The Kola Superdeep Borehole SG-3 (Russian: Кольская сверхглубокая скважина СГ-3, romanized: Kol'skaya sverkhglubokaya skvazhina SG-3) is the deepest human-made hole on Earth (since 1979), which attained maximum true vertical depth of 12,262 metres (40,230 ft; 7.619 mi) in 1989. [1]
The Xiaozhai Tiankeng is 626 meters (2,054 feet) long, 537 meters (1,762 feet) wide, and between 511 and 662 meters (1,677 and 2,172 ft) deep, with vertical walls. Its volume is 119,349,000 m³ and the area of its opening is 274,000 m 2. This material has been dissolved and carried away by the river.
On Tuesday, July 12, NASA is set to release images from the James Webb Space Telescope, that are truly out of this world. The James Webb Space Telescope is the world's largest and most powerful ...
The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms.
NASA followed this up on Tuesday with more mind-boggling photos from the great expanse of outer space. The "deep field" image gleans a look at a point in space 4.6 billion light-years away from Earth.
A test image captured by NASA's James Webb Space Telescope in May. The dots with six sunbeams stretching outward are stars, while the other sources of light are distant galaxies. (NASA, CSA and ...
A hole in the distribution of galaxies separating Sculptor and Microscopium voids the size of (redshift) 1250 km/s appears to exist. This is roughly 1/2 of Microscopium's diameter. [11] Ophiuchus Void: near 17 h −25° < 5000 km/s (the outer limit) perhaps 0–5000 km/s 25% of average universe density is the void density of matter.
As the race in space was winding down, soviet scientists turned inwards. You'd never guess that this is the site of one of their great achievements. This hard-to-find rusty cap in the ruins of a ...
