Dark Sky News

From June 12 to June 30, Mercury will be offering its finest showing of 2025. Look low in the western northwest from 9:00 to 9:15 P.M. Right near 9:00, it will be at its brightest magnitude (mag. -0.8). On June 26, you can see Mercury low to the left of the crescent Moon, before it gets to a more comfortable 8-degree elevation from June 29-30.

Don’t forget to look for the summer triangle: Deneb in Cygnus, Vega in Lyra and Altair in Aquila!

Two nice overhead passes of Tiangong, the Chinese Space Station (CSS):

Jun 1 @9:36PM EST at mag. -2.3 from W to E

Jun 3 @9:11PM EST at mag. -2.2 from W to ESE

The Full Strawberry Moon will occur on June 11 at 07:44 GMT and will be in the constellation Ophiuchus.

All of the following are true during the summer solstice:

1. the north pole is tilted most directly toward the Sun
2. the sun reaches its highest point of the year, and is directly overhead at a latitude of 23.5 deg. (Tropic of Cancer)
3. it is the longest day of  the year and points inside the Artic Circle experience 24h of daylight

The New Moon will occur on June 25 at 10:31 GMT. Finally nights are starting to get longer!!! What can I say, I’m a DSO lover 🙂

Haha made you look 🙂 On June 29th, Mars will be hovering just above the crescent Moon. Of course, if you want to see the occulted version, you’ll need to travel to Peru, Ecuador or Colombia! 

As the anniversary of the Tunguska Event, Asteroid Day is the United Nations-sanctioned day of public awareness around planetary defense and the risks that asteroids pose to Earth.

On the morning of June 30, 1908, a large meteorite roughly 100 meters (330 feet) wide exploded above Tunguska, Siberia, leveling 2,000 square kilometers (770 square miles) of forest.
