Discover what exist in the universe
Historical Estimates of Universe Size In the early 20th century, the universe was thought to be infinite and unchanging, with Earth at its center. Astronomers like Harlow Shapley believed the Milky Way was essentially "the universe," stretching 300,000 light-years across. Edwin Hubble's 1929 measurements revealed a much larger universe, approximately […]
Current Understanding of the Universe's Size The vastness of the universe challenges scientists striving to measure its scale. While estimates have evolved, they still astound with their magnitude. Our ability to measure this boundless space relies on innovative technologies and theories that aim to define its enigmatic boundaries. The Hubble […]
Launch and Orbit The James Webb Space Telescope (JWST) launched on December 25, 2021, from Kourou, French Guiana, aboard an Ariane 5 rocket. It now orbits the second Lagrange point (L2), approximately 1.5 million kilometers from Earth. This position offers several advantages: From L2, JWST can peer far into the […]
Origins and Vision Elon Musk introduced the Hyperloop concept in 2013, envisioning pods transporting people and goods through low-pressure tubes at speeds approaching 1,200 km/h. This innovative idea aimed to revolutionize travel by drastically reducing journey times, such as traveling between San Francisco and Los Angeles in about 35 minutes. […]
Current Valuation and Growth Trajectory SpaceX's valuation has skyrocketed to an impressive $350 billion, showcasing the company's adept financial maneuvers and market strategies. This valuation surge stems from a strategic secondary stock sale, where SpaceX and investors agreed to purchase $1.25 billion worth of shares from insiders at $185 per […]
Solar Corona Observation Techniques Observing the solar corona presents unique challenges due to the sun's intense brightness. Researchers employ various methods to study this outermost layer of the sun, each with its own advantages and limitations. Total solar eclipses offer rare opportunities to view the corona in detail when the […]
Parker Solar Probe's Mission The Parker Solar Probe, launched by NASA in 2018, ventures closer to the sun than any previous human-made object. Its mission is to unravel solar mysteries, particularly the dynamics of solar flares. Encased in a cutting-edge heat shield, the spacecraft can withstand temperatures nearing 2,500 degrees […]
Thermal Protection System The Parker Solar Probe's Thermal Protection System (TPS) is an engineering marvel crafted from carbon-carbon composite. Sandwiched between two carbon sheets, this material shields against temperatures reaching nearly 2,500 degrees Fahrenheit. Despite its protective capabilities, the TPS remains relatively lightweight at 160 pounds. The sun-facing side features […]
NASA's Artemis II: Reigniting Lunar Exploration NASA's Artemis II mission aims to reignite humanity's fascination with the Moon. This crewed lunar expedition, the first since Apollo 17, will test critical systems for future lunar landings. Four astronauts will journey aboard the Orion spacecraft around the Moon and back, preparing for […]
Dark Matter and Universe Expansion Dark matter intrigues scientists with its enigmatic properties and significant role in cosmic events. Comprising about 84% of the universe's mass, dark matter remains undetectable through direct means like light or electromagnetic forces. Its existence is inferred from gravitational effects on ordinary matter, orchestrating the […]
