天文學概論:宇宙的起源與歸宿 前言 回大綱 宇宙中有上千億的星系,平均每一星系又約有上千億的恆星及各類天體。相對的,天文學家也有較多的"樣品" ,可以拼湊出有關恆星與星系的完整理論。但是我們只有一個宇宙,建構一個合理的宇宙論並不容易,所以宇宙論標準模型 大爆炸 ...
臺大天文研究所 - 國立臺灣大學物理學系 天文物理可以說是人文氣息最為豐富之自然科學領域,也可以說是人類基於對宇宙與大自然之好奇衍生出來之最古老的科學。人類文明之源起,也可能肇始於我們老祖先對於天象之震懾、恐懼、與進一步之嘗試理解。

Cosmic microwave background - Wikipedia, the free encyclopedia The cosmic microwave background (CMB) is the thermal radiation assumed to be left over from the "Big Bang" of cosmology. In older literature, the CMB is also variously known as cosmic microwave background radiation (CMBR) or "relic radiation." The CMB is
Cosmic Background Explorer - Official Site The COBE satellite was developed by NASA's Goddard Space Flight Center to measure the diffuse infrared and microwave radiation from the early universe to the limits set by our astrophysical environment. It was launched November 18, 1989 and carried three
