Seeing Stars with James Wooten: The Equinox Approaches

This star map shows the Houston sky at 10 pm CDT on September 1, 9 pm CDT on September 15, and dusk on September 30.  To use the map, put the direction you are facing at the bottom.  The Summer Triangle is high overhead.  This consists of the brightest stars in Cygnus, Lyra, and Aquila.  Scorpius, the Scorpion, is in the south, with the ‘teapot’ of Sagittarius to his left.  From the Big Dipper’s handle, ‘arc to Arcturus’ in the west.  Mars pulls away from Saturn in the southwest.  The Great Square of Pegasus is in the east, heralding the coming autumn.

This month, Mars remains in the southwest at dusk this month as it pulls away from Saturn. Mars continues to fade a little each night as Earth continues to leave it farther behind. Mars is near Antares in Scorpius by the end of the month.

Saturn is now lower in the southwest at dusk. It drops into the Sun’s glare late next month.

Venus is now getting harder to see, as it will pass behind the Sun late next month. You can still look for it very low in the east in dawn twilight.

Jupiter is now higher in the east at dawn; it is the brightest thing there until Venus rises. 

The Big Dipper is left of the North Star, with its handle pointing up. From that handle, you can ‘arc to Arcturus’ in the west at dusk. 

Antares, brightest star of Scorpius, the Scorpion, is in the southwest, with the ‘teapot’ of Sagittarius due south. The Summer Triangle is high overhead. The stars of summer are here.  Look for the Great Square of Pegasus rising in the east, indicating that fall is approaching.

Moon Phases in September 2014:
1st Quarter:
September 2, 6:11 am
Full: September 8, 8:38 pm
Last Quarter: September 15, 9:05 pm
New: September 24, 1:12 am

At 9:29 pm on Monday, September 22, the Sun is directly overhead at the equator; everyone in the world has the same amount of daylight. This, then, is the autumn equinox.  For us the days, which have been getting shorter since June 20, actually become shorter than the nights after this equinox. In the Southern Hemisphere, day becomes longer than night and spring begins.

Seeing Stars with James Wooten: The Perseids are back August 12!

Star Chart August 2014

This star map shows the Houston sky at 10 pm CDT on August 1, 9 pm CDT on August 15, and dusk on August 31. To use the map, put the direction you are facing at the bottom. The Summer Triangle is high overhead. This consists of the brightest stars in Cygnus, Lyra, and Aquila. Scorpius, the Scorpion, is in the south, with the ‘teapot’ of Sagittarius to his left. From the Big Dipper’s handle, ‘arc to Arcturus’ and ‘speed on to Spica’ in the southwest. Watch Mars close in on Saturn this month. The Great Square of Pegasus rises in the east, heralding the coming autumn.

This month, Mars is in the southwest at dusk this month. Mars continues to fade a little each night as Earth continues to leave it farther behind. Still, Mars rivals the brightest stars we see at night.

Saturn is also in the south southwest at dusk. Mars passes 3.4 degrees south of Saturn on August 25. 

Venus remains in the morning sky, although it now begins to approach the Sun more and more. Look east at dawn for the brightest point of light there; only the Sun and Moon outshine Venus. Venus remains a morning star for almost all of 2014.

Jupiter emerges from behind the Sun into the morning sky by late August. Venus is about 1/5 of one degree from Jupiter at dawn on August 18th. (Both are low in the east at dawn). 

The Big Dipper is left of the North Star, with its handle pointing up. From that handle, you can ‘arc to Arcturus’ and then ‘speed on to Spica’; those stars are in the west at dusk.  Leo, the Lion, is setting in the west at dusk.

Antares, brightest star of Scorpius, the Scorpion, is in the southeast, with the ‘teapot’ of Sagittarius behind it. The Summer Triangle is high in the east. The stars of summer are here. By late evening you can look for the Great Square of Pegasus rising in the east, indicating that fall is approaching.

Coming to an observatory near you, August 12: The annual Perseid meteor shower peaks next week, late Tuesday/early Wednesday (August 12-13).  As usual, we see more meteors towards dawn because that’s when we rotate into the meteor stream. 

