A satellite will demonstrate an experiment of gravitational reference technologies that will give a better picture of plate movements

GRATTIS will demonstrate the performance of advanced sensors that measure nanometer-scale gravitational changes from space to track movements on Earth's surface and interior

The aurora borealis, a scientific explanation

In this photograph from the SDO Solar Observatory, the lower right area of ​​the Sun is shown in gold on a black background. There are several loops coming down from the sun. Towards the middle is a bright white area - the flare of the sun. Solar flares are powerful bursts of energy. Sun flares and solar flares can affect radio communications, power grids, navigation signals, and pose risks to spacecraft and astronauts.

The aurora borealis was observed in Florida: a strong solar storm is still flooding the earth and is expected to reach another peak tomorrow (Sun)

Space and astronomy

Image: Horsehead Nebula (NASA Webb NIRCam): This image of the Horsehead Nebula, taken by NASA's James Webb Space Telescope, focuses on a portion of the "Horse's Mane" that is about 0.8 light-years across. It was taken using a camera Webb's NIRCam (near-infrared camera) The airy clouds at the bottom of the image are dominated by cold molecular hydrogen. Red streaks extending above the main nebula represent mostly atomic hydrogen gas in this region, known as the photodissociation region and from nearby masses creates a mostly neutral region of gas and dust between the fully ionized gas above and the cooler nebula below. As in many Webb images, distant galaxies are scattered in the background. This image consists of light at wavelengths of 1.4 and 2.5 microns (shown in blue), 3.0 and -3.23 µm (cyan), 3.35 µm (green), 4.3 µm (yellow), and 4.7 and 4.05 µm (red). Credit: NASA, ESA, CSA, K.
