Seeing Stars with James Wooten: Mars aligns with Earth and sun, solstice on its way

seeing stars

Venus is in the west at dusk. At dusk, look high over the point of sunset for the brightest thing there; it outshines everything but the Sun and the Moon. 

Jupiter is also 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. During June, watch Venus gradually close the gap on Jupiter, until they are just over one-third of one degree apart on the evening of June 30.

Saturn is now in the southeastern sky at dusk. Although it is not as brilliant as Venus or Jupiter, it outshines the stars around it, so it’s also easy to see. 

Mars is lost in the glare of the Sun. Conjunction (Mars in line with Earth and Sun, behind the Sun) is June 14.

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. Venus and Jupiter come together right in front of Leo’s face, marked by stars in the shape of a sickle, or a backwards question mark.

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

Moon Phases in June 2015:

Full: June 2, 11:19 a.m.

Last Quarter: June 9, 10:42 a.m.

New: June 16, 9:05 a.m.

First Quarter: June 24, 6:03 a.m.

At 11:38 a.m. on Sunday, June 21, the sun is directly overhead at the Tropic of Cancer, the farthest point north where it can be overhead. This puts the Sun as high as possible in our skies, and marks the summer solstice. Of all the days of the year, we’ll have the most daylight and the least night on June 21. In the southern hemisphere, the sun is as low as possible in the sky as they experience the least daylight and the longest night of the year. It’s the winter solstice down there.

Due to the equation of time, the latest sunset occurs for us on June 30, not June 21. Thus, if we sleep through sunrise and watch sunset, as most of us do, days seem to lengthen all the way to the end of the month.

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 June evenings.

Clear Skies!

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!

Seeing Stars with James Wooten: Come out to the George for Astronomy Day November 8!

This star map shows the Houston sky at 8 pm CDT on November 1, 7 pm CST on November 15, and dusk on November 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 left.   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 the teapot of Sagittarius. Mars continues to fade a little each night as Earth continues to leave it farther behind

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) was on October 25.

Saturn is also out of sight behind the Sun this month. Conjunction with the Sun is on November 18.

The Summer Triangle now shifts towards the west as the Great Square of Pegasus appears higher, approaching the zenith. As the autumn ‘intermission’ in between the bright stars of summer and winter continues, Houstonians with a clear southern horizon can try to find a star that few Americans get to see. Due south and very low to the horizon at about 10:00 pm in mid-November is Achernar, 9th brightest star in the sky. It marks the end of the river Eridanus, one of the dim watery patterns that fill the southern autumn sky. If you can find it, Achernar will seem of average brightness because it is shining through so much air. Still, it is a good way to remind yourself that the stars we see depend on our latitude, and that the sky on the Gulf Coast is similar to, but not the same as, what most Americans see.

There’s a Partial Solar Eclipse Happening October 23: Here’s what you need to know to see it!

 

There’s a partial solar eclipse happening Thursday, October 23 and you can see it all from Houston*!

 The New Moon of Thursday, October 23, 2014, aligns with the Sun and the Earth well enough to cast its shadow towards Earth. However, no one will see a total eclipse for two reasons. First of all, the Moon was at apogee (greatest distance from Earth) on October 18, and is therefore smaller than usual in our sky. As a result, it is not quite big enough to cover the Sun, and the only eclipse possible would be an annular eclipse. Also, the Moon shadow is aligned to a point in space just over the Earth’s upper limb, so nobody will even get to see an annular eclipse. The near miss, however, allows the penumbra, where the Moon partially blocks the Sun, to land on the Earth. With North America near the upper limb of the Earth at the time, Houston will be within the penumbra. Therefore we will see a partial solar eclipse, in which the Moon will cover almost a quarter of the Sun’s disk at most.

partialeclipse

At 4:59pm CDT, look for the Moon to take a ‘bite’ out of the Sun’s disk. The Moon covers the northern limb of the Sun, which is the right side of the Sun as it sets in the west. Maximum eclipse, with the Moon covering almost 1/4 of the Sun’s disk, is at 5:58.  At 6:43, the Sun sets while still in partial eclipse. After this, the next partial solar eclipse visible from Houston occurs August 21, 2017. 

ECLIPSE TIMES

Eclipse begins: 4:59 PM, CDT
Mid-eclipse: 5:58 PM
Sunset: 6:43 PM

The Museum’s own George Observatory in Brazos Bend State Park will be open to the public from 1:00 -6:00 p.m. on October 23 for observing the Sun and, starting at 5:00, the eclipse.  

*CAUTION: Never look directly at the Sun with the naked eye or through an unfiltered telescope. Permanent eye-damage will result.
