Over the weekend of 10–12 May 2024, Earth was struck by the largest solar storm in more than a decade. While many of us enjoyed colourful auroras lighting up Earth’s protective atmosphere, spacecraft had to endure being buffeted by incredibly strong solar winds and electromagnetic radiation.
Positioned between the Sun and Earth, the ESA/NASA Solar and Heliospheric Observatory (SOHO) caught the entire solar outburst on camera. The Sun can be seen spewing out clouds of particles, with an extremely large burst sent to Earth on 11 May. The bright spots on the left and right are Jupiter and Venus.
This video was taken by SOHO’s LASCO instrument, a coronagraph made up of a telescope with a disc blocking the centre of view. By blocking out the direct light coming from the Sun, the instrument can see light from the surrounding corona.
SOHO is not the only ESA spacecraft studying solar activity and space weather. ESA’s Directorates of Science, Human and Robotic Exploration, Earth Observation, Operations, and Technology, Engineering and Quality all have missions and/or other activities directly connected with this topic. Together, they form the ESA Heliophysics observatory or more musically, ESA’s Heliophysics Orchestra.

The next revolution in space technology could be using swarms of small spacecraft working together rather than one much bigger spacecraft. Following an open call for ideas, ESA selected seven projects for mission/system concept study. On 26 April the teams showcased their work in ESA's Concurrent Design facility. Two studies were selected for further development.

Conséquences de l’ #urbanisation pour les #insectes #pollinisateurs et perspectives de mitigation
Des déclins de biodiversités sont observés et les insectes pollinisateurs ne sont pas épargnés. Parmi les pressions environnementales s’exerçant sur les populations de pollinisateurs, les changements d’occupation des sols sont identifiés comme une menace majeure : https://podcastfichiers.college-de-france.fr/porcher-sem-20240216-deguines.m4a
En Europe, l’urbanisation (expansion et densification des zones urbaines) est le changement d’occupation du sol dominant, conduisant à un type d’écosystèmes aux caractéristiques abiotiques et biotiques profondément différentes. En utilisant la littérature nationale et internationale, il est possible de voir comment les communautés d’insectes pollinisateurs sont modifiées dans ces environnements urbains et pourquoi certains s’en accommodent plus que d’autres. Comprendre les réponses des communautés de pollinisateurs permet d’émettre des préconisations et d’envisager des adaptations des espaces urbains afin de les favoriser.
However 95 percent of the sand on #Earth, including the vast sands of the Arabian Peninsula, is unsuitable due to its fine particle size.
This means riverbeds across the world are over-mined, causing pollution and flooding, while also shrinking aquifers and deepening droughts.

Research discussion--The #Secrets #of the #GreatPyramid - #Randall-Carlson - Think Tank - E28
In this episode of Think Tank, Robert hosts #RandallCarlson, a master builder, geometrician, architectural designer, teacher, and "renegade scholar." With over forty years of studying #ancient #mythology and modern #science, #Carlson has been recognized by the National Science Teachers Association for his commitment to science education. His career includes organizing field expeditions to explore and document evidence of catastrophic earth changes. Carlson's life and work emphasize his aspiration to "affect a revival of lost knowledge."
In their relaxed yet insightful conversation, Robert and Randall share their research and ideas, exploring the mysteries of the #Great #Pyramid, sacred geometry, and the intricate relationship between #architecture, #astronomy, and music. Robert highlights the importance of #Metatron's #Cube in understanding ancient structures and demonstrates how the #King's #Chamber walls align with #constellations.
Their discussion uncovers how the #pyramids' geometric layout aligns with musical intervals and astrological constellations, providing a glimpse into sacred geometry and ancient wisdom. They also delve into ancient measurements like the long cubit, the relationship between Euler's identity and light, and the golden ratio. They offer a compelling look into the esoteric knowledge encoded within pyramids and ancient manuscripts. Their casual yet profound dialogue lays the groundwork for future collaborations, capturing the early days of a promising friendship.

Researchers have found the #Pythagorean theorem on ancient #Babylonian clay tablets that predate Pythagoras by 1,000 years! The tablets were discovered in what is now Iraq and date back to the Old Babylonian period (1900-1600 BC). They contain mathematical calculations and diagrams that use the principles of the Pythagorean theorem to solve problems related to land surveying, construction and astronomy.
