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.
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.
With a groundbreaking technique, astronomers have used a galaxy as a gravitational lens to backlight two hydrogen clouds, peering back 11 billion light-years at our early universe. Plus, volcano water on the Moon, a quadruple star system, and this week’s What’s Up takes a careful look at the Sun.
A forensic analysis of the element concentration found in the Hypatia stone finds evidence in the cometary fragment, which may have impacted Earth 28 million years ago, of a supernova origin story. Plus, Ceres, Mars, and this week in rocket history, we look back at SpaceX’s COTS Demo Flight 2.
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.
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”.
