The video covers 12:30 a.m. EDT to 10:00 p.m. EDT on July 19, 2012.In reality, the sun is not made of fire, but of something called plasma: particles so hot that their electrons have boiled off, creating a charged gas that is interwoven with magnetic fields. In this wavelength it is easy to see the sun's 25-day rotation as well as how solar activity has increased over three years.During the course of the video, the sun subtly increases and decreases in apparent size. Telescopes can also collect light in ranges that our eyes alone cannot see, providing scientists ways of observing a whole host of material and processes that would otherwise be inaccessible. Transits provide a great opportunity to study the way planets and stars move in space– information that has been used throughout the ages to better understand the solar system and which still helps scientists today calibrate their instruments. As of June 2020, NASA’s Solar Dynamics Observatory – SDO – has now been watching the Sun non-stop for over a full decade. To see how this event may affect Earth, please visit NOAA's Space Weather Prediction Center at http://spaceweather.gov, the U.S. government's official source for space weather forecasts, alerts, watches and warnings. They are categorized as mid-strength flares, substantially less intense than the most powerful solar flares.Around 13 times per century, Mercury passes between Earth and the sun in a rare astronomical event known as a planetary transit. 304 and 171 show the atmosphere of the Sun, which does not appear in the visible part of the spectrum. It has examined the Sun's atmosphere, magnetic field and also provided a better understanding of the role the Sun plays in Earth's atmospheric chemistry and climate. NASA's SDO views the sun in 13 different wavelengths, each chosen to emphasize a specific aspect of the sun's surface or atmosphere. Watch the movie to see giant clouds of solar material hurled out into space, the dance of giant loops hovering in the corona, and huge sunspots growing and shrinking on the sun's surface.

• February 11, 2015 marks five years in space for NASA's Solar Dynamics Observatory, which provides incredibly detailed images of the whole sun 24 hours a day.
The Solar Dynamics Observatory views the Sun in a variety of wavelengths of light in the extreme ultraviolet.X-class denotes the most intense flares, while the number provides more information about its strength. Magnetic fields are invisible, but the plasma is very obvious in the extreme ultraviolet wavelength of 304 angstroms, which highlights material at a temperature of about 50,000 Kelvin. built, operates, and manages the SDO spacecraft for NASA's Science Mission Directorate in Washington, D.C.Information about the individual clips used in this video is When the science team released its first images in April of 2010, SDO's data exceeded everyone's hopes and expectations, providing stunningly detailed views of the sun. While SDO has kept an unblinking eye pointed towards the Sun, there have been a few moments it missed. 211: This wavelength shows hotter, magnetically active regions in the sun's corona. It also shows the coronal mass ejections — great clouds of solar material bursting off the sun into space — during that time as captured by the ESA/NASA Solar and Heliospheric Observatory.The View from SDO: The August 31, 2012 Filament EruptionFilament Eruption Creates 'Canyon of Fire' on the SunThe View from SDO: The August 31, 2012 Filament EruptionFilament Eruption Creates 'Canyon of Fire' on the SunThe View from SDO: The August 31, 2012 Filament EruptionFilament Eruption Creates 'Canyon of Fire' on the SunThe View from SDO: The August 31, 2012 Filament EruptionFilament Eruption Creates 'Canyon of Fire' on the SunFull-resolution 4k resources for the series of early September flares from active region 2673. --an M7.3 at 6:15 a.m. EDT on Sept. 7, 2017 And then, the sun treated viewers to one of its dazzling magnetic displays — a phenomenon known as coronal rain. Visualizers at NASA's Goddard Space Flight Center in Greenbelt, Md. The mountains and valleys on the horizon of the LRO picture fit right into the shadows seen by SDO. Launched on Feb. 11, 2010, SDO keeps a 24-hour eye on the entire disk of the sun, with a prime view of the graceful dance of solar material coursing through the sun's atmosphere, the corona. Gradients are, in fact, a mathematical description that highlights the places of greatest physical change in space. NASA’s Solar Dynamics Observatory caught this image of an eruption on the side of the sun over June 18, 2015. SDO collected one frame every 12 seconds, and the movie plays at 30 frames per second, so each second in this video corresponds to 6 minutes of real time. This plasma acts as a tracer, helping scientists watch the dance of magnetic fields on the sun, outlining the fields as it slowly falls back to the solar surface.
