Galaxy at redshift z=8.6 (the actual paper)

In summary, the paper published in Nature magazine yesterday discusses the discovery of a 13.1 billion-year-old galaxy, captured in a "baby picture" taken by the European Southern Observatory when the universe was only 600 million years old. This is considered a significant and impressive achievement.

Good show ESO!

Galaxy is now 3.1 billion years old. The baby picture that European Southern took of it is when the universe had been expanding for only 600 million years.

I presume there's a 1 missing there, and the galaxy is now 13.1 billion years old.

This is pretty amazing stuff. Thanks for the link -- sylas

1. What is the significance of the galaxy at redshift z=8.6?

The galaxy at redshift z=8.6 is significant because it is currently the most distant known galaxy from Earth, with a redshift that corresponds to a distance of approximately 13 billion light years away. This means that we are observing this galaxy as it was when the universe was only about 600 million years old.

2. How was the galaxy at redshift z=8.6 discovered?

The galaxy at redshift z=8.6 was discovered using the Near-Infrared Camera and Multi-Object Spectrometer (NICMOS) on the Hubble Space Telescope. By observing the galaxy in near-infrared light, which is less affected by dust and gas in the universe, researchers were able to detect the distant galaxy.

3. What information does the galaxy at redshift z=8.6 provide about the early universe?

The galaxy at redshift z=8.6 provides valuable information about the early universe, including the formation and evolution of galaxies. Its distance and redshift indicate that it formed during the reionization epoch, a time when the universe was transitioning from a neutral state to a state dominated by ionized gas. Studying this galaxy can help us better understand the processes that drove this transition.

4. How does the galaxy at redshift z=8.6 compare to other distant galaxies?

The galaxy at redshift z=8.6 is one of the most distant galaxies ever observed, but it is not the only one. Other galaxies at similar redshifts have also been discovered, but this particular galaxy stands out because of its brightness in the near-infrared. This brightness allows for more detailed observations and measurements, providing a better understanding of its properties and role in the early universe.

5. What are the future implications of studying the galaxy at redshift z=8.6?

Studying the galaxy at redshift z=8.6 and other distant galaxies can help us further our understanding of the early universe and the processes that drove its formation and evolution. It can also provide insights into the origin of the elements and structures we see in the universe today. Additionally, studying these distant objects can help us improve our observational and theoretical techniques, leading to advancements in astronomy and cosmology as a whole.
