Pulsars as the Particle Accelerators of the Universe

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

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.

Astronomers Map Interstellar Clouds in Three Dimensions

Astronomers Map Interstellar Clouds in Three Dimensions

A team of scientists combined stellar locations from the Gaia mission with dust and cloud maps from the WISE and 2MASS catalogs to create amazing three-dimensional images of the California Cloud and Orion A Cloud. Plus, rocket launches, the origin of carbon, and an interview with Dani DellaGiustina, principal investigator for the OSIRIS-APEX mission.

Plants Successfully Grown in Lunar Soil

Plants Successfully Grown in Lunar Soil

Using a mere twelve grams of lunar soil returned by the Apollo missions, scientists have successfully grown plants in the lab. With a wealth of genetic data on hand, they can now analyze the changes to the plants and the soil. Plus, stellar cannibalism, a black hole merger, brown dwarfs, water on Mars, and a review of “Star Trek: Strange New Worlds”.
