Light Observations

Warehouses, container lots, pipeline yards, and exterior lights were inspected from 1800 to 2200 on Thursday February 2 to 5. After searching all the fixtures outside the warehouse, only two were found to be dangerous for someone. The first thing I found was Hatch 1A - 1, the clamps were off the wall and the wires were exposed. 2B-2 is another place where danger may exist.

For the first time, due to the Northern Light observation of NASA's mission, scientists directly mapped the changing magnetic field of the Earth and generated the auroral current. The spectacular aurora has attracted thousands of people, but its essence - the fact that light is electromagnetic and reacts to solar activity - has only been realized in the past 150 years. Through cooperation between multi-satellite observations and global magnetic sensors and camera networks, close cooperation on aurora has become possible in recent decades. However, the aurora is enigmatic and continues dancing away from the ground, so far, several unknown rhythms

We observed a very violent process. As we see thunder and thunder in the storm, the embrace of neutron stars can be observed through light and gravity. Short pulse gamma rays (very high energy light) from distant galaxies have been discovered for decades, but their origins are elusive yet. "This event is different as it is caused by the collapse of a neutron star." The two objects are as heavy as the sun, but as small as the city, the light generated by the huge stars consuming that fuel will escape A spectacular explosion was seen from the distant universe due to the collision of neutron stars.

A gravitational lens is the distribution of matter between a remote light source and an observer (eg, a galaxy), and the light from the light source bends as it travels toward the viewer. This effect is called a gravitational lens and the amount of bending is one of predictions of Albert Einstein's general relativity. The gravitational lens also functions in the same way, and is the effect of Einstein's general relativity - in short, the mass bends the light. The gravitational field of a huge object expands into the universe, bending the light back to another place by approaching that object (and its gravity field) and refocusing again. The larger the object, the stronger the gravitational field, so the curvature of the light becomes larger and more refractive index is generated so that the higher density material is used to make the optical lens.
