Product Information

This ebook contains the following accessibility features which, if supported by your device, can be accessed via your ereader/accessibility settings: I love the fact this book makes it so easy for people to just read and learn about the night sky and use their map to find the secret patterns in our stars! There is so much knowledge that has gone into this book and so much work too from diagrams to knowledge and information, the important dates on each month on what to look for, I just love that. I also really like how everything is explained and it's so easy to understand, it makes it so much more easy and accessible for beginners to join in!

All objects in the sky appear to be located on an imaginary sphere: the celestial sphere. There are, however, certain fixed points on the celestial sphere, related to points on the Earth. The North Celestial Pole (NCP) and the South Celestial Pole (SCP) are located in line with the projection of the Earth’s rotational axis onto that sphere. In the north, the NCP is very close to Polaris, which has been known as the North Star since antiquity. In a similar way, the celestial equator is the projection onto the sphere of the Earth’s equator. The second co-ordinate, declination, is simply the angular distance, in degrees, north or south of the celestial equator. The Sun has a declination of zero when it appears to cross the celestial equator at the equinoxes. The aim of this book is to help people to find their way around the night sky and to understand what is visible every month, from anywhere in the world. The stars that may be seen depend on where you are on Earth, but even if you travel widely, this book will show you what you can see. The night sky also changes from month to month and these changes, together with some of the significant events that occur during the year are described and illustrated. Meteorites are conventionally divided into ‘falls’, where the body is seen to fall and the location is therefore known (at least approximately) and ‘finds’, where the object is merely found by chance. There are, of course, far more finds than falls, and the numbers in collections are about 65,000 and 1500, respectively.

Mercury is too close to the Sun to be visible this month. It reaches superior conjunction, on the far side of the Sun, on March 17. Venus, in the evening sky, is very bright (mag. -3.9 to -4.0), but too close to the Sun to be readily seen. Mars is initially at magnitude 0.4 in Taurus, but moves into Gemini and fades to mag. 1.0. Jupiter is in Pisces, but is too close to the Sun to be readily visible this month. Saturn is in Aquarius and lies too far into the morning twilight to be seen. Uranus is in Aries at mag. 5.8 and Neptune (mag. 8.0) is in Pisces. That planet comes to superior conjunction on March 15. Cygnus lies along the line of the Milky Way, the disk of our own Galaxy, and provides a wealth of stars and clusters to observe. Just to the left of the line joining Deneb and Sadr, the star at the centre of the outstretched wings, you may, under very clear dark skys, see a region which is darker than the surroundings. This is called the Cygnus Rift and is caused by the obscuration of light from distant stars by a lane of dust in our local spiral arm. the dust comes from elements such as carbon which have been built up in stars and ejected into space in explosions that give rise to objects such as the planetary nebula M57 described above.

Ursa Minor, also with seven main stars, one of which is Polaris, the Pole Star, and the long constellation of Draco that winds around the Pole, are readily visible for anyone in the northern hemisphere, although, of course, Polaris is right on the horizon for anyone at the equator, and thus always lost to sight. Cepheus is near the meridian to the north, with Cassiopeia, to its west beginning to turn and resume its ‘W’ shape. The constellation of Andromeda is now div Running south from Orion is the long constellation of Eridanus (the River), which begins near Rigel in Orion and runs far south to end at Achernar (α Eridani). To the south of Orion is the constellation of Canis Major and several other constellations, including the oddly shaped Carina. The line of Orion’s Belt also points southeast in the general direction of Sirius (α Canis Majoris), the brightest star. Almost due south of Sirius lies Canopus (α Carinae), the second brightest star in the sky. The First Point of Aries is sometimes known as the Cusp of Aries, and the equinox in September as the Cusp of Virgo. This is such a beautiful book, a must in physical form, rather than digital. A great gift for those with even a passing interest in astronomy.The Square of Pegasus is in the south during the evening and forms the body of the winged horse. The square is marked by 4 stars of 2nd and 3rd magnitude, with the top left hand one actually forming part of the constellation Andromeda. The sides of the square are almost 15 degrees across, about the width of a clentched fist, but it contains few stars visibe to the naked eye. If you can see 5 then you know that the sky is both dark and transparent! Three stars drop down to the right of the bottom right hand corner of the square marked by Alpha Pegasi, Markab. A brighter star Epsilon Pegasi is then a little up to the right, at 2nd magnitude the brightest star in this part of the sky. A little further up and to the right is the Globular Cluster M15. It is just too faint to be seen with the naked eye, but binoculars show it clearly as a fuzzy patch of light just to the right of a 6th magnitude star.

There are indeed equinoctial tides, and these tend to be greater in extent than at other times of the year. The effect is well-known and was explained by Isaac Newton in the late-seventeenth century. He explained the effect by stating that the gravitational effect of the Sun is greatest when its declination (here) is at a minimum. It is then acting along a line to the centre of the Earth, and is not offset to north or south. The Sun’s declination is precisely zero when it crosses the celestial equator, and this occurs, twice a year, at the equinoxes. At the equinoxes, the Sun is directly over the Earth’s equator, and thus exerts the greatest influence over the tides. However, the effect is greatest at the equator itself, and is often masked by other effects, such as those caused by atmospheric pressure and winds. The planet (P) orbited on a small circle, carried round a larger circle, centred at the deferent (D), offset from the Earth (E).

The path of minor planet (1) Ceres, around its opposition on March 21. Stars are shown down to magnitude 8.0.February 3 • The Moon forms a nice, almost isosceles, triangle with Pollux and Castor (as seen from Sydney). This month the constellations Lyra and Cygnus are seen almost overhead as darkness falls with their bright stars Vega, in Lyra, and Deneb, in Cygnus, making up the "summer triangle" of bright stars with Altair in the constellation Aquila below.
