For example, if the map legend says “Looking Southeast,” you should face southeast when using the map. The legend on the map always tells you which direction you should facing, based on midnight viewing. Instead, the map focuses on a particular region of the sky each month where something interesting is happening. Our monthly sky map does not show the entire sky which would be almost impossible.

It’s one of the smallest constellations, and it really does look like a little arrow! Just below Sagitta and similar in size is tiny Delphinus the Dolphin.Įlsewhere on this month’s map, you’ll find other asterisms of note, including the constellation Cepheus, shaped like a house, and Cassiopeia, which looks like a big “W.” And if your horizon is free of trees and houses, you may glimpse the Great Square, the body of Pegasus the Flying Horse.Ĭlick here or on map below to enlarge ( PDF). Sagitta the Arrow is a dim but delightful constellation that sits at the upper left of Altair. Smaller and less prominent, but quite striking, is the exquisite little Parallelogram which hangs just below blazing Vega in Lyra. The largest and most prominent asterism (unofficial star pattern) associated with the Triangle is the Northern Cross, comprised of the brightest stars in Cygnus. Once you’ve spotted the Summer Triangle, you can use it to find other sights. In fact, Deneb is one of the most luminous of all stars-an astounding 200,000 times brighter than our Sun! The light we see from Deneb left the star about the time the Pyramids of Egypt were being built. How can this be? The only way Deneb can both be farther away yet appear equal in brightness is if its actual (or “ intrinsic brightness”) is much greater than the others. But looks can be deceiving! We know that Deneb is more than 100 times farther from us than Vega or Altair, yet it appears nearly as bright. Put another way, their “ apparent brightness” is roughly the same. The three stars of the Summer Triangle appear to be about equal in brightness. A light-year is the distance light travels in one year-a big, BIG number! Apparent Brightness Whereas Vega and Altair are relatively close to us in astronomical terms-25 and 17 light-years respectively-Deneb is much farther away, an estimated 2,600 light-years from Earth.
Alas, Deneb has never starred in a major motion picture, but it has other claims to fame. Number three in the Summer Triangle and 20th brightest star is Deneb, which marks the tail of Cygnus the Swan. We don’t know if Altair is surrounded by any planets, so Altair IV may or may not exist. Altair is the 2nd brightest member of the Summer Triangle and 13th brightest star of all.
In the 1956 film “Forbidden Planet,” the fourth planet in the Altair system (Altair IV) is home to the relics of an ancient alien civilization and to an eccentric Earth scientist and his beautiful daughter (Walter Pidgeon and Anne Francis). Back in the real world, we’ve yet to hear anything from the possible inhabitants of the Vega system, but researchers are listening to Vega and thousands of other stars every day, just in case.Īltair, in Aquila the Eagle, is another Hollywood star.

The 1997 movie version features actress Jodie Foster’s quest for the senders of the Vega message. In Carl Sagan’s novel “Contact,” Vega is the source of the first message ever received from an alien civilization. Vega in the constellation Lyra the Lyre is the brightest of the trio and the 5th brightest of all stars.
The three stars of the Summer Triangle appear similar in brightness. At this time every year, the distinctive three-cornered pattern formed by the bright stars Vega, Altair, and Deneb, is prominent in the southern sky. Year after year, century after century, star gazers have celebrated the return of the Summer Triangle.
