware to teams on Earth.”

“Station has sufficient capability for reboost and attitude control, and there are no expected impacts to this capability,” a spokesperson said on Thursday.

As for crew capabilities, it’s unclear how much the Site 31 pad damage will delay the launch of the Soyuz MS-29 mission, if at all.

 

A July 2025 press release from NASA announcing its astronaut, Anil Menon, as a crew member stated that the Soyuz MS-29 mission would launch in June 2026.

However, on Thursday, aspokesperson for the agency said the mission “has always been scheduled to launch in July 2026.

As for U.S. crewed missions, the SpaceX Crew-12 mission is the next up to bat after NASA confirmed that the next flight of a Boeing CST-100 Starliner spacecraft (Starliner-1) would be a cargo-only mission.

Starliner may carry crew on its next voyage, but that depends on the outcome of the Starliner-1 mission.

 

Sketching the future

In these final five years, NASA and its partners will begin winding down station operations and in the immediate years before its demise, the station will be slowly lowered using orbital drag and the station’s thrusters over the course of two to two-and-a-half years, according to Dana Weigel, ISS Program Manager, during a post-launch Crew-11 briefing.

“The Russian segment is prime for doing all of that. So, all of the attitude control, debris avoidance, anything we do with actively lowering is from the Russian segment,” Weigel said.

 

“Once we get down to the point of actually deorbiting, our current plan is to have the Russian segment do attitude control and the USDV do actual thrusting and boost,” she added.

“That gives us additional layers of redundancy, so that if something happened with the attitude control, you can then switch over to the USDV. So, it’s very much an integrated plan and an integrated solution.”

One way that delays to future Progress vehicle launches may impact the station is also in stocking up on fuel for those future lowering burns as well as attitude control.

 

“Part of what Roscosmos is working on right now is fuel delivery. So, we’ve got to get the fuel reserves on station to the point where they can do their portions of this,” Weigel said in early August.

“Latest predictions are that will probably be at the right level in early 2028 and we’ll probably start drifting down in mid-2028. We’ve got to make sure we have the fuel there and everyone’s ready to go. And then the USDV will arrive mid-2029.”

 

As for the crews onboard, assuming the current schedule holds, the final years onboard station may look something like the following:

Feb. 2026 – SpaceX Crew-12

July 2026 – Soyuz MS-29

Oct. 2026 – SpaceX Crew-13 or Starliner-2

March 2027 – Soyuz MS-30

June 2027 – Dragon or Starliner

Nov. 2027 – Soyuz MS-31

Feb. 2028 – Dragon or Starliner

July 2028 – Soyuz MS-32

Oct. 2028 – Dragon or Starliner

March 2029 – Soyuz MS-33

June 2029 – Dragon or Starliner

Nov. 2029 – Soyuz MS-34

Feb. 2030 – Dragon or Starliner

 

Asked whether NASA would want its final crew onboard station to be comprised of seasoned veterans instead of making sure its newest astronauts get flight experience Weigel told Spaceflight Now following the Crew-11 briefing that it’s a complicated question.

“I think there are so many different factors that can work on that. One of the things from a medical consideration standpoint is we do limit radiation exposure for crew members and if we’re asking for a year-long mission, we have to factor all of that in for crew health,” Weigel said.

“So, in an ideal sense, you’d say, ‘Yeah, send me somebody who’s flown, who’s great at spacewalks, this, that and the other.’ But too much experience puts you over the radiation limit.”
