Neutrinos are slippery little buggers, and a new experiment is tightening the net to pin down their itsy-bitsy mass. Closer to home, the Earth's core is a complicated system with changing rates of rotation. We also take a look at the peculiar rings of a distant cometary body, Chariklo, thanks to a new observation by...

Scientists have created a simulation of a wormhole in a quantum computer. Top quark helps us understand the significance of this as well as reminds us what the heck a wormhole is anyway. In planetary science, collisions may once again come to the rescue to help explain a mystery. This one is the odd gap in exoplanet...

Our own solar system is lacking in one of the most common types of planet, the Super Earth. These large rocky planets have a cookie-cutter characteristic that may be explained by the evolution of stuff in a forming system’s disk. Speaking of disks, a mystery about the Milky Way its family of satellite galaxies seems...

Top quark Jim Cooney rejoins the crew and gives us a deep dive into the breakthrough in nuclear fusion at the National Ignition Facility. Mars rover Perseverance is busy storing samples of Mars for a future mission to bring home, and the Sun may have a 17-year cycle in addition to the well-known 11-year cycle. Ring in...
