Today’s Astronomical Events – July 26th, 2015

The waxing gibbous Moon passes Saturn and approaches Antares in the evening sky tonight. Observers in Australia will get the best view as the Moon is closest to Saturn and the pair will be overhead at about 8pm. For those in the United Kingdom, the Moon appears about midway between the planet and Antares and can be seen fairly low in the SSW at around 11pm. North American observers will see a similar view but the trio should be higher and more easily seen toward the south.
