Waxing toward full, the Moon passes over Antares and Saturn Friday, June 30 • First-quarter Moon (exact at 8:51 p.m. The 'star' left of the moon is Jupiter. • And this evening, the Moon's dark limb will occult (cover) the bright, tight double star Gamma Virginis (Porrima) for much of the U.S. The event happens in daylight for the West, twilight for the central longitudes of the continent, and later in darkness for the East. Read more in the, page 50. Here are detailed for hundreds of cities and towns.

(The UT date of the event is July 1st.) Plan ahead! Saturday, July 1 • The Moon in the southwest this evening forms a broad triangle with Jupiter and Spica, as shown above.

Sunday, July 2 • By the time it's fully dark, Altair shines well up in the east. Helping to identify it is its little sidekick Tarazed (Gamma Aquilae), a finger-width above it or to its upper left. (They're unrelated; Altair is 17 light-years from us; Tarazed is about 460.) Look left of Altair, by hardly more than a fist width, for the compact little constellation Delphinus, the Dolphin.

Monday, July 3 • Look far lower right of the Moon at nightfall for Spica; to the right of Spica shines bright Jupiter. Look far lower left of the Moon for orange Antares; left of Antares is pale-yellow Saturn.

These star-and-planet pairs form a roughly symmetrical pattern with the Moon this evening. While its background stars climb toward the upper right. • Before and during dawn for the next few mornings, Venus is passing about 7° south (lower right) of the Pleiades. • Earth is at the aphelion of its orbit, its farthest from the Sun for the year (only 3% farther than at perihelion in January).

Polaris, the brightest star in the constellation, is a yellow-white supergiant and the brightest Cepheid variable star in the night sky, ranging from an apparent magnitude of 1.97 to 2.00. Beta Ursae Minoris, also known as Kochab, is an aging star that has swollen and cooled to become an orange giant with an apparent.

Tuesday, July 4 • Waiting for fireworks to start? Point out some sky sights to folks around you. The waxing gibbous Moon is almost due south at dusk.

Look lower left of it for orange Antares, one of the brightest 'red' supergiants in the sky. Left of Antares is Saturn. Meanwhile, much farther to the right of the Moon, Jupiter shines brightly in the southwest. Wednesday, July 5 • The Moon shines above orange Antares this evening. Upper right of Antares, and lower right of the Moon, is the near-vertical row of three stars marking the head of Scorpius. The top star of the row is Beta Scorpii or Graffias, a fine double star for telescopes.

Just 1° below Beta Sco is the fainter, very wide naked-eye pair Omega 1 and Omega 2 Scorpii, oriented diagonally. Binoculars may show their slight color difference. Left of Beta by 1.6° is Nu Scorpii, another fine telescopic double. High power in good seeing reveals that Nu's brighter component is itself a close binary, separation 2 arcseconds. Thursday, July 6 • Catch golden Saturn shining about 3° below the waxing gibbous Moon, as shown above.

Friday, July 7 • The nearly full Moon shines over the Teapot of Sagittarius after dark tonight, as shown above. Look for it carefully for its stars through the moonlight. The Teapot is about the size of your fist at arm's length, with its handle to the left and its spout to the right. Binoculars may help. Saturday, July 8 • The full Moon is up in the southeast as twilight fades.

Look far to its upper left for Altair, and far to its upper right for Saturn. ________________________ Want to become a better astronomer? Learn your way around the constellations!

They're the key to locating everything fainter and deeper to hunt with binoculars or a telescope. This is an outdoor nature hobby. For an easy-to-use constellation guide covering the whole evening sky, use the big monthly map in the center of each issue of, the essential guide to astronomy. The Pocket Sky Atlas plots 30,796 stars to magnitude 7.6 — which may sound like a lot, but it's less than one per square degree on the sky. Also plotted are many hundreds of telescopic galaxies, star clusters, and nebulae. Shown above is the Jumbo Edition for easier reading in the night... Once you get a telescope, to put it to good use you'll need a detailed, large-scale sky atlas (set of charts).

