Aero-News Quote of the Day

“This first observation of this isotope in a star-like object is also important in the broader context of galactic chemical evolution. This is the first time an active producer of the radioactive nuclide aluminum-26 has been directly identified.”

Source: Tomasz Kaminski (Harvard-Smithsonian Center for Astrophysics, Cambridge, USA), commenting on astronomers using ALMA and NOEMA having made the first definitive detection of a radioactive molecule in interstellar space. The radioactive part of the molecule is an isotope of aluminium. The observations reveal that the isotope was dispersed into space after the collision of two stars, that left behind a remnant known as CK Vulpeculae. This is the first time that a direct observation has been made of this element from a known source. Previous identifications of this isotope have come from the detection of gamma rays, but their precise origin had been unknown.
