What radiation emitting from stars to earth?
All forms of electro-magnetic ... the full spectrum from UV to visible light to infrared.
Pulsars emit x-rays
What is the process in which the work of scientists is evaluated by the other researchers?
Peer Review!
Who is the well known scientist and what did he invent?
Isaac Newton -- invented calculus and a type of telescope that was more compact, but gave better magnification to see planets, stars, etc.
Why must an experiment be able to be conducted by scientist?
A theory is useless if it cannot be tested and verified/disproven. That is the purpose of experiments.
How do scientists replicate the work of other scientists?
Research results are published in scientific journals. If some scientist wishes to replicate the work of another scientist, he or she reads about it in the published report, and then does what the written description says.
When would scientist use estimate numbers?
Very often. Many physical constants cannot be determined exactly, only approximated. For calculations estimates are used for important mathematical constants, such as pi and e.
I would hazard a guess that no continuous physical measure is known accurately - unless by definition. It may be known to a very high degree of accuracy but measurement errors, random errors and, if nothing else, quantum effects will probably prevent perfect knowledge.
Second, total accuracy is often unnecessary. People on Answers.com often give answers to many decimal places - usually way beyond what can be justified. If you have the radius of a circle accurate to 3 siginificant figures and want to calculate the circumference, there is absolutely no point in using a value of pi that is accurate to a greater degree. Use the appropriate estimate and save yourself a lot of bother.
Why scientist uses beepers on bears?
It can be easily implanted under the bear"sskin after the animal has been tranquilized.
What kind of microscopes do scientists use to see very small objects?

Why do you think the work of scientist cannot be pinned down to a single year?
Do you think the contributions of these scientists are still valuable,even though some were made hundreds of years ago?Explain your answer.
Who was the first person to write about gravity?
The scientist who wrote about gravity and the laws of motion was Sir Isaac Newton.
Which characteristics do scientists to use to group species?
Scientists use Ancestors and DNA to group DNA.
Was Newton one of the most influential scientist of all time?
Yes, his discoveries and writing are basic material for every scientist to this date, so he basically influenced every scientist in the world.
Francis Drake :)
When did Johannes Kepler discovered the universe?
Nobody discovered the universe. We have always known that the universe exists. Discoveries of how the universe works and what it is have been made by many people.
What do scientists do after the reach conclusions from the results of their experiments?
They share the results of the experiment.
Why do the common names of organisms like daisy often cause problems for scientists?
They vary among languages and from place to place and different species may share a common name.
What does it mean for scientist to reject a hypothesis?
That he either found it to be incorrect or heard from a majority of other scientists working in the same field of study that the hypothesis isn't true. Though it's almost always the first one I said.
