Ryugu samples showing signs of bacteria contamination. Trying to understand the evolution of planets and life is really a driving motivation for a lot of science and science fiction. Landing squarely in the “I think I read a horror story about this,” scientists found that all attempts to prevent earth life from sneaking into a sample of material from the asteroid Ryugu were futile. According to a paper led by Matthew Genge and appearing in Meteoritics & Planetary Science, “the sample was contaminated with microorganisms during the preparation of the polished block” prior to X-ray...
Dino Prints Match Continents
One of the reasons we study the Moon is to help us understand the history of our own planet Earth. The shifting continents and weather patterns of Earth join forces to erase our world’s history. Occasionally, however, our planet reveals its past through the rocks...

Change'e 5 landing site overview. Credit: Chinese National Space Agency's (CNSA) Lunar Exploration and Space Engineering Center On Dec 1, 2020, China landed the Chang’e 5 mission on the near side of the moon. Three days later, that little lander lifted back off with...
Closer Look: Mars is the Future
Since Mars Spirit and Opportunity first set down on Mars in 2004, there has been a continuous robotic presence on the Red Planet. The Phoenix and Insight Landers have answered specific questions about Mars composition and interior, while a small herd of rovers have...
Stonehenge Stones More Geographically Diverse Than Originally Thought
Image credit: Stefan Kühn Before we go, I have a new mystery for you. Researchers, with permission, took a small sample from the altar stone at Stonehenge and examined its composition and structure in a new level of detail. This information made it possible to...
A Star’s Death in Three Acts
While monitoring the sky with optical systems, we’ve found some really weird stuff. Back in 2018, the All Sky Automated Survey for Super Novae discovered a brightening galaxy. Follow -up observations in the X-Ray found the kinds of high energy light that signals a...
Plasma Bubbles Surround Sources of Fast Radio Bursts
In 2007, a student discovered a really weird thing in archival radio data. David Narkevic was working for Duncan Lorimer and found a 5-millisecond burst of energy in the Radio that appeared to be of extragalactic origin. In the years since then, over 100 of these...
Dino-Killer Asteroid Came From the Outer Solar System
A shaded relief image of Mexico's Yucatan Peninsula. NASA/JPL-Caltech. The single messiest day in geologically recorded history was the day the dinosaurs died. On that day, and across the days that would follow, tidal waves wrapped multiple times around our world as...
Missy Elliott’s “The Rain” Gets Beamed to Venus
NASA periodically transmits cultural content into space. From music to a recording of the human heartbeat on Voyager’s golden record, who we are as a planet spanning civilization periodically gets beamed to the stars. And the variety of what is getting sent out just...
Closer Look: Possible Cancellation of NASA’s VIPER Mission
A computer generated concept image of the VIPER rover Throughout this segment, we’re diving into the probable cancellation of NASA’s much anticipated VIPER moon rover. This is an extremely complex topic and a full discussion just isn’t possible given the limited...
When Orbits Go Weird
orbital path of transiting exoplanet TIC 241249530 b As of the day of this recording, Aug 8, 2024, more than 5600 exoplanets have been discovered orbiting more than 4000 alien stars. Within these systems we are regularly finding things our experiences with our own...
