According to astronomers how many galaxies are distributed across the observable universe 51 trillion several thousand one billion

Astronomers estimate that there are about 100 billion to 200 billion galaxies in the observable universe. Some estimates have gone higher, suggesting there could be up to 2 trillion galaxies when considering smaller and fainter galaxies that may have been missed in earlier observations. Therefore, the figure "51 trillion" is significantly higher than current estimates. So, the most widely accepted number remains in the range of 100 billion to 2 trillion galaxies.
