The conversion of gravitational potential energy to radiation by infalling to a black hole converts between 6% and 32% of the mass to energy, compared to 0.7% for the conversion of mass to energy in a star like the Sun. [40] It is the only process known that can produce such high power over a very long term.
Discovered through gamma-ray burst mapping. Largest-known regular formation in the observable universe. [8] Huge-LQG (2012–2013) 4,000,000,000 [9] [10] [11] Decoupling of 73 quasars. Largest-known large quasar group and the first structure found to exceed 3 billion light-years. "The Giant Arc" (2021) 3,300,000,000 [12] Located 9.2 billion ...
But unlike the jet formed by J1601+3102, Porphyrion was found 7.5 billion light-years away from Earth in what’s called the “nearby” universe, rather than the early universe, according to the ...
The scientists discovered an object 15,000 light-years from Earth in the Scutum constellation. The object, dubbed GPM J1839−10, released radio waves every 22 minutes. The bursts of energy lasted ...
The listed objects currently include most objects in the asteroid belt and moons of the giant planets in this size range, but many newly discovered objects in the outer Solar System are missing, such as those included in the following reference. [58] Asteroid spectral types are mostly Tholen, but some might be SMASS.
COROT-7b, discovered right after HD 7924 b, is the first super-Earth discovered that orbits a main sequence star that is G class or larger. [24] The discovery of Gliese 581e with a minimum mass of 1.9 Earth masses was announced on 21 April 2009. It was at the time the smallest extrasolar planet discovered around a normal star and the closest in ...
[105] [106] It is the largest recorded object to have encountered the Earth since the 1908 Tunguska event. [107] [108] The meteor is estimated to have an initial diameter of 17–20 metres and a mass of roughly 10,000 tonnes. On 16 October 2013, a team from Ural Federal University led by Victor Grokhovsky recovered a large fragment of the ...
The gravitational potential energy is the potential energy an object has because it is within a gravitational field. The magnitude & direction of gravitational force experienced by a point mass m {\displaystyle m} , due to the presence of another point mass M {\displaystyle M} at a distance r {\displaystyle r} , is given by Newton's law of ...
