Saturn reaches opposition (opposite the Sun) on 21 Sept at 6h UT. The planet is at its closest and brightest, and shines at magnitude 0.6. Use The Evening Sky Map (skymaps.com/tesm/) to find the ringed planet, and a telescope to see its rings and moons. 🔭 #stargazing

In 6 hours, a Partial Solar Eclipse will begin in the South Pacific, New Zealand and Antarctica. Greatest eclipse will occur at 19:42 UT on 21 Sept. 🔭 More details including eye safety information and a Live Stream at: timeanddate.com/eclipse/solar/…

21 Sept: New Moon at 19:53 UT (now). Start of lunation 1271. 🌟 The next few days are a great time for evening stargazing. Download The Evening Sky Map (PDF) at skymaps.com/tesm/ and enjoy exploring the Universe with your eyes, binoculars or a telescope! 🔭 #stargazing

An image of Messier 7, Ptolemy's Cluster, taken a few minutes ago from a Bortle 7 light polluted site. The large cluster lies 980 light years away and contains about 80 stars, seen here against a background of much fainter Milky Way stars. 🔭 Imaging rig: skymaps.com/ir1/

🌙 Over the next few hours, the crescent Moon will pass near the red-planet Mars in Virgo. Closest approach occurs at 12h UT on Sept. 24th. The event will be visible across the globe as night falls. Simply look to the west! #stargazing #Mars More events: skymaps.com/skycalendar/

The Moon will reach apogee (farthest from Earth) at 10h UT (now) on 26 September. At this time the Moon's distance from Earth will be 405,548 km or 251,996 miles and span an angular size of 29.5 arc-minutes.🔭 #stargazing

🌙 In a few hours, Antares the brightest star in Scorpius will be occulted by the Moon. The event starts around 16h UT on 27 September and is visible from Antarctica and north-western French Southern Territories. A close conjunction will be visible elsewhere. 🔭 #stargazing

🌓 29 September: First Quarter Moon at 23:54 UT (now). The days around First Quarter Moon are a great time to view craters and many other lunar features. A telescope will provide spectacular views. 🔭 #stargazing #moon #space Sky Calendar: skymaps.com/skycalendar/

The October issue of The Evening Sky Map (skymaps.com/tesm/) includes the daily path of comets C/2025 R2 (ATLAS) and C/2025 A6 (Lemmon) on the northern hemisphere all-sky map, making the comets easier to find by using the background stars. 🔭 #stargazing #comet

Dwarf planet 1 Ceres reaches opposition at 4h UT (now) on 2 October 2025. Ceres is currently located in the constellation Cetus (The Whale) and shines at magnitude 7.6. Binoculars or a low-power telescope will reveal its location. Good luck! 🔭 #stargazing

Saturday October 4th is International Observe the Moon Night, a global celebration of our nearest celestial neighbour. Here's a photo from last night where I shared spectacular telescopic views of the Moon with many visitors throughout the evening.🔭 More: moon.nasa.gov/observe/
