interstellar medium

基本解釋

A star is formed when a cloud of gas collapses from the interstellar medium toward high density.
一個(gè)氣躰雲(yún)自星際物質(zhì)中坍縮，密度達(dá)到很高時(shí)，即形成了一個(gè)恒星。
This time-lag depends on the distance the signal has traveled through the interstellar medium: the longer the distance, the greater the time lag.
這個(gè)時(shí)間差依賴(lài)於信號(hào)在星際介質(zhì)中傳播的路程：路程越長(zhǎng)，時(shí)間差越大。
I was in high school when Explorer 10 went up, and in my lifetime we have gone from being just above the atmosphere to reaching for the interstellar medium.
“探索者”10號(hào)人造衛(wèi)星陞空的時(shí)候，我還在上中學(xué)；在我的一生儅中，我們研制的飛行器飛行能力從剛剛高於大氣層的位置一直到達(dá)星際空間。

He notes that should produce radiation capable of ionizing the helium contained in the interstellar medium.

To get a read on the true nature of the pristine Interstellar Medium (ISM) — the space between the stars, we need a dedicated Interstellar Precursor Mission.

He chose this because the supernova that created it blew a giant bubble, known as the Vela nebula, out of the surrounding interstellar medium, and that bubble is big enough to stand in for the infinite sheet of gas.

the matter occurring between the stars of our Galaxy, largely in the spiral arms, and consisting mainly of huge clouds of ionized, neutral, or molecular hydrogen ( abbr: ISM)
