Astrochemistry, the study of elements and molecules in space, is a fascinating and expanding field that not only informs our understanding of the universe but also has practical applications on Earth. This interdisciplinary field combines aspects of astronomy, chemistry, and physics to explore the composition of the cosmos and the processes that shape it. By examining the universe’s chemical makeup, astrochemists can piece together the ancient origins and evolution of galaxies and stars and inform our search for extraterrestrial life. A Brief History of Astrochemistry The first steps towards astrochemistry took place in the early 20th century after the discovery of cosmic rays. Cosmic rays are highly energetic particles that travel through space and interact with matter, ionizing and exciting atoms and molecules as they go. During the 1920s and 30s, theorists proposed that cosmic rays might be responsible for a range of chemical reactions in space, leading to the formation of molecules...

Cosmic rays have been one of the most fascinating subjects in space physics for decades. These high-energy particles that pervade the universe are believed to originate from explosive events such as supernovae, gamma-ray bursts, and active galactic nuclei. However, despite decades of study, the exact mechanisms that give rise to cosmic rays and their behavior in the cosmos remain shrouded in mystery. Dark matter, on the other hand, is another enigma of the universe. It is the invisible, elusive substance that is believed to make up almost 85% of the universe's matter. Dark matter does not emit, absorb, or interact with electromagnetic radiation, making it undetectable by traditional telescopes and other astronomical instruments. For many years, scientists have been curious about the potential link between cosmic rays and dark matter, and how the two might interact with each other. In recent years, technological advancements and new discoveries have allowed astronomers and physicist...
