But donât take over-the-counter (OTC) cough suppressants unless coughing keeps you up at night, Dr. Hanania advises. That's because, true to name, they suppress the cough â keeping the mucous in. If you take anything, âa mucolytic [which breaks down or thins mucous in the respiratory tract] may soothe the coughâ and make it more moist, he says.
Answer: It is not an easy thing to measure the distances to objects in the universe since these objects are usually very far away. We can't just run out there with a ruler! To measure distances in the universe, we will need to construct what is commonly referred to as a cosmic distance ladder.he links below will take you to descriptions of various common methods. 1  Radar-measuring distances in our solar system. 2  Parallax-measuring distances to nearby stars. 3  Cepheids-measuring distances in our Galaxy and to nearby galaxies.
Hint: A light-year is a unit of distance, not time. A light-year is how astronomers measure distance in space. Itâs defined by how far a beam of light travels in one year â a distance of six trillion miles.Think of it as the bigger, badder cousin of the inch, the mile, the kilometer, and the furlong.o light from a star at one end of our galaxy takes 20 times longer than all of recorded history to get to the other end. Astronomers measure the distance to the Andromeda galaxy using light-years. One light-year equals about 6 trillion miles. This galaxy is over 2 million light-years from Earth.
