The ALPINE program, which conducted the study, uses data obtained from 70-hour
A study of the objects in ultraviolet and radio wavelengths showed that they are spiral galaxies and formed approximately 1-1.5 billion years after the Big Bang.
Tracing the signature of a positively charged formcarbon C+, scientists were able to observe the rotation of galaxies. Observations have shown that 15% of them are ordered spiral galaxies that formed during the period of active development of the Universe - previously it was believed that such objects could not exist at this time.
"We found well-orderedrotating galaxies that existed at a very early and rather stormy stage of the development of the Universe. This means that they must have formed through a smooth gas collection process and did not collide with other galaxies, as many other galaxies do."

The previously smooth edge of the disk of the Sombrero Galaxytold scientists about her turbulent past. Observations using the Hubble telescope allowed scientists to suggest that in the past the object survived a merger with another large galaxy.
