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)氣體云自星際物質(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)于信號(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)星升空的時(shí)候，我還在上中學(xué)；在我的一生當(dāng)中，我們研制的飛行器飛行能力從剛剛高于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.
