Random Space Facts. In recent decades, the 300+ year old Great Red Spot has been slowly dying down. Yuri Gagarin was the first human to enter space. The only planet that rotates clockwise is Venus. The odds of being killed by fallen space debris are 1 in 5 billion.
Space is a three-dimensional continuum containing positions and directions. [ 1] In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. [ 2]
Being essentially empty, outer space allows the earliest (redder) galaxies to be viewed without obstruction, as in the Webb's First Deep Field image. Outer space (or simply space) is the expanse that exists beyond Earth's atmosphere and between celestial bodies. [1]
Space exploration is the use of astronomy and space technology to explore outer space. [1] While the exploration of space is currently carried out mainly by astronomers with telescopes, its physical exploration is conducted both by uncrewed robotic space probes and human spaceflight.
Outer space, or simply space, is the void that exists between celestial bodies, including the Earth. It is not completely empty, but consists of a hard vacuum containing a low density of particles: predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, and neutrinos.
Outer space, commonly shortened to space, is the near-vacuum between celestial bodies. [1] It is where all of the planets, stars, galaxies and objects are found. It is the expanse that exists beyond Earth and its atmosphere. On Earth, space begins at the Kármán line (100 km above sea level). [2]
A spacecraft is a vehicle that is designed to fly and operate in outer space. [ 1] . Spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo.
The Space Age is a period encompassing the activities related to the space race, space exploration, space technology, and the cultural developments influenced by these events, beginning with the launch of Sputnik 1 on October 4, 1957, [1] and continuing to the present.
The James Webb Space Telescope is a giant leap forward in our quest to understand the Universe and our origins. Webb is examining every phase of cosmic history: from the first luminous glows after the Big Bang to the formation of galaxies, stars, and planets to the evolution of our own solar system.
Aug 9, 2024 · Space exploration, investigation, by means of crewed and uncrewed spacecraft, of the reaches of the universe beyond Earth’s atmosphere and the use of the information so gained to increase knowledge of the cosmos and benefit humanity.
