Scientists have identified a new minor planet beyond Pluto , enhancing our knowledge of the solar system 's outer boundaries. The celestial body, designated as 2017 OF201 , ranks among the largest distant objects ever detected, providing fresh insights into the Kuiper Belt and the remote regions of our planetary system.The International Astronomical Union's Minor Planet Center officially recognised 2017 OF201 after its detection in archived telescope data. The object's remarkable characteristics include its substantial size and distinctive orbital path. Its estimated diameter ranges from 470 to 820 kilometres (approximately 290 to 510 miles), placing it amongst known dwarf planets and substantial asteroids like Ceres.Its highly eccentric orbit varies between 45 astronomical units (AU) from the Sun - approximately 45 times Earth's distance from the Sun - to a remarkable 838 AU at its apex. For context, Neptune orbits at about 30 AU. This extensive elliptical trajectory classifies 2017 OF201 as an extreme trans-Neptunian object (ETNO), belonging to a category of bodies residing in the solar system's furthest regions.The Kuiper Belt, home to Pluto and other frozen bodies, remains an enigmatic region containing remnants from the solar system's formation over 4.5 billion years ago. The discovery of 2017 OF201 assists astronomers in understanding the origin, evolution, and formation of these objects, providing data about the solar system's early conditions.The discovery of 2017 OF201 contributes to ongoing investigations regarding a potential ninth planet beyond Neptune. The theoretical "Planet Nine" would exert gravitational influence over several ETNOs' orbits. While 2017 OF201's trajectory doesn't precisely align with Planet Nine predictions, each newly discovered outer solar system object provides crucial data for refining astronomical models and theories.Beyond the Planet Nine theory, studying distant objects like 2017 OF201 enhances understanding of the solar system's outer structure and mechanics. These objects serve as preserved evidence of planetary movements, impacts, and other historical events.Future facilities like the Vera C. Rubin Observatory will accelerate the identification of distant solar system objects, improving our understanding of these remote areas. Current research continues to illuminate the solar system's boundaries and the principles governing our cosmic vicinity.Overall, 2017 OF201 represents a significant discovery among trans-Neptunian objects. It addresses current knowledge gaps while extending our understanding of the solar system's reach, establishing foundations for future astronomical research.

Deadly brain-eating amoeba kills Texas woman: how to be safe?
What is Naegleria fowleri? Naegleria fowleri is a free-living, single-celled amoeba found in warm freshwater environments worldwide, such as lakes, rivers, hot springs, and poorly maintained pools. It is commonly called the 'brain-eating amoeba' because it can cause a fatal brain infection. How do people get infected? Infection occurs when water containing the amoeba enters the nose, usually during swimming, diving, or nasal irrigation with contaminated water. Drinking contaminated water does not cause infection. What are the symptoms? Early symptoms include headache, fever, nausea, and vomiting. As the disease progresses, symptoms may include stiff neck, confusion, seizures, hallucinations, and coma. Death usually occurs within 5 days of symptom onset. How common are infections? Infections are extremely rare, with fewer than 10 cases reported annually in the U.S. over the past five decades Can the infection be treated? Treatment options are limited and often unsuccessful. Some experimental therapies, such as miltefosine, have shown promise if administered early, but survival remains rare. How can infection be prevented? Use only distilled, sterile, or previously boiled and cooled tap water for nasal irrigation. Avoid submerging your head in warm freshwater, especially during the summer months. The Science Behind Naegleria fowleri Live Events (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel A 71-year-old Texas woman died after contracting a rare but deadly infection caused by the brain-eating amoeba Naegleria fowleri . According to the Center for Disease Control and Prevention (CDC), the woman used untreated tap water from her RV's supply for nasal irrigation, a practice that allowed the amoeba to enter her body through her days, she developed severe neurological symptoms, including headache, fever, confusion, and seizures. Despite rapid medical intervention, she succumbed to the infection just eight days after symptoms began. The CDC stresses that such infections are extremely rare but almost always fatal, with only four survivors among 164 reported U.S. cases from 1962 to fowleri is a thermophilic (heat-loving) amoeba that thrives in warm freshwater environments, particularly during summer months. It exists in three life stages: cyst (dormant and resistant), flagellate (transient and mobile), and trophozoite (active and feeding).The trophozoite stage is the infectious form, capable of invading the nasal passages and migrating to the brain via the olfactory nerve, where it causes primary amebic meningoencephalitis (PAM).The amoeba is classified as a free-living organism, meaning it does not require a host to survive. Instead, it feeds on bacteria and organic matter in the environment. While most exposures do not result in infection, when the amoeba enters the nose, it can rapidly cause severe brain inflammation and tissue destruction, leading to death in nearly all fowleri's ability to adapt to various environments and its near-universal presence in warm freshwater underscores the importance of safe water practices, especially for activities that involve nasal exposure.
