Space science – field that encompasses all of the scientific disciplines that involve space exploration and study natural phenomena and physical bodies occurring in outer space, such as space medicine and astrobiology.

Jan 2, 2025 · Discover the universe: Learn about the history of the cosmos, what it’s made of, and so much more. Concentrations of matter with gravity so powerful not even light can escape. Collections of stars, planets, and vast clouds of gas and dust bound together by gravity. Worlds beyond our solar system.

Oct 29, 2024 · About 8,000 miles (12,800 kilometers) below your feet — on the opposite side of Earth — lurks the unforgiving vacuum and radiation of outer space. In fact, you’re technically in space right now. Humans say “out in space” as if it’s there and we’re here, as if Earth is separate from the rest of the universe.

Outer space (or simply space) is the expanse that exists beyond Earth's atmosphere and between celestial bodies. [1] . It contains ultra-low levels of particle densities, constituting a near-perfect vacuum [2] of predominantly hydrogen and helium plasma, permeated by electromagnetic radiation, cosmic rays, neutrinos, magnetic fields and dust.

Space research is scientific study carried out in outer space, and by studying outer space. From the use of space technology to the observable universe, space research is a wide research field. Earth science, materials science, biology, medicine, and …

In 2020, astronomers uncovered an enormous secret: A wave-shaped chain of gaseous clouds in our sun’s backyard, giving birth to clusters of stars along the spiral arm of the Milky Way. Researchers reported the first-ever sighting of a star engulfing—and obliterating—a planet, providing a preview of what could happen to Earth.

atmosphere and outer space. The line is neither sharp nor well defined but is often taken to encircle Earth at an altitude between 80 to 100 km (50 to 62 miles) above mean sea level. Read More
