A team of NASA and international scientists succeeded in creating the world’s first galaxy catalyst with data from the Hubble Space Telescope.
The Earth’s atmosphere is severely filtering UV rays. For this reason, it is not possible for astronomers to observe telescopes, stars and galaxies in the face of the Earth. But the Hubble Space Telescope on the atmosphere, in a cosmic sense, can display all the objects of the near universe in detail.
In a project called Legacy ExtraGalactic UV Survey (LEGUS), a team of scientists from different parts of the world managed to create a star and galaxy catalog by bringing together the latest observations of the Hubble Space Telescope with observations in the archives.
The main point here is that it also includes observations of catalytic UV rays. According to Daniela Calzetti of the University of Massachusetts, who led the research, observing stars with UV rays is of great importance in terms of their structure, formation and age.
Elena Sabbi of the Space Telescope Science Institute said that the vast majority of the light in the scene came from stars, but nevertheless the stars do not know exactly what they are doing. Examining the stars with their UV rays is a key quality in terms of learning what they do.
For example; the age of stars we can see without using any tools can range from a million to a few billion. Therefore, in normal opinion, we can not even learn the age of the stars. But when we look at the UV rays that the stars are lying on, we can see that stars ranging in age from 1 to 100 million shine brightly.
