Observe the inverted moon as it traverses the sun in a mind-boggling animation – as revealed by NASA, NO sun signs have been observed throughout the past month.
- NASA shared a superb animation from observations of its SDO captured on March 6
- Due to the movement of the satellite and the moon, the moon seems to go back
- At the same time, a space agency revealed that the sun was exceptionally calm
NASA shared a new disconcerting animation showing "a turning point" in the typical lunar transit.
Thanks to the movement of its Solar Dynamics observatory combined with that of the moon in orbit, the lunar shadow seems to reverse its direction when the moon moves in front of the sun.
The incredible phenomenon appeared in the sightings captured by SDO on March 6th.
The sun is currently experiencing a period of unusual calm as the solar minimum approaches; According to NASA, there were no visible sunspots in February.

NASA shared a new confusing animation showing "a twist" in the typical lunar transit in which the lunar shadow seems to reverse its direction when the moon moves in front of the sun
This is a weird effect that could leave many viewers scratching their heads.
But according to NASA, the phenomenon is simply a result of the evolution of SDO's perspective.
"The apparent reversal of the moon is due to the fact that SDO first overtook the Moon in its orbit, and then the moon caught up when the SDO swung around the twilight of the Earth," NASA said. .
"During transit, the sun moves in the frame as the telescopes cool down and flex in the lunar shadow."
NASA's SDO has been monitoring activity in the sun for almost a decade.
The sun has been relatively quiet in recent months, as it approaches a phase of its so-called solar minimum cycle.
According to NASA, there were no sunspots at all in February – a phenomenon that has not been observed since 2008.
But this is not a matter of concern, insists the space agency.
"Where are all the sunspots? Last month, the total number of points that crossed our Sun was … zero, "NASA revealed on its Astronomy Picture of the Day blog.
"Well below the long-term monthly average, the Sun's surface has become as unusually unusual as this solar minimum, just like it was 11 years ago, at the last solar minimum.
According to NASA, the phenomenon of the inverted moon is simply the result of the changing perspective of SDO. This is illustrated in the animation above
"Such passivity is not simply a visual spectacle, it is related to the fact that the Sun is slightly weaker, to the holes in the Sun's crown more stable and to a reduced intensity in the outgoing solar wind.
"The reduced wind, in turn, cools and collapses the Earth's outer atmosphere (the thermosphere), resulting in reduced drag on many Earth-orbiting satellites."
NASA has long estimated that the sun would reach its minimum in 2019-2020, and the last activity – or lack of activity – fits those forecasts.
The sun is currently going through an unusual period of "calm" as the solar minimum approaches; According to NASA, there were no visible sunspots in February. Above, the sun can be seen last August, already appearing almost without spots
The space agency is working to better understand the mechanisms of solar activity with the recently launched Parker solar probe, whose second solar orbit was launched in January.
It will get closer to the sun on April 4th.
"We always said that we did not know what to expect before we examined the data," said Nour Raouafi, project scientist, APL. Said in January.
"The data we have received alludes to a lot of new things we have never seen before and to new potential discoveries. Parker Solar Probe keeps its promise to reveal the mysteries of our sun. "
