Astronomers use many telescopes to see different things in the universe. Radio telescopes detect long wavelength light and investigate diverse things. X-ray and gamma ray telescopes detect very short wavelength of light and look at the sun, stars and supernovas. Reflecting telescopes see visible li...
Modern USB condenser mics have this feature: you can select a particular pattern by simply flicking a switch or changing the head of the microphone. Obivously, the biggest benefit of this type of mic is that you get to test the quality of sound in various conditions at affordable price. W...
Many examples of this type of photography include portraiture and fashion but can also require knowledge of other sub-genres such as still life, food, and architecture. Usually, the photographer would work with an editor of the publication that would direct them as to what type of images are ...

Only a few months after that discovery, astronomers also found a group of galaxies that were orbiting in sync with each other in a pattern that may be explained by dark matter. But in 2018, a group of researchers challenged the dark matter theory when they discovered that a galaxy called ...
Astronomers use all kinds of telescopes—some on Earth, some in space—to glean information about distant objects from the electromagnetic radiation they give off. Radio waves Giant satellite-dish antennas pick up long-wavelength, high-frequency radio waves. The biggest radio telescope on Earth is ...
New types of stars, including ‘old smokers’ and erupting protostars, have been discovered in the Milky Way. This research, using advanced telescopes, challenges existing theories on stellar life cycles and element distribution in space. ‘Hidden’ stars including a new type of elderly g...
And these are just the things that we can see from the surface of the earth by telescopes (望远镜). There are also millions of smaller pieces of junk that we can’t see. Objects, like bits of old space rockets or satellites, move around the planet at very high speedsfasts that even ...
Camouflaging is mainly of five types: 1. Background matching 2. Disruptive colouration3. Self-decoration4. Active camouflage 5. DisguiseAll form of camouflage has already been explained in the above posts. Here I am giving some more examples of camouflaging animals:a. Golde...
