Exploring the Geminga Pulsar: This infographic highlights a groundbreaking discovery in cosmic-ray physics, showcasing the Geminga halo's 100 TeV electron cutoff and its role in understanding particle diffusion and magnetic turbulence. Located 800 light-years away, Geminga provides an ideal laboratory for cosmic-ray propagation studies with a detection range from 16 TeV to 250 TeV.
Just a few days in simulated microgravity can subtly change the way women's blood clots, sparking bigger questions about health monitoring protocols for astronauts who spend six months or more in orbit.
First reported in 2020, an International Space Station (ISS) mission detected an unexpected blood clot in a female astronaut's jugular vein.
For the first time, scientists have successfully measured magnetohydrodynamic (MHD) turbulence on scales below one parsec within the gamma-ray halo surrounding the Geminga pulsar wind nebula.
Published in Science Advances, this groundbreaking observation extends to the highest energies—above 100 tera-electron volts (TeV)—providing entirely new insights into the behavior of cosmic rays and magnetic fields within the Milky Way.
It is one of the most famous questions in science, asked over lunch by physicist Enrico Fermi. With hundreds of billions of stars and billions of years, life should have emerged many times over. And yet, no signals. No visitors. No evidence of anyone at all.
The universe is 13 billion years old. Our galaxy alone contains hundreds of billions of stars, a significant proportion of which host planets. Many of those planets sit in the right temperature range for liquid water.
