Earthsky Tonight — April 24, Waxing gibbous moon pairs with Saturn

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Tonight, the oval-shaped waxing gibbous moon shines close the ringed planet Saturn. At this time yesterday, a somewhat thinner waxing gibbous moon shone close to Regulus, the brightest star in the constellation Leo the Lion. Why has the moon moved?

Leo’s brightest star – the sparkling blue-white gem Regulus – dots a backward question mark of stars known as The Sickle. If you could see a Lion in this pattern of stars, The Sickle would outline ... Full Story

Tonight, the waning gibbous moon will rise an hour or so after nightfall. However, the constellation Leo the Lion won’t be totally above the horizon until about 2 hours after darkness falls. Like the sun, the stars swing full circle across the sky once a day. Unlike the sun, however, the stars return to the same place in the sky in ... Full Story

Although Regulus rates as a first-magnitude star, it may be hard to spot in the lunar glare tonight. Try binoculars, if you can’t see Regulus with the eye alone. The ... Full Story
