NASA’s Juno Spacecraft data suggests “Sprites” or “Elves” dance in Jupiter’s Atmosphere

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – New results from NASA’s Juno mission at Jupiter indicates that either “sprites” or “elves” could be dancing in the upper atmosphere of the solar system’s largest planet.

It is the first time these bright, unpredictable and extremely brief flashes of light – formally known as transient luminous events, or TLE’s – have been observed on another world. The findings were published on October 27th, 2020, in the Journal of Geophysical Research: Planets.

Schools Will Reopen, Viruses Will Persist, Can We Protect Our Community?

 

RobotLABSan Francisco, CARobotLAB Inc., the leading Educational Robotics Company, announced today the launch of a suite of Virus-Fighting robots to keep schools safe and virus-free. The suite of robots, carefully chosen from all around the world, are designed to follow the UNICEF’s guidelines for safe and virus-free schools.

With Dr. Fauci’s expectation that the Coronavirus (COVID-19) will become a cyclical disease, it is more important than ever to ensure that schools, and our kids are safe, and not spreading infections throughout the community.

NASA’s Search for Life

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA says in the hunt for life on other worlds, astronomers scour over planets that are light-years away. They need ways to identify life from afar — but what counts as good evidence?

Our own planet provides some inspiration. Microbes fill the air with methane; photosynthesizing plants expel oxygen. Perhaps these gases might be found wherever life has taken hold.

NASA Model gives new information on Spiraling Supermassive Black Holes

 

Written by Jeanette Kazmierczak
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions to billions of times the mass of the Sun, spiral toward a collision. For the first time, a new computer simulation that fully incorporates the physical effects of Einstein’s general theory of relativity shows that gas in such systems will glow predominantly in ultraviolet and X-ray light. 

Just about every galaxy the size of our own Milky Way or larger contains a monster black hole at its center. Observations show galaxy mergers occur frequently in the universe, but so far no one has seen a merger of these giant black holes.

How Can I Protect My Children from the Sun?

 

Centers for Disease Control and PreventionAtlanta, GA – Just a few serious sunburns can increase your child’s risk of skin cancer later in life. Kids don’t have to be at the pool, beach, or on vacation to get too much sun. Their skin needs protection from the sun’s harmful ultraviolet (UV) rays whenever they’re outdoors.

Seek shade. UV rays are strongest and most harmful during midday, so it’s best to plan indoor activities then. If this is not possible, seek shade under a tree, an umbrella, or a pop-up tent. Use these options to prevent sunburn, not to seek relief after it’s happened. «Read the rest of this article»
