This extensively illustrated book presents the astrophysics of galaxies since their beginnings in the early Universe. It has been thoroughly revised to take into account the most recent observational data, and recent discoveries such as dark energy. There are new sections on galaxy clusters, gamma ra...
space between the galaxies in our universe was a near- perfect vacuum. This orthodox view of the universe is now being challenged by astronomers who believe that a (5) heavy“rain” of gas is falling into many galaxies from the supposedly empty space around them. The gas apparently condense...

But it is not special, it's one of the common galaxies in the universe可知,银河系是宇宙中一个普通的星系。 5. 根据第二段的Now, new measurements show that our Milky Way galaxy is bigger than scientists once thought以及相关内容介绍可知,文章主要是谈银河系比科学家想象的要大。
根据"IRREGULAR GALAXIES: There are many other shapes of galaxies that aren't spiral or elliptical. They all fit into the irregular category. They are smaller than spiral galaxies. "可知既不是螺旋形状也不是椭圆形状的都属于不规则星系,不规则星系比螺旋星系小。根据大小可知A项错误,B项一个长而窄,...
The article focuses on how the radio Square Kilometre Array telescope project aims to solve how the first galaxies in the universe formed. Topics discussed include the goal of building the most sensitive radio telescope that ...
This book provides a comprehensive, self-contained introduction to one of the most exciting frontiers in astrophysics today: the quest to understand how the oldest and most distant galaxies in our universe first formed. Until now, most research on this question has been theoretical, but the next...
“While some of the galaxies are nearby, most are very distant; we even found galaxies that are so far that their light has taken 12 billion years to travel here, so we are seeing them when the Universe was only a ninth of its current age,” said Dr. Caitlin Casey, Hubble fellow at...
