The Universe:
The Universe is approximately 93 billion light-years in diameter (Fact 1). It’s estimated to be around 13.8 billion years old (Fact 2). The Universe is composed of approximately 70% dark energy, 27% dark matter, and 3% ordinary matter (Fact. 3). The Universe is expanding at an accelerating rate (Fact. 4).
Stars and Galaxies:
Stars: are huge celestial bodies composed mostly of hydrogen and helium, producing light and heat through nuclear fusion (Fact. 5).
Galaxies:, massive systems containing millions to billions of stars, gas, dust, and dark matter (Fact. 6).
The Solar System:
Our Solar System consists of the Sun, eight planets, and various moons, asteroids, and comets (Fact. 7). The planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune (Fact. 8). We have over 200 known natural satellites in our solar system (Fact. 9).
Earth and Atmosphere:
The Earth is approximately 12,742 kilometers in diameter (Fact. 10). The Earth’s atmosphere is mainly composed of nitrogen (78%) and oxygen (21%), with trace amounts of other gases (Fact. 11).
Space Travel:
Milestones include the first satellite (Sputnik 1), first human in space (Yuri Gagarin), and the first manned moon landing (Apollo 11) (Fact. 12). Major space agencies include NASA (USA), ESA (Europe), Roscosmos (Russia), JAXA (Japan), ISRO (India), and CSA (Canada) (Fact. 13).
Extraterrestrial Life:
The search for life beyond Earth focuses on planets like Mars, Europa, Enceladus, and Titan (Fact. 14). Hypotheses include Panspermia, directed panspermia, and the extrusion hypothesis (Fact. 15).
The Cosmos’ Wonders:
Black Holes: are celestial objects with immense gravitational pull, bending the fabric of spacetime (Fact. 16).
Quasars: are extremely bright and distant objects believed to be the active cores of galaxies (Fact. 17).
Neutron Stars: are dense remnants of massive stars, comprised mainly of neutrons (Fact. 18).
Supernovae: are explosive deaths of stars, producing various elements and shining brightly in the night sky (Fact. 19).
Planetary Rings: are a belt of particles orbiting a planet, such as Saturn’s iconic rings (Fact. 20).
Space Debris and Space Junk:
Originate from derelict spacecraft, discarded rocket stages, and fragments from explosions (Fact. 21). Threaten operational spacecraft and endanger human life and missions (Fact. 22).
Space Exploration and Future Missions:
Planned missions include the Artemis Program, Mars Sample Return, Europa Clipper, and the James Webb Space Telescope (Fact. 23). Goals include establishing permanent human presence on the Moon, Mars exploration, and space tourism (Fact. 24).
Space Telescopes:
The Hubble Space Telescope, launched in 1990, provided revolutionary discoveries about the Universe (Fact. 25). Spitzer Space Telescope observes distant celestial bodies and galaxies through infrared (Fact. 26). The Kepler Space Telescope discovered over 2,600 confirmed exoplanets (Fact. 27).
Astronomy Branches and Instruments:
Optical astronomy: studies celestial bodies using visible light (Fact. 28). Radio astronomy: detects and studies radio waves emitted by celestial bodies (Fact. 29). Spectroscopy: analyzes light to determine the physical properties of celestial objects (Fact. 30).
Space Technology:
Satellites: are used for communication, navigation, weather forecasting, and Earth observation (Fact. 31). Space probes: explore other planets, moons, asteroids, comets, and interplanetary space (Fact. 32).
