Discover what exist in the universe
The Nature of Dark Energy Dark energy, the enigmatic force driving the universe's accelerated expansion, remains one of the greatest mysteries in cosmology. Accounting for approximately 70% of the universe's content, it eludes direct observation and is inferred solely from the universe's behavior. The Lambda Cold Dark Matter (LCDM) model, […]
Identifying Circumpolar Constellations Circumpolar constellations are visible year-round, never setting below the horizon. Two prominent examples are Ursa Major and Cassiopeia. Ursa Major, also known as the Big Dipper, consists of seven stars forming a saucepan-like shape. To find Polaris (the North Star): Cassiopeia displays a distinctive W or M […]
Porphyrion: The Largest Black Hole Jet System The discovery of Porphyrion, a black hole's jet system stretching 23 million light-years, challenges our understanding of cosmic structures. Named after a giant from Greek legend, it spans a length equivalent to 140 Milky Ways lined up. Astronomers at Caltech and Leiden University, […]
Understanding Lunar Gardening Lunar gardening connects Earth and Moon cycles to guide planting practices. The Moon's phases influence soil moisture and plant growth, similar to its effect on tides. From new Moon to full Moon, above-ground plants like watermelons, beans, and corn thrive. As the Moon wanes, root crops such […]
Overview of 2025 Lunar Eclipses On March 13-14, 2025, North America will witness a total lunar eclipse, or blood moon. This occurs when Earth positions itself between the sun and a full moon, casting its shadow on the lunar surface. The moon takes on a reddish hue due to sunlight […]
Full Moon Names and Dates The lunar calendar for 2025 brings a series of captivating Full Moons, each with its unique name and significance: These names, rooted in Native American, Colonial American, and other North American traditions, reflect seasonal changes and natural phenomena. For instance, the Wolf Moon is named […]
Detection of Dimethyl Sulfide (DMS) The discovery of dimethyl sulfide (DMS) in K2-18b's atmosphere has intrigued astronomers. This molecule, often produced by Earth's marine life, appears as a potential indicator of life on another planet. However, experts remain cautious about directly linking it to extraterrestrial microorganisms. Recent data from the […]
Cosmic inflation offers insights into the universe's early moments, addressing puzzles left by the Big Bang theory. Through theoretical constructs and observational evidence, we gain a deeper understanding of how our universe came to be. The Basics of Cosmic Inflation Cosmic inflation theory posits that shortly after the Big Bang, […]
Measurement of Distance Edwin Hubble's 1923 calculation of Andromeda's distance at 1 million light-years, later corrected to 2.5 million light-years, was a milestone in astronomy. This discovery proved that spiral nebulae were galaxies beyond the Milky Way, expanding our understanding of the universe. While parallax measurement is limited for cosmic […]
In space, objects like 'Oumuamua challenge our understanding of the universe. These interstellar visitors, with their unusual paths and characteristics, offer valuable insights into the dynamics of planetary systems beyond our own. Discovery and Characteristics of 'Oumuamua In October 2017, 'Oumuamua entered our solar system unexpectedly, catching astronomers' attention using […]
