A team of astronomers has taken the sharpest-ever picture of the unexpected interstellar comet 3I/ATLAS, using the crisp vision of the NASA/ESA Hubble Space Telescope.
ESA's Planetary Defence Office responded promptly to the discovery of the comet, and has been tracking it since the beginning of July.
Now, Hubble's observations from space are allowing astronomers to more accurately estimate the size of the comet’s solid icy nucleus. The upper limit on the diameter of the nucleus is 5.6 km, but it could be as small as 320 m across, researchers report.
Though the Hubble images put tighter constraints on the nucleus size compared to previous ground-based estimates, the solid heart of the comet presently cannot be directly seen, even by Hubble. Further observations, including by the NASA/ESA/CSA James Webb Space Telescope, will help refine our knowledge about the comet, including its chemical makeup.
Hubble also captured a dust plume ejected from the Sun-warmed side of the comet, and the hint of a dust tail streaming away from the nucleus. Hubble’s data show that the comet is losing dust in a similar manner to that from previously seen Sun-bound comets originating within our Solar System.
The big difference is that this interstellar visitor originated in some other stellar systems, elsewhere in our Milky Way galaxy.
3I/ATLAS is traveling through our Solar System at roughly 210 000 km per hour, the highest speed ever recorded for a Solar System visitor. This breathtaking sprint is evidence that the comet has been drifting through interstellar space for many billions of years. The gravitational slingshot effect from innumerable stars and nebulae the comet passed added momentum, ratcheting up its speed. The longer 3I/ATLAS was out in space, the higher its speed grew.
This comet was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) on 1 July 2025 at a distance of 675 million km from the Sun. 3I/ATLAS should remain visible to ground-based telescopes until September, after which it will pass too close to the Sun to observe. It is expected to reappear on the other side of the Sun by early December.
Icy wanderers such as 3I/ATLAS offer a rare, tangible connection to the broader galaxy. To actually visit one would connect humankind with the Universe on a far greater scale. To this end, ESA is preparing the Comet Interceptor mission. The spacecraft will be launched in 2029 into a parking orbit, lying in wait for a suitable target – a pristine comet from the distant Oort Cloud that surrounds our Solar System, or, unlikely but highly appealing, an interstellar object.
While it is improbable that we will discover an interstellar object that is reachable for Comet Interceptor, as a first demonstration of a rapid response mission that waits in space for its target, it will be a pathfinder for possible future missions to intercept these mysterious visitors.
The research paper based on Hubble observations will be published in The Astrophysical Journal Letters.
[Image description: At the center of the image is a comet that appears as a teardrop-shaped bluish cocoon of dust coming off the comet’s solid, icy nucleus and seen against a black background. The comet appears to be heading to the bottom left corner of the image. About a dozen short, light blue diagonal streaks are seen scattered across the image, which are from background stars that appeared to move during the exposure because the telescope was tracking the moving comet.]

Using the long black rotor blades works well I think. They are 2 studs wide so I needed to extend the entire wing structure out to the same 2-studs width, making the design feature more substantial.

I'll bet you didn't know that inside of Seattle Aquarium interstellar travel is possible. What do you suppose lies beyond the purplish horizon and yellow stars. Do you hear something?
Here is my Get Pushed! challenge from HarryJ. Check out his stream, he's really good with light and has a great sense of humor.
"I'm going to give you two challenges, select just one of them
Photograph an item/thing, not a person, that is partially lit by the light coming from a street lamp. The light should not be "full frontal"
The second one is to take a formal portrait. It does not need to be indoors but it should not be a candid. I hope that the image you post will be one chosen from a number of images of the same person. Oh, and not a family member."
Well, to be brief, #2 was not an option for me. So I went for #1.
In my mind #1 was going to be kind of dark alley-ish, very shadowy, a shaft of light. But I just couldn't create that with the sodium vapor lamps around my part of town which just give out a wash of yellow light.
So to try to get to the point... the photo above is illuminated by the street lamp. That is the glare you see coming from the bottom left corner. The exposure is a long exposure and so it looks as if the tree is illuminated a la "full frontal", but it actually isn't. Believe it or not, the lamp is pointed down and away from the tree. And so, that's it. Thanks for the push HarryJ. It was very challenging for me. I came up with something I totally wasn't expecting, and which barely meets the challenge, but I guess it passes.

