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]
Dzerzhinsk (Russian: Дзержи́нск, IPA: [dzʲɪrˈʐɨnsk]) is a city in Nizhny Novgorod Oblast, Russia, located along the Oka River, about 370 kilometers (230 mi) east of Moscow and 35 kilometers (22 mi) west of Nizhny Novgorod.
Russia is back in the business of space observation after losing control of a radio telescope a the start of 2019. The country has successfully launched Spektr-RG, an X-ray telescope co-developed ...
Black hole first observed acting strangely in 2018 The black hole, the official name of which is a mouthful (1ES 1927+654), is located in the distant constellation Draco.
The Event Horizon Telescope (EHT) is a telescope array consisting of a global network of radio telescopes.The EHT project combines data from several very-long-baseline interferometry (VLBI) stations around Earth, which form a combined array with an angular resolution sufficient to observe objects the size of a supermassive black hole's event horizon.
This massive sinkhole measuring 131 feet wide recently opened up about two miles away from a Russian mine. First, flooding stopped operations at the mine about a 1,000 miles east of Moscow.
A black hole with the mass of a car would have a diameter of about 10 −24 m and take a nanosecond to evaporate, during which time it would briefly have a luminosity of more than 200 times that of the Sun. Lower-mass black holes are expected to evaporate even faster; for example, a black hole of mass 1 TeV/c 2 would take less than 10 −88 ...
