Today’s Travelers in the night goes back in time to tell a story about the discovery of 21 potential hazardous asteroids and Aten asteroids.
December is here & the Last Minute Astronomer bring astronomy to normies and nerds, with little time to spare. We have the naked eye planets visible this month, the lunar phases, and then the meteor shower and other events, so you can plan ahead better than me.
In today’s episode, we’re going to look at everything from how past Earth couldn’t support photosynthesis because the days were just too short, to current Earth letting us get hit by more Cosmic Rays prior to Earthquakes going off, and to supernovae threatening our world while alien stars eat other planets.
The Observer’s Calendar for December from @ActualAstronomy presents spotting Uranus Naked Eye, Catching the Geminid Meteor Showers, see some asteroids while the Moon Pairs with Venus, Mercury, Saturn and Jupiter, and on December 30th we finally get a double shadow transit on Jupiter for everyone in North America!
Today SETI Live discuss about the implications and potential scientific impacts on increased activity on Mars, specifically, human-crewed missions. How will the presence of people on Mars affect the search for past or present life and what planetary protection measures will be required to protect the integrity of scientific research as well as life here on Earth when crews return?
The James Webb Space Telescope has made its first observations of the TRAPPIST-1 system and measured the temperature of TRAPPIST-1b!
Just a warning, the holidays are rapidly approaching. It’s time, once again, to think about what to buy all the space nerds on your lists. Here’s what we like.
The discovery of asteroids, 2016 BA15, the scarier 2016 BY14, and 2013 TX68 which orbit is not well known.
The @cosmicsavannah talk to Professor Travis Rector about how to communicate climate change and why it is important for astronomers to do so.
Each week, when we set off to do this show, we start with one core idea: We want to tell you what is new in space and astronomy… and remember Earth is a planet too.
