28 February: New Moon at 00:46 UT (now). Start of lunation 1264. The next few days are a great time for evening stargazing. Download The Evening Sky Map (PDF) from skymaps.com/tesm/ and enjoy exploring the Universe using just your eyes, binoculars or a telescope! 🔭 #astronomy #stargazing

🌟 The March 2025 edition of The Evening Sky Map is ready for download at skymaps.com/tesm/. It includes a Sky Calendar and user-friendly star maps for the northern and southern hemispheres, as well as equatorial regions. Please share and enjoy exploring the Universe! 🔭 🧪 #astronomy #stargazing

🌟 The amazing "Running Chicken Nebula" (aka IC 2944 in Centaurus) lies 6,500 light years away in our galaxy -- The Milky Way. The nebula contains dark Bok globules which are often sites of active star formation. 🔭 #astrophotography #astronomy #space Equipment details: http://skymaps.com/ir0/

An unprocessed 30x120s live stack image of the curiously named "Running Chicken Nebula" (IC 2944) taken last night from a Bortle 7 inner city location with an Optolong L-eXtreme filter. The processed image will be posted in the near future. 🔭 🐓 #astrophotography Gear details: skymaps.com/ir0/

One of the best ways to learn the night sky is to use The Evening Sky Map -- a 2-page PDF available each month as a free download at: skymaps.com/tesm/ #stargazing #astronomy #space

On 21 February, the Moon will be positioned near Antares in the morning sky. Closest approach occurs at 7h UT with a lunar occultation visible from some countries including Argentina, Chile, Uruguay & Falkland Islands.🔭 #stargazing More info:

Last Quarter Moon occurs on February 20th at 17:33 UT (now), marking the onset of dark moonless evening skies. This is a great time to enjoy stargazing for the next week or so. Head over to skymaps.com/tesm/ to download The Evening Sky Map and treat yourself to a night under the stars! 🔭 #stargazing

Further to the previous post, this is a close-up image of NGC 2438, the planetary nebula near the star cluster M46. The faint central star (mag. 17.7) is a white dwarf that began ejecting its now nebulous material about 8,500 years ago. 🔭🧪 #astronomy Scope details: skymaps.com/ir2/

Messier 46 (M46) is an open cluster of stars situated near Sirius, the brightest star in the night sky. Like many star clusters, M46 is a delightful sight in a pair of binoculars. Use The Evening Sky Map (PDF) at skymaps.com/tesm/ to find M46 and other star clusters in the night sky. 🔭 #stargazing

The Moon will reach apogee (farthest from Earth) at 1h UT (now) on 18 February. At this time the Moon's distance from Earth will be 404,882 km or 251,582 miles and span an angular size of 29.5 arc-minutes.🔭 #stargazing

🌟 In the next few hours the Moon will pass in front of Spica, the brightest star in the constellation Virgo. The event starts at 10h UT on 17 February. However, you will need to be in the South Pacific (preferably on a cruise ship) to actually see the occultation.🛳️ 🔭 #stargazing #astronomy

🌟 The planet Venus is at its brightest (mag. –4.63) at 9h UT on 16 February 2025. The brilliant "evening star" has been visible in the western sky for several months. But on this evening Venus will be at its brightest, so look out for it after sunset, no matter where you are on Earth.🔭 #astronomy

🌟🌎 In the next few hours, Venus, the brightest planet in the evening sky, will show its largest illuminated area as seen from Earth. This will happen at 22h UT on 14 February as Venus nears Earth in its orbit around the Sun. 🔭 #stargazing #valentinesday

🌟 NGC 3324 is a star-forming region in the southern constellation Carina. The nebula is also known as the Gabriela Mistral Nebula due to its resemblance to the Chilean poet and Nobel Prize winner. Can you see the profile of a human face? 🔭 #astrophotography #astronomy

13 February: Moon near Regulus at 3h UT (midnight sky). Regulus is the brightest star in the constellation Leo (the Lion) and is located close to the ecliptic making for regular encounters with the Moon. #stargazing #Moon

