Our sun observing spacecraft, the Solar Dynamics Observatory, witnessed a partial solar eclipse in space on May 25, 2017 when it caught the moon passing in front of the sun. The lunar transit lasted about an hour, between 2:24 and 3:17 p.m. EDT, with the moon covering about 89 percent of the sun at the peak of its journey across the face of the sun.

Great ball of fire! 🔥 This close-up view of the Sun is from a two-hour period on August 13, 2018, showing a minor eruption of charged particles rising up and twisting about before falling back into the Sun. Captured in extreme ultraviolet light, these kinds of events are difficult to see except when they occur along the sun's edge. At its peak, the plasma rises to heights that are several times the diameter of Earth.

The timing of the months in the Islamic calendar is based on astronomical observation. A new month can only begin after a Waxing Crescent Moon is observed shortly after sunset. The Waxing Crescent Moon is the Moon phase which starts right after a New Moon.
Unlike other calendar systems that use leap days or leap months to synchronize the calendar with the solar year, the Islamic calendar is completely detached from astronomical seasons marked by the equinoxes and solstices. An Islamic year consistently falls about 11 days short of the solar year. - from timeanddate.com “it is he who made the sun a shining light and the moon a derived light and determined for it phases - that you may know the number of years and account [of time]. allah has not created this except in truth. he details the signs for a people who know”

Happy 9th anniversary, SDO!

Nine years ago this week, NASA’s Solar Dynamics Observatory or SDO rose into the sky atop an Atlas V rocket. Since that day, SDO has returned over 350 million images of the Sun, produced more than 3,000 scientific articles and allowed millions to see our star in a new light. Here are nine of our favorite SDO images.

1. A coronal mass ejection or CME — a giant eruption of solar material that the Sun often sends out — blew out from just around the edge of the Sun on May 1, 2013.

2. This iconic SDO image shows a long filament of solar material bursting out from the Sun on Aug. 31, 2012.

3. A good portion of the world was watching as Venus glided in front of the Sun for over six hours on June 5 - 6, 2012. SDO implemented specially planned operations to view the event in great detail. The results were the best HD views of a transit ever taken.

4. A pair of solar active regions can be seen on the limb of the sun, offering a beautiful profile of cascading loops — a line of solar particles trapped by the Sun’s magnetic field — spiraling above it on Jan. 15-16, 2012.

5. A giant eruptive event, including a major X-class flare, a coronal wave and a coronal mass ejection, or CME, erupted on Aug. 9, 2011.

6. This image is a composite of 23 separate images spanning the period of January 11, 2015, to January 21, 2016. It illustrates how the Sun’s active regions congregate around the star’s equator. 
7. The Sun emitted three mid-level solar flares — giant bursts of light and radiation from the Sun — on July 22-23, 2016. The x-shape of light seen in this pic is characteristic of a solar flare.

8. Periodically, SDO’s view gets blocked, when Earth passes between it and the Sun. This image is from the Fall 2011 eclipse season. The fuzzy line around Earth shows how our planet’s atmosphere scatters the Sun’s light. 
9. In this SDO image the dark regions show the site of evacuated material from a solar eruption and a flare. The large magnetic loops were formed during the flare in May 2010.

It's Solar Minimum, which means our Sun is at the quietest point of its 11-year activity cycle. That means fewer coronal mass ejections and flares - but more coronal holes. This beauty has been hanging out since August! When it's pointed towards Earth, it can trigger aurora activity, since the Sun's magnetic field is more open over a coronal hole, letting stronger Solar winds escape 🌞 📷: SDO/AIA/@SpaceWxMike/Twitter It's solar minimum, which means our sun is at the quietest point of its 11-year activity cycle. that means fewer coronal mass ejections and flares - but more coronal holes. this beauty has been hanging out since august! when it's pointed towards earth, it can trigger aurora activity, since the sun's magnetic field is more open over a coronal hole, letting stronger solar winds escape 🌞 📷: sdo/aia/@spacewxmike/twitter

