Climate Change Affects the Birds and the Bees

Climate Change Affects the Birds and the Bees

From plastics invading the Arctic Ocean to the changing morphology of birds in response to rising temperatures and the problems with pathogens killing off pollinators like bees, we examine some of the effects of climate change on Earth’s ecosystems. Plus, Ganymede, moonlight, solar cells, and this week in rocket history, we look back at STS-83.

Theory and Observation Combine to Update Galaxies and Stars

Theory and Observation Combine to Update Galaxies and Stars

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.

Moons May Be Beneficial to Life Beyond Earth

Moons May Be Beneficial to Life Beyond Earth

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.

Rising Oxygen Levels of Past Earth May Help in Search for Life

Rising Oxygen Levels of Past Earth May Help in Search for Life

Scientists analyzed iron-rich sedimentary rocks and estimated the amount of oxygen present in the atmosphere when those rocks formed, finding low levels of oxygen and giving insight into a potential biosignature for life beyond Earth. Plus, controlling robots from space, a SpaceX launch, and this week’s What’s Up.
