COSMIC GLOBE Perhaps space/time is a cosmic globe where its anode and cathode start and end at the same point and all electromagnetic waves reconnect in a closed circuit. 

XRISM’s X-ray Mirror Assemblies were constructed and tested here at Goddard. Now, they are now helping the telescope investigate some of our biggest cosmic questions! Learn more about X-ray mirrors: https://lnkd.in/dnUEhgJA

In the cosmic expanse, countless stars shine brightly, yet many remain unseen, hidden by distance, dust, or simply the limits of our current technology. New creation from Pfeffermouse. #synthwave #retrowave #spacewave

Which of the following describes the South Atlantic Anomaly (SAA)? (a) A region of higher magnetic field strength over the South Atlantic Ocean (b) A region at Earth’s surface with lower magnetic field strength (c) An area with decreased solar activity near the equator (d) A zone of reduced cosmic ray exposure in the Northern Hemisphere

Which of the following describes the South Atlantic Anomaly (SAA)? (a)    A region of higher magnetic field strength over the South Atlantic Ocean (b)    A region at Earth’s surface with lower magnetic field strength (c)    An area with decreased solar activity near the equator (d)    A zone of reduced cosmic ray exposure in the Northern Hemisphere

This week’s flight data - the blue plot shows the effective dose exposure for a commercial flight at ~40,000ft, from Galactic Cosmic Rays (GCRs), during February 2024. The orange plot shows the impact on effective dose rates from a severe Ground Level Enhancement (GLE) event, which can occur approximately once in every 100 years. The resultant effective dose for the whole flight, increases from 14µSv to 175µSv (equivalent to ~35 dental x-rays), due to the GLE event. Part of my research with University of Surrey looks at the radiation hazards from GLEs / space weather and the risk mitigation for very high altitude ‘near space’ flights, and we’ll be publishing a number of papers on this topic in the next few months. #Radiation #Risk #Spaceweather

(CNN) Black hole jets can accelerate radiation and particles close to the speed of light, causing them to glow in wavelengths visible to radio telescopes. https://lnkd.in/g6fdh6g6