The George Observatory is open 7:00 p.m. August 12 until 2:00 a.m. August 12-13 for the shower.

Seeing Stars with James Wooten: The Summer Triangle is high in the sky

This star map shows the Houston sky at 10 pm CDT on July 1, 9 pm CDT on July 15, and dusk on July 31.  To use the map, put the direction you are facing at the bottom. The Summer Triangle is high in the east.  This consists of the brightest stars in Cygnus, Lyra, and Aquila.  Scorpius, the Scorpion, is in the south, with the ‘teapot’ of Sagittarius to his left.  Leo, the Lion, sets in the west.  From the Big Dipper’s handle, ‘arc to Arcturus’ and ‘speed on to Spica’ in the southwest.  Watch Mars close in on Saturn this month.

Last Quarter: July 18, 9:09 p.m.
New: July 26, 5:42 p.m.

At about 7 p.m. on Thursday, July 3, Earth is as far from the Sun as it will get this year. This is aphelion, when Earth is 94.56 million miles from the Sun, as opposed to the average distance of 93 million miles. On January 4, Earth was at 91.44 million miles from the Sun; that was perihelion (closest approach to the Sun). It turns out that this variation in the Earth-Sun distance is too small to cause much seasonal change. The tilt of Earth’s axis dominates as it orbits the Sun. That’s why we swelter when farther from the Sun and shiver when we’re closer.

Seeing Stars with James Wooten: Break out the sunscreen, ’cause here comes the Summer Solstice

This star map shows the Houston sky at 10 pm CDT on June 1, 9 pm CDT on June 15, and dusk on June 30.  To use the map, put the direction you are facing at the bottom.  Jupiter sets in the west in Gemini, the Twins. The Big Dipper is as high as it gets in the north. Leo, the Lion, is high in the west at dusk. From the Big Dipper’s handle, arc to Arcturus and then speed on to Spica in the south.  Saturn left of Spica in Libra.  Cygnus, Lyra, and Aquila form the Summer Triangle in the east, as Scorpius and Sagittarius rise in the southeast.  Summer has arrived.

This month, Jupiter remains in the evening sky for one more month. Look for it low in the west at dusk, outshining all the stars we ever see at night. 

Mars is in the southwest at dusk this month. Mars continues to fade a little each night as Earth continues to leave it farther behind. Still, Mars rivals the brightest stars we see at night.

Saturn was up all night long last month. Now, it remains well-placed for evening observing. Look low in the southeast at dusk.

Venus remains in the morning sky. Look east at dawn for the brightest point of light there; only the Sun and Moon outshine Venus. Venus remains a morning star for almost all of 2014.

The Big Dipper is above the North Star, with its handle pointing up. From that handle, you can ‘arc to Arcturus’ and then ‘speed on to Spica’; those stars are in the south at dusk.  Leo, the Lion, is high in the west at dusk.

Summer Solstice 2014

At 5:51 a.m. on Saturday, June 21, the Sun is directly overhead at the Tropic of Cancer — the farthest point north where the Sun can be overhead. This therefore marks our summer solstice. On this date, those of us in the northern hemisphere experience the longest day and shortest night of the year, and the midday Sun is as high as possible in the sky. From the Southern Hemisphere, the Sun is as low as possible in the sky on June 21. Folks down there have their shortest day and longest night on their winter solstice. 

Interestingly, we see our earliest sunrise on June 11 and latest sunset on July 1. These are not on the solstice because Earth does not orbit the Sun at constant speed. Rather, Earth speeds up a little near perihelion (January) and slows down a little near aphelion (July).  Thus, for a period extending 10 days before and after the solstice, both sunrise and sunset occur a little later each day. (This close to the solstice, the difference in the height of the Sun each day changes only imperceptibly, allowing this small secondary effect to dominate). As most of us sleep through sunrise and are awake at sunset, days will seem to lengthen all the way through June.

Looking for a cool way to ring in the summer heat? Come out for our Summer Solstice party (part of our Mixers & Elixirs series) on June 21!
