Waning Crescent

Moon Phase

Tonight’s Moon is a Waxing Crescent (17%), 3.92 days old, and sets at 9:47PM.  This means a dark sky for our observations, making it easier to see faint objects.

 

ℹ️ Other Information

 We recommend to bring a jacket as the weather can been tricky. As always feel free to bring a picnic blanket, some snacks and non-alcoholic refreshments.  Please don’t forget to bring your Aeroguard or Bushmans in case of mosquitoes or other annoying insects.

 

🔭 In the Sky Tonight

Note that just because these objects are in the sky at the moment, you may not always see them. Visibility is dependent on weather, moon brightness, atmospheric conditions, and equipment parameters. Check the weather and viewing conditions above, and if in doubt ask a friendly volunteer if you’re able to see an object in the night sky!

 

Feature Object:  NGC 1097 (Barred Spiral Galaxy)

NGC 1097 (also known as Caldwell 67) is a barred spiral galaxy about 45 million light years away in the constellation Fornax. It was discovered by William Herschel on 9 October 1790. It is a severely interacting galaxy with obvious tidal debris and distortions caused by interaction with the companion galaxy NGC 1097A.

It has a supermassive black hole at its center, which is 140 million times the mass of the Sun.  Around the central black hole is a glowing ring of star-forming regions with a network of gas and dust that spirals from the ring to the black hole. An inflow of material toward the central bar of the galaxy causes new stars to be created in the ring. The ring is approximately 5,000 light-years in diameter, the spiral arms of the galaxy extend tens of thousands of light-years beyond the ring.  Like our own galaxy (The Milky Way) NGC 1097 has two satellite galaxies, NGC 1097A and NGC 1097B. Dwarf elliptical galaxy NGC 1097A is the larger of the two. It is a peculiar elliptical galaxy that orbits 42,000 light-years from the center of NGC 1097. Dwarf galaxy NGC 1097B (5 million solar masses), the outermost one, was discovered by its HI emission, and appears to be a typical dwarf irregular. Little else is known about it.
