Voyager 2, Voyager program, Earth, NASA lar Probes Find Amazing Things On The Sun
It has been studied with great interest for thousands of years, and yet we know very little about it, but humanity is on a mission to touch the sun and advanced telescopes are being built on earth and some sent into space to help us solve the sun’s greatest Mysteries mankind’s greatest inventions are now sending back incredible images of our star as you’ve. Never seen it before Music sitting at the center of our solar system is a nearly perfect sphere of burning. Sizzling plasma, radiating, intense heat and light earth resides in the vast atmosphere of the sun, which creates a complex space environment that sometimes interferes with space technology, communications, navigation systems and utility grids. If we can predict severe space weather from the sun in future, it could help us prepare for solar storms, but we need to get closer to understand it. Now new telescopes on earth are taking images of the sun in mind, melting detail. The daniel k, inouya solar telescope, sits on top of a mountain on the island of maui in hawaii and is the world’s largest sun spotting telescope on january 30th, 2020. The telescope snapped some high resolution images of the sun, showing a pattern of turbulent boiling plasma covering the surface. The hot solar plasma rising in the bright centres of the cell cools off and sinks below the surface in dark lanes. A process called convection, but the inoye solar telescope was just getting warmed up an image taken on december 11.
2020 is the most detailed photo of a sunspot that humans have ever seen, showing magnetic structures as long as 12 miles, the sunspot appears as a fiery heart that is 10 000 miles across that’s big enough for the earth to fit inside. The dark region is a concentration of magnetic fields that block heat within the sun from reaching its surface, even though this dark area of the sunspot is cooler than the brighter parts, it’s still more than seven and a half thousand degrees fahrenheit, it was discovered that stretching Out from those dark regions, thought to be empty are strands of hot electrified gases that stretch out for miles. The amazing images showed that each strand is 1.8 million degrees fahrenheit. The most incredible thing is that the inoye solar telescope captured this image of the sunspot before the facility was completed, meaning the telescope will be capable of producing even more amazing images using its advanced optics and 13 foot primary mirror. Currently, these are the best images taking of the sun from earth, but now there are telescopes out in space that can take even better images. Nasa’S solar dynamics observatory was launched into geosynchronous orbit above the earth. On february, the 11th 2010. it’s a cargo van sized piece of equipment that has three main instruments: the atmospheric imaging assembly, which is a battery of four telescopes that are designed to photograph the sun’s surface and atmosphere, the extreme ultraviolet variability experiment, evee that measures the sun’s Ultraviolet output and the helioseismic and magnetic imager, which can map solar magnetic fields and look below the sun’s opaque surface using a technique called helioseismology studying the sun by listening to it and observing vibrations on its surface, it’s been recording the sun for over 10 years and In time lapse footage you can see an extreme ultraviolet wavelength showing the sun’s outer corona and the rise and fall of the solar cycle.
The sun goes through a solar cycle every 11 years, where it expands and retracts in size when this happens, the sun’s, north and south poles trade places. This cycle has been observed for centuries by changes in the appearance of the sun itself, as well as phenomena like the northern lights here on earth. Over the course of this 11 year cycle activity on the sun can be observed in a state of synchronized fluctuation, solar, flares, coronal, mass ejection, sunspots coronal loops and even the level of solar radiation are all tied to these 11 year cycles from planet earth. The sun looks like a rather stable celestial body, but, as we get closer we can see. The sun is very volatile. Solar flares occasionally shoot out of the surface blasting a large cloud of energetic and highly magnetized plasma into space called coronal mass ejections on july 19. 2012, the ultra high definition telescope aboard nasa’s solar dynamics, observatory captured hours of stunning footage of a solar flare erupting from the sun, the gigantic ark much bigger than the planet earth. The compressed footage shows the million degree plasma begin to cool and fall to the surface. An electrifying magnetic downpour of coronal rain, the charged plasma is strongly influenced by the sun’s magnetic field as the plasma rain down it condensed along twisted magnetic field lines close to the surface, forming giant streaming, arcs, some as tall as five earths. On april, the 17th 2016. The solar orbiter captured stunning images of a mid level, solar flare erupting from the surface of the sun.
