This image showing the entire disk of Jupiter in infrared light was compiled from a mosaic of nine ... [+] INTERNATIONAL GEMINI OBSERVATORY/NOIRLAB/NSF/AURA, M.H. WONG (UC BERKELEY) AND TEAM ACKNOWLEDGMENTS: MAHDI ZAMANI
Some of the highest resolution images of Jupiter ever obtained from the ground have been shot from the Gemini North telescope on Hawaiis Maunakea volcano.
Remarkably, when combined with those of the Hubble Space Telescope and NASAs Juno mission at Jupiter, the resulting multi-wavelength images reveal lightning strikes.
They also reveal something new about Jupiter's Great Red Spot.

To its east a very short distance (about a degree or two) is Saturn -- much less bright) and then further southeast another about 10 degrees is Mars.

below and to the left of the sky circle is a "Display" box - uncheck the "Deep Sky" to get rid of the clutter that you probably can't see unless you live 50 miles from the nearest streetlamp.
For evening people, Venus is visible after sunset in the western or northwestern sky near the horizon -- a super-bright steady white light (magnitude -4.5 -- unintuitively, the more negative the magnitude, the brighter it is).

(36,261 posts)You're right about the three outer visible planets all being visible at once. In the evening, Venus and Mercury are both visible, and will be at their closest angular separation on 21 or 22 May, depending on your Geographic location.
So catch Mars, Jupiter, and Saturn in the morning and Mercury and Venus in the evening, and you can say you saw all five visible planets on the same day!

(36,261 posts)and had to pull over just to look at the night sky. There were no buildings, no streetlights, and most of the time, no other vehicles nearby. The sky was so dark and clear that I could hardly make out any constellations for all the unfamiliar stars cluttering the view! Unfortunately, my glasses prescription was badly out of date at the time, which didn't help. It was a reminder of how much of Nature we miss out on in our technologically developed society.
