Seeing Stars with James Wooten: Saturn and Perseid meteors bright in August

Star map Aug

Saturn is now in the south-southwestern sky at dusk. It outshines the stars around it, so it’s also easy to see.

Mars emerges into the morning sky this month. Look for it low in the east at dawn.  Mars remains dimmer then average, though, and won’t rival the brighter stars until next spring.

Venus and Jupiter are in line with the Sun and out of sight this month. Venus emerges into the morning sky fairly quickly, though; try looking for it low in the east at dawn the last week of August.

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 southwest at dusk.

Antares, brightest star of Scorpius, the Scorpion, is in the south, with the ‘teapot’ of Sagittarius to its left. Saturn is to the right of the scorpion’s head. The Summer Triangle is almost overhead. The Great Square of Pegasus now rises soon after dusk, indicating that despite this 100 degree heat, autumn is on the way.

The annual Perseid Meteor Shower peaks every year in mid-August—this year on Aug. 13. Remember that this is a shower, not a storm; you can expect a meteor per minute on average. Also, Earth is actually running into the meteor stream, rather than the meteors running into us. This means that the shower gets better as you get closer to dawn. Our George Observatory will be open late Wednesday night, Aug. 12, until 2 a.m. and Thursday, Aug. 13, for viewing the Perseids. 

For the Planetarium schedule, see www.hmns.org

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 August evenings.

Clear Skies!

 

Seeing Stars with James Wooten: The Stars of Summer are Here

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.  Venus now moves away from Jupiter as they both gradually become lost in the Sun’s glare

This is the last month to observe the two brightest planets in the western evening sky. On June 30, Venus overtook Jupiter. This month, watch Venus shift to the left of Jupiter each evening at dusk. Meanwhile, both planets appear lower and lower to the horizon each night, until they are both lost in the Sun’s glare by the end of the month. At dusk, look over the point of sunset for the brightest objects there; Venus and Jupiter outshine everything but the Sun and the Moon.

Saturn is now in the southern 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 remains lost in the glare of the Sun.

The Big Dipper is above and 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 southwest at dusk. Leo, the Lion, sets in the west at dusk.

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 July 2015:

Full July 1, 9:20 pm; July 31, 5:43 am
Last Quarter July 8, 3:24 pm
New July 15, 8:24 pm
1st Quarter July 23, 11:04 pm

At 2:41 pm on Monday, July 6, Earth is as far from the Sun as it will get this year, a moment known as aphelion. Remember, though, that the difference between aphelion and perihelion (in January) is small (only about 3%). Earth’s 23.5 degree tilt on its axis is a much more important effect. That’s why we have all this miserable heat and humidity now, rather than in January.

Just before 6:50 am CDT on Tuesday, July 14, the New Horizons spacecraft makes its closest approach to Pluto. As this is our first opportunity ever to gather real data from Pluto and its moons, astronomers are quite excited. The craft is already close enough to take some pictures, which you can see here. The Museum will have special activities for this occasion; email me if you want more information.

The Full Moon of July 31 is the second one of the month. That’s one of the definitions of a Blue Moon.

Planetarium Schedule:

Brazos Bend State Park, where our George Observatory is sited, has been closed since May 27 because the rains of Memorial Day and of Tropical Storm Bill caused the Brazos to overflow. The park plans to reopen on a limited basis July 8, making July 11 the first Saturday available for public observing.

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.

Get wet, go wild, or blast off with new Party Smarty birthday themes at HMNS

by Karen Whitley

Yikes! Is it May already? Time has flown by and now your child is about to turn another year older. Between work, school, dinner, errands, and that never-ending laundry, who has time to plan a party? Lucky for you, that’s what we’re here for! Not for the laundry (you’re on your own with that), but the Houston Museum of Natural Science is the place to call for giving your child a birthday experience he or she will never forget. We have hosted over 3,000 birthdays here at the museum, so we know a thing or two when it comes to parties. This year we are excited to announce that we are offering three new Party Smarty themes at our Hermann Park location: Shark!, wildlife, and Mars expedition!

