What is the orbital period of Venus? What are the appropriate units for the sun's luminosity? What is a space orbital in chemistry? Based on Kepler's third law, what is the orbital period of Saturn? What is the orbital period of Uranus?
An illustration of Saturn near the moon. (Image credit: Chris Vaughan/Starry Night) In the southwestern sky after sunset on Saturday, Jan. 4, the yellowish dot of Saturn will appear several finger widths below (or celestial WSW of) the waxing crescent moon — close enough to share the view...

The moment you observe the polar ice caps of Mars, the storms of Jupiter or the rings of Saturn, you will instantly be inspired to see more. All you need is some knowledge of the equipment and telescopes needed to both observe and locate them. The brighter planets can be observed with ...
I was never a big fan of double stars till I bought my first refractor, a Stellarvue 105mmT with a feather-touch focuser, and a TV 3-6 zoom. Its my favorite thing to observe from my light polluted back yard (18.3 MPSAS) after Jupiter and Saturn. ...
This is the view through a telescope during the extremely close conjunction of Jupiter and Venus on August 27. Credit: Stellarium Saturn, Mars and Antares are shown on Sunday night August 21 two nights before their lineup. Mars is still the brightest of the bunch at magnitude –0.5. It ...
And of course, binos have the trick of using both eyes that will provide an bit extra lift in effective aperture over a single scope of the same aperture. While I always pack my binos when I go to a dark site, my personal preference for wide field viewing is a fast scope. And I ha...
What is clear is that, as Earth begins to catch up on Mars from behind, the Red Planet s apparent motion in our night sky begins to slow. It slows so much that, a month or so before the exact perigee (Sun-Mars opposition), the apparent motion of Mars in the heavens comes to a ...
41. After the Moon, what is the brightest natural object in the night sky, reaching an apparent magnitude of −4.6, bright enough to cast shadows? 42. According to the standard model of Big Bang cosmology, approximately how old is the Universe? 43. What word, which derives from a ...
"Much later, when I discussed the problem with Einstein, he remarked that the introduction of the cosmological term was the biggest blunder he ever made in his life. But this “blunder,” rejected by Einstein, is still sometimes used by cosmologists even
