The young Kane studied chemistry at his father's factory and published his first paper, " Observations on the existence of chlorine in the native peroxide of manganese ", in 1828.

Observations and measurements of cosmic dust in different regions provide an important insight into the universe's recycling processes ; in the clouds of the diffuse interstellar medium, in molecular clouds, in the circumstellar dust of young stellar objects, and in planetary systems such as our own solar system, where astronomers consider dust as in its most recycled state.

Observations of such a star were made difficult by the limited field of view of Bradley and Molyneux's telescope, and the lack of suitable stars of sufficient brightness.

Observations have shown this star to vary as much as 0. 050 in V magnitude due to starspots and other short-term magnetic activity.

Observations with the James Clerk Maxwell Telescope at a wavelength of 850 μm show an extended flux of radiation out to an angular radius of 35 arcseconds around the star.

Observations of X-ray bursts allow also the determination of the radius of the neutron star.

He directed the preparation of the star maps of the Academy ( 1830 – 1859 ); beginning in 1830, he edited and greatly improved the Astronomisches Jahrbuch ; and he issued four volumes of the Astronomische Beobachtungen auf der Sternwarte zu Berlin ( Observations of the Berlin observatory, 1840 – 1857 ).

* Observations of the most-luminous object in the universe, Arp 220, revealed that the source for its enormous emission of infrared radiation is an outburst of star formation.

Observations of the star S2 in orbit around Sagittarius A * have been used to show the presence of, and produce data about, the Milky Way's central supermassive black hole, and have led to the conclusion that Sagittarius A * is the site of that black hole.

Observations with the Herschel Space Observatory have provided resolved images, which show the disk to be located at a radius of 39 Astronomical Units from the star, or 39 times the distance from the Earth to the Sun.

Observations of a pulsar in a binary neutron star system were used to indirectly confirm the existence of gravitational radiation.

Observations at these wavelengths utilize a coronagraphic spot to block the bright light coming directly from the star.

Observations of an occultation of a bright 5. 5 magnitude star on September 17, 2002, produced seventy-five chords indicating an ellipsoid of 111 × 90 km.

Observations of Iota Horologii in October 2000 appeared to show a dust disc around the star at a distance of 65 AU, similar to the Kuiper belt in our solar system.

Observations with the Hubble Space Telescope detected 32 flare events within a two hour period, with energies of 10 < sup > 27 </ sup > ergs ( 10 < sup > 20 </ sup > joules ) and higher.

In his article Observations on the marital metaphor of YHWH and Israel in its ancient Israelite context: general considerations and particular images in Hosea 1. 2, Ben Zvi describes the role of the Gomer in the marriage metaphor as one of the “ central attributes of the ideological image of a human marriage that was shared by the male authorship and the primary and intended male readership as building blocks for their imagining of the relationship .”

Observations of these disks show that the dust grains inside them grow in size on short ( thousand-year ) time scales, producing 1 centimeter sized particles.

In the United States, the code is given authority ( with some US national differences from the WMO / ICAO model ) under the Federal Meteorological Handbook No. 1 ( FMH-1 ), which itself has paved the way for the US Air Force Manual 15-111 on Surface Weather Observations, being the authoritative document for the US Armed Forces.

Observations are typically undertaken at frequencies of 1, 400 MHz ( equivalent to a wavelength of 21 cm ), 1, 660 MHz ( 18 cm ) and 3, 330 MHz ( 9 cm ).

The NEO Observations Program ( NEOO ) is a result of a 1998 congressional directive to NASA to begin a program to identify 1 kilometer or larger objects to around 90 percent confidence level or better.

Observations distributed according to a mixture of V-dimensional categorical distributions ( e. g., when each observation is a word from a vocabulary of size V ) will have a vector of V probabilities, collectively summing to 1.

A British diarist and Samuel Johnson's friend, Hester Thrale, in her book Observations and reflections made in the course of a journey through France, Italy, and Germany, describes a Polish plait she saw in 1786 in the collection of the Elector of Saxony in Dresden: " the size and weight of it was enormous, its length four yards and a half 4. 1 m ; the person who was killed by its growth was a Polish lady of quality well known in King Augustus's court.