The amazing footage may help us understand what causes these powerful bursts of radiation. Powerful flares happen all the time, but solar flares aren’t always strong enough to create mass coronal ejections of plasma most of the time they show up as bright spots on the surface. But when plasma is kicked out of the sun, it can be a breathtaking phenomenon. The largest flares could have the potential to cause worldwide blackouts across the earth if a solar flare, big enough, were to hit us and the earth has almost been hit recently by a solar flare in november 2020, a very large solar flare erupted from the sun and Narrowly missed the earth, but there’s no need to panic as this sort of activity isn’t happening all the time, and when it does happen, the flare would have to be timed just right, even though we have the powerful telescope in orbit. We have other spacecraft headed toward the sun right now, a joint project by nasa and the european space agency. The 550 million dollar solar orbiter was launched february 2020 and is one of the most complex scientific spacecraft to be sent towards the sun. The solar orbiter was sent on a mission to take the first ever pictures of the north and south poles of the sun. The probe carries 10 different instruments on board, including high resolution telescopes and other measuring devices. Its objective is to get as close as 26 million miles from the sun and study the massive fireball at a tilt in orbit, allowing it to view the poles directly places.
No human has ever seen before. Solar orbiter has to withstand incredible temperatures from minus 300 degrees. Fahrenheit in the cold of space to over 900 degrees fahrenheit as it approaches the sun because of this, the instruments on board are protected by a titanium heat shield that has a calcium, phosphate coating. But the environment is so harsh that it does not have a camera facing the sun. Despite this, the solar orbiter has taken some incredible photographs and footage on its way to the sun. On november, the 18th 2020, the heliospheric imager camera on board the spacecraft, grabbed images of venus earth and mars. New images of the sun taken just 48 million miles from its surface are the closest images ever captured by cameras and they revealed something never seen before. Mini flares all over the sun, a millionth, the size of a regular solar flare, called campfires it’s, not clear. Yet what these mini flares are, but they could be mini. Explosions called nano flares which may help heat the sun’s atmosphere. You probably didn’t know that the surface of the sun has a relatively cool surface temperature of 9941 degrees, fahrenheit, but it’s, surrounded by a super hot atmosphere of more than a million degrees and that’s. Not all it was about 80 years ago, when scientists found the temperature of the solar corona is much hotter than the surface of the sun by 5 million degrees. Fahrenheit. The high temperatures of the corona caused it to expand into space as a continuous outflow of plasma called the solar wind.
It extends past the planets forming a bubble, called the heliosphere wrapping around everything in the solar system, but how the sun accelerates this solar, wind and propagates it out to the solar system is a giant mystery to investigate this and other strange solar phenomenon. The 1.5 billion parker solar probe was launched in 2018 to study the outer corona of the sun. It will fly very close to the sun coming within four million miles of the fiery plasma ball that’s seven times closer than any spacecraft has come before. You may be wondering if the probe gets so close to the sun won’t, it burn up. The parker solar probe is designed to swoop through the sun’s super hot outer atmosphere, but in order to survive the high temperature and complete its seven year mission, it needs to be traveling very fast, so it will swing by venus a total of seven times. One of the first images parker solar probe, took during its close encounter with the sun, shows a streamer of plasma in the outer solar corona. The bright spot below the photo is the planet. Mercury by the end of its mission in late 2025, at its closest approach, parker solar probe will be hurtling around the sun at 430 000 miles per hour. The front of parker, solar probe shield will face radiation and heat as high as 2500 degrees fahrenheit, but the instruments on the other side will be near room temperature. What do you think the parker solar probe will discover, and what do you think the poles of the sun will look like when the solar orbiter completes its mission by studying the star that we live with? We’Ll learn more about other stars in the universe and we may be able to predict when solar storms will erupt with everything that we’ve learned.
We still don’t know what’s inside the sun, but that could change very soon. If you enjoyed the video, then stay tuned.
