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...

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...

NASA's James Webb Space Telescope recently detected a planet that could possibly sustain life based on temperature readings, which has a mass approximately 100 times the size of Earth. The planet, which astronomers believe is orbiting a young red dwarf star approximately 34 light years away, has been dubbed TWA 7b and is roughly the size of Saturn. An initial analysis suggests the planet has a temperature of near 120 degrees Fahrenheit, which is warm enough to support life. Scientists believe life can grow and reproduce starting at about 5 degrees Fahrenheit and as high as 251 degrees Fahrenheit, per...

Analysis of swabs from China's Tiangong Space Station has revealed a new strain of bacteria sporting new adaptations for surviving outer space. Scientists have discovered a new microbe never-before-seen on Earth inside China's Tiangong space station. The new strain of bacteria, named Niallia tiangongensis after the space station, is a variant of a soil-dwelling terrestrial microbe that can cause sepsis, and was found inside one of the station's cabins. Now, a new analysis of the strain has revealed that the bacterium isn't only one of a kind, but has also picked up some key adaptations that could be helpful in...

A distant star system that scientists described as abnormal, chaotic, and strange is finally coming into focus, thanks to NASA's James Webb Space Telescope. Using its powerful Near-Infrared Camera (NIRCam), Webb has captured a rare image of one of two known planets orbiting the star 14 Herculis, located about 60 light-years from Earth in the Milky Way.The planet, known as 14 Herculis c, stands out for how incredibly cold it is. While astronomers have discovered nearly 6,000 exoplanets, only a small handful have been directly imaged, and most of those are extremely hot, with temperatures soaring into the hundreds or...

A groundbreaking discovery in the field of exoplanet research is forcing scientists to reconsider long-held theories about how planets form. An international team of astronomers, led by the University of Warwick, recently revealed the existence of TOI-6894b, a giant planet orbiting the ultra-low-mass star TOI-6894, in a study published in Nature Astronomy. This find has raised significant questions about the accuracy of the prevailing models of planet formation, which have long argued that gas giants like TOI-6894b cannot form around small stars. Unlikely Host Star: The Tiny TOI-6894 At the heart of this discovery is TOI-6894, a red dwarf star...

A bizarre planet may orbit two brown dwarfs in a steep, pole-skimming path—an unheard-of tilt that challenges our understanding of planetary motion. Detected via gravitational wobbles, it might be the first polar-orbiting circumbinary planet ever found. Credit: SciTechDaily.com =================================================================== Astronomers have discovered one of the weirdest planetary systems yet: a possible planet, 2M1510 b, appears to orbit over the poles of two brown dwarfs in a sharply tilted path—almost perpendicular to their own orbit. This freakish setup, unlike anything in our solar system, was detected not by a dip in starlight but through subtle gravitational wobbles captured using ESO’s Very...

Scientists modeling planetary system formation scenarios say there could be a 40% chance that a hypothetical ‘Planet Nine’, believed by many to lurk at the outer reaches of the Sun’s orbit, could exist. The study, conducted by researchers at Rice University, also suggests most of these planets don’t end up captured by their host star’s gravity but instead get ejected from the star’s orbit altogether and spend the rest of their lives roaming the galaxy as “rogue planets.” “Our simulations show that if the early solar system underwent two specific instability phases—the growth of Uranus and Neptune and the later...

When astronomers announced last month they might have discovered the most promising hints of alien life yet on a distant planet, the rare good news raised hopes humanity could soon learn we are not alone in the universe. But several recent studies looking into the same data have found that there is not enough evidence to support such lofty claims, with one scientist accusing the astronomers of "jumping the gun". Two of Madhusudhan's former students, Luis Welbanks of Arizona State University and Matthew Nixon of Maryland University, were among the researchers who have since re-analysed the data behind the announcement....

Researchers using NASA's Hubble Space Telescope have discovered the magnetar called SGR 0501+4516 is traversing our galaxy from an unknown place of origin. Researchers say that this runaway magnetar is the likeliest candidate in our Milky Way galaxy for a magnetar that was not born in a supernova explosion as initially predicted. It is so strange it might even offer clues to the mechanism behind events known as fast radio bursts...But a decade-long study with Hubble cast doubt on the magnetar's birthplace. After initial observations with ground-based telescopes shortly after SGR 0501+4516's discovery, researchers used Hubble's exquisite sensitivity and steady...
