Today, a magnificent large-scale image of the interstellar object 3I/ATLAS, was reported here by Frank Niebling and Michael Buchner. The stacked image combines a series of 5 exposures, each lasting 3 minutes, from two telescopes (TEC 140/f5 and ASI 6200MM) between 5:08–5:22 UT on November 9, 2025.

The image shows two anti-tail jets out to 10 arcminutes towards the Sun accompanied by a longer collimated jet, extending away from the Sun out to an angular separation of 30 arcminutes, roughly the diameter of the Sun or the Moon.

At the current distance of 3I/ATLAS from Earth, 326 million kilometers, these angular extents correspond to spatial sizes of 0.95 million kilometers for the sunward anti-tail jets and 2.85 million kilometers for the tail jet away from the Sun. This enormous spatial scale is three orders of magnitude larger than the scale of the glowing halo around 3I/ATLAS in the Hubble Space Telescope image from July 21, 2025 (reported here).

ESA’s latest study could hold the key to sustaining astronauts on long-duration missions by introducing a groundbreaking protein powder made from hydrogen-oxidizing bacteria.

An interstellar comet that originated outside our solar system has just made its closest pass to the sun, brightening dramatically and rapidly as it did so. The reason for the sudden extreme activity is currently puzzling scientists.

A stranger in the neighborhood The latest visitor to our corner of the galaxy was first spotted on July 1, 2025, by astronomers and officially named comet 3I/ATLAS. It’s only the third interstellar comet ever recorded and was calculated to be on a course that would take it close to the sun without plunging into it.

As the object neared its closest point to our star (perihelion), the immense solar glare made it virtually impossible for Earth-based telescopes to see it. So astronomers turned to space-based solar observatories like SOHO, STEREO-A and GOES-19 to keep a watchful eye.

NASA’s Perseverance rover has uncovered powerful new evidence that Mars’ Jezero Crater once hosted multiple rounds of flowing water, each creating conditions that could have supported life.

Cassini’s new analysis shows Saturn’s moon Enceladus leaking heat from both poles, not just the south. This balanced heat flow suggests its underground ocean could stay liquid for geological ages, supporting conditions for life. Scientists even used temperature data to estimate ice thickness, pre

The C-STARS experiment aims to gather data on how astronauts maintain mental health while on long-duration missions.

As more and more exoplanets are discovered throughout the galaxy, scientists find some that defy explanation—at least for awhile. A new study, published in Nature, describes a process that might explain why a large portion of exoplanets have water on their surface, even when it doesn’t make sense.

Water where it shouldn’t be A particular category of exoplanets that are between the size of Earth and Neptune, referred to as “sub-Neptunes,” generally have a rocky core, which is surrounded by an envelope of either hydrogen or water. This makes sense if the planet forms farther away from its host planet, in a region where water can precipitate as ice. However, some of these planets are found much closer to their host stars, where it should be too hot to hold water at the surface.

While some planets may accumulate a certain amount of water from incoming comets and asteroids, that doesn’t work for these planets either. The amount of water that is typically found on their surfaces is too high for such explanations. Past experiments have also shown that hydrogen can reduce iron in silicates, producing water. However, they came to the conclusion that only small amounts of water would be produced at the kind of high pressures experienced at the surface of a sub-Neptune planet.
