Star Map September 2016

Venus is a little higher in the evening sky this month.    Look low in the west in evening twilight.

 

Mars and Saturn are now in the southwest at dusk. 

 

Mars continues to fade each night as Earth leaves it farther and farther behind.  Also, it moves faster than Saturn against the background stars, so you can watch Mars pull away from Saturn this month.   

 

Jupiter is behind the Sun and out of sight this month.  Conjunction (Jupiter directly behind the Sun) is on September 26.  

 

The Big Dipper is to the 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 to its left.  Saturn is right above Antares.  The Summer Triangle is almost overhead.  The stars of summer are here.  Meanwhile, the Great Square of Pegasus is high in the east at dusk, and is fully risen by month’s end.  Autumn is here.

The New Moon of September 1 blocks the Sun, causing an eclipse.  However, the Moon is too far away at the time to block the Sun completely, resulting in an annular rather than total eclipse.  Further, the whole event happens at night for us and is visible only in Africa. 

 

At 9:21 a.m. CDT on Thursday, September 22, the Sun is directly overhead as seen from the equator.  This marks the Autumnal Equinox, the ‘official’ start of fall.  On this date, everyone on earth has the same amount of daylight and night.  After this date, night becomes longer than day for us in the northern hemisphere.  Below the equator, day now becomes longer than night, and spring begins. 

 

This makes September one of the best months to observe an interesting effect.  You may have noticed that the spot where the Sun sets on the horizon varies day to day.  This variation is greatest, however, near the equinoxes in March and September.  Therefore, if you watch the Sun set each evening you can this month, the change will be quite noticeable. 

 

Come see us Saturday nights at the George Observatory!  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.

Jupiter is now in the west at dusk. It outshines all stars we ever see at night, so you can’t miss it.

Mars and Saturn are now in the south at dusk. As you watch them, Mars is to the right and is much brighter.

Although Mars continues to fade each night as Earth leaves it farther and farther behind, this month Mars still outshines all of the stars and even rivals Jupiter in brightness! By the end of the month, Mars begins to approach Saturn.

Venus is lost in the Sun’s glare and out of sight all month.

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 west at dusk. Leo, the Lion, is also in the west at dusk.

Antares, brightest star of Scorpius, the Scorpion, is in the south, with the ‘teapot’ of Sagittarius to its left. Saturn is right above Antares. The Summer Triangle has fully risen in the east. The stars of summer are here.

At 11:00 am on Monday, July 4, Earth is at aphelion. This means that on this date Earth is as far from the Sun as it will get this year. But all of us can feel how hot and sticky it is outside now, compared to January, when Earth was at its closest. This is because the Earth’s orbit is almost a circle; the difference between closest and farthest distance from the Sun is small. Indeed, Earth is only 1.6% farther than average from the Sun on July 4. The effect of Earth’s 23.5 degree tilt easily dominates the tiny effect of Earth’s varying distance from the Sun.

Also on July 4, the Juno spacecraft enters Jupiter orbit. For just over a year and a half, Juno will execute 37 orbits of Jupiter before a controlled orbit into Jupiter in February 2018. The spacecraft is designed to explore the inner composition of Jupiter, giving more information about what’s far beneath the cloud layers we see.

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. As of now, however, George is closed while Brazos Bend State park dries out from yet another round of floods on the Brazos River. The park could reopen as early as July 12.

Clear Skies!

Now Open: The Burke Baker Planetarium, Best in the World

It only takes a few seconds of a stellar light show in this newly-renovated facility to recognize why the Houston Museum of Natural Science is calling the Burke Baker Planetarium “the best and brightest in the world.” The clarity, the detail, the movement, the science, the imagery, all come together to create one of the most spectacular visions of the night sky you’ve ever seen, inside or outside the city. Part teaching tool, part adventure, a show at the planetarium is nothing short of magic.

A seat in the Burke Baker Planetarium is like a seat on the edge of space.

