Ice Mounds Abound in Martian Craters

Apr 1, 2022 | Astrobiology, Daily Space, Earth, Galaxies, Jupiter, Mars, Sky Watching, Stars

An analysis of the thickness and the shapes of the ice mounds in Martian craters found that the patterns matched Mars’ axial tilt and precession over the last 4 to 5 million years. Plus, Europa, faint galaxies, What’s Up, and a review of an entire camera.

Hubble Finds Farthest Star Ever Spotted

Researchers pouring through high-resolution Hubble images of galaxy clusters have found the gravitationally magnified light of a star that was shining just four billion years after the Big Bang, making this bright star the new record holder for the farthest ever spotted. Plus, some launches, ice volcanoes on Pluto, melting Arctic ice, and this week in rocket history, we look back at INSAT.

How Atmospheric Methane Could Be a Sign of Life

Mar 30, 2022 | Astrobiology, Cosmology, Daily Space, Earth, Galaxies, Mars, Planetary Nebulae, Rockets, Space China, Supernovae Remnants, Titan

Join us as we take a deep dive into the history of atmospheric methane on Mars and Titan, how that methane could be a sign of life, and what methane means for future missions and science. Plus, a planetary nebula, a supernova, ancient helium, and a couple of rockets.

ESA’s Gaia Observatory Dates Milky Way’s Evolution

Stellar formation and evolution data collected from ESA’s Gaia telescope has allowed scientists to create a timeline of the evolution of our own galaxy, the Milky Way. Plus, an ancient ice age, sound on Mars, a new exoplanet, and What’s Up.

Rubble Pile Asteroids May Be Extinct Comets

After detecting high levels of organic matter using remote sensors at the asteroid Ryugu, numerical models show that it’s possible that rubble pile asteroids are actually extinct comets. Plus, the Cosmic Optical Background, Enceladus’s tiger stripes, and this week in rocket history, we look back at STS-45.

Earth’s Climate Proves More Resilient Than Thought

Computer models of the effects of an eruption event similar to the Columbia River Flood Basalt show that, despite massive injections of sulfur dioxide into the atmosphere, Earth’s climate rebounded much more quickly than expected. Plus, ORCs, lunar swirls, exoplanets, and diamonds.
