We have a top 10 guide here to help you get started with making your selections. There are many, many accessories and it can be easy to feel overwhelmed at first. The next thing you should get to know about your telescope is its accessories. To learn more about the different types, and if you're wondering which one you have, check out our blog on the different types of telescopes! There are three main types, refractor, reflector, and catadioptric. Parts of a TelescopeĮach part of the telescope works together to function as a powerful observing system. Check out this chart below that visually defines the pieces of a telescope for you. This guide will walk you through all the parts of your telescope and provide tips to maximize your stargazing experience!īefore we get into the more technical parts of your telescope, let’s review the main pieces first. ![]() In this image, which captured light in the visible wavelength range, a bright swirl of material from the prominence trails the fainter edge of the coronal mass ejection as the two plunge into space.Welcome to the hobby! Using your telescope for the first time is an exciting first step into exploring the universe. "It's generally accepted, though still not conclusively proven, that prominence eruptions occur when the overlying magnetic field that contains the prominence material is disrupted," he said.Īnother image showing the same coronal mass ejection and prominence eruption was captured by the Solar and Heliospheric Observatory on Monday. According to Gurman, the first event was probably an outburst of the sun's magnetic field called a coronal mass ejection. In the image sequence, there is a burst of activity around the prominence, and then it and the filament channel shoot out into space immediately afterward. "The absorption is typically seen in lines such as Fe XIV only in the thinnest, densest parts of the prominence, which is here seen edge-on as it rotates over the solar limb," he said. ![]() The dark filament seen in the images (the refueling UFO's "tether," according to YouTube users) is a part of the prominence that happens to absorb light of this color, making it appear dark. He added that the development of these structures is quite common.īut why is the prominence dark? Gurman explained that all the light in the SDO images is the same color - a specific wavelength that is emitted by iron atoms that have been ionized 13 times, known as Fe XIV. ![]() And this tunnel sits up top of the filament," Young explained at The Sun Today. "When you look at it from the edge of the sun, what you actually see is a spherical object. Alex Young, a solar astrophysicist at NASA's Goddard Space Flight Center who runs a website called The Sun Today, explained that the prominence is situated below a tunnel-shape feature called a filament channel. "When prominences are that extended in height above the limb (edge of the sun), it's usually a sign that they're about to erupt, as this one did," Gurman told Life's Little Mysteries.Ĭ. It isn't yet known exactly how prominences develop, but these dense plasma loops can extend from the sun's surface thousands of miles into space. The thread extending from the lower left edge of the sun in the video is known as a "prominence," a feature containing cooler, denser plasma than the surrounding 3.5 million-degree Fahrenheit corona, said Joseph Gurman, project scientist in the Solar Physics Laboratory at NASA Goddard. However, according to NASA scientists, the feature is actually a little-understood, but frequently observed, type of solar activity called a "prominence," and the way it is situated beneath another solar feature gives it its otherworldly appearance.
