🚨 SCIENTISTS HAVE FOUND COMPLEX ORGANIC MOLECULES INSIDE MATERIAL RETURNED FROM ASTEROID RYUGU. Researchers analyzing samples from Japan’s Hayabusa2 mission have identified unusually large carbon-rich compounds in the asteroid. These molecules are more complex than many previously found in meteorites and may preserve chemical clues from the early Solar... System long before life existed on Earth. While this is not evidence of alien life, it shows that some of the building blocks associated with life’s chemistry were already forming in space billions of years ago. Why this matters: • It strengthens the idea that asteroids and comets could have delivered organic material to early Earth • It gives scientists a rare look at pristine chemistry from the birth of the Solar System • It helps us understand how complex molecules can form in space without biology • It has implications for the search for life on other planets and moons The deeper question: Did the ingredients for life originate on Earth… or were they seeded across the Solar System by asteroids like Ryugu? We’re now getting closer to answering that question with actual material collected from space rather than just meteorites that survived atmospheric entry.

🚨 It's official: JWST Will Observe Interstellar Object 3I/ATLAS On August 6, 2025 🚨 The schedule from Space Telescope Science Institute shows two back to back NIRSpec IFU spectroscopy runs (10:15 UTC & 11:03 UTC) that will track the objects motion across the sky. JWST will look for chemical fingerprints, as it can detect water, CO₂, CO & other volatiles in infrared long before the comet reaches perihelion on Oct 29. Early phase spectra 'may' reveal the composition of pristine material untouched by the Sun for millions (or billions) of years. This is only the 3rd confirmed visitor from beyond our solar system, following Oumuamua & 2I/Borisov. JWST's eyes on 3I/ATLAS could tell us not just what it’s made of but where in the galaxy it may have come from. #JWST #3IATLAS #Astronomy #Space #Interstellar #NASA #Comet

Space objects such as meteoroids and asteroids move across the solar system and can collide with both Earth and the Moon. However, the Moon shows far more visible impact marks on its surface. One main reason is that Earth has a thick atmosphere that protects the planet. When many meteoroids enter Earth’s atmosphere, they burn up due to friction before they can reach the ground. This process creates the bright streaks of light we call shooting stars. The Moon, however, has almost no atmosphere, so incoming space rocks are not slowed down or burned up. They travel directly to the lunar surface and strike it at very high speed. Each collision creates an impact crater, throwing dust and rocks outward from the impact point. Over billions of years, thousands of these impacts have covered the Moon with craters. Unlike Earth, the Moon also has no wind, water, or weather to erase these craters, so they remain visible for millions or even billions of years. This is why the Moon looks heavily cratered when we observe it from Earth through telescopes.

Another explanation for Oumuamua's unusual shape has been proposed The asteroid Oumuamua, which flew through the Solar System in 2017, amazed scientists with its unprecedentedly elongated shape. It is 230 meters long and about 35 meters wide. Astronomers have never seen such objects before and tried to explain its origin. Oumuamua is the first known object to arrive from interstellar space. Its trajectory and speed left no doubt that it does not belong to the Solar System. The object rotated around its axis, changing its brightness, which made it possible to determine its size.

Did you know the James Webb Space Telescope isn’t orbiting Earth at all? The James Webb Space Telescope operates near the Sun–Earth L2 point, about 1.5 million km from Earth. From there, the Sun, Earth, and Moon stay on the same side of the telescope, allowing its giant sunshield to block their heat and light at the same time. That keeps Webb cold and stable enough to detect extremely faint infrared signals from deep space. Because of this, Webb can peer through clouds of cosmic dust and observe galaxies whose light has traveled for more than 13 billion years. Every image it captures is not just a view across space, but a look back into the early history of the universe.

It is crazy that some computer scientists are saying that chemistry experiments don’t have to happen ‘in the real’. I guess we need to invent ‘Chemportation’ which teleports molecules from simulation to the real world using Molecular Actuation Ghosts In Chemistry (MAGIC).

Some microorganisms may have little trouble surviving being blasted into space on planetary debris when an asteroid hits. That finding comes from subjecting a particularly hardy species of desert bacteria to a simulation of the immense forces produced by an asteroid collision. The research lends support to the idea that life jettisoned off world could spread to and seed new worlds by clinging to space rocks. Learn more: News from Science

Crimson Desert has this surface shader.. It has a transformative effect on the game visuals and it's seemingly applied to every object in the game. It doesn't look like tessellation, it appears to have artifacts from a screen-space effect. I believe they are using the height maps from every PBR material in the game to create some sort of screen space displacement mapping.

Meet the Xenobots, they are not machine, they are PROGRAMMABLE biological robots that can REPRODUCE. — The concept of xenobots has been a fascinating topic in the realm of developmental biology, and the latest findings have left me utterly astonished. These microscopic entities have been observed to not only self-assemble into complex forms but also exhibit a level of autonomy and adaptability that challenges our conventional understanding of multicellular organization. The researchers, led by Michael Levin, have successfully demonstrated that embryonic frog cells can spontaneously form into xenobots, which are capable of movement, self-organization, and even communication with one another. These xenobots are not merely passive aggregates of cells but rather dynamic systems that can adapt to their environment and respond to stimuli and be programmed to a degree. What's even more remarkable is that these xenobots have been found to be capable of reproduction. As Eva Jablonka, an evolutionary biologist, noted, "a xenobot may be induced to fragment and form two small ones," which raises the possibility of these entities undergoing a form of evolution. This has significant implications for our understanding of the origins of multicellularity and the evolution of complex life forms. The ability of xenobots to self-organize and adapt to their environment is thought to be mediated by a complex interplay of genetic and environmental factors. Levin suggests that the genome provides a set of rules and tendencies that allow cells to collectively "compute" their own solutions to growth and form, rather than being rigidly determined by a predetermined plan. The potential applications of this research are vast and varied, ranging from regenerative medicine to the development of novel biomaterials to a dystopian nightmare. However, what's most exciting is the prospect of gaining a deeper understanding of the fundamental principles that govern the emergence of complex life forms. As Levin notes, "we need a science of where larger-scale goals come from," and the study of xenobots may provide a key insight into this question. The discovery of xenobots and their remarkable properties has opened up a new frontier in the study of developmental biology and has significant implications for our understanding of the evolution of complex life forms.

Artificial embryo samples aboard Tiangong Space Station for life science research Space "artificial embryo" samples and other life science experiments delivered by the Tianzhou-10 cargo spacecraft have been installed into experiment modules aboard China's Tiangong space station, the Technology and Engineering Center for Space Utilization under the Chinese Academy of Sciences (CAS) said on Wednesday. The "artificial embryos" are stem cell-derived artificial human embryos. The embryos, though not true life forms and unable to develop into human babies, will help simulate the earliest stages of human development. Once the experiments are completed, the artificial embryo samples will be frozen in orbit and then returned to Earth on a future mission for side-by-side analysis with ground-based controls in laboratories on the ground. This effort is part of a broader suite of 41 space science experiments being deployed aboard Tiangong, supporting its latest round of research on the orbiting laboratory.
