A Week Full Of Fall Celestial Events

Posted by GearGalaxy Experts on

Thats right boys and girls, this week is chock full of spectacular celestial events that you'd be crazy to miss. There's somethinig for every stargazer this week and the best part is you dont need top of the line glass to enjoy these occurences (although it does help ).

Thursday October 23rd – Zodiacal Light

Do not miss this one! If you live in the Northern hemisphere, keep a look out about an hour before sunrise. This rare celestial event may look like the lights from a nearby city but dont be fooled.  If you're lucky enough to catch a glimpse of it, keep a look out on your eastern horizon and you should see a bright pyramid of light like the picture above.

Thursday October 23rd – Partial Solar Eclipse

 This day is without a doubt an astrological double whammy. Depending on how east or west you are in the US, you should see this awe inspiring eclipse from mid-afternoon untll sunset. Also something to point out is the farther north you are, you will see more of the sun covered by the moon.

Saturday October 25th – Last Glimpse of Saturn

Its safe to say us stargazers have been extremely spoiled by being able to see Saturn in the sky this summer. Bust out your binoculars and take a look at the 4 o'clock of the moon around dusk to give our favorite ringed planet a nice farewell before it slips into the suns glare.

Comet ISON: A Thanksgiving Day Spectacular

Posted by Will Schueneman on

Comet ISON

Comet ISON Oct 8, 2013

This year astronomers all over the world will have something different to be thankful for on Thanksgiving. The well-known comet ISON will come the closest it will ever get to the sun. ISON has never been to the inner-edge of our solar system before. It has been traveling for approximately 5.5 million years to reach us from the far edges of our galaxy, and on Thursday Nov. 28th, Thanksgiving Day, it will finally reach its closest point to the sun.

For those of you who don’t know a comet is typically made of dust, rock and ice. When a comet moves closer to the sun, the ice particles are vaporized and take the dust with it causing the effect of a “tail” behind the now only rock mass. The comet ISON was discovered over a year ago in Sept 2012 by a pair of Russian astronomers. Since then, ISON has been shedding some mass on its journey toward the sun. Currently, it's estimated that the comet is around 1.2 miles wide. Back in July of this year it was estimated that ISON was about triple that size.

It is projected that on Thanksgiving Day when ISON makes its trip around the sun that three possible outcomes could occur. First, is that the comet’s mass will be strong enough and hold up and will produce a fairly bright tail that could be visible to the naked eye to early morning sky viewers. Second, the sun could break up ISON into several smaller chunks which still would be awesome to witness. And third, the comet could be so weak that the sun could just completely disintegrate it into nothing.

Should ISON survive its pass around the sun, be on the lookout for a spectacular show in the first or second week of December. If you wish to try and see the comet during this time all you would need is a pair of binoculars, and maybe not even those. If you have a telescope that would be even better and would give you a much clearer picture. Best locations to view ISON would be any place where it is dark and away from artificial light.

Why is it important? When it comes to the solar system there are a lot of unknowns. As “Star Trek” stats, it is the final frontier. ISON gives us a glimpse of what our solar system was like 4.5 billion years ago. One step closer to unlocking some secrets of our great big solar system.

International Observe the Moon Night

Posted by Will Schueneman on

International Obersve the Moon NightDon’t be surprised if you see a lot of people outside at night with telescopes looking up at the night sky. For three years now, on the same night of October 12th people have been going out at night and observing the closest neighbor to Earth. On September 18, 2010 the International Observe the Moon Night (InOMN) was formed for professional and amateur astronomers to study the moon and share their knowledge with one another.

Ever since 2010 this annual event has grown in dramatic fashion. Today nearly 300 events will be orchestrated in over 40 countries in such places as observatories, high schools, colleges, NASA organizations and of course whoever wants to throw their own little backyard soiree. The InOMN is sponsored by multiple astronomical and NASA organizations and is considered to be an educational outreach program. Some people might ask why have this event in October on this particular date and why not have it in the summertime when it is warming and people are more willing to stay outside later at night. Well, the reason would be at this time of year is during the waxing gibbous phase which is supposed to enhance the visibility of the lunar craters on the moon.

