Ever wondered? Why is Russia experiencing chill winters, whereas Dubai is witnessing hot summers at the very SAME time! What makes the season change? The answer is in the movement of the earth in space. By that, we don’t mean Earth literally walking or rolling all across space, but yes! It rolls on a very specific path, its orbit! Since ancient times, by looking at the sky, humans have been able to orient themselves and calculate the passage of time through repeating cycles. And that’s what has been bringing changes to the seasons! Stay till the end of the video to discover more about it!

Have you ever wondered how the Earth rotates? Everyday, we wake up, go to work, interact with our friends and families, and generally just go about our lives without noticing that our planet is constantly rotating. Well, in this video, we are taking a trip to space to better understand Earth’s rotation! So strap on your space suit and start the countdown as we head to the stars to find out how and why our planet rotates!

Go outside with NASA and watch the total lunar eclipse! On the evening of May 15, Earth will pass between the Sun and the Moon, blocking sunlight and casting a shadow on the lunar surface. Starting at 9:32 p.m. EDT (1:32 UTC on May 16), people with clear skies in the Americas, Europe, and parts of Africa will begin to see the Moon get bathed in the red glow of every sunrise and sunset refracted through Earth’s atmosphere. Totality will occur at 12:12 a.m. EDT on May 16 (4:12 UTC).

NASA’s Solar Dynamics Observatory — SDO — has now been watching the Sun non-stop for over a full decade. From its orbit in space around the Earth, SDO has gathered 425 million high-resolution images of the Sun, amassing 20 million gigabytes of data over the past 10 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system. With a triad of instruments, SDO captures an image of the Sun every 0.75 seconds. The Atmospheric Imaging Assembly (AIA) instrument alone captures images every 12 seconds at 10 different wavelengths of light. This 10-year time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength that shows the Sun’s outermost atmospheric layer — the corona. Compiling one photo every hour, the movie condenses a decade of the Sun into 61 minutes. The video shows the rise and fall in activity that occurs as part of the Sun’s 11-year solar cycle and notable events, like transiting planets and eruptions. The custom music, titled “Solar Observer,” was composed by musician Lars Leonhard (https://www.lars-leonhard.de). While SDO has kept an unblinking eye pointed towards the Sun, there have been a few moments it missed. The dark frames in the video are caused by Earth or the Moon eclipsing SDO as they pass between the spacecraft and the Sun. A longer blackout in 2016 was caused by a temporary issue with the AIA instrument that was successfully resolved after a week. The images where the Sun is off-center were observed when SDO was calibrating its instruments. SDO and other NASA missions will continue to watch our Sun in the years to come, providing further insights about our place in space and information to keep our astronauts and assets safe.
