Scientists using Hubble to track storms on Neptune found that a current storm has reversed direction and possibly shed a fragment. Plus, an update on Hayabusa2’s sample return, a non-technological radio emission from an exoplanet, This Week in Sky Watching, and more!

Finding Primordial Ripples Using Gravitational Waves

Dec 11, 2020 | Asteroids, Citizen Science, Cosmology, Daily Space, Earth, Exoplanets, Galaxies, Jupiter, Physics, Saturn, Sky Watching, The Sun

Scientists have found a method to use gravitational waves for understanding the early universe. Plus, an exoplanet with no atmosphere, spiders in space (CW), citizen science, and X-ray bubbles in the Milky Way. And the first of our new weekly segment: This Week in Sky Watching.

Latest Gaia Telescope Data Release Gives More Insight Into Milky Way

Dec 8, 2020 | Asteroids, Book Club, Earth, ESA, Milky Way, Planetary Nebulae, Science, Stars

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!