For someone like me still being new to astronomy, this is an excellent opportunity for me to branch out and learn as much as I can about the moon. With events going on all across the country and in many other countries it would be easy for me to seek out and learn from someone who is knowledgeable in this subject. And the great thing is, if I didn’t want to go outside I can find an event streaming live on the internet and still learn a few things. So, remember tomorrow night, October 12th make sure you don’t miss out on International Observe the Moon Night and find an event near you. You would be surprised at some of the neat things you could learn.

Autumn Equinox: The First Day of Fall

Posted by Will Schueneman on

September 23 marked the first day where we officially left the Summer season behind and began the Autumn season, more commonly known as Fall.  But, what some people probably don’t know is why.  This year on September 22, at 20:44 UTC (Coordinated Universal Time), or 4:44PM EST, the Autumn Equinox occurred, which means in nearly every part of the world daytime and nighttime were approximately the same length.

Autumn Equinox

The Latin term for “Equinox” means “equal night”.  Every year there are two equinoxes, one happens in March called the Spring Equinox, and the other that happens in September.  Each time for that day only there is approximately 12 hours of sunlight and 12 hours of nighttime.  The reason these two equinoxes happen is because on those two days alone, the Earth’s axis tilts neither away from nor towards the sun.  Every other day of the year the axis has a slight tilt one way or the other making day or night longer than the other.  The exact moment when the sun crosses the celestial equator is when these equinoxes occur. (timeanddate.com)

So what does all that technical jargon mean?  Start expecting the sun to rise later and later every morning and set earlier and earlier every evening.  For the northern hemisphere we changed seasons from summer to fall, and for the southern hemisphere it is changing from spring to summer.

Personally for me Fall is my favorite time of the year.  So many different things are happening, football started, hunting season is right around the corner, the weather is comfortable, and the leaves will start changing soon.  The time for camping or grilling out with family and friends is now, with late night bon fires and maybe even a smore or two.

Don Quixote: Asteroid or Comet?

Posted by Will Schueneman on

Halley's Comet

Halley’s Comet

Stretching out as far as the orbit of Jupiter, the once known asteroid named Don Quixote appears to be more than what it was originally thought to be.  This large near-earth asteroid has been wondering around for 30 years keeping to itself, now appears to be a comet instead.  Astronomers from Northern Arizona University have discovered a faint coma around Don Quixote and what appears to be a tail behind it.

For those of you who don’t know, there are two main differences between an asteroid and a comet, chemical composition and orbit.  Asteroids are made up of a chemical composition that does not produce an atmosphere, while comets have a nucleus composed of volatile material that loosens nearer to the sun which gives it a coma appearance along with a thin transient atmosphere.  As far as the orbit goes, an asteroid has an elliptical orbit in which its distance from the sun does not vary too much.  A comet has an eccentric orbit causing its distance from the sun to vary greatly. 

Upon further research using NASA’s Spitzer Space Telescope astronomers have discovered carbon dioxide emissions and presumably water ice about 11 miles long on Don Quixote using Spitzer’s infrared wavelengths.  This gives Don Quixote the chemical composition needed to be a comet.  The tail discovered behind it gives the impression that its orbit is not elliptical but rather eccentric.  The exciting news about this discovery is it implies that water ice and carbon dioxide may exist on other near-Earth asteroids as well, which can open up a lot of doors and possibilities when exploring the unknown of space.

10 Year Anniversary for the Spitzer Telescope

Posted by Will Schueneman on

Spitzer TelescopeThe Spitzer Telescope celebrated a momentous occasion a few days ago.  On August 25 at 5:35 AM of this year, the infrared telescope celebrated its tenth birthday in space.  For a whole decade Spitzer has been orbiting our planet keeping a watchful eye out in the furthest parts of the galaxy and bringing us back phenomenal images and information that have helped us understand the universe just a little bit better.  With its infrared vision, Spitzer can see things other telescopes can’t in the far, cold, and dusty side of the universe.

