Do you want lasers? I want lasers! And today’s show features lots of lasers. We also have more questions than answers about Mars’ methane, misbehaving stars, and new research on how we would look for the early signs of life on other worlds. Plus, a study on how spaceflight impacts the human brain.
Today, we bring you stories proving that we do understand some things, like black holes, and that we have forgotten other things, like that the Earth’s crust can sag under the weight of ice. It’s all a lot more complicated than we like to think. But it sure is pretty, and when the science makes your head hurt, our What’s Up segment will fill your eyes with some beauty.
Today, our view on the universe gets itself an update thanks to the combined efforts of theorists and observers. From a new understanding of how galaxies can lose their dark matter, to how white dwarfs can be resurrected into helium-burning stars, we have the weird, the wonderful, and in the case of a new lunar tracking system, we even have a touch of the mundane. Plus, this week in rocket history, we look back at STS-82 which serviced the Hubble Space Telescope.
Observers tracking a piece of space debris that is expected to impact the far side of the Moon early in March have now corrected the origin of the object, which isn’t from SpaceX but is from a Chinese Long March 3B involved in the Chang’e 5TI mission. Plus, asteroid 16 Pysche, craters in Wyoming, more launches, and an interview with Katharine Hesse from the TESS mission.
The second stage of a Falcon 9 rocket launched in 2017 re-entered the atmosphere over Mexico, breaking up and creating a show of fiery lights in the sky. Plus, dead stars with possibly living planets, more on moon formation, more launches, more launch failures, and a review of “The Apollo Murders” by Chris Hadfield.
Defying expectations, an ultramassive galaxy and many of its cluster companions had already formed most of their stars and become inactive only two billion years after the beginning of the universe. Plus, the nightside of Venus, a new exoplanet for Proxima Centauri, and What’s Up.
