Gamma rays burst very brightly and at high energies.
Gamma rays are high energy, but relatively slow burning. Gamma rays are an essential part of the spectrum of radiation that makes up the sun. In gamma-ray astronomy, gamma rays are highly energetic explosions which have so far been discovered in distant celestial bodies.
Gamma-rays come from exploding stars, supernovae, and other stellar explosions.
They are perhaps the most energetic and brightest electromagnetic events known to happen in the universe. Bursts may last from a few seconds to a few hours. The bursts usually do not destroy the surrounding matter, but can significantly heat and/or vaporize material near the burst point. The burst can, in some cases, create gamma rays that may reach and possibly destroy Earth.
These cosmic explosions are extremely hazardous.
While it is not impossible for some of these bursts to reach the earth, they are so bright that it would be extremely dangerous. Luckily, many natural disasters and human activities prevent most of these occurrences. But humans can occasionally be affected by gamma rays. In the case of terrestrial gamma-rays, people who work with gamma rays in the workplace should keep themselves well protected. These people could be struck by illness or death if exposed.
Astronomy is a wonderful subject and field of study for gamma ray bursts.
It has allowed us to explore other worlds in the solar system, in space, and even in other galaxies. Through telescopes, we have seen other planets in our solar system and other stars and solar systems. Astronomy has also allowed us to track the evolution of our planet and learn more about its early formation.
Gamma-Ray bursts occur when a dying white dwarf star, called a propeller mass, emits gamma rays in a collision. If these collisions occur frequently enough, these distressing events may cause the death of a small portion of the matter within a planet or satellite. This phenomenon is known as a Planet X impact and is occurring frequently in collisions between compact comets and smaller solar system bodies. A gamma ray burst observed recently in our galaxy is believed to be caused by binary neutron stars.
The duration of a gamma ray burst depends on the energy output of the system.
At high energies, the duration can be very short, while at lower energies, the burst can last as long as a year. It has been calculated that such short duration gamma bursts occur every ten million years. The longer duration gamma emission events may have longer wavelength components, but the interval within which they happen is much shorter – about one hundred million years.
Studies of gamma-ray bursts show that they are produced by extremely compact gas clouds. These clouds are thought to be being pushed out from the central region of the Milky Way galaxy by winds. The recent study also suggests that these clouds are being pushed away by a companion galaxy, which is why we only see gamma-rays emanating from a compact object that is relatively nearby. Compact gamma-rays originate from a companion galaxy to a very distant elliptical galaxy and are therefore faint. Although the gamma-rays originate from a cloud in the Milky Way, the study finds that the cloud is moving at a great distance away.
Studying gamma-rays as they exit a star can be done using a variety of methods.
Radio telescopes like the European Southern Observatory use Very Long Baseline Transients (VLBT), Very Large Array (VLA), and others to detect these emissions. Astronomers using Chandra, Gemini, and radio observatories like Arecibo and Radio France/ESA use Very Long Baseline Interferometer (VLBI) to detect these emissions.
