Ordinary light photographs are taken with a camera attached to the telescope, often using exposure times of many hours long to collect as much light as possible. In fact almost all astronomical observations are done this way, it is very rare for humans to use the telescope directly anymore.
Radio telescope photographs are taken by feeding the signals to a computer which generates synthetic false colorimages.
X-ray and gamma ray telescope photographs use a camera like ordinary light telescopes, but as these signals cannot pass through earth's atmosphere the must be done from orbiting satellites. These images are also frequently post processed by computer to add false colors.

Explain how all galaxies are similar?
All galaxies are massive clusters of stars scattered across the universe. Many galaxies take the same form, for instance, spiral and elliptical galaxies. Some galaxies also have a black hole in their center.

When galaxies collideno spectacular explosions take placethe two galaxies simply pass through each otherexplain why this is so?
A galaxy is 99.999% empty space; they aren't actually solid. The only time you would see a "spectacular explosion" would be if individual stars within the galaxies were to collide. Which isn't to say that they would pass right through each other; the one thing each galaxy does have is what keeps it together as a galaxy; gravity. When two galaxies collide (which apparently is not particularly uncommon; we have photos of several sets of galaxies that are even now in the middle of their own collisions) each star within the galaxies falls under the gravitational influence of not only the other stars in their own galaxy but also all the gravity of all the stars in the other galaxy. The stars are bent away from their normal paths, each deflecting the other, until they swirl together - or are flung away from the galaxy and into deep space. In fact, many astronomers claim to have identified the traces of at least a few other galaxies within our own; the Milky Way has apparently swallowed some other galaxies.
How long does it take to the end of the galaxy?
Galaxies don't really end or disappear. Stars can take a few billion years to die, but it's all part of a cycle that feeds new stars. The black hole in the center could suck up all the stars if something were to throw them out of orbit. A collision of two galaxies is unlikely, but it happens, and if it did, many stars would be flung into space. But 1 galaxy would be formed as a galactic sandwich.
Why cameras not allowed inside the electronic bingo?
Because people can take photos of who one and they can also take photos of the number that person had on her card.
Why do photos showing astronauts in space never show any stars.?
Most regular cameras will not pick up stars when you take a photograph. It takes more specialised cameras that are capable of taking in a lot more light and often doing long exposures to get good photographs of stars. The cameras used to take photos of the astronauts in space are more basic types of cameras, so they don't show stars.
How to get start right in astronomy?
Astronomy is the study of the stars and galaxies. To start learning about astronomy take a college class or check out books from your local library.
What is a basic building block of galaxies?
I am not sure there is one. Galaxies contain stars, gas, dust, black holes and other dead stars, and - above all - dark matter. The dark matter typically makes up 80-90% of a galaxy's mass.
How has the development of cameras helped people today?
You can take faster photos.
What does the Hubble space telescope take pictures of?
The Hubble Space Telescope takes pictures of various celestial objects in space, including stars, galaxies, nebulae, and planets in our own solar system. It has provided stunning images that have helped astronomers better understand the universe and phenomena like black holes, distant galaxies, and planetary atmospheres.
Why are cameras useful in astronomy?
Cameras are useful in astronomy because they can capture images of distant celestial objects with high sensitivity and accuracy. This allows astronomers to study and analyze these images to learn more about the universe, such as identifying different types of stars, galaxies, and other astronomical phenomena. Cameras also help in recording data for long-term observation and research.
What was Katie's first job?
her first job was to model for people to take photos.
