Great American Solar Eclipse

 

We had a great family adventure up to Nashville for the total solar eclipse (August 21, 2017).  We took lots of pictures leading up to totality, but decided to just experience the final moments without any electronics.  We all agreed it was the most profound and awe-inspiring natural wonder we've ever seen.  Already making plans for April 8, 2024.  We can't wait!

Messier 109

A couple weeks ago we had a lot of fun getting out the telescopes to share with friends and neighbors.  A beautifully clear (& mostly bug free) night allowed us to check out the moon, many star clusters and before we were done Jupiter rose into view and stole the show.  We can't wait to do it all again!

At the same time we were touring the cosmos, I had the astrograph set up capturing Messier 109 (above).  This is one of the faintest objects in the Messier catalog evidenced by over 4 hours total exposure time and precious little detail to see.  Although, if you consider that the light in this image began its journey to us when the dinosaurs roamed the Earth, maybe it's not so dim after all.  M109 is a beautiful barred-galaxy found near the bowl of the Big Dipper.  In fact, the incredibly bright star in the image is one of the main stars (Phecda) in the Big Dipper.

NGC 2403

NGC 2403 is 10 million light years away and is about half the mass of our own Milky Way.  The reddish clusters scattered around the arms are active star-forming regions.  At 10 million light years, the light from this galaxy began its journey long before humans walked the Earth.  It's incredibly humbling to think about entire geological and evolutionary epochs passing on Earth while this light was in transit, undisturbed, to the moment it entered my imaging system.  A true cosmic connection.

Messier 36

Messier 36 is the smallest of three star clusters in the constellation Auriga.  Though small, it is one of the prettiest with nice arrangements of stars spiraling out from the center.  Lying about 4,300 light years away, astronomers estimate it's age at 20 to 40 million years which is relatively young on the cosmic time scale.  The main cluster consists of predominantly bluish-white stars, but can you see the many reddish stars adorning the edges?

NGC 147 & 185

My last image of 2016 was a nice galaxy pair consisting of NGC 147 (oblong galaxy on the right) and NGC 185 (spherical galaxy on the left).  There is some debate among astronomers, but there is some evidence to support that these two galaxies form a binary pair meaning their gravities interact and also are considered satellites of the massive Andromeda Galaxy.

IC 342

On Christmas Night, we had some early clear skies that gave way to clouds rolling in from the south.  Before that happened, I was able to image IC342, the sprawling island universe pictured above.  Normally, something of this size and brightness at 10 million light years away would be easily seen, but it happens to lie in the plane of our own Milky Way galaxy.  So, we are viewing it through the dust, stars and gas of our own galaxy which renders it much more difficult to view.  Think cosmic light pollution.  Normally, light pollution is the arch-enemy of astronomy, but when its coming from our own galaxy it creates quite a sight!

SuperMoon - Ben's First Shot

As many of you know, this week we had the closest approach of the moon, at full, since 1948.  We had a great time watching it rise over the trees in our neighborhood.  Later in the evening, Ben and I got out the camera and tripod and Ben captured the beautiful image above.  Great work for his first official astrophoto!

Messier 15

This beautiful cluster is part of our home galaxy and revolves, as we do, around the galactic center of the Milky Way.  One orbit takes about 250 million years.  The cluster itself contains approximately 100,000 suns and there is debate about the center of the cluster.  Some astronomers believe that stars are actively collapsing toward the center to create a high-density environment.  Others believe that there may be a black whole lurking at the center.  Either way, it makes for a glorious sight!

NGC 7331 - Deer Lick Group

After a long and hot summer, we finally had two gorgeous nights last week with beautiful clear skies and overnight temperatures dipping into the 50's.  I was able to get out Thursday and Friday night to capture the image above.  NGC 7331 is part of the Deer Lick Group.  The main galaxy (NGC 7331) is at the perfect angle to give us a real sense of depth.  Do you notice the other four, much smaller, galaxies arrayed around it?  The difference in size is just an optical illusion. They are all of similar size, but are at much further distance from us.  NGC 7331 is about 40 million light years away while the others are 300 to 400 million light years distant.  In other words, the "smaller" galaxies are about 10 times further away.  It's a bit mind-numbing (& humbling) to contemplate light in this image representing vastly different ages of our universe.  One final note:  I had targeted this same group about three years ago (see below).  A lot of learning, skill building and equipment upgrades over the past three years shows a big difference (thankfully!).

Messier 58 and the Siamese Galaxies

My original intent with this image was to focus on Messier 58 (barred face on galaxy on right).  This 300,000 solar mass galaxy is beautiful all by itself, but the Siamese Twin (or Butterfly) galaxies in the upper left steal the show.  The twin galaxies are actively colliding and merging together with active star formation where they overlap.  Imagine the newly born star systems and worlds forming at this very moment.  The light captured in this picture is nearly 60 million years old.  What will it look like 60 million years from now when the light currently leaving the twins finally arrives to Earth?

