While I have read several books on the next predicted pole shift, I have not encountered any work with the detailed source material used in this book. The obvious answer is that the Earth flips °, because as the Sun moves from below the galactic plane to above, the ambient magnetic field gradually changes from one polarity, via neutral /5(15).

lying close to the North Galactic Pole. This high latitude region is largely devoid of bright and hot OB stars (that can contami-nate the observed far UV emission signal), and has a relatively low value of interstellar reddening (galactic plane regions.

The NGP lies along a line that passes through the observer and is perpendicular to the galactic equator. At the other end of this line is the south galactic pole with b = degrees. The number density of stars decreases as we look from the galactic centre towards the galactic poles, as we are looking out of the disk of the Milky Way.

The NGP is located in the constellation Coma Berenices. Astronomers are entering an era of μas-level astrometry utilizing the 5-decade-old IAU Galactic coordinate system that was only originally defined to $\\sim$0°.1 accuracy, and where the dynamical centre of the Galaxy (Sgr A*) is located $\\sim$0° from the origin.

We calculate new independent estimates of the North Galactic Pole (NGP) using recent catalogues of Galactic disc Cited by:   The North Galactic Pole lies far from the cluttered disc of the Milky Way, and offers a clean, clear view of the distant Universe beyond our home galaxy. In the sky, it is located somewhere in the northern constellation of Coma Berenices (Berenice's Hair), a region that also contains an especially rich galaxy cluster known as the Coma Cluster.

Abstract. Results from a complete survey of proper motions to B = at the North Galactic Pole are summarized. Evidence from this and other surveys indicates that (1) the thick disk may extend to as much as kpc above the Galactic plane at the solar radius, and (2) the thick disk may contain stars with metallicities as low as [Fe/H] = − or lower.

Interestingly, Blanco 1's northern analogue, Melotte (the Coma Berenices Star Cluster), is found less than 2[degrees] from the north galactic pole. Having one large cluster situated near a galactic pole is curious; two is a very odd coincidence.

The first galactic coordinate system was used by William Herschel in A number of different coordinate systems, each differing by a few degrees, were used untilwhen Lund Observatory assembled a set of conversion tables that defined a standard galactic coordinate system based on a galactic north pole at RA 12 h 40 m, dec +28° (in the B epoch convention) and a 0° longitude.

Even though we are so far North of our Celestial Equator Can we see the South Galactic Pole in Autumn as the Earth orbits along the path of the planets. In short the answer is Yes. Given our latitude of 48 degrees, and the inclination of the plane of the galaxy to our orbital plane, we should see the South Galactic Pole.

The North Galactic Pole lies far from the cluttered disc of the Milky Way, and offers a clean, clear view of the distant Universe beyond our home galaxy. In the sky, it is located somewhere in the northern constellation of Coma Berenices (Berenice’s Hair), a region that also contains an especially rich galaxy cluster known as the Coma Cluster.

Arthur Beer who was a member of the Royal Astronomical Society and the International Astronomical Union. Galactic North: Reynolds excels at shorter lengths Originally posted at Fantasy Literature Having read all the full-length novels in Alastair Reynolds’ REVELATION SPACE series, I knew I’d eventually get to his shorter works set in the same dark and complex universe.

The main novels are Revelation Space, Redemption Ark, Chasm City, Absolution Gap, and The Prefect/5(). For a long time I have been intrigued by the concept of the Hollow Earth. I remember reading Raymond Bernard's book on the subject (The Hollow Earth - ) in the mid 's and felt a strong affinity for the whole idea.

Next, I read a strange book called "Etidorhpa" by John Uri Llyod written in the late 's about a person who traveled from the Outer Surface to the Inner Surface of the.

Even more extraordinarily, it turns out that the declination of the North Galactic Pole was then equal to the latitude of Stone­henge. Consequently, when the Galactic Centre was on the horizon, the Galactic Pole was in the zenith and the Galactic Equator coincided with the horizon (Fig.

Abstract. Star count data in the magnitude range 12 ≤ V ≤ 18 covering 24 square degrees of the North Galactic Pole region have been obtained in the UBV colour bands. The photographic plates were taken with the Kiso Schmidt telescope, were subsequently scanned with the COSMOS machine, and were reduced at the Royal Observatory, Edinburgh.

Galactic North is an outstanding collection of stories from the Revelation Space universe. For the most part, they are entertaining and engaging, and provide several viewpoints on this terrific space opera/cyberpunk universe.

It made me want to read more by Alastair Reynolds. My favorite among these stories is the title novella, "Galactic North Reviews:   the image above may approximate the next position of the “new earth” if the North Pole is near Lake Baikal, as Professor Charles Hapgood suggests it might be in his books.

I believe that cosmic events emanating from the galactic center cause recurring, periodic, and predictable pole shifts on earth. The galactic plane is the plane on which the majority of a disk-shaped galaxy's mass lies. The directions perpendicular to the galactic plane point to the galactic actual usage, the terms galactic plane and galactic poles usually refer specifically to the plane and poles of the Milky Way, in which Planet Earth is located.

