If our Solar System seems stable, it’s because our short lifespans make it seem that way. Earth revolves, night follows day, the Moon moves through light and shadow, and the

In 1912, astronomer Victor Hess discovered strange, high-energy particles called “cosmic rays.” Since then, researchers have hunted for their birthplaces. Today, we know about some of the cosmic ray “launch

With over 5,000 exoplanets now identified, astronomers have found that our Solar System isn’t the only model of planetary formation. There are super-Earths, sub-Neptunes, hot-Jupiters, and Earth-sized worlds orbiting around

LUNAA Journeys (St. LUcia National Astronomy Association) is looking to address an all too common problem in the global astronomical community. Too often, participation in astronomy is seen as cost

Shortly after astronomers detected asteroid 2024 YR4 on December 27th, 2024, they realized it posed no threat to Earth. But it still might impact the Moon in 2032. The impact

Very massive stars (VMSs), which typically has masses about 100 times that of our own Sun, are critical components in our understanding of the formation of important astronomical structures like

Solar sails are space’s ultimate free ride, they get their propulsion from the Sun, so they don’t need to carry propellant, but they come with their own challenges. A sail

The early universe was shrouded in darkness. Just hundreds of millions of years after the Big Bang, a thick fog of hydrogen gas choked the cosmos, blocking light from traveling

An international team of astronomers using the (https://sites.krieger.jhu.edu/class/) (CLASS) (https://hub.jhu.edu/2025/06/11/telescopes-look-at-cosmic-dawn/) announced the first-ever detection of radiation from the cosmic microwave background (CMB) interacting

We don’t know what dark matter is, but that doesn’t stop astronomers from using it to their advantage. Dark matter is part of what makes gravitational lensing so effective. Astronomers