The basic standard is the Pocket Sky Atlas (in either the or ), which shows stars to magnitude 7.6. Next up is the larger and deeper, plotting stars to magnitude 8.5; nearly three times as many. The next up, once you know your way around, is the even larger (stars to magnitude 9.75).

You'll also want a good deep-sky guidebook, such as Sue French's collection (which includes its own charts), by Strong and Sinnott, or the bigger by Kepple and Sanner. Can a computerized telescope replace charts? Not for beginners, I don't think, and not on mounts and tripods that are less than top-quality mechanically (meaning heavy and expensive). And as Terence Dickinson and Alan Dyer say in their, 'A full appreciation of the universe cannot come without developing the skills to find things in the sky and understanding how the sky works. This knowledge comes only by spending time under the stars with star maps in hand.' This Week's Planet Roundup. And is this the best image of Jupiter ever taken from the ground?

The took it the same night (June 11, 2017) — 'months after opposition,' notes Peach (as indicated by the slightly sideways illumination causing the shading on the left). Mercury and Mars are deep down in the glow of sunset. Venus (magnitude –4.2) shines brightly in the east before and during dawn. Jupiter (magnitude –2.0, in Virgo) shines brightly in the southwest during evening. Spica (magnitude +1.0) glitters 10° left of it. In a telescope, Jupiter has shrunk to 37 arcseconds wide. NASA's Juno spacecraft will at a distance of only 9,000 kilometers.

This flyby ought to provide the most detailed imagery of the Red Spot ever. Here's some recent of Jupiter in support of the mission.

Saturn (magnitude +0.1, in southern Ophiuchus) glows pale yellowish in the south-southeast to south during evening. Fiery Antares, less bright, is 14° to Saturn's right or lower right. Delta Scorpii, the third brightest object in the area, catches the eye half that far to the upper right of Antares. Uranus (magnitude 5.9, in Pisces) and Neptune (magnitude 7.9, in Aquarius) are well placed in the east and southeast, respectively, before the beginning of dawn..

It was one of the 48 constellations listed by the 2nd-century, and is one of the 88 constellations recognised today. With an varying between 2.37 and 2.45, the brightest star in Pegasus is the orange supergiant, also known as Enif, which marks the horse's muzzle.

Twelve star systems have been found to have exoplanets. Was the first Sun-like star discovered to have an exoplanet companion. Contents • • • • • • • • • • • • Mythology [ ] The Babylonian constellation IKU (field) had four stars of which three were later part of the Greek constellation Hippos (Pegasus). Pegasus, in Greek mythology, was a winged horse with magical powers. One myth regarding his powers says that his hooves dug out a spring,, which blessed those who drank its water with the ability to write poetry. Pegasus was the one who delivered 's head to, after which he travelled to in order to be the bearer of thunder and lightning for.

Eventually, he became the horse to, who was asked to kill the and succeeded with the help of and Pegasus. Despite this success, after the death of his children, Bellerophon asked Pegasus to take him to. Though Pegasus agreed, he plummeted back to Earth after Zeus either threw a thunderbolt at him or made Pegasus buck him off.

In ancient Persia, Pegasus was depicted by as a complete horse facing east, unlike most other uranographers, who had depicted Pegasus as half of a horse, rising out of the ocean. In al-Sufi's depiction, Pegasus's head is made up of the stars of the lizard. Its right foreleg is represented by β Peg and its left foreleg is represented by η Peg, μ Peg, and λ Peg; its hind legs are marked by 9 Peg. The back is represented by π Peg and μ Cyg, and the belly is represented by ι Peg and κ Peg. In, the modern constellation of Pegasus lies in (北方玄武), where the stars were classified in several separate of stars. Epsilon and Theta Pegasi are joined with to form Wei 危 'rooftop', with Theta forming the roof apex.

