New Imaging Techniques Unveil Vast Galactic Halos

Groundbreaking observations reveal the extensive gas clouds that envelop galaxies, offering new insights into their evolution and interactions.

Scientists used the Keck Cosmic Web Imager to capture detailed images of galaxy halos extending 100,000 light years into space.
The circumgalactic medium, containing up to 90% of a galaxy's normal matter, plays a crucial role in galaxy formation and evolution.
The study found a clear boundary between the interstellar medium and the circumgalactic medium, challenging previous assumptions.
These findings suggest that the halos of the Milky Way and Andromeda are already interacting.
The research highlights the importance of advanced spectrographs in uncovering the mysteries of the universe.
