The crater again contained an active lava lake between 2008 and 2018, with the level of the lava usually fluctuating between 20 and 150 meters below Halemaʻumaʻu's crater floor, though at times the lava lake rose high enough to spill onto crater floor. The lava lake drained away in May 2018 as new volcanic vents opened in lower Puna. The ...

The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2] However, there is some uncertainty regarding its origins [ 3 ] and age, with some sources giving it as < 10 ka [ 2 ] [ 4 ] while the EID gives a broader < 100 ka.
The search for shipwrecks at the bottom of Lake Michigan yielded something scientists weren’t quite expecting: massive craters.. In 2022, researchers with the National Oceanic and Atmospheric ...
More recent evidence suggests the crater is 300 km (190 mi) wide, and the 180 km (110 mi) ring observed is an inner wall of the larger crater. [19] Hildebrand, Penfield, Boynton, Camargo, and others published their paper identifying the crater in 1991. [10] [16] The crater was named for the nearby town of Chicxulub Pueblo. Penfield also ...
[9] [10] [11] In November 2020, evidence of boulder falls was found on the slopes of the delta deposits that the rover is planned to explore, on the wall of Jezero itself as well as on the wall of Dacono, [12] a small crater 2 km (1.2 mi) in diameter on the floor of Jezero. [13] Perseverance successfully landed in the crater on 18 February 2021 ...
Russia's failed Luna-25 mission left a 10-metre wide crater on the moon when it crashed last month after a problem preparing for a soft landing on the south pole, according to images released by NASA.
