Galaxies from the early Universe are more like our own Milky Way than previously thought, flipping the entire narrative of how scientists think about structure formation in the Universe, according to new research published today.
The Milky Way is a typical 'disk' galaxy, which a shape similar to a pancake or compact disk, rotating about its centre and often containing spiral arms. These galaxies are thought to be the most common in the nearby Universe and might be the types of galaxies where life can develop given the nature of their formation history.
It was once thought that disk galaxies such as the Milky Way were relatively rare through cosmic history, and that they only formed after the Universe was already middle aged.

If You Could See Gravitational Waves, the Universe Would Look Like ThisOur biology limits our vision. Our eyes can only perceive specific wavelengths of light. But what if we could see the Universe in gravitational waves? A new NASA simulation mapped out hundreds of collisions between dense objects, like white dwarfs, neutron stars, and black holes. These collisions happen within galaxies, sending ripples of gravitational waves across the Universe, and would allow astronomers to recreate the shape of galaxies over time. Upcoming observatories will detect tens of thousands of ultra-compact binary stars, providing even higher resolution—an entirely new way to observe the Universe.

Astronomers discover newborn galaxies with the James Webb Space TelescopeWith the launch of the James Webb Space Telescope, astronomers are now able to peer so far back in time that we are approaching the epoch where we think that the first galaxies were created. Throughout most of the history of the universe, galaxies seemingly tend to follow a tight relation between how many stars they have formed, and how many heavy elements they have formed.
