After a cloudy night, the sky cleared as dawn arrived on a late summer morning as seen from Bruneau Dunes State Park in southern Idaho on September 8, 2018. Here you see a very slender waning crescent Moon to the upper left of the star Regulus. Mercury is at the lower middle of this image, just above the clouds. Just minutes earlier, the constellation Orion tried to peak through the early-morning clouds (see below) [Read more…] about Dawn Sky – Crescent Moon, Mercury, Regulus, and OrionShare This:
The last Sunday of northern winter in 2018 brought a clear and dry night for stargazing in the Washington, D.C. area. In this image, taken from The Plains, Virginia, shows a slender crescent Moon just 3% illuminated by the Sun’s light. The Moon is joined by the two inner planets Venus (brighter, at center) and Mercury (upper right). Mercury has just passed its greatest eastern elongation and will now begin quickly moving back toward the Sun. Venus moves in the opposite direction, more languorously, as it slowly gets higher and brighter in the coming weeks.
The planet Mercury will appear to pass across the face of the Sun on Monday, May 9, 2016. This event, known as a transit, will be visible in a small telescope with a proper solar filter from much of North and South America, Africa, and western Europe. It’s a great opportunity to see the mechanics of the solar system in action and to spot the elusive inner planet as it passes across the blazing solar disk [Read more…] about A Guide to the Transit of Mercury on May 9, 2016Share This:
All five bright planets are visible in the sky during this last week of 2015 and into the new year. Here’s a roundup of where to find them and what to look for, along with your best chance to easily spot Comet C/2013 US10 (Catalina) on the first morning of 2016 [Read more…] about Planet Roundup… and Comet Catalina UpdateShare This:
If you’re up for a weekend challenge, grab your binoculars, find a clear view down to the eastern horizon, and head out about 30 minutes before sunrise to spot fingernail-thin crescent Moon right next to the planet Mercury in the pre-dawn sky. A pair of binoculars will help you pull an image of the pair out of the brightening sky. Westward (above) this pair you will also see the planets Mars, Jupiter, and Venus in the constellation Leo. The event favors observers in the northern hemisphere, but it is also visible in the south, although the sky will be slightly brighter when Mercury emerges above the horizon.Share This:
