NASA discovers man-made bubble around Earth

In the course of just one year a spacecraft observing Earth spotted hundreds of mysterious ‘flashes’ reflecting off the surface of our planet. One such flash can be seen over South America above

NASA decodes source of strange flashes seen on Earth from space

Going by the physics of reflection of light, only certain sports on Earth should produce such reflections, they said.

In 2015, the Deep Space Climate Observatory (DSCVOR) satellite began to detect unexplainable flashes of light all over Earth.

Most of us won't have much to do with VLF signals in our everyday life, but they're a mainstay in many engineering, scientific, and military operations.

So there you have it - mystery solved!

Almost a quarter-century later, DSCOVR found flashes of light over land as well.

The study, which was published in the journal Space Science Reviews under the title "Anthropogenic Space Weather", was conducted by a team of scientists from the USA and Imperial College, London. A closer look at the area further debunked the idea as the respective pieces of land held no lakes or water sources.

However, Marshak's research found that the flashes have a simple explanation. Astronomer Carl Sagan had observed similar reflections from Earth back in 1993, when he was looking at images taken by Galileo spacecraft. So what are these flashes and where are they coming from? They tested their idea by taking an inventory of sun glints hitting land in the satellite images, where the bursts took place 866 times from June 2015 to August past year.

This bubble is even seen by spacecraft high above Earth's surface, such as NASA's Van Allen Probes. Led by Dr. Tamas Gombosi, a professor at the University of MI and the director at the Center for Space Modelling, the team reviewed the impact anthropogenic processes have on Earth's near-space environment. Reflections of sunlight glinting off oceans? "So this possibly may help us see them if their starlight glints off in the same way", he said.

The team followed the same thought process and targeted water as the main culprit.

These particles, along with electromagnetic energy that accompanies them, can also cause auroras, while changes in the magnetic field can induce currents that damage power grids. These clouds are made up of, what else, ice crystals.

Since it seemed like bodies of water were not the source of the flash, Marshak joined forces with Tamas Varnai of the University of Maryland, Baltimore County, and Alexander Kostinski of Michigan Technological University, using date from EPIC to figure it out.

At times, these interactions can create a barrier around Earth against natural high energy particle radiation in space, showed the results of a study published in the journal Space Science Reviews.

To test their theory, the researchers reasoned that if the flashes were caused by sunlight bouncing off ice particles, then the shots would have to be occurring when DSCOVR was in such a position that sunlight would be reflected directly at it when it hit the crystals.