Some galaxies are irregular and do not have any well-defined disk. A finding list of stars of spectral type F2 and earlier in a north galactic pole region.

The papers deal with problems of astronomy and the dynamics of stellar systems. The topics covered include the motion of stars against the background of a Friedmannian expanding universe; some difficulties encountered in classical relaxation theory; a critical survey of existing results concerning the stability of a gravitating cylinder; spectrophotometric studies of central stars in.

have discovered something very interesting in the Book of Enoch. In the 18th chapter, he is describing a journey with the angels, where they are flying in an angelic "spaceship" southwards on the earth, and coming to a place where there are pillars of heavenly fire.

To me, this sounds like they were flying over Africa (from the Middle East), and coming to the South Pole, and watching the. The second catalogue was used to display two-dimensional distributions of the interacting planetary nebulae, moreover IAU and other references used the equatorial coordinates of these nebulae to determine the equatorial coordinates of the north galactic pole (NGP).

This animation shows the movement of the north magnetic pole at year intervals from to The red and blue lines indicate “declination,” the difference between magnetic north and true north depending on where one is standing; on the green line, a compass would point to true north.

This is a plot of thegalaxies in the Minnesota Automated Plate Scanner North Galactic Pole (MAPS-NGP) catalog which don't have any known image defects (that is they are not flagged). This plot contains all the galaxies larger than 10 arcseconds in angular diameter over the twelfth of the sky closest to the north galactic pole (the point in the sky straight out of the plane of the.

Galactic latitude. Latitude (symbol b) measures the angle of an object north or south of the galactic equator (or midplane) as viewed from Earth; positive to the north, negative to the south. For example, the north galactic pole has a latitude of +90°. Analogous to terrestrial latitude, galactic latitude is usually measured in degrees.

Quadrants in the galactic coordinate system. In actual astronomical practice, the delineation of the galactic quadrants is based upon the galactic coordinate system, which places the Sun as the pole of the mapping Sun is used instead of the Galactic Center for practical reasons since all astronomical observations (by humans) to date have been based on Earth or within the solar system.

Coma Berenices cover the North Galactic Pole. We see few Galactic star clusters here but many external galaxies. Herschel ( ) and his sister Your book gives estimates of the mass of the Galaxy from 1 to 4 X solar masses.

A more recent determination of the mass of the Galaxy is even larger, ~ X Question: A) [2 Marks) Draw A Picture Of The Disk Of The Milky Way As Seen From Above (i.e., From The North Galactic Pole) By Marking The Positions Of The Centre Of The Milky Way And The Solar System. Mark The Direction Of Increasing Galactic Longitude.

The North Celestial Pole is circling counterclockwise around the North Ecliptic Pole. From Kaler's The Ever-Changing Sky. Presently the Earth's North Pole points to Polaris, years ago it pointed towards Vega.

Other North "pole stars" in year cycle are shown below. The image shows the North Galactic Pole, and it covers some square degrees of the sky.

Interestingly, this area happens to contain a galaxy-rich cluster known as the Coma Cluster, which. Galactic Latitude is measured north from the plane of the Milky Way; the North Galactic Pole is in Coma Bernices, near RA = and Dec = + Galactic Longitude is measured east from the direction towards the center of the Milky Way, which is in Sagittarius, near RA = and Dec =.

The north magnetic pole is restless. Distinct from the geographic North Pole, where all the lines of longitude meet at the top of the world, the magnetic pole is the point that a compass.

The galactic longitude l is measured in degrees (0° to ). The galactic latitude b (0° to +°) represents the angle between the line of sight from the Sun to the star and the galactic plane. The Sun revolves about the Center of the Galaxy in clockwise direction given the Galactic North Pole as a viewpoint.

The period of the sun's. Other articles where Galactic pole is discussed: galactic coordinate: time, the positions of the galactic poles and equator were redefined, with a change of less than 2° in the positions of the poles. The north galactic pole is now considered to be in the constellation Coma Berenices, at +90° galactic latitude, and with equatorial (Earth-based) coordinates of 12 hours.

The north (NGP) and south (SGP) galactic poles are 90 ° from the galactic equator and are ° from the NCP and SCP, respectively.

The galactic longitude (l) is the arc distance eastward along the galactic equator from the direction to the center of the Milky Way galaxy to where an object ’ s secondary to the galactic equator crosses the. Coma Berenices (abbreviation: Com) is a very faint northern constellation considered to be part of Leo by the Greeks but made separate by Gerardus Mercator in It lies between Canes Venatici to the north, Virgo to the south, Leo to the west, and Bootes to the east, and contains the north galactic pole.

The "zero of longitude" of galactic coordinates was also defined in to be at position angle ° from the north celestial pole. Thus the zero longitude point on the galactic equator was at 17 h 42 m s, −28° 55′ ″ (B) or 17 h 45 m s, −from - 90° at South Galactic Pole to +90° at North Galactic Pole.

The zero-point for longitude is the centre of galaxy; again, the position was fixed by the IAU. The north galactic pole lies in Coma Berenices, Books containing the phrase South Galactic Pole.
