Technical information about this photo is available below. This important result is a significant step forward towards the definitive resolution of this long-standing cosmological problem. An image of the Chandra Deep Field South is available at the ESO website on the EIS Image Gallery webpage. . The observed redshift of a distant galaxy or quasar gives a direct estimate of the apparent recession velocity as caused by the universal expansion. The distances indicated in this Press Release depend on the cosmological model chosen and are based on an age of 19,000 million years.