The power of the visual feast is due to the combined renovations of the theater and the projection system. With the specialized dome in place, the Digistar 5 laser projection system now has a surface on which to display its full potential. Ten Sony projectors that shoot across the dome at different angles combine to create one giant 360-degree image with more than 50 million unique pixels, or twice the size of the largest movie theaters. Laser projection means bright, vibrant color, and a frame rate of 60 frames per second means this system displays close to what the eye sees in reality looking up at the night sky. The only thing is that this picture is clearer.

This projection might as well be a photograph of deep space from the Hubble Telescope!

Take a look at some of the shots of the theater we took during today’s grand opening demonstration for a sneak peek, but don’t hesitate to come out and see for yourself. It’s the closest you can come to flying in space without actually suiting up!

That’s not hyperspace; that’s the dome theater!

See the constellations like the Greeks imagined them!

NASA Astronaut Mario Runco introduced the Burke Baker Planetarium during our grand opening event Friday. Runco did physics research on the International Space Station using toys in space. Only the Burke Baker Planetarium has views of space like Runco has seen.

Rome wasn’t built in a day, and neither was the renovated Friedkin Theater. Take a look at this time-lapse video that shows how much work we put into installing the dome!

Making the Stars: A Brief History of the Burke Baker Planetarium

In July of 1964, the Houston Museum of Natural Science opened its new museum in Hermann Park with modest exhibit space and the Burke Baker Planetarium. A state-of-the-art Spitz Space Transit Planetarium dominated the theater’s center with its flat floor and a few slide projectors. Two star balls connected by cages, swinging in a yoke, generated the moving stars and planets. All programs were live star tours.

That year the Houston Independent School District began sending students to the Burke Baker Planetarium. In the last 50 years, over a million HISD children have explored the starry night in an experience reaching every HISD student at least once.

For an idea of what the planetarium experience was back in the 1970s, take a look at my first Burke Baker Planetarium brochure. The brochure was a 3-fold with the front and back cover shown below. The address was 5800 Caroline Street. When you called for reservations, you only used seven digits. The museum was free, but the planetarium cost $1 for adults and 50 cents for children. We did two or three shows a day plus morning school shows and thought we were busy. Now we do 13 to 16 shows each day. Notice the map. The passage between the planetarium and the tiny museum was a glassed-in breezeway.

Inside the brochure was a description of the planetarium experience. Burke Baker’s gift has now brought the astronomy experience to more than 7.5 million people, including all upper elementary students in the Houston Independent School District since 1965.

Below is the fold over section showing our new Margaret Root Brown Telescope, which is still behind my office on the third floor. We need an access across the roof to open it up to the public once again as well as realuminizing of the mirror. The telescope tracked the sun automatically and sent a live image to the planetarium and the Energy Hall in the lower level. We created five new shows each year, but they were much easier to produce than the two new shows we do now.

In 1988, the Burke Baker Planetarium was one of the first in the world to go digital. In a capital campaign that funded the Wortham Giant Screen Theatre, the planetarium’s Friedkin Theater became a space simulator with an Evans & Sutherland Digistar 1, the world’s first digital planetarium projection system.

In 1998, a decade later, the Burke Baker Planetarium was first in the United States and second in the world to install a Digital Sky full-dome digital video projection system. This dynamic immersive environment was funded by a grant from NASA through Rice University. Now the planetarium could offer full-dome animations and movies with a new slightly tilted dome and seats. The planetarium’s Cosmic Mysteries and Powers of Time were among the first full dome digital films produced.

Eighteen years later, the Friedkin Theater of the Burke Baker Planetarium becomes the most advanced True 8K planetarium in the world. On March 11, HMNS will unveil an overhauled theater featuring an all-new, tilted, seamless projection dome and the main attraction, the Evans & Sutherland Digistar 5 digital projection system. This cutting-edge system brings the highest resolution, the brightest colors, and the most advanced spatial imaging technology on the market to the planetarium, restoring its status as best in the world.

Editor’s note: Keep your eyes peeled for more details about the Planetarium renovation on social media, Facebook, Instagram, Twitter, and right here on our BEYONDbones blog. Throughout the month of February and early March, we’ll be posting the latest information about the project until the grand opening March 11.
