Seeing Stars with James Wooten: August 2013

Venus remains in the west at dusk. It outshines everything but the Sun and Moon, so you can begin observing it during deep twilight. As August ends, Venus begins to approach Saturn.

Saturn is now shining in the south/southwest at dusk. Although not as bright as Venus, it does outshine the stars around it, so you can’t miss it. Jupiter is higher in the morning sky this month. Look for it in the east at dawn.

Mars, much dimmer than Jupiter, now pulls away from it in the morning sky. Look for it to Jupiter’s lower left in the morning sky at dawn.

The Big Dipper is to the 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 south at dusk.  Leo, the Lion, sets in the west at dusk.

Antares, brightest star of Scorpius, the Scorpion, is in the south, with the ‘teapot’ of Sagittarius to its left. The Summer Triangle is high in the east. The stars of summer are here. Meanwhile, the Great Square of Pegasus begins to rise in the east, indicating that fall is near.

The Perseid meteor shower peaks on Monday morning, August 12, as it does every year in mid-August. As always, we see more meteors in the pre-dawn hours, because that’s when Earth rotates us into the meteor stream. The Perseids have a broad peak, meaning that quite a few meteors are visible for a few days before and after the best date.

Thus, you’ll still see quite a few meteors if you come to George Observatory on Saturday night, August 10 and stay into Sunday morning, August 11. We’ll be open until 2 am, long enough for the shower to get good. Keep in mind that this is a meteor shower with, on average, one meteor per minute, and not a meteor storm, which would average about one meteor per second.

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.

As big as it gets: Celebrate a super(moon) Cinco de Mayo at the George Observatory

The supermoon is this Saturday, May 5th, 2012.Something out-of-this-world — think celestial — is happening this Saturday evening. It’s the biggest, brightest moon of the year: the supermoon!

The last supermoon was over a year ago, but that was nothing compared to the sky show we’re about to watch this weekend. The moon on Cinco de Mayo will appear 14% larger and 30% brighter, with the maximum brightness at 10:35 pm CDT — just at the end of regular observation hours at our George Observatory in Brazos Bend State Park.

But you’ll get more than the moon when you look toward the stars this weekend! There will also be three planets in view (Venus, Mars, and Saturn), plus the peak of the Eta Aquarid meteor shower. These meteors are from the tail of Halley’s Comet and even with all the moon light, we might see a few fireballs.

That’s why you should come join us at the George Observatory to get your front row seat to this Moon de Mayo event. In addition to the celestial show, we’ll be screening 2012: Mayan Prophecies — a fabulous Cinco de Mayo astronomy story — in our Discovery Dome.

George Observatory events begin at 3:00 p.m. with a daytime viewings and showings in the Discovery Dome of 2012: Mayan Prophecies. Telescope viewing will begin at dusk and last until 11:00 pm.

This Cinco de Mayo, you owe it yourself to look up. Spend some quality time with the supermoon at George Observatory, and don’t miss this awesome astronomical event.

Go Stargazing! August Edition

This month the great planet race continues, as Venus, Mars and Saturn form a triangle in the west.  Watch the triangle change shape each night as Venus overtakes Saturn and then Mars!

Venus is by far the brightest of the three planets.  Face west at dusk and look for a point of light that outshines everything in the night sky.

Saturn and Mars are to the upper left of Venus as August opens.  Mars is below Saturn and a bit to its left.  Although these two planets of similar brightness are much dimmer than Venus, they outshine all the other stars near them.

Observe all three carefully throughout August and watch as their configuration changes.  Mars aligned with Saturn last Saturday (July 31) and now begins to move farther to Saturn’s left.  Venus, moving faster than the other two, continues to approach from the right; it will pass Saturn on August 8.  Venus then continues to gain on Mars as they both move away from Saturn.  Venus finally overtakes Mars on August 19-20.  On the night of August 31, Venus and Mars are to either side of the star Spica in Virgo.

Jupiter is now a late evening object, rising by 11 p.m now and by 8:45 p.m. at month’s end.  It outshines all stars in the sky, so it’s easy to find.  Face east in late evening or south southwest at dawn to see it.

The Big Dipper is in the northwest at dusk. You can extend the curve of its handle to ‘arc to Arcturus’ and then ‘speed on to Spica’.  These stars are in the west at dusk tonight.  Arcturus, by the way, is the fourth brightest star we ever see at night, but the brightest one Americans ever see on an August evening.  Spica is in Virgo, the constellation where this month’s ‘planet race’ occurs.

In the east, look for the enormous Summer Triangle, consisting of the stars Deneb, Vega, and Altair.   This triangle is up all night long from June to early August, hence its name.  Scorpius, the Scorpion, is in the south at dusk.  Sagittarius, the Archer, known for its ‘teapot’ asterism, is to its left.  Between these two star patterns is the center of our Milky Way—the brightest part of that band as wee see it.  On a cloudless night far from the big city, see if you notice the Milky Way glow near the ‘teapot’ of Sagittarius.  In late evening, look for the Great Square of Pegasus rising in the east.

Perseid Meteor 8/12/08

On Friday morning, August 13, the Earth passes through a stream of debris left long ago by Comet Swift-Tuttle.  This produces the Perseid Meteor Shower, one of the best meteor showers each year.   The Perseids occur every year at about this time, producing on average about one meteor per minute.  Keep in mind that even a short period such as a minute can seem longer if you are waiting for something to happen.  Since Earth is running into the meteors, not the other way around, the leading edge of the Earth encounters the shower.  This is the side going from night into day.  Accordingly, we see more meteors as dawn approaches.  Big city lights or the Moon can limit the meteors you see by dimming out fainter ones.  This August, however, the New Moon is on the 10th, giving us a skinny crescent on the 12th which sets long before the shower really gets going.  The main challenge, then, is to avoid city lights.

If skies that night are clear, our George Observatory will open Thursday night, August 12 at 9pm and remain open until dawn for observing the shower.  If you come out to George or go elsewhere, you’ll want to lie on your back (to see as much of the sky as at once as possible) and orient yourself towards the constellation Perseus.  (The shower is called the ‘Perseids’ because they seem to radiate from that constellation.)  Perseus rises in the northeast at dusk and is high in the north at dawn.

So here’s what went down after you logged off.

Tonight is the best time to view the annual Perseid Meteor Shower - check it out at the George Observatory, open all night, starting at 9 p.m. In the hours just before dawn, it’s possible to see a meteor every minute.

Your mother was right (about the solar system) – we are special.

In an effort to understand their contribution to global warming, 21 US cities will measure and disclose their carbon emissions as part of a global effort run by the Carbon Disclosure Project.

Proof that magic is often science in disguise: scientists have created an Invisibility Cloak that bends light to make objects invisible. Currently, it works on a nano-scale, but could soon be enlarged.

China’s massive cutbacks in pollution-producing industries in advance of the Olympic Games was intended to help athletes compete at their best – but it’s also giving scientists an opportunity to study what happens when “a heavily populated region substantially curbs everyday industrial emissions.”
