Most lunar meteorites are launched from the Moon by impacts making lunar craters of a few kilometers in diameter or less. [6] No source crater of lunar meteorites has been positively identified, although there is speculation that the highly anomalous lunar meteorite Sayh al Uhaymir 169 derives from the Lalande impact crater on the lunar ...
As they streak through the sky, glowing, hot air around the meteors gives the meteors the appearance of shooting stars. During meteor showers, many meteors travel through Earth's atmosphere over a ...
During the 1960s, rectified images of Mare Orientale by Gerard Kuiper at the Lunar and Planetary Laboratory gave rise to the notion of it being an impact crater. [3] [4] The structure, with the flat plain of the mare in the center, is about 900 kilometres (560 mi) across and was formed by the impact of an asteroid-sized object, [5] [6] possibly 64 km (40 mi) in diameter and travelling at 15 km ...

In a breathtaking celestial event that captivated thousands, a meteor streaked across the night sky, leaving spectators in awe from Puerto Rico to the Dominican Republic. The dazzling sight, which ...
Lunar craters as captured through the backyard telescope of an amateur astronomer, partially illuminated by the sun on a waning crescent moon. Evidence collected during the Apollo Project and from uncrewed spacecraft of the same period proved conclusively that meteoric impact, or impact by asteroids for larger craters, was the origin of almost ...
The next full moon is due to appear this week in night skies all over the world. When it emerges, the phenomenon will hold a couple of notable titles.
