Lichfield is a city status in the United Kingdom and civil parish in Staffordshire, England. One of seven civil parishes with city status in England, Lichfield is situated 25 km north of Birmingham and 200 km northwest of central London....

 


Here Are the smaller fields that are involved with astronomy.
Physics
A major component of astronomy is physics which is refered to as astrophysics and high-energy astrophysics. A good way to put it is simply this.

The field is so small that only a few foreground stars in the Milky Way lie within it; thus, almost all of the 3,000 objects in the image are galaxies, some of which are among the youngest and most distant known.

Field characteristics
The field is similar to that of a bar magnet, but this similarity is superficial.

The field is unusual not only because the dipole is tilted and offset from the centre of the planet but also because the small-scale components of the field are relatively large.

The field is similar to that of a bar magnet, but this similarity is superficial. The magnetic field of a bar magnet, or any other type of permanent magnet, is created by the coordinated spins of electrons and nuclei within the atoms.

WIDE FIELD SAGITTARIUS
The Milky Way runs from top to bottom in this photo taken in October of 1990. Sagittarius (the Archer), with its prominent Little Milk Dipper, dominates the center of the image.

Actual field of view (deg) = time in seconds / 240 seconds
For example, if the timed crossing of the field of view is 120 seconds, then the actual field of view is 0.5 degrees.

Hubble Deep Field
In a region of sky one-tenth the diameter of the full Moon, Hubble Space Telescope found more than 1,500 galaxies. If the rest of the sky is this densely populated, our universe must contain at least 50 billion galaxies. (STScI) ...

Earth's Magnetic Field
The earth acts like a bar magnet. Study of the magnetic field gives more clues about the earth's core including the recent discovery that part of the core may be rotating more rapidly than the outer part of the earth.

Definition: magnetic field: A description of the strength of the magnetic force exerted by an object. Bar magnets have "di-polar" fields, as the force is exerted from the two ends of the bar.

Penfield didn't give up. He knew that PEMEX had drilled exploratory wells in the region in 1951. One of the wells had bored into a thick layer of igneous rock known as "andesite" about 1.3 kilometers down.

A collection of eight separate, yet interconnected, cameras originally used as the main optical instrument on the Hubble Space Telescope.

Like field biologists who study the populations and life cycles of animal herds, the SOHO researchers analyzed the appearances and disappearances of large numbers of the small magnetic concentrations on the solar surface.

Magnetic field lines loop through the solar atmosphere and interior to form a complicated web of magnetic structures. Many of these structures are visible in the chromosphere and corona, the outermost layers of the Sun's atmosphere.

electric field A field extending outward in all directions from a charged particle, such as a proton or an electron.

Magnetic field lines
These lines are a way to show the structure of a magnetic field. A compass needle will always point along a field line. The lines are close together where the magnetic force is strong, and spread out where it is weak.

MAGNETIC FIELD
A magnetic field is a region near a magnet where other magnets are affected. The Earth's magnetic field is probably caused by its molten iron-nickel core.

Magnetic Field
A condition found in the region around a magnet or an electric current, characterized by the existence of a detectable magnetic force at every point in the region and by the existence of magnetic poles.

Magnetic field: The region of "altered space" that will interact with the magnetic properties of a magnet. It is located mainly between the opposite poles of a magnet or in the energetic space about an electric charge in motion.

Magnetic Field
a field of force that is generated by electric currents. The Sun's average large-scale magnetic field, like that of the Earth, exhibits a north and a south pole linked by lines of magnetic force.

magnetic field -- a representation of the means by which magnetic forces are transmitted from one body to another.
magnetic lines of force -- fictitious lines used to visualize the orientation and strength of a magnetic field.

Petersen's Field Guide to the Stars and Planets comes highly recommended. It is very inexpensive ($13), small and handy to use at the telescope.

In the same field, just to the south, lie three more galaxies: 7173, 7174, and 7176. Lacaille 9352 is a red dwarf 11.68 light years away, with a visual magnitude of 7.44. It has a proper motion of 6.

In a golden field guide, I read that the Sun spends more time in the constellation Ophiuchus than in Scorpius right now, because of the precession of the equinoxes. I believe this is incorrect.

Hubble Deep Field North (HDF-N) is a tiny region of the northern sky near the Big Dipper toward which the Hubble Space Telescope was pointed for ten straight days in 1995.

Geomagnetic Field. The magnetic field observed in and around the Earth. The intensity of the magnetic field at the Earth's surface is approximately 0.32 gauss at the equator and 0.62 gauss at the north pole.

In the above field the milky way has its brightest parts of the entire northern sky. Rich star fields are intersected by dark lanes of dust.
