2025年2月5日 · 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.

2024年10月29日 · 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.

2 天之前 · NASA Science seeks to discover the secrets of the universe, search for life elsewhere, and protect and improve life on Earth and in space. Our mission milestones showcase the breadth and depth of NASA science.

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.

2022年7月12日 · The five pictures from the most powerful space observatory ever launched offer a deep look back in time and the promise of stellar things to come

2025年1月31日 · Space telescopes like NASA’s Hubble and Webb have zoomed in on many corners of the universe to show us planets, stars, and galaxies in high resolution. ... (formerly Ball Aerospace) built the telescope and the spacecraft bus. The science analysis of the SPHEREx data will be conducted by a team of scientists located at 10 institutions in the U ...

2 天之前 · The mission will focus on massive regions of gas and dust called molecular clouds.Within those, SPHEREx will also look at some newly formed stars and the disks of material around them from which new planets are born. Although space telescopes such as NASA’s James Webb and retired Spitzer have detected water, carbon dioxide, carbon monoxide, and other compounds in hundreds of targets, the ...

3 天之前 · Although space telescopes such as NASA’s James Webb and retired Spitzer have detected water, carbon dioxide, carbon monoxide, and other compounds in hundreds of targets, the SPHEREx observatory is the first to be uniquely equipped to conduct a large-scale survey of the galaxy in search of water ice and other frozen compounds.. Rather than taking 2D images of a target like a star, SPHEREx ...

6 天之前 · SPHEREx will look into deep space and also search for organic molecules. NPR Science. ... "it's going to be really useful to a whole host of different science questions and opportunities."

2023年1月11日 · Researchers confirmed an exoplanet, a planet that orbits another star, using NASA’s James Webb Space Telescope for the first time. Formally classified as LHS 475 b, the planet is almost exactly the same size as our own, clocking in at 99% of Earth’s diameter.