Shark- Touch Tank 2 (2)

Sharks have always fascinated us land-dwellers, and they continue to hold millions of people across the nation in thrall each year in July. If you have your own shark-lover at home, now’s your chance to become the coolest parent around by throwing your kid aShark- Great White2 (2) birthday party with real sharks! Not only will they get to learn about great white sharks,
see the jaw of a megalodon, and actually get inside a shark cage, but they will also get the chance to touch live sharks in our Shark! touch tank experience. As an added bonus, each kid will get a one-of-a-kind button declaring that they touched a shark. Shark! will be leaving our museum in September, so make sure to grab this chance before it swims away!

Wildlife 7 (Swan Lake) 2Did you know that a ringtail cat is not a cat? Or that a bald eagle has 7,000 feathers? With our Texas wildlife theme, your birthday group will get the chance to hop along with robins and howl with coyotes as you explore the diverse habitats and wildlife that our great state Wildlife 8 (Ocelot) 2has to offer. From soaring falcons to roaming American buffalo, there are more than 250 types of animals in the Farish Hall of Texas Wildlife! Will you be able to find the flying squirrel? Now you and your guests can experience the American wild from dawn to dusk as you listen to the calls and sounds of our animals with the rising and setting of the sun.

Looking for something special for your pre-teen or teenager? Our Expedition Center theme is a great way to get them away from their video games and into a thrilling simulated flight to Mars! This is no pleasure cruise: your teen and friends will have to work together to Expeditionsuccessfully complete their mission to land on Mars. From piloting and navigating to building probes, experiments, and so much more, everyone will have a blast on this voyage into uncharted territory.

For more information about all of our basic and deluxe Party Smarty themes and packages, visit us here.

Seeing Stars with James Wooten: Lunar Eclipse on April 4

april stars

Mars remains in the west at dusk this month as it moves through Aries. Mars continues to fade a little each night as Earth continues to leave it farther behind. Later on this month, Mars begins to be lost in the glare of the Sun.

Mercury enters the evening sky as Mars leaves it. By April 30, Mars will be gone but Mercury will be low in the west northwest, near the Pleiades star cluster.

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

Jupiter is now high in the sky, almost overhead, 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 is in the southwest at dawn.

Brilliant winter stars shift towards the west during April. Dazzling Orion is high in the southwest at dusk. His three-starred belt is halfway between reddish Betelgeuse and bluish Rigel. Orion’s belt points right to Aldebaran in Taurus the Bull. Above Orion are the twin stars Castor and Pollux, marking the heads of Gemini, the Twins. Jupiter is among the Twins this month. You can find Sirius, the brightest star we ever see at night, by drawing a line from Orion’s belt towards south (left as you face west). Forming a triangle with Betelgeuse and Sirius is Procyon, the Little Dog Star.

Joining the winter stars are stars of spring in the south and east. Look for Leo, the Lion almost overhead at dusk. In the east, extend the Big Dipper’s handle to ‘Arc to Arcturus’ and then ‘speed on to Spica’.

Moon Phases in April 2015:

Full April 5, 7:05 am

Last Quarter April 11, 10:44 pm

New April 18, 1:56 pm

1st Quarter April 25, 5:55 pm

The Full Moon of April 4 passes through the Earth’s shadow, causing a total lunar eclipse. Unfortunately, the Moon clips the edge of the Earth’s shadow, allowing for only 5 minutes of totality. What’s more, for us the eclipse occurs near moonset and sunrise (which are almost simultaneous when there is a lunar eclipse). That puts the Moon low to the horizon during the eclipse; only those with clear views all the way to the western horizon can get a good look. It also means that totality falls during morning twilight.

Eclipse times:

Partial eclipse begins: 5:15 am
Totality 6:57-7:02 am
Moonset (still partially eclipsed) 7:13 am

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.
