Mercury		visible for a few days in mid-June (in Gemini) just after sunset.
Venus		in Gemini, an "evening star" in June; vanishes in the sunset by late July.
Mars		in Pisces, in the pre-dawn sky in the east.
Jupiter		in Virgo, high overhead in June; by August is in the far western sky. In a telescope, look for the colorful bands of its atmosphere and the four "Galilean" moons, extending from the planet like a string of pearls.
Saturn		in Gemini, far west in June; vanishes in the sunset by mid-July.
Distant Planets		Uranus (in Aquarius) & Neptune (in Capricorn) become available in August. Pluto is in Ophiuchus.

• Lagoon Nebula (M8) in Sagittarius - a diffuse nebula, where stars are forming
• Omega (Swan) Nebula (M17) - a diffuse nebula in Sagittarius