A build with the title: Strangers in a strange land. The spaceship IEV Sunshine is a Interstellar Exploration Vessel that travels in space looking for planets with sentient lifeforms and new plants that could be used for medicines. Vi is the captain and Yor is her husband that also is the ship’s mechanic. The two scientists Lema and Mari have a robot called Gjor that helps them when they search the planets. The last crew member is the pilot Tor, today it's his birthday and Mari is preparing a birthday "fika" (feast). They landed a short distance away but as the captain Vi, Lema and Gjor moved in the terrain they decided to land closer so they all could celebrate Tor together. All while Yor is traversing the wing to find a small problem with the solar panels. Now they are flying in to land on this new planet again, closer to the explorers. We hope they all have a nice fika and a successful mission!
That's the story I developed during building this. As almost always I have a "hidden" or deeper meaning in my builds or something in the builds that connects to things in my life. Sci-fi was my first book crush and I still love to read sci-fi as well as fantasy. Those of you who have read about my other builds know that I live with chronic pain and have had a really hard time the last couple of years. It's getting a little bit better but how do you go from surviving life to starting to living it? Me and my husband are strangers to this new strange land of things you do when you really live. To enjoy family and friends more, travel and experience new things. Learn new skills and have more energy to "unnecessary" things. It's exciting and at the same time scary. It's hard mental work to be more open and to believe that things will work out. These thoughts have coloured my process when building it. I wanted it to be joyful but the ship didn't turn out that way in my meaning. That slowed down my building and I had to wrap my mind around that the vessel to this strange land carried all my emotions and baggage and is more austere as a result. But the landscape is all my joy, all the things we want to experience for so many more years together.

THE INTERSTELLAR PASSAGE
You're probably wondering how he can go back and forth between these two worlds as well?
Good question.
If I had to compare to simplify the thing: it's a bit similar to the Stargate, a kind of cosmic airlock between two worlds, invisible, imperceptible.
I do not really realize when it happens.
Sometimes an animal follows me without I realize it.
And when this happens, it happens then one of the most amazing things that we are the possibility of seeing in its life: the Zorgonaut transmutation, or how a Zorg animal arriving on your planet is undergoing mutagenic combination in another animal, its DNA is combined by the interstellar passage in else that would be your equivalent of an imaginary animal. For Zorgonauts there's no doubt that these are the animals that have combined Zorg via the passage. Today your lack of imagination makes you believe that mermaids, griffins dragons centaurs minotaurs etc ... are merely fabrications, and you bring to believe in evolution according to Darwin.
So my last visit and my last return through the "door", a Cobrafe followed me and the passage was born a GIRABRA
LE PASSAGE INTERSIDERAL
Vous vous demandez certainement comment peut il aller et venir entre ces 2 mondes ainsi ?
Bonne question.
Si je devais comparer pour vous simplifier la chose : c’est un peu comparable à la porte des étoiles, une sorte de sas cosmique entre les 2 univers, invisible, imperceptible.
Je ne me rends vraiment pas compte quand cela se produit.
Quelques fois un animal me suit sans que je ne m’en rende compte.
Et quand cela se produit il se passe alors une des choses les plus incroyables que l’on est la possibilité de voir dans sa vie : la transmutation Zorgonautienne, ou comment un animal de Zorg en arrivant sur votre planète se voit subir une combinaison mutagène en un autre animal, son ADN se combine de par le passage intersidéral en autre chose qui serait pour vous l’équivalent d’un animal imaginaire. Pour les Zorgonautes cela ne fait aucun doute que ce sont des animaux de Zorg qui se sont combinés en empruntant le passage . Aujourd hui votre manque d’imagination vous fait croire que les sirènes, les dragons les griffons les centaures les minotaures etc… ne sont qu’ affabulations , et vous a amenez à croire en l’ évolution selon Darwin.
Ainsi ma dernière visite et mon dernier retour par « la porte », un Cobrafe m’a suivi et le passage a vu naître un GIRABRA

