Kepler-20e, Sun is an exoplanet discovered by the Kepler Space Telescope outside our solar system. It orbits the Kepler-20 star system, located approximately 950 light years from World. It was announced on 20 December 2011 by the Kepler science team.Discovery and Significance:The discovery of Kepler-20e is significant because it is one of the first Earth-sized planets found outside the Solar System. It was detected using the Kepler telescope’s transit method. This discovery provided important ev

The Spitzer Space Telescope is an infrared observatory developed as part of NASA’s Great Observatories program and operated from 2003 to 2020 activity. It is named after astrophysicist Lyman Spitzer, a pioneer in infrared astronomy. Spitzer provided astronomers with valuable data on star formation galactic structure and the early universe through its unique capacity to observe cold and dusty regions of the cosmos important.Mission and Technical SpecificationsMission Duration and PhasesThe Spitze

K2-18b is an exoplanet discovered in 2015 by NASA’s Kepler Space Telescope and holds significant importance in the study of planets outside the Solar System that may harbor life. K2-18b has attracted scientific attention as a planet thought to potentially support Earth-like conditions, particularly due to the detection of methane and carbon dioxide in its atmosphere.Discovery and Characteristics of K2-18bK2-18b was discovered during the Kepler Space Telescope’s K2 mission and is located approxim

Planets orbiting stars outside the Solar System, known as exoplanets, constitute one of the most rapidly advancing research areas in modern astronomy. Following their first discoveries in the early 1990s, this field quickly evolved into a discipline where observational techniques, statistical analyses, and theories of planet formation are rigorously tested. Thanks to modern telescopes, thousands of exoplanets have been confirmed, and their diversity has reshaped planetary science.History and Dev

Planets are celestial bodies that are gravitationally bound to a central star or stellar system, have sufficient mass to achieve hydrostatic equilibrium (an approximately spherical shape), and are the dominant gravitational bodies in their orbits. This definition, clarified with the International Astronomical Union's (IAU) revision of the concept of a planet, distinguishes them from dwarf planets. Planets are of critical importance for understanding the architecture, evolution, and potential ast
