EarthSky Tonight—August 21,  Summer Triangle high overhead on summer evenings

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Our sky chart shows the Summer Triangle asterism as it appears at late evening. As seen from mid-northern latitudes, Vega – the Summer Triangle’s brightest star – shines high overhead around 10:00 p.m. daylight saving time (9:00 p.m. standard time) this evening. Altair resides to the lower left (southeast) of Vega, and Deneb lies to Vega’s left (east). As the stars drift westward during the night, Deneb will swing ... Full Story

Earthsky Tonight—August 8, Look overhead to see the summer Milky Way

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org The moon will be new tomorrow and then in a waxing crescent phase in the west after sunset in the next few days. That means that, over the coming week, the moon will set soon after sunset and be mostly absent from the evening sky. A moonless sky means this is a good time to get out into the country for a look at the summer Milky Way: the edgewise view into our own galaxy. Here is the view if you are standing facing east ...

Earthsky Tonight—July 29, Summer Triangle and the smallest constellations

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org I pointed out the Summer Triangle earlier this month. This famous pattern of stars is now at its best in the night sky. The Summer Triangle consists of three bright stars – Vega, Deneb and Altair – in three separate constellations. If you can find the Summer Triangle, you can use it to locate three of the sky’s smallest constellations: Vulpecula the Fox, Delphinus the Dolphin and Sagitta the Arrow. EarthSky’s ... Full Story

Earthsky Tonight—July 19, Summer Triangle: Altair and Aquila the Eagle

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org In the east after dark, near the horizon, Altair, the brightest star in the constellation Aquila, the Eagle, springs into view. This is the bottom star of the Summer Triangle. The Great Rift of the Summer Milky Way passes through the Summer Triangle, between the stars Vega and Altair. Thought the Great Rift and the Milky Way will be hard to see tonight because of the waxing gibbous moon. In dark skies in late July and the ... Full Story

Earthsky Tonight—July 16, Summer Triangle: Deneb and Cygnus the Swan

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org This evening, the fat waxing crescent moon shines by the planets Saturn and Mars in your southwest or western sky. For a sky chart of the evening planets, we refer you to yesterday’s program. Be sure to notice how the position of tonight’s moon relative to Saturn and Mars has changed since yesterday. Tonight’s chart faces a different section of sky than where the moon and planets reside. We are looking eastward at ... Full Story

Earthsky Tonight—11: Altair, guide star to two small constellations

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Look in the east at nightfall and evening to locate a sparkling blue-white star not far from the horizon. That is Altair, the brightest star in the constellation Aquila the Eagle, and the second brightest star in the Summer Triangle. The Summer Triangle formation is made up of the three bright summer stars, Vega, Deneb and Altair. The Summer Triangle lights up the eastern sky on June evenings. Once you have found Altair, ...

Earthsky Tonight—June 10: Find the Summer Triangle

Earthsky Tonight—June 10: Find the Summer Triangle ascending in the east

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org An asterism is not the same thing as a constellation. Constellations generally come to us from ancient times. Earlier in this century, the boundaries of 88 constellations were officially drawn by the International Astronomical Union. On the other hand, asterisms are whatever you want them to be. They are just patterns on the sky’s dome. You can also make up your own asterisms, in much the same way you can recognize ... Full Story

Earthsky Tonight—June 4: Rastaban and Eltanin belong to constellation Draco

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org One of you asked, "What are constellations?" The answer is that they are just patterns of stars on the sky’s dome. The Greeks and Romans, for example, named them for their gods and goddesses, and for many sorts of animals. In the 20th century, the International Astronomical Union (IAU) formalized the names and boundaries of the constellations. Now every star in the sky belongs to one or another constellation. The ...

Earthsky Tonight—June 3: See Draco the Dragon and a

Courtesy of EarthSky   A Clear Voice for Science www.EarthSky.org If you have a dark sky, you will be able to pick the constellationDraco the Dragon winding around the North Star, Polaris. First, find the Big Dipper high in the north on June evenings. The two outer stars in the Dipper’s bowl point to Polaris, the North Star, which marks the end of the Little Dipper’s handle. The Little Dipper is relatively faint. If you can find both Dippers, then your sky is probably pretty ... Full Story

May 30:  Star Deneb belongs to a cross-like star pattern

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Here is the view toward the northeast in mid-evening in the month of May. It is by looking in this direction that you can get a good look at Deneb: the bright star below and to the left of Vega on the sky’s dome. Deneb is the brightest star in the constellation Cygnus the Swan. If you look at the pattern indicated on today’s chart, you might be able to imagine Deneb as the point marking the tail of a swan flying ... Full Story
