( http :// www. ciclops. org / view_event / 178 / Lightning_Flashing_in_Daylight ) Though three visiting spacecrafts – Pioneer 11 in 1979, Voyager 1 in 1980 and Voyager 2 in 1981, failed to provide any convincing evidence from optical observations, in July of 2012 the Cassini spacecraft detected visible lightning flashes, and electromagnetic sensors aboard the spacecraft detected signatures that are characteristic of lightning.

Though the upper limits of her powers were never clearly defined, it is assumed that Phantazia could use her power to disrupt anything of an electromagnetic nature.

Though not fully elaborated, Triumph's powers were said to be control over the electromagnetic spectrum.

Though this effect was not confirmed, it is interesting to note that a connection between light and magnetism was suspected so many years before the announcement in 1867 by James Clerk Maxwell of the electromagnetic theory of light.

Though more than 99 % of the dry atmosphere is IR transparent ( because the main constituents — N < sub > 2 </ sub >, O < sub > 2 </ sub >, and Ar — are not able to directly absorb or emit infrared radiation ), intermolecular collisions cause the energy absorbed and emitted by the greenhouse gases to be shared with the other, non-IR-active, gases.

Though the finches were less important for Darwin, more recent research has shown the birds now known as Darwin's finches to be a classic case of adaptive evolutionary radiation.

Though still in limited use, the QFE has been superseded by much more accurate radiation measurement devices.

Though these were the same erasable chips, there was no window for UV radiation to erase them.

Though contributing to the economy of the area by attracting tourists, the practice is controversial because of the " well-documented ill effects of high-dose radiation on the body.

Though some radiation escapes into space, it is absorbed and subsequently re-emitted by atmospheric gases.

Though bowerbirds have traditionally been regarded as closely related to the birds of paradise, recent molecular studies suggest that while both families are part of the great corvid radiation that took place in or near Australia-New Guinea, the bowerbirds are more distant from the birds of paradise than was once thought.

Though the ICZN does not regulate taxa higher than superfamilies, two approaches to deal with the problem are possible: either the Asilomorpha are abandoned, and the Asiloidea are treated as a member of the basal ( i. e. non-Cyclorrhapha ) radiation of Brachycera.

Though the effect is often mistaken for Cherenkov radiation, the two are distinct phenomena, as explained in the article.

Though this very general picture of pulsars is mostly accepted, Werner Becker of the Max Planck Institute for Extraterrestrial Physics said in 2006, " The theory of how pulsars emit their radiation is still in its infancy, even after nearly forty years of work.

Though not strictly a spectroscopic technique, the ultrashort width of the THz radiation pulses allows for measurements ( e. g., thickness, density, defect location ) on difficult to probe materials ( e. g., foam ).

Though the integrated thermal radiation of stars is not usually appreciably polarized at source, scattering by interstellar dust can impose polarization on starlight over long distances.
