EarthSky Tonight-June 24: Earth passes between sun and Pluto tomorrow

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Pluto – the former planet – comes to opposition on June 25, at 19:00 Universal Time. That is when we on Earth pass more or less between the sun and Pluto, so that this distant world is now opposite the sun in our sky. Of course, in Pluto’s case, it is not exactly opposite since the orbit of Pluto is inclined to the plane of the solar system by 17 degrees. That is a greater inclination than the orbits of Mercury, ... Full Story

EarthSky Tonight-June 23: Waxing gibbous moon passes

EarthSky Tonight-June 23: Waxing gibbous moon passes near Scorpion’s Heart

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight the moon returns to the constellation Scorpius the Scorpion. The brightest star in the immediate vicinity is Antares, whose name means “like Mars,” because of its similar reddish hue. If you remember your Greek mythology, or perhaps episodes of Xena: Warrior Princess, Ares is the god of war, the counterpart to the Roman god Mars. You can perform the color comparison yourself, because the planet Mars lies in the ... Full Story

EarthSky Tonight, June 22: Moon near Crown of the Scorpion on June 22

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight’s moon appears near the upper part of the constellation Scorpius. These three stars are sometimes called the Crown of the Scorpion. Scorpius – which now rises in the south-southeastern sky at early evening, is the constellation of the Scorpion. Individually, the Crown stars are Graffias, Dschubba, and Pi Scorpii. It is rare when star patterns on our sky’s dome have anything to do with real associations ... Full Story

Earthsky Tonight—June 21: Solstice brings northernmost sunrises, sunsets

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Another beautiful photo today from Dan Bush. This one is from his gallery of sunrises and sunsets. We use this photo today in honor of the June solstice, which happens today at 11:28 Universal Time (5:28 Mountain Daylight Time). No world body has designated an official day to start each new season, and yet today is widely recognized as the beginning of summer in the northern hemisphere and beginning of winter on the ...

Earthsky Tonight—June 20: Waxing gibbous moon closer to Spica

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Did you happen to see yesterday’s chart? If so – or if you looked in the actual sky during the evening hours – you might have noticed that last night’s moon was between the planet Saturn and the star Spica. This evening, the moon shines by the star Spica in the constellation Virgo. The moon was to the east of Spica last night. Tonight, if you look, you will find the moon much closer to Spica, the brightest star ... Full Story

Earthsky Tonight—June 19   Waxing moon between Saturn and Spica

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight the moon is in a waxing gibbous phase, meaning it appears more than half lighted but less than full. Tonight, the moon is to the west of the bright star Spica and to the east of the planet Saturn. Yesterday evening, the moon was closer to Saturn. Tomorrow evening, the moon will be closer to Spica. Spica is the brightest star in the constellation Virgo the Maiden. We have also indicated the whereabouts of the ... Full Story

Earthsky Tonight—June 18: A half-moon Joins Saturn

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight, you have another planet-packed evening in store, with a couple of brilliant beacons to point the way. Dazzling Venus is visible in the west as evening falls, and the first-quarter moon shines in the southwest as seen from the northern hemisphere. The brightest “star” near the half-lit moon is Saturn. Thanks to its majestic system of rings, it has become an icon of “outer space” and staple of ... Full Story

Earthsky Tonight—June 17, View Mars tonight via reflected sunlight nearly 28 minutes old

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The crescent moon glides by Mars tonight, making it easy to identify the planet, which has been getting dimmer for the past few months. If you face west about an hour after sunset, Mars is the yellow or orange “star” just to the north of the moon. Saturn, very slightly brighter than Mars, is a bit farther from and above the moon. Mars is known as the “Red Planet,” but most people do not see it with a truly red ... Full Story

Earthsky Tonight—June 16, Waxing Crescent Moon meets the “Little King” of Leo

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org If you have been watching the crescent moon over the past few days, you know that since it passed Venus a couple of nights ago, it slips farther east and is slightly fuller each evening. Tonight it is well placed in the sunset sky in the early evening, appearing to pass near Regulus, the “Little King” or “Heart of the Lion,” in Leo. Face the western sky just after it gets dark and you can easily find the lunar ... Full Story

Earthsky Tonight—June 15: Moon and Venus still close after sunset

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Our chart shows the sky scene for mid-northern latitudes in North America. Depending on where you live worldwide, Venus may appear closer or farther from tonight’s waxing crescent moon, or may even appear below the moon. But no matter. Nighttime’s two brightest heavenly bodies bask away in the west as darkness falls around the world. These two bathing beauties shine by reflecting sunlight. Over time, both worlds ... Full Story
