Detection of DMS on K2-18b NASA's James Webb Space Telescope has potentially detected dimethyl sulfide (DMS) in the atmosphere of K2-18b. This molecule, often produced by marine algae on Earth, hints at possible life beyond our solar system. However, the scientific community remains cautious. Detecting molecules in space relies on […]
Formation of Neutron Stars The life of a massive star culminates in a dramatic sequence of events. As it exhausts its hydrogen fuel, gravity initiates a series of collapses, creating heavier elements up to iron. When fusion ceases, the star's core implodes, triggering a supernova explosion. The resulting cosmic upheaval […]
Origins of the Universe The universe began about 13.7 billion years ago, compressed into an incredibly tiny point. Cosmic inflation, occurring in less than 10-32 of a second, rapidly expanded the universe faster than light speed. After this initial expansion, the universe settled to form particles that would eventually become […]
The story of the Hubble Constant reflects humanity's pursuit of understanding the universe's expansion, marked by significant milestones and ongoing debates. Historical Development of the Hubble Constant Edwin Hubble's observation that galaxies are moving away from us revolutionized our cosmic perspective. Before Hubble, Vesto Slipher noted that spiral nebulae were […]
Exciting Discovery on K2-18b: Potential Signs of Life? The astronomical community is buzzing with excitement over recent observations of exoplanet K2-18b. Located approximately 120 light-years away in the Leo constellation, this intriguing world has captured attention due to findings from the James Webb Space Telescope (JWST). Scientists have detected potential […]
Atmospheric Composition of K2-18b The atmosphere of K2-18b presents an intriguing puzzle. Methane and carbon dioxide have been detected, suggesting a hydrogen-rich atmosphere possibly enveloping an ocean. Hints of dimethyl sulfide, a molecule often associated with marine life on Earth, have raised interesting questions about potential biosignatures. K2-18b orbits a […]
Biological Interactions The idea that lunar cycles may influence menstrual cycles has intrigued researchers for years. While both cycles average around 29 days, recent extensive analyses present a nuanced view of any potential connection. A comprehensive 2019 study collecting data from over a million users of a period tracking app […]
Definition and Calculation of a Light-Year A light-year measures the distance light travels in one year, approximately 9.46 trillion kilometers. Light moves at 299,792 kilometers per second, covering this vast distance in about 31.54 million seconds (one year). Light-years are used instead of kilometers or miles due to the immense […]
Principles of Feng Shui and Astrology Feng Shui focuses on the energy of spaces, considering factors like land elevation, water, and mountains to create environments that naturally attract prosperity. Astrology connects to the rhythm of the universe, guiding life's significant moments using celestial cues. Nine Ki astrology uses numbers to […]
Understanding K2-18b's Atmospheric Composition K2-18b, an exoplanet orbiting a red dwarf star, showcases an atmosphere quite distinct from Earth's. Its composition is primarily hydrogen, with traces of methane and carbon dioxide. Unlike our planet's nitrogen and oxygen-rich atmosphere, K2-18b's hydrogen envelope is thick enough to drastically differ from Earth's atmospheric […]
