Solstice And Appearance Of Sun In Different Wavelengths

This video, made by Scientific Visualization Studio at NASA's Goddard Space Flight Centre, Greenbelt exemplifies the appearance of the sun when viewed in different wavelengths.

This video, made by Scientific Visualization Studio at NASA’s Goddard Space Flight Centre, Greenbelt exemplifies the appearance of the sun when viewed in different wavelengths.

These wavelengths, apparently can only be perceived by the telescope. So NASA’s Solar Dynamics Observatory (SDO) converts these wavelengths into an image human eyes can perceive, followed by colorization of light into a rainbow of colors.

Furthermore today (December 21st), the winter solstice will approximately happen at 1711 hours UT in the Northern Hemisphere; it is the time when the Sun reaches the southernmost declination in its yearly journey. At the same time – the summer solstice will happen in the Southern Hemisphere.

Today, you will be experiencing the shortest day and longest night of the year.

  1. Thanks so much. Very cool, I mean very phreakin’ HOT actually πŸ˜‰

    But seriously, I disagree that there is a rational explanation for EVERYTHING. Or rather, there is, but human’s are not omniscient, so we cannot know all the answers. (I’m a hard core physicists btw.) And this is what makes science so wonderful. No end of questions, no end of sources of inspiration. πŸ™‚

    1. I actually believe there is a rational explanation for everything and I am hopeful an era will come when humans will know almost everything if not everything (look at the researches being carried out everyday and for now, it’s only happening in developed countries, just imagine if whole world is busy discovering and inventing. Anyway, thanks for liking and Good luck with your Physics.:D

    1. Yes, there is a lot going on which our senses cannot perceive directly, but it’s our senses that built us microscopes, computers and there’s telescope to observe for us. So, thanks to our senses we can observe and interpret anything directly with telescopes. πŸ™‚

      1. Well, perhaps it’s our knowledge derived from our senses that helps expand the boundaries of our senses through optics, telescopes etc.

    1. Yes, Science is the future of humanity. As science progresses, people will become aware that there’s a rational explanation for everything that is and happens. Let’s hope more and more people are inclined to study Science and invent, we could be living on some other planet by the end of 21st century. πŸ˜€

      1. I agree… I have one Scientist and two Engineers in my family πŸ™‚ Thank you for introducing us the advanced technology! Merry Christmas and Happy Holidays to you, Sparkonit!
