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.
Using data from TESS, a new paper presents evidence for the discovery of thirty potential comets orbiting in the Beta Pictoris system.
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.
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
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. On Mercury.
Remember that new object COW, named for a strange supernova? We’ve seen four more of these Fast Blue Optical Transients, and new research may even have figured out just how and why they occur
An analysis of microscopic features in rocks from which date back between 3.75 and 4.28 billion years, finds evidence of possible microbial life
Data from the Hubble Space Telescope has determined that the newly discovered companion of a star that went supernova had its outer hydrogen layer siphoned off before the explosion. The results support the theory that massive stars generally form and evolve as binary systems
From plastics invading the Arctic Ocean to the changing morphology of birds in response to rising temperatures and the problems with pathogens killing off pollinators like bees, we examine some of the effects of climate change on Earth’s ecosystems.
A ninth-magnitude star in our neighborhood of the Milky Way has been found to contain 65 different elements, including large proportions of heavier elements like gold. This star required either a supernova or a neutron star merger to form.