In Hindu astronomy, the Great Square of Pegasus contained the 26th and 27th. More specifically, it represented a bedstead that was a resting place for the Moon. For the and peoples in the stars in the Great Square, corresponding to parts of Pegasus and of Andromeda, represented a barbecue, taken up to the sky by the seven hunters of the myth of Siritjo. Characteristics [ ] Covering 1121 square degrees, Pegasus is the seventh-largest of the 88 constellations. Pegasus is bordered by Andromeda to the north and east, to the north, to the northwest,, and to the west, to the south and to the south and east. The three-letter abbreviation for the constellation, as adopted by the IAU in 1922, is 'Peg'. The official constellation boundaries, as set by in 1930, are defined as a polygon of 35 segments.

In the the coordinates of these borders lie between 21 h 12.6 m and 00 h 14.6 m, while the coordinates are between 2.33° and 36.61°. Its position in the Northern Celestial Hemisphere means that the whole constellation is visible to observers north of 53°S.

Pegasus with the foal next to it, as depicted in, a set of constellation cards published in London c.1825. The horses appear upside-down in relation to the constellations around them. Pegasus is dominated by a roughly square asterism, although one of the stars, Delta Pegasi or Sirrah, is now officially considered to be, part of, and is more usually called 'Alpheratz'. Traditionally, the body of the horse consists of a quadrilateral formed by the stars,,, and. The front legs of the winged horse are formed by two crooked lines of stars, one leading from to and the other from to. Another crooked line of stars from via to forms the neck and head; ε is the snout. Features [ ].

He saw as one star, and was uncertain of its brightness, wavering between magnitude 4 and 5. Flamsteed labelled this star 29 Pegasi, but Bode concluded that the stars 27 and 29 Pegasi should be and and that Bayer had seen them as a single star. Flamsteed added lower case letters e through to y, omitting A to D as they had been used on Bayer's chart to designate neighbouring constellations and the equator.

He numbered 89 stars (now with Flamsteed designations), though 6 and 11 turned out to be stars in Aquarius. Within the constellation's borders there are 177 stars of 6.5 or greater., also known as Enif, marks the horse's muzzle. The brightest star in Pegasus, is an orange of K21b that is around 12 times and is around 690 distant from Earth.

It is an irregular variable, its varying between 2.37 and 2.45. Lying near Enif is, an unusual star that brightened to magnitude 6.0 around 1885 before dimming to magnitude 9.

It is composed of a and, estimated to be around 2.5 and 0.6 times the mass of the Sun respectively. With its outburst taking over 150 years, it has been described as the slowest ever recorded. Three stars with Bayer designations that lie within the Great Square are variable stars.

And are pulsating red giants, while, also known as Kerb, is a —a class of short period (six hours at most) pulsating stars that have been used as and as subjects to study. Rotating rapidly with a of 150 km s −1, Kerb is almost 30 times as luminous as the Sun and has a pulsation period of 56.5 minutes. With an outer atmosphere at an of 7,762 K,it a white star with a spectral type of A5IV.,, and mark the horse's neck.

The brightest of these with a magnitude of 3.4 is Zeta, also traditionally known as Homam. Lying seven degrees southwest of Markab, it is a blue-white main sequence star of spectral type B8V located around 209 light-years distant. It is a that varies slightly in luminosity with a period of 22.952 ± 0.804 hours, completing 1.04566 cycles per day.

It has a red dwarf companion that is 192.3 au distant. If (as is likely) the smaller star is in orbit around the larger star, then it would take around 2000 years to complete a revolution. Marks the horse's eye.

Also known as Biham, it is a 3.43-magnitude white main sequence star of spectral type A2V, around 1.8 times as massive, 24 times as luminous, and 2.3 times as wide as the Sun. (Markab), (Scheat), and (Algenib), together with (Alpheratz or Sirrah) form the large known as the Square of Pegasus. The brightest of these, Alpheratz was also known as both Delta Pegasi and Alpha Andromedae before being placed in Andromeda in 1922 with the setting of constellation boundaries.