February 12: The moon reaches its full phase at 13:53 UT (now). 🔭 #stargazing February Sky Calendar: skymaps.com/skycalendar/

On the evenings of 10 & 11 February, the Moon will be positioned close to the Beehive Cluster (M44) located in the constellation Cancer. Closest approach will occur at 8h UT on 11 February. Use binoculars for a better view.🔭 #stargazing

What is the most breathtaking celestial spectacle you've ever witnessed? For me -- being in an open field with The Milky Way arching across the sky with its dense core above. The sky was exceptionally dark and clear which created an unforgettable immersive experience. Credit: Gerard O'Born, ASSA

🌟 Mars reaches its maximum northern declination of 26.2° at 16h UT on 10 February. Those in the northern hemisphere will notice Mars high in the evening sky. Meanwhile, observers in the southern hemisphere can also spot Mars in the evening sky, albeit much closer to the horizon. 🔭 #stargazing

🌟 In the next few hours the Moon will pass near Castor and Pollux -- the twins of Greek mythology and the brightest stars in the constellation Gemini. Closest approach occurs at 0h UT and 6h UT on 10 February, respectively. #stargazing Sky Myths: skymaps.com/myths/

In 5 hours, at 18h UT on 9 February, the Moon will pass close to the red planet Mars (mag. −0.8). The event will be visible worldwide in the evening sky. However, from parts of Russia, China, Canada & Greenland the Moon will actually pass in front of Mars.🔭 Details:

At 12h UT on 9 February (now), the innermost planet Mercury reaches its superior conjunction with the Sun. This event marks the start of the planet's move into the evening sky. 🔭 🧪 #astronomy Sky Calendar for February 2025: skymaps.com/skycalendar/

🌟 On the evenings of February 7th & 8th the Moon will be close to the M35 star cluster located next to the feet of the Gemini twins. Closest approach will be at 16h UT on the 8th. Look up using a pair of binoculars for the best view. 🔭 #stargazing The Evening Sky Map: skymaps.com/tesm/

🌟 On the evenings of 6 & 7 February, the Moon will appear near Jupiter -- the largest planet in the Solar System. The gas giant is currently positioned between brilliant Venus (west) and the red planet Mars (east). Closest approach is at 2h UT. Just look up and enjoy the sight! 🔭 #stargazing

🌟 On the evening of February 6, the Moon will appear close to the Pleiades star cluster (aka The Seven Sisters & M45). Closest approach will be around 7h UT. Simply look up to enjoy the night sky scene. 🔭 🧪

5 Feb: First Quarter Moon at 8:03 UT (about an hour ago). 🌓 The evenings around First Quarter Moon are the best time to view craters and other lunar features. A high contrast long focal length Maksutov telescope provides outstanding views of the #Moon & planets. 🔭 This 👉 skymaps.com/mak180/

🌟 The Great Orion Nebula (M42) and the nearby Running Man nebula (NGC 1977). M42 is easily visible in binoculars but appears best in a telescope. Photographs reveal more detail and colour which the eye cannot see. 🔭 🧪

🌟 This close-up image of the "headless" Comet C/2024 G3 (ATLAS) was taken on 31 Jan'25. The bright streak is a synchrone -- a region of dust released when the comet's nucleus fragmented on 19 Jan. The comet was just visible to the eye from the dark sky site.🔭 🧪 19x10s Rig: skymaps.com/ir2/

On February 1st the Moon will appear close to Venus (mag. –4.6). The event will be visible in the evening sky worldwide, with closest approach at 21:00 UT. No telescope is required. Just look up and enjoy the view. #stargazing

🌟 Sixty nine million years ago in a galaxy far, far away a star exploded. Now known as SN 2025mb the light from the Type Ia supernova eventually reached Earth in mid-January 2025 where it was first detected by the ATLAS global telescope network on 15 January.🔭 🧪 #astronomy #supernova #space

A journey to a dark sky site near Adelaide turned out to be a wonderful night of stargazing and astro-imaging. Photos of several supernovae in distant galaxies were taken, as well as Comet C/2024 G3. A 14-inch Dobsonian telescope offered stunning views of many objects in The Southern Milky Way. 🔭
