We know the universe is expanding, and we have a pretty good idea of how fast it’s expanding, but we don’t know the rate exactly. That’s because of the different methods we have to measure the rate of cosmic expansion keep giving us slightly different results. It’s a nagging problem that bugs astronomers, so while they have worked to ensure current methods are accurate, they have also looked to new ways to measure cosmic expansion. One of these new ways involves gravitational waves.

Astronauts Going to Mars Will Receive Many Lifetimes Worth of Radiation
In a recent study published in Space Physics, an international team of researchers discuss an in-depth study examining the long-term physiological effects of solar radiation on astronauts with emphasis on future astronauts traveling to Mars, to include steps we can take to help mitigate the risk of such solar radiation exposure. The researchers hailed from the United Arab Emirates, New Zealand, India, United States, Italy, Greece, and Germany, and their study helps us better understand the in-depth, long-term health impacts of astronauts during long-term space missions, specifically to Mars and beyond.

The 10 CubeSats hitching a ride to deep space on NASA’s Space Launch System moon rocket promise new discoveries about the moon, space weather, and asteroids. But some of the small spacecraft will launch with their batteries only partially charged after sitting inside the rocket for more than a year.
Samples From Asteroid Ryugu Contain Bits That Came From Outside the Solar System
Long before our Sun began to form, stars were dying in our part of the galaxy. One of them exploded as a supernova. The catastrophe created minute grains of dust and the force of the explosion blasted through a nearby cloud of gas and dust. That action seeded the cloud with “alien” materials from the dead star. The shock wave from the supernova also caused the cloud to collapse in on itself to create the Sun. The “leftovers” of the cloud became the planets, moons, rings, comets, and asteroids of our solar system.
