NASA Orbiter Discovers Rare 'Century Crater' on the Moon
Quick Brief
While conducting a routine data-quality check using NASA's Lunar Reconnaissance Orbiter, a scientist spotted an unusual bright spot surrounded by a dark halo on a digital lunar map. This visual anomaly revealed a rare, massive new crater formed on the lunar surface. The discovery points to a significant impact event of a scale rarely seen in a century.
What Happened?
A NASA scientist examining a giant Moon map on a computer screen noticed an unusual bright spot encircled by a dark halo. This signature indicated that surface material had been significantly disturbed, leading to the identification of a new, exceptionally large impact crater on the Moon.
Why It Matters
Discoveries of this magnitude provide rare insights into the frequency and scale of major impacts occurring on the lunar surface. Such 'once-in-a-century' events help scientists better understand planetary impacts and the ongoing evolution of the Moon's geology.
Key Facts
- The discovery was made by Robert Wagner, a scientist working with NASA's Lunar Reconnaissance Orbiter (LRO).
- It was initially spotted during a routine data-quality check of a giant Moon map.
- The feature appeared as an unusually large bright spot circled by a dark halo.
- The halo and brightness implied that surface material in the area had been intensely shaken up.
- The impact has been characterized as a rare, 'once-in-a-century' lunar crater.
