If we consider the bursts of high energy electromagnetic radiation from stellar or galactic sources, we encounter bursts of X-rays and gamma rays. The two are similar in that both are examples of high energy electromagnetic energy, and both can be generated by certain stars or galaxies. Additionally, both are the result of nuclear reactions in the star or at sites within the galaxy. But with gamma rays, the sources may be fewer than with X-rays, and the gamma rays are higher in energy than the X-rays.
Yes, but not to any usable amount. The amount of energy that comes from gamma rays bursts are, by the time they reach here, quite small. The INTENSITY of the bursts may be large, but they don't last very long. Also, they come from outside our galaxy, so they have lost most of their energy by the time they get to us. And the direction they arrive from is impossible to predict, so any collector would be impossible to aim for maximum efficiency. If a ten meter by ten meter collector was 100% efficient in converting gamma ray energy into electricity, and was able to collect enough energy from gamma rays to power a 100 watt light bulb for ten minutes; the amount of gamma ray energy hitting our Earth would kill all humanity in less than a week. In a sense, it is a blessing that there is not a lot of gamma ray energy reaching us!
You can't. Gamma can pass through several feet of steel. For each inch of steel gamma rays are attenuated by 50%. Normal mirrors and lenses have no effect on gamma.
I presume you mean a "gamma ray burst." This is a burst of gamma ray energy, lasting from less than a second to a few minutes, that comes from outside our galaxy. Despite being from that far away, they are measurable on our planet, meaning the energy release in one second of a gamma ray burst is greater than the energy that our Sun will release in its entire ten billion year life cycle. GRB's are now thought to be from the collapse of a massive star, but the question has not been completely settled. If a gamma ray burst from within our galaxy were to hit our Earth, all life on our planet, even bacteria, would end within a few days.
Yes, it is believed that gamma rays were present during the early stages of the Big Bang, produced as a result of high-energy processes. However, the extreme conditions of the early universe make it impossible to directly observe these gamma rays.
If a gamma ray burst hit Earth, it could potentially strip away the ozone layer, leading to an increase in harmful ultraviolet radiation from the sun. This could have catastrophic effects on the environment and life on Earth. However, the likelihood of a gamma ray burst hitting Earth directly is very low.

The answer depends on what you wish to compare and contrast it with.
The moods of the speakers are different, and you would contrast them in a compare-and-contrast.
You would use a pie chart to compare and contrast information.

We actually only find a few a year.
A bar graph would be the best graph or chart to use to compare and contrast information.

When a star goes supernova it releases a bursts of energy (which is also radioactive) that shoot out from the core. Gamma ray bursts have intense radiation and travel so quickly that if one were to hit earth we would get no warning until it hit us and everything would be vaporized. There is a dying star close to earth and right now at any moment it could go supernova and the worst part is its release of energy is aimed right at us. Gamma ray bursts also form when 2 neutron stars collide or when a neutron star collides with a black hole.
Earth gets hit every day by gamma-ray bursts - from far, far away. Depending on how near the gamma-ray burst is, it may cause some serious damage.
It's hard to contrast and compare when I just don't have the words.
