Chaos Reigned in Early Solar System

May 26, 2022 | Asteroids, Black Holes (Stellar), Crewed Space, Earth, Exoplanets, Galaxies, Our Solar System, Random Space Fact, Rockets, Space History, Spacecraft, Stars

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

May 25, 2022 | Daily Space, Earth, Fast Radio Bursts, Galaxies, Lucy, Neutron Stars / Pulsars, Planetary Nebulae, Spacecraft, The Sun

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.

Galaxy Used as Cosmic Telescope to Peer Back in Time

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.

Supernova Evidence Found in Comet Fragment

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.

Astronomers Map Interstellar Clouds in Three Dimensions

May 18, 2022 | Astrobiology, Bennu Mapper, Daily Space, Earth, Galaxies, Guest Interview, Nebulae, Rockets, Space China, SpaceX, Starlink

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

May 16, 2022 | Astrobiology, Daily Space, Earth, Exoplanets, Kepler, Mars, Moon, Review, Supermassive Black Holes, Supernovae, Zhurong

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”.
