Our solar system is currently passing through the Local Interstellar Cloud, a region of highly diluted gas and dust between the stars. On its path, Earth continuously accumulates iron-60, a rare radioactive isotope of iron produced in stellar explosions. This has now been confirmed by an international research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) through the analysis of Antarctic ice tens of thousands of years old...

A mysterious new cosmic pattern discovered by the DAMPE space telescope may finally crack the century-old mystery of cosmic rays. Scientists studying mysterious ultra-powerful cosmic rays have uncovered a surprising hidden pattern that could finally help explain where these particles come from. Using the DAMPE space telescope, researchers found that cosmic ray particles—from tiny protons to heavy iron nuclei—all begin fading away more sharply at the exact same point, hinting at a universal rule governing their behavior across the galaxy.

For more than 100 years, scientists have been trying to understand cosmic rays, incredibly powerful particles that travel across the universe at extreme energies...

Just a few hours before the Orion spacecraft crossed the sky en route to the moon on April 1, mechatronics engineer Rodrigo Trevisan Okamoto received confirmation he had been waiting for since the Artemis 2 mission was announced in 2023. The email from NASA stated that the crew of the first crewed mission to orbit the moon in half a century would carry a device developed by Okamoto and his team at Condor Instruments, a São Paulo-based startup.

“The NASA announcement was sudden and caught us by surprise...

For the first time, scientists have measured the instantaneous mind-blowing power of jets blasting from a black hole.

The jet power from this relatively close black hole-star system is equivalent to 10,000 suns, an international research team reported Thursday. They also tracked the jet speed: roughly 355 million mph (540 million kph)—half the speed of light.

Located 7,200 light-years away, Cygnus X-1 features not only a black hole—the first one ever identified more than a half-century ago—but a blue supergiant...
