Today’s science stories run the gamut of the strange and the weird, with several black holes, the effects of space on astronaut blood cells, and how alligator mating dances added to solar science. Plus, this week’s What’s Up helps you choose binoculars for sky gazing.
As we return from our mini-break, we bring you some highlights of stories that happened while we were away, including black holes spiraling toward each other, the possible origin of a fast radio burst, and more information on the demise of the dinosaurs. Plus, Erik Madaus brings us updates on quite a few rocket launches.
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.
New simulations find that to form a moon with a similar size ratio to our own system, certain types of planets are needed. And that type of moon-planet system could then be beneficial to the rise of life on the planet. Plus, a Starlink launch, puffy planets, and training astronauts underwater for spacewalks.
NASA’s Curiosity rover has discovered carbon isotopes on Mars which are usually caused by the degradation of biological methane, leading scientists to examine other potential reasons for the molecules. Plus, more Starlink satellites, their impact on observing, and This Week in Rocket History.
China’s Chang’e-5 lunar lander has made the first in situ detection of water on the Moon, using reflectance spectroscopy from the surface of our natural satellite. Plus, all the news from the AAS virtual press conferences, including black holes and galaxies.
