Tour of El Gordo Galaxy Cluster | James Webb Telescope By NASA
In July 2022, NASA's James Webb Space Telescope observed El Gordo, a galaxy cluster that existed 6.2 billion years after the big bang. It was selected as the most massive galaxy cluster known at that time in cosmic history. The resulting image reveals a variety of gravitationally lensed galaxies, including striking objects nicknamed the Fishhook and the Thin One. Come with us on a video tour of this new infrared image from Webb.

Water Released from Moon During Meteor Showers | NASA Confirmed
Scientists have discovered that water is being released from the Moon during meteor showers. When a speck of comet debris strikes the Moon it vaporizes on impact, creating a shock wave in the lunar soil. For a sufficiently large impactor, this shock wave can breach the soil’s dry upper layer and release water molecules from a hydrated layer below. The LADEE spacecraft detects these water molecules as they enter the tenuous lunar atmosphere, with peaks in the water signal correlating to known meteor showers on Earth. The discovery of water just beneath the Moon’s surface provides a potential resource for future exploration, and it improves our understanding of the moon’s geologic past and its continued evolution.
