What else can I help you with?
What kind of electromagnetic radiation do you get at night?
Pretty much the same kinds you get during the day. The big difference between day and night is the Sun, which is a star; other stars give off the same kind of radiation the Sun does (a bit less here, a bit more there, and much less intense because they're further away, but still: the same kind).
In the stable a stars diameter and radiation?
remain the same... :)
Are the stars dangerous in space?
They can be. Stars are very hot and can emit harmful amounts of radiation. At the same time, without stars there would be no life.
Do all objects give out the same amount of heat radiation?
No, all objects do not give out the same amount of heat radiation. The amount of heat radiation emitted by an object depends on its temperature and its surface area. Objects at higher temperatures emit more heat radiation than those at lower temperatures.
What is the name to neutron stars that give off pulses of radio waves?
A pulsar is a special kind of neutron star, which is the ultra-dense leftover core of a massive star. Pulsars emit beams of radiation that sweep out in circles as the pulsar spins. When those beams flash over Earth, we see them as regular, repeating pulses of radio emission.
Can the mobile phone really damage your private part if you have it in your pocket?
No, absolutely not. The phone emits radiation -- but not the bad kind. It emits the same kind of radiation as your flashlight or radio, it's not going to damage anything. The "bad kind" of radiation (ionizing radiation) can damage your "private part", but there's none of it in your phone.
What telescope uses an antenna and receiver to study the stars?
A radio telescope has an antenna and a receiver to study the stars. Radio waves are part of the same radiation spectrum as light, and they are emitted by many celestial bodies. Analysis of radio emissions can give us information over and above what can be obtained from light.

Why isn't nuclear waste have its radiation used for solar power?
Because nuclear waste doesn't give off the same radiation as the sun.
Is beta the same kind of radiation as alpha but does not have particles?
No Alpha radiation is essentially a helium nucleus - a couple of protons and neutrons bound together as a particle Beta radiation is an electron or positron - still a particle but not the same kind of particle as alpha.
How come you can see the stars?
Stars give out light energy, that is they are luminous. Thus we see them for the same reason we see a lighted torch bulb.
What a star's diameter and radiation?
Both a star's diameter and its radiation vary widely from one star to another. Look at the data for our Sun, for an example - but consider that this is not exactly typical, in the sense that other stars can be much bigger or smaller, and radiate much more, or much less, energy, than our Sun.
