As a result, a radio telescope will pick up very regular pulses of radiation and the object is thus also known a Pulsar. 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. January 22: Venus will meet Saturn In January 2023, the brightest planet Venus will become easier to spot as it climbs slightly higher in the twilight sky each evening. At the equinoxes, the Sun is directly over the Earth’s equator, and thus exerts the greatest influence over the tides. Chondrules are small, spherical bodies of silicate minerals that appear to have been melted and formed when floating in space.

If your sky is very clear, you can also spot Mercury in the twilight, hugging the horizon near where the sun disappeared, on these evenings. To mark International Year of Astronomy, a team of British astronomers have made the largest lunar image in history and gained a place in the Guinness Book of Records!

An annular eclipse occurs when the moon passes across the interior of the sun’s face forming a blinding ring, the “Ring of Fire. Some, such as the Andromeda Galaxy, M31, and the Orion Nebula, M42, may be seen faintly by the naked eye, but all those given in the list here will benefit from the use of binoculars. At 21:54 on the evening of 28 February 2021, a brilliant fireball (a bolide) was observed over Gloucestershire. Most of the constellation of Hercules is visible, together with the distinctive circlet of Corona Borealis to its east. The answer is suprisingly complicated, and involves the ancient Roman lunar calendar, Roman emperors, including Julius Caesar, the Roman Senate, the priests, and the way in which politicians messed about with the calendar, and how we have avoided even greater confusion.

The position of any object in the sky may be described by its altitude (measured in degrees above the horizon) and its azimuth (measured in degrees from north, 0°, through east, 90°, south, 180°, and west, 270°).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. For observers in the far north, most of Cygnus, with its brightest star, Deneb (α Cygni), is visible in the north, and even Lyra, with Vega (α Lyrae) may be seen at times.

Because of the notion that movements in the planetary realm could only occur in ‘perfect’ circles, the idea was introduced that the planets moved on small circles (epicycles) that were themselves carried round the Earth on circular orbits. The monthly pages include diagrams showing the phase of the Moon (see here) for every day of the month, and also indicate the day in the lunation (or age of the Moon), which begins at New Moon. It shows the barred spiral galaxy M109 that lies at a distance of 83 million light years in the constellation of Ursa Major. Observing conditions at maximum are not very favourable in 2023, because the Moon is near or at Last Quarter (Days 22 and 23 of the lunation). At some time or other, nearly everyone has seen a meteor – a ‘shooting star’ – as it flashed across the sky.Several modern names for months derive from the original Roman ‘calendar of Romulus’, which contained just ten months. If the Earth’s rotational axis is extended, for example, it points to the North and South Celestial Poles, which are thus in line with the North and South Poles on Earth. It may just be glimpsed with binoculars on a very clear dark night and a telescope will show it as a misty blur of light. The use of the epicycle and deferent was developed and propagated by the great astronomer Ptolemy (approximate dates 100 to 170 CE), who found that he had to introduce further terms, which he denoted the ‘eccentric’ and the ‘equant’.

Just as Ursa Major is the key constellation in the northern sky, so is Crux (the Southern Cross) an easily recognized feature of the southern circumpolar sky, although at times it may be brushing the horizon for observers at 30°S – roughly the latitude of Sydney in Australia. About 713 BCE, two more, January (Januarius from Janus, the Roman god of beginnings) and February (Februarius, from Februa, the Roman ritual of purification at the end of the year) were added. As dawn brightens on October 10, November 9 and December 9, look toward the eastern horizon for a dramatic scene. The other terms, which originated in North America, have been adopted increasingly by the media in recent years. Between Achernar and the SCP lies the triangular constellation of Hydrus, next to the constellation of Tucana which contains the Small Magellanic Cloud (SMC).Its name "The Crab Nebula" was given to it by the Third Earl of Rosse who observed it with the 72 inch reflector at Birr Castle in County Offaly in central Ireland. Because of their nature, iron meteorites are most likely to survive passage through the Earth’s atmosphere relatively intact and create impact craters on the surface. This image was taken using the Faulkes Telescope North by Daniel Duggan - for some time a member of the Faulkes telescope team. Twinkling nearby will be much-dimmer Regulus, brightest star in Leo the Lion and considered the Heart of the Lion.