The Spitzer telescope was originally called the Space Infrared Telescope Facility.  After it launched in 2003 it was renamed to Spitzer in honor of astronomer Lyman Spitzer who was considered to be the “father of space telescopes”.  Many astronomers might remember Spitzer surprising the world by discovering the largest of Saturn’s rings.  This giant ring is made up of a wispy band of ice and dust particles that Spitzer was only able to pick up due to the glow of heat that it gives off.  Another discovery that Spitzer made that some say was its most astonishing find came from outside of our solar system.  It was able to detect light coming from a planet, the first telescope to do this.  Many astronomers were thrilled with this discovery because it was originally not in Spitzer’s design to do this.Spitzer

The Spitzer Telescope has counted stars, investigated planets and galaxies, studied asteroids and comets, and discovered volleyball shaped spheres of carbon in space (known as buckyballs).  Even the United States hopes to utilize Spitzer to achieve his goal of visiting an asteroid by the year of 2025.  I think it is safe to say that over the past decade we have made drastic steps in exploring the furthest parts of the universe, and a big reason for that is the Spitzer Telescope.  It makes me excited and anxious about the discoveries the next ten years will bring.

Perseid Meteor Shower

Posted by Will Schueneman on

All you astronomers out there, did you get a chance to get your telescopes out and see the famous Perseids Meteor Shower that happened last weekend?  I missed it this time but you can be sure I won’t miss the next one.  It was recorded that the meteor shower peaked on the mornings of August 11-13.  In past years it has been known for this meteor shower to produce anywhere from 50 to 100 meteors per hour, and that the amount of meteors increase as it gets later into the night and early morning.  I recently found out, and will be interesting to those who are constellation enthusiasts, that the Perseid Meteor Shower radiates from a star in the constellation Perseus the Hero, hence the name “Perseids Meteor Shower”.

I recently started an interest in astronomy within the past year.  So I am, what some consider, to be an amateur.  The whole unknown part is what really drew me to it.  To think that we have only explored a small fraction of the universe,

Perseids Meteor Shower

with the endless possibilities that could be out there.  When I was little, telescopes used to be very expensive so it wasn’t until recently my interest in astronomy started.  Telescopes are actually quite affordable now.  Even some of the best brands like Celestron and Meade have telescopes under $100.

So, if you missed the Perseid Meteor Shower last weekend don’t worry, they happen at the same time every year around August 12th.  If you’re like me and you don’t want to wait that long, just keep your eyes up in the sky in the beginning of October.  The Draconid Meteor Shower is scheduled to peak around the nights of October 7-8.  This meteor shower is not as big as the Perseids but some years have recorded up to 100 meteors in a single hour.

Astronomy News Probably Has you Interested in Exploring

Posted by AdamC on

The news is abuzz recently with excitement over a brand-new picture of the infant universe, the Voyager II leaving the solar system, and a slew of new and exciting space exploration. Could this be the rebirth of an age of scientific wonder and excitement? I sure hope so. Since I was a kid, the universe has fascinated me, and I counted that interest amongst my hobbies. But technology is screaming along at a faster pace than any of us can keep up. I’m sure you’ve seen the post about beginner’s astronomy. It’s a fantastic guide and a great place to start.

Truly, just never stop following the news about the stars. Plus, telescopes are cheaper than ever before, so there’s really no reason not to have at least a beginner’s telescope pointed to the heavens. Try taking a peek at Jupiter, for instance. I’ve read some articles recently that have suggested that Jupiter’s moons may be the best option for human exploration and colonization in the solar system. That’s all speculation of course, and probably outside of the reach of our lifetimes, but why not look at the planet in all of its giant red spot glory?

Maybe you know of someone who is just starting out. We all remember that time, when the sheer size of the universe was enough to leave us in awe and wonder. Maybe you still feel that way (I sure hope you do). Just keep looking up, and check back here for more great stuff to help you along the way.
