They are astronomers (天文学家) and they look at the stars. Other people design and make machines and these machines travel in space. Astronauts go up into space and look at the earth. They also take photos of the other planets and the stars. Sometimes they live in space for a few...
Astronomers seek to understand the nature, composition, behavior, and evolution of these objects, as well as the larger structure and dynamics of the universe. Astronomers employ a range of tools and methods to conduct their research. They use telescopes, both on the ground and in space, to ...

When astronomers measure how fast stars orbit the centers of galaxies, they find something strange. The stars at the edges of galaxies are moving much faster than they should be if only visible matter were present. This suggests that something unseen — dark matter — is adding to the galaxy...
From Martian winds to Saturn’s aurora, how sounds in space add to our understanding of the universe

Well. you might be right.According to a study published in Nature on June 23, astronomers have found that 1,715 stars have had a direct view of Earth since humans have been here.In order to do this, scientists used a previous method that looked for life on other planets. But instead,...
Astronomers arestill concernedabout how a megaconstellation like Starlink will change the sky. Radio astronomers recently warned that SpaceX's more powerful V2 satellites could alsoblind radio telescopes. But the economics of space are changing so rapidly that polite objections are getting steamrolled....

In 2017,astronomers observed for the first time gravitational waves, ripples in the very fabric of spacetime, and light that was sent radiating outwards from a collision between neutron stars. The signals that came from clashing binary neutron stars located 130 light-years away, verify the utility...
