The Northern Lights

One of the world’s most fascinating and natural wonders are the Northern Lights. These magical lights come in a variety of dancing colors. This seemingly random light show occurs as a result of interactions of Earth’s magnetic field and atmosphere with solar winds. Solar winds released by the Sun’s sunspot regions travel through space until they meet with Earth’s magnetosphere. Usually, the magnetic field is strong enough to block these winds, but near the poles, it is weak enough to be penetrated by the solar winds. The solar winds collide with Earth’s atmosphere and create the beautiful lights that we’ve come to admire.

Telescopes

Digital Trends

Telescopes have been an essential instrument in the history of astronomy. So much has been learned and will be learned through the use of them. Although, they all have the same general function, telescopes can come in many shapes, sizes, and types. The two main types of telescopes are the refractor and reflecting telescopes. In a refactor telescope, a piece of glass known as the objective lens gathers light and focuses it onto the eyepiece lens, which enlarges the image for our eye to see. Galileo used this type of telescope to see the moons of Jupiter and the phases of Venus. On the other hand, a reflector telescope has two mirrors rather than the refractor’s two lens. One curved mirror reflects the incoming light from a distant object onto a tiny, flat mirror which in turn reflects the light to the eyepiece. Isaac Newton is credited for inventing the reflecting telescope. Reflecting telescopes are the most popular telescopes used for research purposes.
