The Quest for Absolute Zero

🥶 Beyond Absolute Zero: The Science of Ultracold Matter 10 sources This research paper details astronomical observations of the Boomerang Nebula, recognised as the coldest location in the known universe. By utilizing the ALMA telescope and Hubble Space Telescope imagery, scientists examined the nebula’s bipolar structure, which consists of hollow cavities and a dense central waist. The study confirms that the nebula is a pre-planetary entity formed by a star's massive loss of weight during its final evolutionary stages. Findings indicate that the ultra-cold outflow is expanding at varying speeds, causing it to cool below the temperature of the cosmic microwave background. Furthermore, the researchers identified millimetre-sized dust grains within the nebula's core, suggesting that grain coagulation occurs much earlier in a star's life cycle than previously thought. Overall, the data provides a clearer understanding of the physical properties and thermal history of this unique celestial object.
