    Science is broken--just like every discipline in which 'expertise' is the product being sold for money and prestige. We've seen the practical effects for quite a while. 'Experts' have been getting everything wrong for a long time, and in increasingly dangerous ways. A few years ago, a scandal broke out regarding psychological and sociological research--almost no experimental results were duplicable, suggesting that the 'conclusions' were as valuable as a $3 bill. Nutrition research is total bunkum. Anybody who followed the government's nutrition advice got fat, and the American diet is now filled with poison. Climate 'science?' It's nearly impossible to...

    Scientists are racing to learn as much as possible about the interstellar comet 3I/ATLAS before it fades from view forever The interstellar object 3I/ATLAS appears as a blurry, dust-shrouded dot in this image from the Gemini North telescope. Future observations should reveal much more about this mysterious object, the third known visitor from beyond our solar system. International Gemini Observatory/NOIRLab/NSF/AURA/K. Meech (IfA/U. Hawaii) Image Processing: Jen Miller & Mahdi Zamani (NSF NOIRLab) (CC BY 4.0) ================================================================= Earlier this month astronomers were thrilled to discover only the third known interstellar object ever seen in our solar system. Now dubbed 3I/ATLAS, the...

    Explanation: It came from outer space. An object from outside our Solar System is now passing through at high speed. Classified as a comet because of its gaseous coma, 3I/ATLAS is only the third identified macroscopic object as being so alien. The comet's trajectory is shown in white on the featured map, where the orbits of Jupiter, Mars, and Earth are shown in gold, red, and blue. Currently Comet 3I/ATLAS is about the distance of Jupiter from the Sun -- but closing, with its closest approach to our Sun expected to be within the orbit of Mars in late October....

    Explanation: Discovered on July 1 with the NASA-funded ATLAS (Asteroid Terrestrial-impact Last Alert, System) survey telescope in Rio Hurtado, Chile, 3I/ATLAS is so designated as the third known interstellar object to pass through our Solar System It follows 1I/ʻOumuamua in 2017 and the comet 2I/Borisov in 2019. Also known as C/2025 N1, 3I/ATLAS is clearly a comet, its diffuse cometary coma, a cloud of gas and dust surrounding an icy nucleus, is easily seen in these images from the large Gemini North telescope on Maunakea, Hawai‘i. The left panel tracks the comet as it moves across the sky against fixed...

    Astronomers at the Planetary Virtual Observatory and Laboratory (PVOL) are appealing for help, after an image taken by NASA's Mario Rana appears to show an object slamming into Saturn.Saturn, like Jupiter, is a gas giant. With their impressive masses, you would expect these giants to attract their share of asteroid impacts. Unlike terrestrial planets, which are usually left with an obvious crater after impact, on gas giants, it is not entirely obvious. With outer layers primarily composed of hydrogen and helium, any trace of an impact can disappear.Astronomers have attempted to model how many impacts take place on the gas...

But what would this complex and exotic brew smell like? It turns out that everyone—not just Mars explorers—might be able to find out, because there may be ways to recreate whiffs of the Red Planet here on Earth.

    In a groundbreaking discovery published in The Planetary Science Journal, a team of astronomers led by the Center for Astrophysics | Harvard & Smithsonian has confirmed the existence of a rare object located far beyond Neptune. Known as 2020 VN40, this trans-Neptunian object is in a unique orbital resonance with the giant planet Neptune. For every ten orbits Neptune completes, 2020 VN40 completes one orbit around the Sun. This rare alignment provides key insights into how objects in the outer solar system behave and evolve over time. The research, which draws from extensive observations made by the Large Inclination Distant...

    Astronomers have discovered a massive new solar system body located beyond the orbit of Pluto. The weird elongated orbit of the object suggests that if "Planet Nine" exists, it is much further from the sun than thought, or it has been ejected from our planetary system altogether. The strange orbit of the object, designated 2023 KQ14 and nicknamed "Ammonite," classifies it as a "sednoid." Sednoids are bodies beyond the orbit of the ice giant Neptune, known as trans-Neptunian objects (TNOs), characterized by a highly eccentric (non-circular) orbit and a distant closest approach to the sun or "perihelion." The closest distance...

    original to FR | July 16, 2025 | Peter O'Donnell
    I wondered if any FRiends were interested in prime numbers. You'll know that prime numbers are integers, and those which have only two factors, 1 and themselves. Except for 2, all other primes are odd numbers. By convention, the number 1 is not considered prime (but this is strictly a matter of definition because 1 does not entirely contradict the premise of being a multiple of 1 and itself). I cannot post this entire thread in one post so if you come across it in an early stage, be aware that a number of posts will follow rapidly until I...

    Welcome to the neighborhood, Ammonite. The object during observations. Image credit: NAOJ/ASIAA The Subaru telescope located at the Mauna Kea Observatory on Hawai'i has found a new world within our Solar System, dubbed "Ammonite" by the team who found it. In 2003, NASA-funded researchers spotted what was then the most distant object discovered in our Solar System. The dwarf planet, named Sedna after the Inuit goddess of the sea, was found over 12.9 billion kilometers (8 billion miles) from Earth, potentially making it an inner object of the hypothetical "Oort cloud" surrounding our Solar System. "Sedna is distinguished among other...

    In the vast expanse between Uranus and Neptune, a team of researchers have uncovered something really quite extraordinary, a minor planet that has been locked in precise gravitational manouevres with Uranus for at least a million years. This discovery sheds new light on the complex dynamics that govern our Solar System's outer reaches. The object in question, designated 2015 OU₁₉₄, belongs to a class of small bodies called Centaurs, rocky and icy objects that orbit between Jupiter and Neptune. What makes this particular Centaur special is its remarkably stable relationship with Uranus, locked in what is known as a 3:4...

    Gravitational waves from massive black holes challenge current astrophysical models The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves using the US National Science Foundation (NSF)-funded LIGO observatories. The powerful merger produced a final black hole approximately 225 times the mass of our Sun. The signal, designated GW231123, was detected during the fourth observing run of the LVK network on November 23, 2023. LIGO, the Laser Interferometer Gravitational-wave Observatory, made history in 2015 when it made the first-ever direct detection of gravitational waves, ripples in space-time. In that case, the...

Using ultra-high-resolution simulations and sophisticated modeling, researchers at Durham University predict that the Milky Way could be surrounded by up to 100 previously undetected satellite galaxies. These faint, elusive “orphan galaxies” may have been stripped of their dark matter halos, making them nearly invisible to current telescopes. But with the advent of powerful new instruments like the Rubin Observatory, scientists believe we’re finally approaching the ability...
