Samples From Bennu show evaporative condensates
“An evaporite sequence from ancient brine recorded in Bennu samples”. Nature (2025). https://doi.org/10.1038/s41586-024-08495-6 In a groundbreaking study published in Nature on January 29, 2025, scientists have unveiled remarkable findings from samples collected from the asteroid Bennu. These samples provide unprecedented insights into the early solar system’s chemistry and the potential […]

Millinovae – Discovering a New Class of Stellar Phenomena
Astronomers have identified a new type of celestial event that challenges traditional understanding of white dwarf stars and their explosive behaviour. Dubbed “millinovae,” these phenomena are faint but fascinating, marking an exciting addition to the family of stellar explosions. What Are Millinovae? Millinovae are transient events occurring in binary star […]
Building Planets from “Pebbles”
In a new Paper, published in Nature, published on 22 Jan 2025, on J. Teiser, J., Penner, J., Joeris, K. et al. The growth of super-large pre-planetary pebbles to an impact erosion limit. Nat Astron (2025) investigate how tiny particles in space, called “pebbles,” grow into larger clusters, which are critical in the formation […]
How the Moon’s Origins Challenge Planet Formation Theories
The Moon holds key clues about how Earth and the other inner planets of the Solar System formed. Scientists debate two main theories of planet formation: slow, chaotic growth from planetesimal collisions, or rapid growth by accumulating tiny particles called pebbles. This study explores whether the Moon’s formation can help […]
Do Merging White Dwarf Stars Cause Unique Supernovae in Old Galaxies?

Intelligence, as it may relate to the Fermi Paradox
Humans like to consider themselves the most intelligent animal on Earth, and many argue that is the case because we have built cities, processed metals, built machines, conquered every environment on Earth and now we are starting to explore the deep oceans and space – but does this make us […]
