Earthsky Tonight—- May 25: Mercury at greatest morning elongation on May 26

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Mercury, the solar system’s innermost planet, reaches its greatest morning elongation from the sun tomorrow (Wednesday, May 26). The term greatest elongation specifically applies to inferior planets – the planets that orbit the sun inside of Earth’s orbit: Mercury and Venus. As seen from Earth, Mercury – like a dog on a leash – never strays far from the sun. Mercury only becomes visible in the morning sky when ... Full Story

Earthsky Tonight – April 15: Catch the moon and Mercury after sunset

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Did you see the planet Mercury adorning the evening twilight earlier this month? On our April 8 program, for instance, we showed you Mercury next to the blazing planet Venus at dusk and early evening. Be forewarned. Mercury will be much harder to find this evening than it was at that time. Mercury will be several to many times fainter than it was in late March and early April. Moreover, Mercury will set about 45 minutes ... Full Story

Earthsky Tonight — April 8,  Mercury at greatest evening elongation

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Mercury – the solar system’s innermost planet – goes unnoticed by most people, because it’s so often obscured by the sun’s glare. Even when Mercury is visible – like it is now – it takes a deliberate effort to catch this rather elusive world. This evening, Mercury reaches its greatest angular distance east of the sun. What this means is that Mercury sets a maximum time after sunset today, ... Full Story

Earthsky Tonight — April 3, 2010: Mercury and Venus closest for year

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Have you seen the planet Mercury after sunset yet? If not, what are you waiting for? The first week of April presents your best chance to catch Mercury in all of 2010. Mercury is rather easy to spot right now, because it shines right next to the blazing planet Venus.

Earthsky Tonight – March 31, 2010 Mercury and Venus in same binocular field after sunset

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org If you have never seen the planet Mercury before, now is time to do so. Find the planet Venus in the western twilight after sunset, and you are pretty much assured of spotting Mercury. Venus is easy to find, because it is the third brightest celestial object to bedeck the heavens after the sun and the moon. Mercury, although considerably fainter than dazzling Venus, is still as bright as a first-magnitude star. ... Full Story

Tonight, the waning gibbous moon beams near two bright and beautiful stars

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight, the waning gibbous moon beams near two bright and beautiful stars, Arcturus and Spica. Sparkling above the eastern horizon at early to mid evening, these stars travel westward (along with the moon) throughout the night, and stand high in your southern sky in the wee hours after midnight. As dawn starts to color the sky, these gems light up the western sky. In early spring, these two springtime stars ... Full Story

Earthsky Tonight – January 26, 2010

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org As seen from Earth, the planet Mercury – the solar system’s innermost planet – appears to be closely tethered to the sun. But tomorrow morning, Mercury will swing to the end of its tether – the outermost point of its orbit. Astronomers call this event Mercury’s greatest western elongation. Therefore, Mercury will appear in the early dawn sky before sunrise for the next week or so. However, it’ll still ... Full Story

Earthsky Tonight – Dec 23 2009 Star-hop to Mercury from the Summer Triangle

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The first three stars to pop out into your western sky after sunset are Vega, Altair and Deneb. These brilliant stars make up the huge asterism known as the Summer Triangle. An asterism is a star formation that is not an officially recognized constellation. Don’t mistake the planet Jupiter (outside of our sky chart) for a Summer Triangle star. Jupiter beams in the southwestern sky, to the left of the Summer ... Full Story
