Monday was a big day for astronomers around the world as it offered a rare opportunity to observe Mercury crossing the Sun. If you missed all the hype in the run-up to the event, the bad news is that you missed the chance to follow it live. However, the good news is that NASA's Solar Dynamics Observatory (SDO) has looked closely several times and NASA has just released a new video showing transit in magnificent 4K.
The video is just over a minute long, showing the tiny planet passing through our imaging tool in front of our star. The NASA hardware can capture sunlight in a variety of wavelengths, and passing through the various filters of the SDO is a real treat.
NASA's Solar Dynamics Observatory watched as Mercury moved across the sun. The Solar Dynamics Observatory observes the sun in a variety of wavelengths of light in the extreme ultraviolet.
Mercury completes an orbit of the Sun in just 88 days. That's less than a quarter of the time that Earth needs to travel the same journey. Along with the fact that Mercury is not always in line with Earth and Sun as it drives past, it is somewhat rare to see a transit from Earth. Observable transits happen about 13 times per century, but the next time is the end of 2032.
With this video, you really have to hand it over to NASA. It is not only beautiful, but also available in resolutions up to 4K. So, if you've got the chance to put it on a 4K TV, it's definitely worth it. NASA planned to get at least five years of work out of the satellite before it's finished, but we're approaching the tenth year in space ,
