Seeing Stars with James Wooten: Restored Gueymard offers views of brilliant Jupiter this May

Star Map May 2015Mercury is low in the west-northwest, below and slightly to the right. It remains visible for the first half of May before returning towards the Sun.

Venus is in the west at dusk. Look high over the point of sunset for the brightest thing there. 

Jupiter is now high in the west as soon as night falls. Jupiter outshines all stars we ever see at night, so it will be obvious when you look up at dusk.   

Saturn enters the evening sky this month. It rises May 1 by 9:40 p.m. By May 22, it is up literally all night; it rises at sundown and sets at sunrise. This is because Earth is aligned between the Sun and Saturn on that date. We therefore say that Saturn is at opposition. 

Mars is lost in the glare of the Sun.

A swath of brilliant winter stars sets in the west at dusk. Orion, the Hunter, is still visible in the west as May begins. His two dogs, represented by Sirius and Procyon, are to his left.  Gemini, the Twins, are above Orion. The Big Dipper is above the North Star, with its handle pointing to the right. From that handle, you can ‘arc to Arcturus’ and then ‘speed on to Spica’; those stars are high in the east and in the south, respectively, at dusk. Leo, the Lion, passes almost overhead at dusk.

As Orion and Taurus set, look for Antares, brightest star of Scorpius, the Scorpion, to rise in the southeast. Saturn will be right on the Scorpion’s head, above Antares. At the same time, Vega, brightest star of the Summer Triangle, appears low in the northeast. These stars remind us that summer is on the way.Phases10-9x-3w

In case you missed the news, the main telescope at George Observatory is once again fully operational. Thanks in large part to public support, we were able to get our mirror cleaned and then reinstalled. The newly refurbished mirror was opened to the public last weekend. Come join us on clear Saturday nights at the George!

On most clear Saturday nights at the George Observatory, you can hear me do live star tours on the observation deck with a green laser pointer.  If you’re there, listen for my announcement. I generally do one such tour on short May evenings.

Clear skies!

 

Einstein Scavenger Hunt: Guess That Hall!

Einstein at HMNS

 

Our good friend Einstein came to visit the museum and went through many of our exhibit halls. Can you name the halls he’s pictured in? (Click the pictures for answers!)

Seeing Stars with James Wooten: Two eclipses for the price of one!

Star Chart - October 2014

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 in the west. This consists of the brightest stars in Cygnus, Lyra, and Aquila. The ‘teapot’ of Sagittarius sets in the southwest, with Mars to its right. Pegasus, the Flying Horse, is high in the east. To the south and east, we see a vast dim area of stars known as the Celestial Sea, where only Fomalhaut stands out.

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

Saturn drops into the Sun’s glare by Halloween. See how long you can keep track of it as it appears lower and lower to the southwest horizon each night this month.

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

Venus is passing behind the Sun and thus out of sight this month. Superior conjunction (Venus in line with the Sun, on the far side of the Sun) is on October 25.

In October the Big Dipper is to the lower left of the North Star at dusk, and soon sets. As a result, it may be hard to see if you have trees or buildings north of you. As the Big Dipper sets, though, Cassiopeia rises. This is a pattern of five stars in a distinct W shape which lies directly across the North Star from the Big Dipper. Look for Cassiopeia high in the north on fall and winter evenings.  

Autumn represents sort of an ‘intermission’ in the sky, with bright summer stars setting at dusk, while bright winter stars such as Orion have not yet risen.  The ‘teapot’ of Sagittarius sets in the southwest early in the evening. The Summer Triangle is high in the west. Meanwhile, the Great Square of Pegasus is in the east, indicating that autumn has begun. The stars rising in the east are much dimmer than those overhead and in the southwest because when you face east at dusk in October, you face out of the Milky Way plane. The center of our Galaxy lies between Scorpius and Sagittarius, while the Summer Triangle is also in the galactic plane. Pegasus, on the other hand, is outside the plane of our galaxy and is a good place to look for other galaxies. Nearby constellations Andromeda and Triangulum (a small triangle) contain the spiral galaxies nearest to our own. 

Total Lunar Eclipse October 8 + Partial Solar Eclipse October 23!
The Full Moon of October 8 enters Earth’s shadow completely, causing a total lunar eclipse!  Partial eclipse begins at 4:15 am, with totality from 5:24 to 6:25 am. The Moon then begins to leave the shadow, but is still partially eclipsed as it sets at 7:26 in Houston. This is the second of four total eclipses we can see in 2014-15; the next one occurs April 4, 2015.

The New Moon of October 23 partially blocks the Sun, causing a partial solar eclipse!  For us, the eclipse begins at 5:00 and is still in progress at sunset (6:43 pm). For both eclipses you’ll need a site with a clear view to the west to watch the setting Moon or Sun in eclipse.

Celebrate The George October 10-12!
The George Observatory celebrates its 25th anniversary the weekend of October 10-12!  That weekend, the observatory is open for a members event on Friday evening and Sunday night in addition to our customary Saturday night hours

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.

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 southwest at dusk. This month and next, Mars approaches Saturn more and more. 

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.

Jupiter is behind the Sun and out of sight this month. 

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, the brightest star of Scorpius, the Scorpion, is in the southeast, with the ‘teapot’ of Sagittarius rising behind it. The Summer Triangle has fully risen in the northeast. The stars of summer are here.  

Moon Phases in July 2014:

1st Quarter: July 5, 7:00 a.m. 
Full: July 12, 6:26 a.m.
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.
