Also, the particle storms may stop some satellites(卫星) from working, so they may bring trouble to the BDS on our smartphones.()1. What do we know about the small particles from the sun? A. They are everywhere in space. B. The earth's magnetic field changes their movement. C. ...
Scientists use satellites and telescopes in space to see the high-energy light .(1)The gravity of a black hole may become so strong that light cannot get out when A. the star is going to die B. special tools are used on it C. other stars come close to it D. it is seen from ...
It turns out that planetary systems in our galaxy exhibit remarkable diversity—some have tightly packed planets in exotic configurations; others are dominated by gas giants skimming their stars. Now a new era of planetary science has emerged:exoplanet demographics. By analyzing patterns in the sizes...

1.Unless you're lucky enough to have the lights come to you, seeing auroras is a matter of being in the right place at the right time. Fortunately, we can forecast where and when they are likely to become visible, so you can increase your odds. Being in Norway between late September ...

B. The particles travel in space like a wind. C. Auroras come about because of the special activities of the sun. D. When the“wind" is strong enough, the auroras can cover larger areas. E. Also, the particle storms may stop some satellites(卫星) from working. ...
Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space shuttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there. 1. What was the ...
TheInternational Space Station(ISS) orbits Earth at an average altitude of 248 miles (400 kilometers) and Low Earth-orbitingsatellitesremain at altitudes ofless than 620 miles(1,000 km). With the space boundary at this new height of 6,000 miles (10,000 km), most of our Earth-orbiting ...
Edges are things that divide one region from another. But if the universe consists of all regions, there can't be an edge. This means the universe might be infinitely big, and it's impossible to point to the center of an infinite space. Get the Space.com Newsletter Breaking space news,...
