Airglow is the constant, faint glow of Earth’s upper atmosphere created by the interaction between sunlight and particles in this region. The phenomenon is similar to auroras, but where auroras are driven by high-energy particles originating from the solar wind, airglow is energized by ordinary, day-to-day solar radiation.

Studying airglow gives scientists clues about the upper atmosphere’s temperature, density, and composition, and helps us trace how particles move through the region itself. Two NASA missions take advantage of our planet’s natural glow to study the upper atmosphere: ICON focuses on how charged and neutral gases in the upper atmosphere interact, while GOLD observes what’s driving change — the Sun, Earth’s magnetic field or the lower atmosphere — in the region.

By watching and imaging airglow, the two missions enable scientists to tease out how Earth’s weather and space intersect, dictating the region’s complex behavior. https://go.nasa.gov/2RJax4x

The scientists believe the twist at the center of the image marks the spot where the baby planet could be forming.

A couple years ago, scientists managed to take images of spiral arms of gas surrounding a star that scientists believe were early evidence of planet formation — but the “twist” at the center adds something new to the story.

“The twist is expected from some theoretical models of planet formation, ” Anne Dutrey, another co-author from the LAB, said in the statement. ” It corresponds to the connection of two spirals — one winding inwards of the planet’s orbit, the other expanding outwards — which join at the planet location.”

Every once in a while I have a contentious discussion with someone about traveling to Mars, and the risks involved. One of the hardest risks to describe is the threat from galactic cosmic rays. Here is a short article about a new facility investigating the effects of galactic cosmic rays.

The very important point here is that we are not discussing electromagnetic radiation. These ions have been shown to sometimes penetrate spacecraft and inflict damage on astronauts brains. Earthlings do not have to worry about these as much because we have a magnetosphere that shields us from ions.

To better understand and mitigate the health risks faced by astronauts from exposure to space radiation, we ideally need to be able to test the effects of Galactic Cosmic Rays (GCRs) here on Earth under laboratory conditions. An article publishing on May 19, 2020 in the open access journal PLOS Biology from Lisa Simonsen and colleagues at the NASA Langley Research Center, USA, describes how NASA has developed a ground-based GCR Simulator at the NASA Space Radiation Laboratory (NSRL), located at Brookhaven National Laboratory.

Galactic cosmic rays comprise a mixture of highly energetic protons, , and higher charge and energy ions ranging from lithium to iron, and they are extremely difficult to shield against. These ions interact with spacecraft materials and to create a complex mixed field of primary and secondary particles.

The reality of COVID19 raises a critical question in the mind of Adam Ethan Loeb a young Belgium boy regarding the extinction of the human person. This questions birthed “Adam’s Dream” which for him will help in “Saving Humanity From Extinction”, by “Availing a Multiplanetary Education for the present and Future Generations“
This 12year old boy highly influenced by Elon Musk and Peter H. Diamandis believes that a multiplanetary existence could have prevented the spread of coronavirus.
This young Space Enthusiast believes that since they are the future of tomorrow, well structure Young Space Education System should be availed because the Future is Faster than we think.

In explaining his vision Adam explained, “Adam’s Dream is my vision about the future with regard to preserving our kind and other living things. This idea struck my mind during this novel coronavirus outbreak. As the spread increases day in and day out, I was scared and asked my mum the question, “mum, do you know that living in space could have saved or preserved humanity better”? My reason is, if we become multiplanetary, it will solve the problem of overpopulation and make the human person more creative and resilient.

Thus, in this project, I will be preparing my generation and the ones to come to become multiplanetary Species. We have many Space Advocates; there is no proper attention giving to the younger generation. The future is obscure for my generation, and I want to lead them to light through the help of those who know better in compliance with “Adam’s Dream” rooted in Saving Humanity from Extinction by Availing a Multiplanetary Education for the present and Future Generations. In this, we can have a Sustainable “Kosmic” Environment for Prosperous Living.

You might like this interview I did with futurist writer Nikola Danaylov, who runs the Singularity Weblog and wrote ‘Conversations with the Future: 21 Visions for the 21st century’, on how advances in AI could utterly transform human society and the health of the global transhumanist movement.

I’m trying to grow my futurism YouTube channel (transhumanism, AI, space colonisation etr) so if this is of interest to you I’d be very grateful for any subscribers.
