1. The Vera C. Rubin Observatory on Monday released its first dazzling images of deep space in a preview of the cosmic movie the pioneering probe was built to create. Over the next decade, the observatory will photograph the entire southern cosmos every three to four nights, snapping ultra-high-definition images at 30-second intervals. Each photo will cover an area the size of 45 full moons, and in the coming years, each swath will be captured up to 1,000 times. Together, the photos will create a dynamic time-lapse record of the southern sky—essentially a vast celestial flipbook that is expected to document 38 billion objects, from galaxies and stars to black holes and supernovae. The project, dubbed the Legacy Survey of Space and Time, is slated to begin later this year. It will advance four science goals: inventorying the solar system, mapping the Milky Way, cataloging billions of transient space objects and unlocking the mysteries of dark matter and dark energy. No previous telescope has peered this far and wide into space. (Sources: rubinobservatory.org, wsj.com)

2. One big question:

According to two Israeli officials with knowledge of the intelligence, Iran moved material away from the sites before they were attacked, including 400 kilograms, or roughly 880 pounds, of enriched uranium. Senior U.S. officials concede they did not know the fate of Iran’s stockpile of near-bomb-grade uranium.

This month, Iran also claimed that it had another enrichment site “in a secure and invulnerable location.” Experts think the new site is likely south of Natanz, under Kuh-e Kolang Gaz La, a mountain nearly a mile above sea level. That means it could be buried nearly twice as deep as the Fordo site. (Source: nytimes.com)
