NASA'S Travel Poster to Earth


There's no place like home. Warm, wet and with an atmosphere that's just right, Earth is the only place we know of with life – and lots of it. JPL's Earth science missions monitor our home planet and how it's changing so it can continue to provide a safe haven as we reach deeper into the cosmos.

EVERY TIME LIGHTNING STRIKES, MATTER-ANTIMATTER ANNIHILATION HAPPENS TOO

For some time, physicists have been aware that small bursts of high-energy gamma rays can be produced by lightning storms – what are known as “terrestrial gamma-ray flashes”. They are believed to be the result of static electrical fields accelerating electrons, which are then slowed by the atmosphere. This phenomenon was first discovered by space-based observatories, and rays of up to 100,000 electron volts (100 MeV) have been observed.

Thanks to the success of their campaign, the team built and installed particle detectors across the northwest coast of Honshu. In February of 2017, they installed four more detectors in Kashiwazaki city, which is a few hundred meters away from the neighboring town of Niigata. Immediately after the detectors were installed, a lightning strike took place in Niigata, and the team was able to study it.

It was here that things really got interesting. As the unstable nitrogen broke down, it released positrons that then collided with electrons, causing matter-antimatter annihilations that released more gamma rays. As Enoto explained, this demonstrated, for the first time that antimatter is something that can occur in nature due to common mechanisms.

The Great AMERICAN Eclipse of August 21, 2017

Image: The Moon’s shadow will dramatically affect insolation — the amount of sunlight reaching the ground — during the total solar eclipse. Credit: NASA’s Scientific Visualization Studio 160 seconds of totality is a fleeting but, so I’m told, haunting experience. For scientists, though, we’d like a good bit more. Thus it’s welcome news that the European Space Agency is working on Proba-3, a duo of small satellites designed to interact with each other to block the solar disk over and over again. The camera satellite and disk satellite engage in precision flying, creating artificial eclipses of six hours each time the two craft make one 19.6 hour orbit.

Near Earth phenomenon

Magnetic fields

Magnetic TURBULANCE near the earth



NASA's Magnetospheric Multiscale (MMS) spacecraft has detected magnetic activity occurring in a new and surprising way in the environment of near-Earth space. Earth is surrounded by charged particles known as plasma. Most of these high-energy particles are deflected by the magnetosphere, which is the protective magnetic field that surrounds the planet. As Earth's magnetic-field lines absorb this energy, they stretch and eventually snap, releasing powerful bursts of particles toward Earth, which, in turn, can endanger satellites, spacecraft and astronauts in space. This process, known as magnetic reconnection, is commonly observed in Earth's magnetosphere, generally under calm conditions. However, new data from NASA's MMS has shown for the first time that this process also occurs in the extremely turbulent near-Earth environment known as the magnetosheath, according to a statement from NASA.

NASA | Van Allen Probes Reveal Previously Undetected Radiation Belt Around Earth

It?s a well-known fact that Earth?s ozone layer protects us from a great deal of the Sun?s ultra-violet radiation.
Were it not for this protective barrier around our planet, chances are our surface would be similar to the rugged and lifeless landscape
we observe on Mars.
Beyond this barrier lies another ? a series of shields formed by a layer of energetic charged particles that are held in place by the
Earth?s magnetic field. Known as the Van Allen radiation belts, this wall prevents the fastest, most energetic electrons from reaching Earth.

Published on Feb 28, 2013 These two nearly identical spacecraft launched in August 2012 and with only six months in operation, they may well be rewriting science textbooks.
The probes study the Van Allen belts, gigantic radiation belts surrounding Earth, which can swell dramatically in response to incoming energy from the sun,
engulfing satellites and spacecraft and creating potential threats to manned space flight.
James Van Allen discovered the radiation belts during the 1958 launch of the first successful U.S. satellite. Subsequent missions have observed parts of the belts, but what causes the dynamic variation in the region has remained something of a mystery. This video is public domain and can be downloaded at:

MAPS of the earth's gravity

The Potsdam Gravity Potato? Shows Variations in Earth?s Gravity

LAGEOS, GRACE, and GOCE satellites and surface data. Credit: GFZ
People tend to think of gravity here on Earth as a uniform and consistent thing. Stand anywhere on the globe,
at any time of year, and you?ll feel the same downward pull of a single G. But in fact, Earth?s gravitational field is subject
to variations that occur over time. This is due to a combination of factors, such as the uneven distributions of mass in the oceans,
continents, and deep interior, as well as climate-related variables like the water balance of continents, and the melting or growing of glaciers.

The Earth is lumpy. This is a map of Earth’s gravitational field. High areas, colored red, indicate areas where gravity
is slightly stronger than usual, while in blue areas gravity is slightly weaker.
The above map was made in 2005: a more recent and improved version was produced in 2011.
