Abstract: The Dark Energy Spectroscopic Instrument (DESI) collaboration 
presented results from the data release 2 (DR2) corresponding to the 
first three years of observations. These results represent a significant 
improvement over the previous Baryon Acoustic oscillations (BAO) 
analysis from the first yer of observations (DR1). DR2 covers a 
significantly larger cosmic volume and a more comprehensive analysis was 
performed of the combination with external datasets such as uncalibrated 
supernovae and cosmic microwave background data. I will give an overview 
of the DESI survey and present cosmological interpretation of the DR2 
BAO data.