The second brightest star is Scheat, a of spectral type M2.5II-IIIe located around 196 light-years away from Earth. It has expanded until it is some 95 times as large, and has a total 1,500 times that of the Sun. Beta Pegasi is a that varies from 2.31 to 2.74 over a period of 43.3 days. Markab and Algenib are blue-white stars of spectral types B9III and B2IV located 133 and 391 light-years distant respectively.

Appearing to have moved off the main sequence as their core hydrogen supply is being or has been exhausted, they are enlarging and cooling to eventually become red giant stars. Markab has an apparent magnitude of 2.48, while Algenib is a that varies between magnitudes 2.82 and 2.86 every 3 hours 38 minutes, and also exhibits some slow pulsations every 1.47 days.

And mark the left knee and Pi Pegasi the left hoof, while and mark the right knee and hoof. Also known as Matar, Eta Pegasi is the fifth-brightest star in the constellation. Shining with an apparent magnitude of 2.94, it is a multiple star system composed of a yellow giant of spectral type G2 and a yellow-white main sequence star of spectral type A5V that are 3.2 and 2.0 times as massive as our Sun. The two revolve around each other every 2.24 years. Farther afield is a binary system of two G-type main sequence stars, that would take 170,000 years to orbit the main pair if they are in fact related. Omicron Pegasi has a magnitude of 4.79. Located 300 ± 20 light-years distant from Earth, it is a white subgiant that has begun to cool, expand and brighten as it exhausts its core hydrogen fuel and moves off the main sequence.

Pi 1 and Pi 2 Pegasi appear as an optical double to the unaided eye as they are separated by 10 arcminutes, and are not a true binary system. Located 289 ± 8 light-years distant, Pi 1 is an ageing yellow giant of spectral type G6III, 1.92 times as massive and around 200 times as luminous as the Sun. Pi 2 is a yellow-white subgiant that is 2.5 times as massive as the Sun and has expanded to 8 times the Sun's radius and brightened to 92 times the Sun's luminosity.

It is surrounded by a circumstellar disk spinning at 145 km a second, and is 263 ± 4 light-years distant from Earth. Is a close binary comprising an and in very close orbit; the latter a candidate for a future as its main star runs out of core hydrogen fuel and expands into a giant and transfers material to the smaller star. Twelve star systems have been found to have. Was the first Sun-like star discovered to have an exoplanet companion; (unofficially named Bellerophon) is a close to its sun, completing an orbit every four days. Spectroscopic analysis of, an in this constellation, has provided the first evidence of atmospheric beyond the solar system, while extrasolar planets orbiting the star also in Pegasus are the first to be directly imaged. Is a hot subdwarf star that has been found to have a planetary companion.

It is a Shapley class IV cluster, which means that it is fairly rich and concentrated towards its center. M15 was discovered in 1746. Is a located in Pegasus, 38 million light-years distant with a redshift of 0.0027. It was discovered by musician-astronomer in 1784 and was later one of the first nebulous objects to be described as 'spiral'. Another of Pegasus's galaxies is, a Type 2.

Located at a distance of 77 million light-years with a redshift of 0.00555, it is an with a at its core. Its characteristic emission lines are produced by gas moving at high speeds around the central black hole. Pegasus is also noted for its more unusual galaxies and exotic objects. Is a that has been by a foreground galaxy.

The lensed quasar resembles a cross because the gravitational force of the foreground galaxy on its light creates four images of the quasar. Is another unique object located in Pegasus. It is a cluster of five galaxies at a distance of 300 million light-years and a redshift of 0.0215.

First discovered by, a Frenchman, in 1877, the Quintet is unique for its interacting galaxies. Two of the galaxies in the middle of the group have clearly begun to, sparking massive bursts of star formation and drawing off long 'tails' of stars. Astronomers have predicted that all five galaxies may eventually merge into one large elliptical galaxy. Meteor showers [ ] The radiate from the area near every year on May 30.
