The infographic illustrates the challenges of blood clotting in female astronauts due to microgravity, highlighting faster clot formation, increased stability, and medical monitoring protocols essential for astronaut health.

Just a few days in simulated microgravity can subtly change the way women's blood clots

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.

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.

Scientists have successfully measured magnetohydrodynamic (MHD) turbulence on scales below one parsec

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.

Exploring the concept of the "5,000-Year Ceiling," this infographic delves into the reasons behind the galaxy's silence, highlighting humanity's brief technological age of 200 years and the Fermi Paradox. It illustrates risks such as nuclear war, AI, and climate change that place humanity in a "danger zone," suggesting advanced civilizations might not last beyond 5,000 years.

Where Is Everybody? And yet, no signals. No visitors. No evidence of anyone at all.

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.

The Fermi Paradox and the Search for Cosmic Intelligence

This is the heart of the Fermi Paradox, a term for the profound conflict between the sheer statistical probability that we should be surrounded by evidence of intelligent life and the observed reality of a silent, seemingly empty cosmos. For decades, our telescopes and radio receivers have heard nothing but silence.

M dwarf stars (Red Dwarfs)

When you look up at the night sky, the stars that catch your eye are often giants—luminous, massive beacons similar to, or much larger than, our own Sun. It’s natural to think of these bright points of light as typical. But this perception is a profound illusion.

What New Scar on the Moon Teaches Us?

Despite eons of gazing at the "Man in the Moon," many of us miss the fact that our celestial neighbor is still under construction. While the massive, basin-forming impacts ended billions of years ago, the Moon is still struck by asteroids and comets today. Catching these impacts is a challenge, but thanks to the Lunar Reconnaissance Orbiter Camera (LROC), we can now spot fresh craters that appeared almost overnight.
