A seat on a Russian spaceflight could cost around 2 billion rubles, roughly $25 million, based on total launch expenses split across participants. There is an important detail: every mission would still require at least two professional crew members for safety and emergency response, so not all seats would be open to tourists. Roscosmos describes this as a premium category because launch systems and spacecraft operations are still costly. It also extends the idea of space tourism beyond flying, including factory visits, launch facility access, and engine test site tours. That pricing is similar to past orbital tourism missions. For now, access remains limited to very wealthy individuals, though costs could decline over time if reusable spacecraft and more frequent launches become standard.

Alexei Leonov’s 1965 spacewalk was a milestone in human history—and a terrifying survival story. After leaving Voskhod 2, he found that the vacuum had inflated and stiffened his suit so badly that he struggled to re-enter the airlock. He made it back only after lowering suit pressure and forcing himself through. Then the mission suffered more problems, including re-entry trouble and a remote landing in a frozen Siberian forest. Leonov and Pavel Belyayev spent two nights waiting for rescue. This mission opened the era of EVA while showing just how dangerous it would be.

New observations of Cepheus A HW2 suggest cosmic radiation may do more than break molecules apart. In the most strongly irradiated region around this massive young star, astronomers detected abundant complex organic molecules, including methanol, methyl cyanide, acetaldehyde, ketene, and methyl formate. The likely process is that cosmic rays disrupt simple ices on dust grains, trigger new chemical reactions, and help release freshly formed organics into space. Even more surprising, this irradiated zone showed much richer chemistry than a nearby control region with ordinary radiation levels. The discovery points to a bigger possibility: violent stellar nurseries may be active sites of prebiotic chemistry, broadening where the building blocks of life could arise in the Universe.

NASA is considering whether the Hubble Space Telescope could be lifted into a higher orbit to delay reentry beyond 2033. The concept is tied to a commercial rendezvous-and-boost mission planned for the Neil Gehrels Swift Observatory. If that mission succeeds and NASA finds a way to lower Hubble’s operating costs, the observatory could remain scientifically active into the 2040s, helping bridge the gap before future flagship missions arrive.

Astronomers have directly tracked the rotation of the planet-forming disk around AB Aurigae and uncovered clear signs of active planet formation. Observations with SPHERE on the Very Large Telescope show gas and dust moving in patterns that simple gravity does not fully account for, likely because massive protoplanets are already disturbing the disk. Together with AB Aurigae b and the system’s spiral arms, shadows, and twisted features, the data offer one of the strongest real-time views yet of a young solar system emerging from gas and dust.

A new study proposes that vast numbers of unseen interstellar comets and asteroids may contribute part of the Milky Way’s apparent missing mass. Starting from known interstellar visitors such as 1I/‘Oumuamua, 2I/Borisov, and 3I/ATLAS, researchers used statistical models to estimate how much mass a hidden Galactic population of similar objects could add. Their result suggests these wanderers might explain about 13% to 45% of the discrepancy inferred from the Milky Way’s rotation curve. Important caution: this hypothesis is based on very limited observational evidence and broad extrapolation from only a few detections. Even if supported, it would not remove the need for dark matter, though it could reduce the amount required and affect how some detection results are interpreted. Future sky surveys should provide the data needed to test whether these hidden interstellar bodies meaningfully contribute to the Galaxy’s mass budget. Follow for the next sky survey result that could prove this idea right or wrong. #s

A new study examined whether NASA’s planned Habitable Worlds Observatory could have detected life on Earth from light-years away at different stages of our planet’s history. By modeling eras from the Archean Earth—when oxygen was scarce and life was mostly microbial—to the modern oxygen-rich world, researchers found that the telescope should be able to identify major biosignatures such as oxygen, ozone, water vapor, methane, and carbon dioxide if it reaches the needed spectral resolution. The work also sets concrete design goals. Relatively modest ultraviolet and visible-light performance may be enough for ozone and oxygen detection, while stronger infrared resolution is more important for telling possible biological signals apart from geological ones. The bigger implication is extraordinary: a future observatory like this might provide humanity’s first strong evidence that life exists on another world. If we can read life in Earth’s old light, what world should we search next? #nasa #habitableworldsobservat

Astronomers are testing a powerful new way to find faint moving objects in telescope data. YOSO, or “You Only Stack Once,” avoids the slow step of checking thousands of possible trajectories. Instead, it analyzes changes in pixel brightness over time and combines images only once, making the search far more efficient. The system uses a YOLOv8-based deep-learning model to detect extremely dim moving targets while filtering out image artifacts, satellite trails, and cosmic-ray strikes. In tests on Victor M. Blanco Telescope observations, it detected 11 previously unknown trans-Neptunian objects and 216 other moving bodies, including some overlooked by standard methods. With processing under 11 milliseconds and about 99% catalog purity, YOSO looks well suited for the massive datasets expected from the Vera C. Rubin Observatory. It could also strengthen future planetary defense efforts by helping missions like NEO Surveyor find potentially hazardous asteroids faster. Follow for more breakthrough space tech expla

A major first in exoplanet science: the James Webb Space Telescope has directly studied the surface of a rocky exoplanet. The world is LHS 3844 b, a super-Earth around 50 light-years away that orbits its red dwarf star every 11 hours and reaches about 725°C on its dayside. Webb detected no atmosphere and instead found evidence for a dark surface likely dominated by volcanic basalt. Scientists say it may be a younger lava-covered terrain or an older landscape darkened by long-term space weathering. This breakthrough shows Webb can begin probing the geology of distant rocky worlds, opening a new era in the study of potentially Earth-like planets.

Astronomers have reported their most precise late-universe measurement of cosmic expansion so far, and it again supports the Hubble tension. Using several independent distance indicators—Cepheid stars, red giant stars, and supernovae—the H0 Distance Network measured a Hubble constant of 73.5 km/s/Mpc. That agrees with previous late-universe measurements but remains well above the ~67 km/s/Mpc value inferred from early-universe observations of the Cosmic Microwave Background within the standard cosmological model. The key point is that the new result has less than 1% uncertainty and remains stable even when individual methods are removed. That makes it increasingly difficult to blame the discrepancy on observational error alone. If confirmed by future observatories such as the Nancy Grace Roman Space Telescope, this tension could signal missing physics in our current model of the universe, including new particles, unexpected dark energy behavior, or modifications to gravity.

New research suggests dwarf galaxies may not be random collections of stars and dark matter after all. Simulations indicate that dark subhaloes—small, invisible clumps of dark matter—can gradually heat stellar motions through repeated gravitational nudges, pushing stars into wider orbits. Over time, both isolated dwarf galaxies and those near larger hosts may move toward a common stable structure, with tidal effects accelerating the process. This may offer a possible explanation for the cusp-core problem and a new way to understand how dark matter shapes galaxies.
