Gamma-ray bursts (GRBs) are relatively rare astronomical events, with estimates suggesting that there are about 1 to 3 GRBs occurring in our galaxy each century. However, when considering the entire observable universe, it's estimated that there could be several hundred GRBs happening each year. Advances in detection technology allow astronomers to observe more of these events across vast distances, leading to better understanding of their frequency and distribution.

How long would it take gamma rays from an exploding star to reach earth?
Gamma rays are a form of electromagnetic radiation, and thus they travel at the speed of light. If a star is one light year away, it will reach Earth in one year.
When will the same calendar year happen again as 1955?
1955 was a common year starting on a Saturday. As of 2011, the next time this year will happen is in 2022.
How often do tornadoes happen in California?

Does the aphelion and the perihelion happen on the same days every year?
No, the aphelion (farthest point from the Sun) and perihelion (closest point to the Sun) do not happen on the same days every year. The Earth's orbit around the Sun is elliptical, so the dates of aphelion and perihelion shift slightly from year to year.
How many hot air balloon accidents happen every year?
On average, there are around 20 hot air balloon accidents reported worldwide each year. These accidents can vary in severity, from minor incidents to more serious crashes. Accidents are relatively rare considering the number of hot air balloon flights conducted each year.
How many gamma ray bursts would scientist detec in a week?
We actually only find a few a year.
What year did the astronomers find magnatars?
Magnetars were first identified in 1998 when astronomers discovered a new type of neutron star with an extremely strong magnetic field. The discovery was based on the observation of the soft gamma repeater SGR 1900+14, which exhibited bursts of gamma-ray emissions. This finding expanded our understanding of neutron stars and their magnetic properties.

What is the frequency of gamma waves?
Gamma rays are highly energetic rays emitted from nuclei of radioactive elements. Their frequency range is 3*1019 Hz (30 EHz) or higher. Exposure to large amounts of Gamma rays is harmful for health.
