Two comets will be visible in the night sky in the second half of October: "Swan" and "Lemmon".

Swan was only discovered in September and will approach Earth to within around 30 million kilometres.

It will reach its maximum brightness around October 20th and can even be seen with the naked eye in clear weather. Especially in the evening hours, the comet is clearly visible in the south-western dark sky, offering amateur astronomers an impressive spectacle.

The other comet, Lemmon, is an extremely rare visitor: its last visit was over 1,300 years ago. At the end of October, it will reach its closest point to Earth and will then be particularly bright. Early risers can observe it with binoculars in the early hours of the morning, when it is very high in the sky.

Both celestial bodies consist of ice, dust, and rock – ancient remnants from the early days of our solar system.

The image shows an intense tropical cyclone over the western Pacific, east of Taiwan and the Philippines. The centre of the system is depicted as a light purple and white vortex with a clearly visible eye, surrounded by a ring of red and orange areas indicating the strongest wind speeds. A white arrow marks the typhoon’s predicted track towards the north-west, in the direction of Taiwan. To the west of the storm lie the Philippines, with the cities of Manila and Cebu; to the north of these lies Taiwan, with Taipei. Further west, the Chinese coast, including Hong Kong, and parts of Vietnam can be seen. The coloured wind map shows predominantly green areas outside the storm’s core, indicating significantly weaker winds. White streamlines illustrate the typhoon’s anti-clockwise circulation in the Northern Hemisphere. The highest wind speeds are concentrated around the eye of the cyclone.
