But even this idea proved inadequate to describe the motion of the planets, so the concept of the deferent was added. In this the circular motion of the epicycle was carried round the Earth on a circle that was itself not centred on the Earth, but offset from its centre. All this complexity became redundant, of course, as soon as the view of Copernicus prevailed in which the Earth itself orbited the Sun. It became apparent that the planets displayed retrograde motion when the Earth ‘caught up’ and ‘passed’ the planets in their orbits. February 28 • In the north, the Moon is lining up with Elnath (β Tau), Mars, and Aldebaran. (as seen from Sydney). 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!

The only two names commonly used in Europe were ‘Harvest Moon’ and ‘Hunter’s Moon’. On rare occasions, particularly in religious contexts, the term ‘Lenten Moon’ was used for the Full Moon in March. The other terms, which originated in North America, have been adopted increasingly by the media in recent years. August 27: Saturn arrives at opposition, its brightest of the year at magnitude +0.4. That’s about as bright as a moderately bright star that you might see in the Big Dipper, and appears a pale yellow. Saturn now rises at sunset and remains outall night.There are three different effects that common ideas associate with the equinoxes: One meteorological, and two astronomical. There are strong beliefs in ‘equinoctial gales’, ‘equinoctial tides’ and ‘equinoctial aurorae’. It is often thought that gales are more frequent and strongest at the equinoxes, particularly at the (northern) autumnal equinox. In fact, there are most gale-force winds around the time of the winter solstice in late December and early January. The concept has probably arisen because after the quiet period of summer, depressions, with their accompanying winds, tend to move south and bring high winds to the British Isles. After Junius, he simply counted the months beginning Quintilis, Sextilis (our July and August). This gave:

Originally, the Romans used a lunar calendar, beginning at the spring equinox in March. To keep the lunar calendar in step with the year, what are called intercalary months were sometimes inserted. August 28: Venus, having just moved from an evening to a morning star at mid-month, has now brightened to a dazzling magnitude -4.5 and is an eye-catching spectacle at 5:30 AM. (Remember, the lower the magnitude, the brighter thestar.) Orion is now beginning to sink into the southwest, and the two brightest stars in the sky, Sirius and Canopus (α Carinae), are readily visible to observers at low northern latitudes and, of course, to those who are south of the equator. (Canopus is close to the zenith for those in the far south.) It’s the best of 2023! Mark your calendars for the best stargazing events for the upcoming year. From planetary pairings to a partial solar eclipse, there’s much to look forward to. Sirius, α Canis Majoris (α Cma), in the southern celestial hemisphere, is the brightest star in the sky at magnitude -1.44.

On January 1, the Moon passes 0.7º north of Uranus (mag. 5.7). On January 3 it occults Mars in Taurus (visible from the Indian Ocean and southern Africa), and the next day is 8.1° north of Aldebaran. On January 7, it is 1.9º south of Pollux in Gemini. On January 10, it passes 4.6º north of Regulus, between it and Algieba. By January 14, a day before Last Quarter it will be 3.8º north of Spica in Virgo. As a waning crescent it will be 2.1º north of Antares on January 18. On January 20, one day before New Moon, it is 6.9º south of Mercury (mag. -0.6) just past inferior conjunction and invisible in the evening sky. On January 23, the thin waxing crescent will be 3.8º south of Saturn (mag. 0.8), and a little later, 3.5º south of Venus, much brighter at mag. -3.9. On January 31 it occults Mars again, this time visible from Central America and the southwestern United States. The most numerous class is that of the stones, and these largely consist of silicaceous material. One striking feature of some bodies is the presence of numerous chondrules. Meteorites with these are known, unsurprisingly, as chondrites. Chondrules are small, spherical bodies of silicate minerals that appear to have been melted and formed when floating in space. Their age is estimated at 4.55 thousand million years and they are believed to be material that never condensed into larger bodies. Chondrites (like the comets) are thus thought to be some of the very oldest objects in the Solar System. March 2 • After sunset, Venus (mag. -3.9) and Jupiter (mag. -2.1) are close together in the western sky (as seen from London). Every year I see this book come up on Netgalley and every year I request this and then go and find myself a physical version, as these impressive but compact books give us another guide to the stars for the year coming that always impresses me. Beyond Crux, and on the other side of the Milky Way, lies the rest of Centaurus. Northeast of Crux is the finest and brightest globular cluster in the sky, Omega (ω) Centauri also known as NGC 5139. It is the largest globular cluster in our Galaxy and is estimated to contain about 10 million stars. Although appearing like a star, its non-stellar nature was discovered by Edmond Halley in 1677.

The initial object (a small asteroid) was estimated to have a diameter of about 20 metres and approached from the direction of the Sun, which is why it was not detected before arrival. Following the airburst, some fragments survived to reach the ground, west of Chelyabinsk. The snow-covered ground made the recovery of these relatively easy. Most, however, found their way into private hands. The largest known fragment was eventually recovered from the frozen Lake Cherbakul after a long recovery process. This proved to have an initial mass of 654 kg. All the recovered meteorites were found to be ordinary stony chondrites (see here).

August 11/12/13: The great Perseid Meteor Shower will have excellent dark sky viewing conditions, since the peak is close to the new Moon (i.e., no moonlight to interfere!). The Perseids deliver a meteor a minute in dark cloudless skies. These shooting stars are best seen after midnight. Learn all about the Perseids. SummerStargazing This in-depth guide first introduces readers to the objects in the sky – from stars, to comets, to globular clusters – and then takes them through the cosmic events to look out for each month in 2023, with sky maps, moon phase charts and info about the planets.

The two stars Dubhe and Merak (α and β Ursae Majoris) are known as the ‘Pointers’, because they indicate the position of Polaris, the Pole Star (α Ursae Minoris), at about a distance of five times their separation. Following this line takes you to the constellation of Ursa Minor, the ‘Little Bear’ or ‘Little Dipper’, where Polaris is at the end of the ‘tail’ or ‘handle’. The 2023 Night Sky Almanac is now available. The 2023 Night Sky Almanac is the ideal resource for both novice and experienced sky watchers in the United States and Canada, with all the advice, information and data that enthusiasts need to understand and enjoy the wonders of the night sky. This month the constellation of Carina is well placed for observers at 20°N or more to the south. Canopus (α Car) is the second brightest star in the sky. Avior (ε Car) and Aspidiske (ι Car) form the False Cross, together with two stars that belong to the constellation of Vela: Alsephina (δ Vel) and Markeb (κ Vel). The small constellation of Volans is almost embedded in Carina.August 24: The First Quarter Moon, the season’s best for observing lunar features telescopically, hovers to the right of the famous red supergiant Antares, the alpha starof Scorpius. February 3 • The Moon forms a nice, almost isosceles, triangle with Pollux and Castor (as seen from Sydney). For observers slightly farther north, say at 50°N, additional constellations become circumpolar. The most important of these are Perseus, not far from Cassiopeia, and most of which is visible and, farther round, the northern portion of Auriga, with bright Capella (α Aurigae). On the other side of the sky is Deneb, the brightest star in Cygnus, although it is often close to the horizon, especially during the early night during the winter months. Vega (α Lyrae) another of the three stars that form the Summer Triangle is even farther south, often brushing the northern horizon, and only truly circumpolar and clearly seen at any time of the year for observers at 60°N. A beautiful guide of what to expect to see within the night sky in 2023. I think it's amazing that it can be used anywhere in the world, it'd be a great present to get for someone who travels a lot, you could certainly take it away with you!
