The system of stars that includes our sun looks, in the night sky, like a broad band of light. We call this band the Milky Way. The idea of the whiteness of the Milky Way being similar to that of milk is much older than the English language, however. Galaxias, the Greek word for ...
TheJames Webb Space Telescope(JWST) has found a galaxy in the early universe that's so massive, it shouldn't exist, posing a "significant challenge" to the standard model of cosmology, according to the study authors. The galaxy, called ZF-UDS-7329, contains more stars than theMilky Way, ...
have shown that there are no stars in the solar neighbourhood and no galactic clusters whatsoever that are older than the globular clusters. This is an indication that globular clusters, and thus Population II objects, formed first in the Galaxy and that Population I stars have been forming sinc...
Universe contains something like 125 billion galaxies, but the Universe is much bigger than that part which we can ever see! The picture above shows a (type Sa) spiral galaxy in plan view (rendered using Steve Colefax'sGalaxy.incfor Pov-Ray). The density of stars increases toward the galac...
Rather than being randomly distributed, each part of the galaxy has a distinct location or home. Within our galaxy are clusters of stars. Some clusters contain older stars while others contain young stars. Where they are tells us about the age and formation of our galaxy. Some parts of the...
第二段提到“ While the new telescope has spotted even older galaxies, dating to within 300 million years of the beginning of the universe, it's the size of these six galaxies that shock the researchers.”可知,这六个星系的大小尺寸是其 特别之处,因此让研究人员震惊。 故选C。 5.D 解析:词义...
These galaxies contain much older stars than the picturesque spiral galaxies and are held together by the force of gravity. Another galaxy, NGC 1427A, is in the lower left corner of the image. This irregular galaxy is moving toward the heart of the cluster at high speed and will eventually...
The game is afoot! Astronomers may have found some of the universe’s missing matter, thanks to one team’s cosmic detective work.The case has been open for more than 20 years. In the 1990s and early 2000s, scientists sleuthed out the universe’s conten... ...
The most distant galaxies detected were seen when the Universe was a scant 5% of its current age. At these times, progenitors of galaxies such as the Milky Way were about 10,000 times less massive. Using the James Webb Space Telescope (JWST) combined wit
Astronomers Have Recorded the Biggest Explosion Ever Seen in the Universe Hundreds of millions of light years away, a supermassive black hole sits in the center of a galaxy cluster namedOphiuchus. Though black holes are renowned for sucking in surrounding material, they sometimes expel material in ...
