    The bike has a power-to-weight ratio of 105.75 hp/tonne. The engine design also includes a balancer shaft to repress the vibrations. [3] The Royal Enfield Meteor 350 has a fuel consumption of around 35 km/l. The Royal Enfield Super Meteor released in 2022 boasts very much the same design, but with a 650cc engine. [4]

    en.wikipedia.org/wiki/List_of_supernova_candidates

    Map showing various supernova candidates, most of which are within one kiloparsec from the Solar System. [1] This is a list of supernova candidates, or stars that are believed to soon become supernovae. Type II supernova progenitors include stars with at least 8~10 solar masses that are in the final stages

    In 1958, a Royal Enfield Super Meteor was used by the Transport Research Laboratory to test the Maxaret anti-lock brake on motorcycles. [2] The Maxaret works by detecting rapid decelerations of the wheel that may cause it to lock and releases and re-applies hydraulic pressure to the brake several times a second, keeping the average braking effort at the maximum that can be used by the road ...

  5. History of supernova observation - Wikipedia

    It was the first supernova to be detected through its neutrino emission and the first to be observed across every band of the electromagnetic spectrum. The relative proximity of this supernova has allowed detailed observation, and it provided the first opportunity for modern theories of supernova formation to be tested against observations. [49 ...

    SN 1054 remnant (Crab Nebula)A supernova is an event in which a star destroys itself in an explosion which can briefly become as luminous as an entire galaxy.This list of supernovae of historical significance includes events that were observed prior to the development of photography, and individual events that have been the subject of a scientific paper that contributed to supernova theory.

  7. Supernova impostor - Wikipedia

    en.wikipedia.org/wiki/Supernova_impostor

    Supernova impostors appear as remarkably faint supernovae of spectral type IIn—which have hydrogen in their spectrum and narrow spectral lines that indicate relatively low gas speeds. These impostors exceed their pre-outburst states by several magnitudes, with typical peak absolute visual magnitudes of −11 to −14, making these outbursts ...

    SN 1572 (Tycho's Star, Tycho's Nova, Tycho's Supernova), or B Cassiopeiae (B Cas), was a supernova of Type Ia in the constellation Cassiopeia, one of eight supernovae visible to the naked eye in historical records. It appeared in early November 1572 and was independently discovered by many individuals.

    After this he put the car up for sale for £1,500, but decided to keep it for a further attempt on hearing that Parry-Thomas was also planning a record attempt with Babs. Blue Bird returned to Pendine in 1925, and on 21 July it raised this record to 150.766 mph (242.628 km/h), [ 6 ] the first time a car had exceeded 150 mph (240 km/h).
