Astronomers have discovered a new type of star, dubbed "old smokers," near the center of the Milky Way galaxy. These aging, giant stars remain inactive for decades before emitting clouds of smoke and dust, potentially influencing the distribution of elements across the universe. The discovery was made during a decade-long survey involving the monitoring of nearly a billion stars in infrared light, leading to the identification of these previously hidden stellar objects. Further research is needed to understand the process behind the release of dense smoke and its impact on the spread of heavy elements in the galaxy.

These aging, giant stars remain inactive for decades before emitting clouds of smoke and dust, potentially playing a role in distributing elements across the universe. The discovery was made during a decade-long survey involving monitoring nearly a billion stars in infrared light, revealing not only the old smokers but also newborn stars and unusual changes in luminosity among red giant stars. This unexpected finding could have wider significance for understanding the spread of heavy elements in the Milky Way's nuclear disc and other galaxies.

These aging, giant stars remain inactive for decades before emitting clouds of smoke and dust, potentially playing a role in distributing elements across the universe. The discovery was made during a decade-long survey involving the monitoring of nearly a billion stars in infrared light, revealing not only the old smokers but also newborn stars undergoing outbursts. The old smokers, found in the innermost nuclear disc of the Milky Way, are shedding light on the process of element release from aging stars and its impact on the formation of new stars and planets.

Astronomers have discovered a new type of aging, giant stars near the heart of the Milky Way galaxy, dubbed "old smoker" stars, which remain inactive for decades before emitting clouds of smoke and dust. These stars were identified during a decade-long survey involving the monitoring of nearly a billion stars in infrared light, revealing their unexpected behavior and potential role in distributing elements across the universe. The discovery could have wider implications for understanding the spread of heavy elements in the Milky Way's Nuclear Disc and metal-rich regions of other galaxies.
Water that existed on the parent of asteroid Ryugu has influenced the distribution of elements on the asteroid, according to a study. Researchers compared isotopes of chromium and titanium and found that the ratios between isotopes of chromium varied significantly, suggesting exposure to water. The findings indicate that water circulated on Ryugu's parent body, influencing the asteroid's chemical history before it broke away. This study aligns with previous research that also found evidence of water on Ryugu's parent body.