Scientists using NASA’s Hubble Space Telescope have confirmed the presence of electrically-charged molecules in space shaped like soccer balls, shedding light on the mysterious contents of the interstellar medium (ISM) – the gas and dust that fills interstellar space.
Since stars and planets form from collapsing clouds of gas and dust in space, “The diffuse ISM can be considered as the starting point for the chemical processes that ultimately give rise to planets and life,” said Martin Cordiner of the Catholic University of America, Washington. “So fully identifying its contents provides information on the ingredients available to create stars and planets.” Cordiner, who is stationed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is lead author of a paper on this research published April 22nd in the Astrophysical Journal Letters.
The molecules identified by Cordiner and his team are a form of carbon called “Buckminsterfullerene,” also known as “Buckyballs,” which consists of 60 carbon atoms (C60) arranged in a hollow sphere. C60 has been found in some rare cases on Earth in rocks and minerals, and can also turn up in high-temperature combustion soot.
C60 has been seen in space before. However, this is the first time an electrically charged (ionized) version has been confirmed to be present in the diffuse ISM. The C60 gets ionized when ultraviolet light from stars tears off an electron from the molecule, giving the C60 a positive charge (C60+). “The diffuse ISM was historically considered too harsh and tenuous an environment for appreciable abundances of large molecules to occur,” said Cordiner. “Prior to the detection of C60, the largest known molecules in space were only 12 atoms in size. Our confirmation of C60+ shows just how complex astrochemistry can get, even in the lowest density, most strongly ultraviolet-irradiated environments in the Galaxy.”
Life as we know it is based on carbon-bearing molecules, and this discovery shows complex carbon molecules can form and survive in the harsh environment of interstellar space. “In some ways, life can be thought of as the ultimate in chemical complexity,” said Cordiner. “The presence of C60 unequivocally demonstrates a high level of chemical complexity intrinsic to space environments, and points toward a strong likelihood for other extremely complex, carbon-bearing molecules arising spontaneously in space.”
Most of the ISM is hydrogen and helium, but it’s spiked with many compounds that haven’t been identified. Since interstellar space is so remote, scientists study how it affects the light from distant stars to identify its contents. As starlight passes through space, elements and compounds in the ISM absorb and block certain colors (wavelengths) of the light. When scientists analyze starlight by separating it into its component colors (spectrum), the colors that have been absorbed appear dim or are absent. Each element or compound has a unique absorption pattern that acts as a fingerprint allowing it to be identified. However, some absorption patterns from the ISM cover a broader range of colors, which appear different from any known atom or molecule on Earth. These absorption patterns are called Diffuse Interstellar Bands (DIBs). Their identity has remained a mystery ever since they were discovered by Mary Lea Heger, who published observations of the first two DIBs in 1922.
A DIB can be assigned by finding a precise match with the absorption fingerprint of a substance in the laboratory. However, there are millions of different molecular structures to try, so it would take many lifetimes to test them all.
“Today, more than 400 DIBs are known, but (apart from the few newly attributed to C60+), none has been conclusively identified,” said Cordiner. “Together, the appearance of the DIBs indicate the presence of a large amount of carbon-rich molecules in space, some of which may eventually participate in the chemistry that gives rise to life. However, the composition and characteristics of this material will remain unknown until the remaining DIBs are assigned.”
Decades of laboratory studies have failed to find a precise match with any DIBs until the work on C60+. In the new work, the team was able to match the absorption pattern seen from C60+ in the laboratory to that from Hubble observations of the ISM, confirming the recently claimed assignment by a team from University of Basel, Switzerland, whose laboratory studies provided the required C60+ comparison data. The big problem for detecting C60+ using conventional, ground-based telescopes, is that atmospheric water vapor blocks the view of the C60+ absorption pattern. However, orbiting above most of the atmosphere in space, the Hubble telescope has a clear, unobstructed view. Nevertheless, they still had to push Hubble far beyond its usual sensitivity limits to stand a chance of detecting the faint fingerprints of C60+.
The observed stars were all blue supergiants, located in the plane of our Galaxy, the Milky Way. The Milky Way's interstellar material is primarily located in a relatively flat disk, so lines of sight to stars in the Galactic plane traverse the greatest quantities of interstellar matter, and therefore show the strongest absorption features due to interstellar molecules.
The detection of C60+ in the diffuse ISM supports the team’s expectations that very large, carbon-bearing molecules are likely candidates to explain many of the remaining, unidentified DIBs. This suggests that future laboratory efforts measure the absorption patterns of compounds related to C60+, to help identify some of the remaining DIBs.
The team is seeking to detect C60+ in more environments to see just how widespread buckyballs are in the Universe. According to Cordiner, based on their observations so far, it seems that C60+ is very widespread in the Galaxy.
