Understanding Space with Gaia Data Release 3

Jun 15, 2022 | Active Galaxies, Daily Space, ESA, Galaxies, Rockets, Science, Spacecraft, SpaceX, Stars, White Dwarfs

The Gaia mission released its third ‘treasure trove’ of observations and calculations of more than two billion stars in the Milky Way, including ‘starquakes’, stellar DNA, binary star systems, and more. Plus, day one of the American Astronomical Society press conferences and updates on Starship and NASA’s TROPICS-1 mission.

New Method Finds Four Brown Dwarfs

A second repeating fast radio burst was detected in 2019 by China’s FAST observatory and confirmed in 2020 by the Very Large Array. This latest discovery raises the possibility that there are two different types of FRBs. Plus, a SpaceX commercial launch, mission updates, neutron stars, and this week’s What’s Up.

Researchers using radioactive decay analysis have recreated the early history of some asteroids in our solar system, revealing a more chaotic phase than previously thought. Plus, a near-Earth asteroid, a trove of black holes, and this week in rocket history, we look back at Mercury-Atlas 7.

Pulsars as the Particle Accelerators of the Universe

Fast, strong magnetic winds caused by quickly rotating pulsars may be accelerating particles like electrons to extremely high-energy states and creating gamma-ray photons in their wake. Plus, missions close to home, large and distant objects, some pretty Hubble photos, and laser simulations of fast radio bursts.

Hubble Observations Make For a More Precise Hubble Constant

Over the past three decades, astronomers around the world have been using the observations of the Hubble Space Telescope to more precisely calculate the expansion of the universe. And they have converged on a precision of just over 1%. Plus, Boeing launches Starliner, Voyager 1 struggles, and Erik reviews his favorite camera lens.
