New research presented at the Workshop on Terrestrial Analogs for Planetary Exploration used the Haughton impact crater in Arctic Canada as a potential analog for impact craters on Titan, one of the targets of the upcoming Dragonfly mission. Plus, giant spinning structures, the slowing of the Milky Way, a blinking star, and volcanoes here on Earth.
New research shows that our galaxy was already in place prior to a major collision with a dwarf galaxy ten billion years ago. Plus, meteor showers, fast radio bursts, tardigrades, climate change, and a science review of Godzilla vs. Kong. No. Really!
Gamma rays given off by fourteen different sources in our sky could be a sign of the existence of antistars, leading to the potential for breaking the standard cosmological model. Plus, nano dust, the HI-SEAS experiment, hydroxyl at an exoplanet, and this week’s What’s Up.
A new study examines the formation of rocky worlds from dust particles containing ice and carbon, increasing the possibility that our own Milky Way galaxy could be filled with aquatic planets similar to Earth. Plus, a simulation of the Milky Way-Andromeda collision and an overview of asteroid Apophis.
While searching for an intermediate-mass black hole, scientists instead found a cluster of smaller black holes in the globular cluster NGC 6397. Plus, supernovae, meteorites, and an interview about mapping water ice on Mars with guests Gareth Morgan and Than Putzig from the Planetary Science Institute.
The release of the Gaia space telescope’s Early Data Release 3 has paved the way for a 3D map of the Milky Way, a glimpse at its history, and the acceleration of our own solar system. Plus, Alaskan volcanoes, the Stingray Nebula fades, and yes, that really was a Centaur rocket booster captured by the Earth. And we announce our first CosmoQuest Book Club selection!
