Since 1995, scientists have found more than 4,000 Earth-like exoplanets. It would surely be your surprise that these planets are outside our solar system. NASA’s Exoplanet Exploration page says the Kepler Space Telescope found most of these. Astronomers really wanted to find the first “alien Earth.” The Earth-like planets in the Milky Way. New discoveries […]
White Dwarf Stars: Unveiling the Secrets of Stellar Remnants In the depths of the cosmos lie objects that shine as testaments to the end of a star’s life – white dwarf star. These dense, Earth-sized remnants are the final stage for most stars in the universe, including our own Sun. Once a star exhausts its […]
The quest to find Earth-like planets beyond our solar system has led to the discovery of a new category of exoplanets known as “Super Earth.” These planets, larger than Earth but smaller than ice giants like Neptune, have captured the imagination of scientists and space enthusiasts alike. Among these, TOI-715 b stands out as a […]
Introduction NASA’s James Webb Space Telescope (Webb) has been instrumental in unraveling the mysteries of the universe, providing us with groundbreaking observations and insights. In its relentless pursuit of knowledge, Webb has recently made a remarkable discovery in the Beta Pictoris System—a dusty ‘Cat’s Tail’ that has captivated the scientific community. This article delves into […]
Introduction In an unprecedented breakthrough that is rewriting textbooks and reshaping our understanding of exoplanetary atmospheres, the James Webb Space Telescope (JWST) has discovered the presence of quartz crystals in the atmosphere of the distant exoplanet WASP-17b. Far from being an arbitrary discovery, the identification of these crystals changes our entire comprehension of cloud composition […]
The cosmos is a treasure trove of celestial objects, each with its own unique story and significance. Among these cosmic wonders, “433 Eros”, a near-Earth asteroid, stands out as an intriguing and enigmatic celestial body. This small, rocky world has captivated the imagination of astronomers and space enthusiasts alike, offering valuable insights into the history […]
TRAPPIST-1 c Atmosphere’s Analysis A team of scientists from around the world used NASA’s James Webb Space Telescope to calculate the amount of heat energy emitted by TRAPPIST-1 c, a rocky exoplanet. The findings indicate that, if there is indeed an atmosphere, it is remarkably tenuous. TRAPPIST-1 c, with a dayside temperature of approximately 380 […]
Space Telescope Science Institute’s Telescope Allocation Committee outlines the target selection procedure for the next cycle of Webb observations, sparking celebration among astronomers worldwide. What is the purpose of the peer-review process? “On May 10, the Space Telescope Science Institute (STScI), NASA’s James Webb Space Telescope’s science operations center, announced the scientific program for Cycle […]
Astronomers have identified an Earth-size exoplanet, or globe outside our solar system, that may be covered in volcanoes. The planet, known as LP 791-18 d, may have volcanic outbursts as frequently as Jupiter’s moon Io, our solar system’s most volcanically active body. NASA’s TESS, Spitzer Space Telescope, and an array of ground-based observatories were used […]
Another long-awaited scientific breakthrough has been made possible by NASA’s James Webb Space Telescope, this time for solar system scientists investigating the origins of Earth’s copious water. Astronomers have detected gas – especially water vapor – near a comet in the main asteroid belt for the first time using Webb’s NIRSpec (Near-Infrared Spectrograph), indicating that […]
