"Discovery of 'Old Smoker' Stars Unveils Milky Way's Ancient Secrets"

Astronomers have discovered a new type of star in the Milky Way, nicknamed "old smokers," which exhibit a peculiar puffing behavior. These red giants sit quietly for long periods before suddenly emitting clouds of smoke, a phenomenon never seen before. The discovery was made during a 10-year survey using the VISTA telescope in Chile, initially aimed at finding newborn stars. The stars, located in the Nuclear Stellar Disc near the galaxy's center, are believed to be throwing off puffs of dust for reasons not fully understood, potentially impacting the distribution of heavy elements in the galaxy.

"Discovery of 'Old Smokers': Giant Ancient Stars Unveiled in Milky Way"

Astronomers have discovered a new type of star, nicknamed "old smokers," in the heart of the Milky Way galaxy. These stars exhibit a peculiar behavior of sitting quietly for long periods before suddenly puffing out a cloud of smoke, which temporarily obscures them from sight. The discovery was made during a 10-year survey using the VISTA telescope in Chile, where researchers were initially searching for newborn stars but stumbled upon these mysterious old smokers. The stars, located in the densely packed Nuclear Stellar Disc, could play a significant role in the distribution of heavy elements throughout the galaxy.

Unveiling the Universe's Hidden Secrets: The Zone of Avoidance Exposed

A new study has used infrared observations from the VISTA telescope to search for galaxies within the Zone of Avoidance, the central region of the Milky Way filled with interstellar gas and dust. By analyzing data from the VISTA Variables in Vía Láctea (VVV) survey, the researchers identified 182 galaxies, confirming 75% of the galaxies previously detected by the 2MASS survey. This study marks the first step in uncovering the hidden galaxies in the Zone of Avoidance and paves the way for further exploration using the VVV eXtended Survey.

Unveiling the Hidden Secrets of the Universe's Zone of Avoidance

A new study has used infrared observations from the VISTA telescope to look for galaxies within the Zone of Avoidance, a region in the central part of the Milky Way filled with dust that blocks visible light. By comparing their candidates with data from the 2MASS Extended Source Catalogue, the team confirmed 75% of the galaxies in the region. This initial step opens the door to further study of thousands of galaxies hidden in the Zone of Avoidance, providing a better understanding of the universe.
