Scientists believe the area, known as the Central Molecular Zone, could shed light on the origins of cosmic rays that bombard Earth.
The "presolar grains" were extracted from a meteorite that crashed in Australia 50 years ago.
Studying the the pressure at the edge of the solar system can help us to better understand the influence of the sun on interstellar space.
Scientists used muon radiography to scan a 12 meter building hidden beneath the ground in the fortress of Naryn-Lala.
These supernovae showered the Earth with cosmic rays between around 8 million and 2.6 million years ago, potentially leading to an uptick in lightning strikes and, consequently, wildfires.
Neutrinos and gamma rays may be the "daughter particles" of ultra-high-energy cosmic rays.
The launch depends on good weather, but then it will be smooth sailing 127,000 feet up.
Cosmic rays bombard Earth all the time—here's how scientists used them to explore one of the seven wonders of the world.
Hundreds of scientists worked for over a decade to trace the origin of ultra-high energy cosmic rays.