The #SolarDynamicsObservatory, our Sun-watching #satellite, saw the Moon seem to pause ⏸ and rewind ⏪ as it passed in front of the Sun on March 6. The Moon didn't actually change directions — the apparent reversal is a result of the relative speeds of the Moon and the #spacecraft .
#SDO sees lunar transits regularly, when the Moon passes in front of its view of the Sun. The Moon's unusual apparent behavior during this particular transit is a phenomenon similar to retrograde motion, when a celestial object appears to move backward because of the way different objects move at different speeds at different points in their orbits.
This lunar transit lasted about four hours, from 5 p.m. to 9:07 p.m. EST, and, at peak, the Moon covered 82 percent of the Sun's face.

Double Solar Eclipse but only for one lucky guy, the SDO (Solar Dynamics Observatory)
.
.
On the evening of March 6, 2019, the Moon started to transit the Sun, then doubled back and retraced its steps in the other direction—at least, that's what it looked like from the perspective of NASA's Solar Dynamics Observatory, or SDO, in orbit around Earth.

SDO sees lunar transits regularly, when the Moon passes in front of its view of the Sun. The Moon's unusual apparent behavior during this particular transit is a phenomenon similar to retrograde motion: When a celestial object appears to move backwards because of the way that different objects move at different speeds at different points in their orbits.

sdo sees lunar transits regularly, when the moon passes in front of its view of the sun. the moon's unusual apparent behavior during this particular transit is a phenomenon similar to retrograde motion: when a celestial object appears to move backwards because of the way that different objects move at different speeds at different points in their orbits. in this case, the first part of the transit—when the moon moves left to right—appears to be "reverse" motion. sdo overtakes the moon, moving at about 1.9 miles per second perpendicular to the sun-earth line compared to the moon's 0.6 miles per second, making the moon appear to move in the opposite direction you would see if you were standing still on earth.

the second part of the transit—when the moon appears to pause and rewind—happens as sdo enters the dusk part of its orbit and begins moving away from the moon, nearly parallel to the shadow it's casting through space. at that point, the moon once again moves faster than sdo—when compared to the sun-earth line—overtaking it. so the spacecraft now sees it move in the other direction—the same direction that a stationary observer on earth would see.

NASA Image of the Day is amazing!! NASA's Solar Dynamics Observatory (SDO) scientists used their computer models to generate a view of the Sun's magnetic field on August 10, 2018. The bright active region right at the central area of the Sun clearly shows a concentration of field lines, as well as the small active region at the Sun's right edge, but to a lesser extent. Magnetism drives the dynamic activity near the Sun's surface.

SDO is managed by NASA's Goddard Space Flight Center, Greenbelt, Maryland, for NASA's Science Mission Directorate, Washington. Its Atmosphere Imaging Assembly was built by the Lockheed Martin Solar Astrophysics Laboratory (LMSAL), Palo Alto, California.

Our Sun. It's a dynamic place. Here, is a computer model that generates a view of the Sun's magnetic field, allowing scientists to better monitor active regions and understand how solar material courses around the Sun's surface. Using real-time data taken from our Solar Dynamics Observatory on August 10, 2018, we see a bright active region right at the central area of the Sun. It clearly shows a concentration of field lines, as well as the small active region at the Sun's right edge, but to a lesser extent. Magnetism drives the dynamic activity near the Sun's surface.

The observatory helps us understand the Sun's influence on Earth and near-Earth space by studying the solar atmosphere on small scales of space and time and in many wavelengths simultaneously.

Размер этого Солнечный танец

Солнечные протуберанцы — это плазменные образования, которые поднимаются над светилом и удерживаются его магнитным полем. Они постоянно движутся и могут вздыматься на десятки тысяч километров.

Размер этого "танцующего" протуберанца огромен – вся Земля, диаметр которой 12742 километра, легко поместится под аркой из текущего горячего газа.

В спокойном состоянии протуберанец может существовать около месяца, однако он может взорваться, породив корональный выброс – поток горячего газа, выбрасываемого в Солнечную систему.

Видео охватывает 3 часа реального времени и показывает поверхность нашей звезды в ультрафиолетовом диапазоне.
