    NASA Finds Giant Hole on Sun's Surface
    NASA's Solar Dynamics Observatory snapped this picture of the Sun on Jan. 1, 2015.

    Okay, it's not a literal hole.

    And the sky isn't falling either.


    On Jan. 1, NASA noticed that its Solar Dynamics Observatory satellite had snapped a surprising image of the sun.

    In the picture above, what looks like a massive chunk of Sun missing is actually a coronal hole.

    As NASA explains in a blog post, coronal holes are areas of the sun's corona, its distinctive aura, where the star's magnetic field shoots out into space rather than loop back to the surface.

    The sun's psychedelic glow in NASA's high-res photos is caused by energy and gas trapped on the surface by the sun's magnetic field. In coronal holes, where the field extends into space, those particles leave the sun, and that region goes black.

    This crisp image of the phenomenon isn't the first, however.

    In the early 1970s, scientists onboard the Skylab space station took the first images of coronal holes.

    Last summer, NASA captured an image of a massive coronal hole spanning at least 400,000 miles across, which it explained was "more than 50 Earths side by side."

    Here is my question... Will this go back to the normal way the Sun is supposed to be as?

    Well maybe time to use the greenhouse to counter greenhouse effects? This way you can use shade clothe on high ray days and take it off when sun is not so close? :sun::cool:

    How can that be? - There's no humans on Mars to jack up the temperatures...

    Scientists find evidence of global warming on Mars
    Tuesday, May 31, 2016 - Earth isn’t the only planet grappling with climate change, although this other orb doesn’t have much in the way of fossil fuel emissions or a 97 percent of scientific “consensus” on global warming. Newly published evidence suggests Mars is experiencing global warming as it emerges from an ice age.

    Scientists: Plant More Trees to Combat Climate Change
    October 16, 2017 — Planting forests and other activities that harness the power of nature could play a major role in limiting global warming under the 2015 Paris agreement, an international study showed Monday.
