COmet McNaught has been a brilliant, beautiful secret since 2007, when researchers at the Washington-based marine research laboratory (D.C.) watched a satellite imagery. The land that first saw the comet was influenced by its brightness and strange configuration. It was not only so bright that it was visible during the day from some parts of the Earth, but it was also sided several long, peacock-like tail.
It is believed that these tails are important indications of how planets and satellites were formed billions of years ago, but for years they did not have all the tools to further analyze the issue. But this changed this week when the London-based doctorate discovered the secret of Comet McNaught.
Astrophysicist scientist Karl Betham called the Naval Research Laboratory "one of the most beautiful comets we've seen for decades." However, in all its beauty, Comet McNaught had strange patterns in the dusty asthenas described in the video above.
Typically, comet tails, called striae, can extend up to 100 million miles behind the comet's "core", clay, or rocks that form a stable core. The comets actually have two tails: one of them consists of ions (charged atoms), which are manipulated by solar wind magnetic fields, and a dust tail consisting of small pieces of the body taken from a comet nucleus. The McNaught comet dust tail is famous among astronomers because they have a strange "break" structure – otherwise they would be clean lines that are actually contaminated with small trenches, similar to what you can see in the sand dune desert.
These disorders are puzzling Oliver Cena, Ph.D. A student at the University of London College of Mullard Space Science, when he first noticed it, because thanks to it, these dust particles should be too heavy for the sunshine to get into quirky formations. However, they are discontinued. Pricing has substantially complemented this idea:
"This result (and others) has shown that in fact, the sun's wind can also play an important role in dust-borne morphology," he says. Inverted "So, it was really exciting to prove something I learned in the classroom (somewhat) wrong!"
The price was called "strange events" when he first spotted the images depicted in NASA's STEREO and SOHO spacecraft. He was able to combine these images, among other things, to create a three-dimensional map that simulates how each particle of dust moves from the formation of a comet kernel to the tail.
Perhaps most importantly, this simulation illuminated the source of these weird ripples. As the comets speed through the space, the effort falls from the comet's head to tail. As it happens, the comet moves to a magnetic action sheet, and from it, called the heliospheric current. At this point, the magnetic orientation of the solar wind actually changes direction, affecting the way dust particles fall into the comet's tail. You can see that it takes about 1:23 in the video, when dust particles penetrate the page and become slightly moved, causing interruptions on other straight lines.
"It shows that solar-induced magnetic interactions can have a significant effect on the behavior of large dust clouds," he says. He, he adds, can help us discover which forces could make the satellites, planets and comets we see today. This force was at work millions of years ago when the universe really was a huge dust cloud.
"When the solar system was formed, it was essentially one big cloud of dust, which means that we have something else to think about when we think about how the solar system is formed," he concludes.
