In cases in which the original subject is sufficiently self-luminous, such as in explosions, a fast shutter may be required.
During this period, it's thought that the first luminous sources, such as stars, quasars, and galaxies, appeared in the universe, causing the previously neutral intergalactic medium, made mostly of hydrogen gas, to become ionized.
More often, the poet's voice is manifest in a luminous sentence such as: "The weather was white with the coming rains". Much of the book consists of extended conversations between Forché and the varied people she meets.
Very luminous stars, such as Deneb, Rigel, and Betelgeuse, have absolute magnitudes of −7 to −9, while one of the faintest known stars, the companion to the star with the catalog name BD + 4°4048, has an absolute visual magnitude of +19, which is about a million times fainter than the Sun.
Therefore, we surveyed the words that refer to luminous phenomena, such as vapor, light, and cloud.
The inner regions of accretion flows in luminous sources such as AGN and X-ray binaries are radiation dominated.
Light can generate both luminous accidents, such as those in immaterial lights, physical lights or rays, and dark accidents, whether it be in immaterial lights or in bodies (PI, 77.1 78.9).
Self-luminous paints, such as are used for dial markings for watches and other instruments, owe their behaviour to radioluminescence.
Mariana Figueiro led a team of scientists who found that exposure to the light from self-luminous displays, such as Apple iPads, could be "linked to increased risk for sleep disorders because these devices emit optical radiation at short wavelengths, close to the peak sensitivity of melatonin suppression".
Certainly I had heard snippets of Clara's career told in the traditional way: the glittering career, the superbly histrionic story of her rabid father and haunted husband, the dramatic backdrop of the Dresden uprisings and the growth of pianist-as-cult in the 19th century with luminous show-stoppers such as Liszt and Chopin, warty little Wagner and golden-boy Brahms studding the field.
Discoveries of the transient luminous effects (TLE), such as elves, red sprites, and blue jets, possibly caused by the breakdown at altitudes ∼90 km, revealed the possibility of a much stronger lightning coupling to the ionosphere than previously deemed possible.
