"First-Ever Observation of an Extragalactic Star's Disc Marks Cosmic Breakthrough"

Astronomers have discovered the first evidence of a rotating disc of material around a massive young star in a neighboring galaxy, the Large Magellanic Cloud, using the Atacama Large Millimeter/submillimeter Array (ALMA). This breakthrough provides insight into the formation of high-mass stars and suggests that they form in a similar way to lower-mass stars. The discovery, led by a team including Rice University's Megan Reiter, sheds light on the early universe and offers a glimpse into how stars and planets formed in the past.

Extragalactic Star Spotted Orbiting Milky Way's Black Hole

A star named S0-6, located near the center of the Milky Way, is believed to have originated from a galaxy that no longer exists. This interloper star could have traveled over 50,000 light years to reach the supermassive black hole at the heart of our galaxy. The star's composition suggests it came from smaller galaxies outside the Milky Way. This discovery could help explain the mystery of how stars near the black hole are formed. Further investigation will be conducted to confirm the star's origin and determine if it traveled alone or with companions.

"Possible Extraterrestrial Presence Detected in Orbit around Milky Way's Black Hole"

Astronomers have potentially discovered an extragalactic star, named S0–6, among the stars orbiting the supermassive black hole at the center of the Milky Way, Sagittarius A*. The star's chemical composition suggests it originated in a small satellite galaxy of the Milky Way that was cannibalized billions of years ago. If confirmed, this would make S0–6 the first extragalactic star found near Sgr A*. Further investigation is needed to unravel the mysteries of these stars near the supermassive black hole.

"Unveiling the Epic Odyssey: A 10-billion-year Trek to a Distant Black Hole"

A new study reveals that a star located near the supermassive black hole at the center of the Milky Way galaxy originated from outside the galaxy, marking the first time an extragalactic star has been found in the vicinity of a supermassive black hole. The star, known as S0-6, is estimated to be 10 billion years old and has a chemical composition similar to stars found in small galaxies outside the Milky Way. Researchers suggest that S0-6 was likely born in a now extinct small galaxy that was absorbed by the Milky Way, providing observational evidence that some stars near supermassive black holes formed outside their host galaxies.

First-Ever Planet-Forming Disk Found Beyond the Milky Way

Astronomers have discovered a young star, HH 1177, outside the Milky Way galaxy that is surrounded by a dense disk where planets may form. This unprecedented find in the neighboring dwarf galaxy, the Large Magellanic Cloud, could provide valuable insights into star and planet formation. The star's disk was observed using the ALMA telescope, and its presence was confirmed by measuring the movement of dense gas around the star. This discovery marks the first direct evidence of an extragalactic accretion disk, shedding light on the formation of stars and planets in other galaxies.
