Almost 50 years old, the Voyager 1 space craft now traveling through Interstellar space continues to operate, but maybe showing signs of dementia! 😜 In short - the space craft is acting "weird". https://discoverwildscience.com/voyager-1-keeps-sending-strange-data-from-interstellar-space-and-scientists-are-baffled-1-406760/ #Space #SpaceExploration #Voyager1 #NASA #SpaceCraft #IntersellarSpace #CosmicRays #Experiment

#Radiation measurements on a recent #flight I was on, it is interesting to see that immediately after takeoff, the rate drops significantly and only goes up higher again once you gain altitude. I guess it's due to the proximity to the ground and all that concrete and #rock #geology near the surface and then the #CosmicRays in the upper #atmosphere.

There was one #HighEnergy event on the next flight. Probably due to a cosmic ray.

Studies reveal that galactic cosmic rays and solar particle events damage lens cells, increasing cataract risk decades earlier than normal. Learn how radiation disrupts DNA, accelerates lens opacification and why astronaut eye health is a critical challenge for deep-space exploration.

Cosmic rays carry antiparticles, primarily positrons and antiprotons, produced by high-energy collisions in the interstellar medium. The Alpha Magnetic Spectrometer (AMS-02) aboard the International Space Station detects these particles.

Excited to share my first #SpaceAustralia feature article for 2026 about an exciting and ambitious project that is unfolding 1km below the surface in regional Victoria.

Last year, I had the incredible opportunity to visit the Stawell Underground Physics Laboratory (SUPL) with Dr Katie Mack and explore the ambitious efforts of the SABRE South experiment. Shielded from cosmic rays by a kilometre of rock, this lab offers the ideal conditions to search for the faint whispers of dark matter, which still accounts for 25% of all matter in the Universe—and yet remains completely undetected.

Check out the article (and yes, check out our funky boots in the clean room!) and keep a lookout for exciting news of the detectors switching on later in 2026.

Ice on Mars might be nice for building domes, but it will not protect humans from high‑energy galactic cosmic rays which is the dominant form of radiation hitting the surface of Mars. Then there are the occasional solar particle events... can you say instant sun burn!

The mysterious black fungus from Chernobyl that may eat radiation.

Mould found at the site of the Chernobyl nuclear disaster appears to be feeding off the radiation.

Could we use it to shield space travellers from cosmic rays?

As this week's major geomagnetic storm subsides, the Forbush Decrease (reduction in galactic cosmic rays caused by the CME bow-shock) is still having an effect as it spreads out into the solar system.

The Oulu neutron monitor is still registering a rate around 10% lower than the background rate over the last month.
