Chaos Reigned in Early Solar System
Researchers using radioactive decay analysis have recreated the early history of some asteroids in our solar system, revealing a more chaotic phase than previously thought. Plus, a near-Earth asteroid, a trove of black holes, and this week in rocket history, we look back at Mercury-Atlas 7.

Six Star Eclipsing System Found in TESS Data with AI Help
A new system has been found that consists of six stars in three binary pairs, which are producing a bevy of eclipses with each other. They were found in TESS data with the help of machine learning. Plus, Venus, more exoplanet news, difficulties with the record of early life, and a look back at Marie Tharp’s groundbreaking work.
Scientists Narrow Potential Mass Range of Dark Matter
Dark matter is only acted upon by the force of gravity according to new research, which constrains the potential range of mass for the elusive particles. Plus, how precipitation affects the Earth’s crust, a pair of ancient asteroid impacts in Germany, NASA’s Day of Remembrance, and this week’s What’s Up.
Rocket Roundup for January 27, 2021
Join us for this week’s Rocket Roundup with host Annie Wilson as we look back at the launches that happened over the last week, including one Rocket Lab and two SpaceX… wait, more Starlink? *checks notes* Yes, more Starlink.
Six-Exoplanet System in Resonance, Challenges Formation Theories
It’s a day ending in ‘y’, and planetary formation theories are once again being challenged. This time the challenge comes from a six-planet system with five planets in resonance. Plus a cloudless Jupiter, TRAPPIST-1, volcanoes, and some science of the weird.
Explore Gravitational Wave Events in Interactive Graphic
A data visualization designer has created an interactive graphic that allows us to explore all 50 gravitational wave events recorded to date, and some even have sounds! Plus, blue jet lightning and all the planetary science stories we can handle. Happy Friday!
