Early Bacterial Life May Have Formed Far Earlier Than Thought
An analysis of microscopic features in rocks from the Nuvvuagittuq Supracrustal Belt in Quebec, Canada, which date back between 3.75 and 4.28 billion years, finds evidence of possible microbial life. Plus, a supermassive black hole precursor, temperatures on Neptune, check-ins with various spacecraft, and our weekly What’s Up segment.

Why pulsars shine brightly; Antares’ atmospheric layers; Volcanic craters on Titan
Join us today as we consider a new paper on why pulsars shine so brightly (hint: it’s those pesky magnetic fields). We take a look at new images of Antares’ massive atmospheric layers. Finally, we share a story from our own Planetary Science Institute: evidence has been found that there are volcanic craters on Saturn’s moon, Titan.
Newborn exoplanets cooked by star; Organic molecules appear before stars form; Intelligent life likely throughout galaxy
Join us today as we look at four exoplanets being “cooked” by their star. We discuss a study that reveals that organic molecules existed in the Universe before stars even formed. And we examine a new story on the possibility for intelligent life in our galaxy.
Solar clock; Hubble constant; Universality of Free Fall; Neutron lifetime measurement; Interstellar parallax; Backyard astronomy exoplanet
Join us today as we look at six different astronomy stories. We start with a new clock of solar activity, then talk about three articles on updates to fundamental theories. We follow up with interstellar parallax observations and an exoplanet discovered through backyard astronomy.
Titan moving away from Saturn; Infrared photos of Phobos; Hints of new volcanism in Europe
Join us today as we analyze news that Titan is moving away from Saturn more quickly than previously thought. Also, we look at recent photos of Mars’ moon Phobos taken by NASA’s Mars Odyssey. Finally, we note that there is possibly new volcanic activity underneath Germany. After those stories, we interview Dr. Jamie Molaro from PSI about her recent paper on asteroid Bennu.
Rocket Roundup for June 9, 2020
On Thursday, June 4th at 01:25 am UTC, SpaceX launched yet another batch of sixty Starlink satellites on board a Falcon 9 from SLC-40 at Cape Canaveral Air Force Station.
Another repeating Fast Radio Burst; Finding a missing “hot corino”; Prebiotic molecules in icy dust grains
Join us today for a story on another repeating fast radio burst. We talk about hot corinos and how one that went missing is now found. And we discuss research that shows evidence for prebiotic molecules in tiny dust grains covered in ice.