The Markarian Chain - Messier 84 & Messier 86

The constellation Virgo is absolutely brimming with galaxies and perhaps one of the finest examples is the Markarian Chain pictured above.  Each nonpoint source of light is, in fact, a galaxy.  Named for the Armenian astronomer Benjamin Markarian who discovered they share a common motion (at least 7 appear to move together), this stunning chain of galaxies forms a beautiful curve through the night sky.  Messier 84 and 86 anchor the lower right portion of the chain.  M84 is the galaxy in the lower right corner and the next one up the curve is M86.

Transit of Mercury

Another celestial alignment occurred this morning as the planet Mercury passed between us and the Sun.  I was fortunate to have some breaks in the clouds and capture the image above.  I was also fortunate to share it with some students, colleagues and friends at the Test Track.  In the image above, Mercury is the very small, circular object in the lower half of the sun, the other amorphous blobs you see are sunspots.  It's incredible to see the Sun and Mercury like this as it forces our minds to consider the vastness of the Sun relative to Mercury and in turn, our own planet.  Mercury is about 40% of our own size, so if Earth were seen transiting in an image like this, we'd be a little over two times the small planet above.  In other words, incredibly small.  The next transit will be in November, 2019 and I hope to see it again.  After that, it won't occur again until 2032.  We'll hopefully have human exploration on Mars by then.  Stay tuned!

Moon Occults Aldebaran

Last night we had beautifully clear skies to see the moon occult the bright star Aldebaran.  An occultation is anything passes between an object and the observer.  In this case, the moon passed between us and the star.  We set up our telescope and binoculars so Jen and I could both view it in real time.  Since this was a blue-sky event occurring well before sunset (between 5:30 and 6:45 pm), it was pretty challenging to pick out the star in contrast to the brighter and larger moon in a sunlit sky.  At the eyepiece, it was absolutely stunning to see the star suddenly disappear behind the moon; like a light suddenly extinguished.  About an hour and 15 minutes later, Jen and I patiently waited for Aldebaran to rise over the lunar landscape.  We both were able to see it just as it popped back into view and then gain greater and greater separation from the moon.  To me it's simply staggering to think about this perfect cosmic alignment spanning 66.6 light years.  For about an hour, earth, the moon and this distant star formed a straight line stretching 391,140,000,000,000 miles.

The picture above was taken a little later in the evening, once the sky had grown more fully dark.  The moon is obvious and Aldebaran is in the lower right corner.  I thought about trying to capture Aldebaran as it just came back into view but figured I'd mess up the exposure and didn't want to miss it.  Seeing it live was well worth it!

Messier 95 & 96

Though the weather has been fantastic, it has been tough lately to get out imaging.  My latest adventure was to image a pair of galaxies (Messier 95 and 96).  In the photo above, M95 is on the left and M96 on the right.  Messier 95 is known as a "barred spiral" galaxy with an inner ring of active star formation.  It's neighbor, M96 is slightly larger, is a classic spiral galaxy and encompasses 80 thousand million solar masses.  These two galaxies are part of a three galaxy group known as Leo I Group in the constellation Leo.

NGC 2903

NGC 2903 is a fine example of a barred spiral galaxy in the constellation Leo.  The bluish clusters scattered along the spirals are young groups of stars while the pinkish areas are active star forming regions.  It's amazing to see creation in action, though the light is coming to us from 20 million years ago.  We'll have to wait another 20 million years to see what it looks like today. Ouch...That's one of those ideas that makes my head spin.

Messier 37

Messier 37 just became my favorite open cluster of stars.  Stare at it for a few minutes and patterns will start to emerge outside of the dense area of stars in the center.  Some famous astronomers have remarked:

"...wonderful loops and curved star patterns."
--Heinrich d'Arrest

"The whole field being strewed as it were with sparkling gold dust..."
--Charles Piazzi Smyth

What we are seeing is a beautiful collection of about 2,000 stars in this open cluster which lies at least 4,500 light years away from us.

IC 434 - Horsehead Nebula & NGC 2024 Flame Nebula

This image is my new personal favorite.  The names speak for themselves, though the names can't hope to capture the majesty of this scene.  As Dr. Ellie Arroway once said, "They should have sent a poet."

The Flame Nebula is being fueled by the intense star above it, Alnitak, an is an active star forming region.  The Horsehead is known as a dark nebula and what we see is actually a swirling cloud of dust and gases that contrast stunningly with the backdrop of ionized hydrogen gas behind it.

The soul nebula is an absolutely massive emission nebula that is an active star forming region.  It covers an area of sky equivalent to four full moons, but is so faint that it is very difficult to see through a telescope.  The image above was taken over a couple of nights with 5 hours of total exposure time and yet it still is somewhat elusive.  There is another nearby nebula, the Heart, which I hope to capture soon so I can put the Heart and Soul together.  Stay tuned!

This beautiful edge-on unbarred spiral galaxy is about how our own Milky Way would look from an edge-on perspective.  Curiously, if there was an observer looking at our galaxy from this one, they wouldn't be able to see us since that dark dusky lane that runs down the long axis would block light coming from us.

Messier 1 - The Crab Nebula

Nearly 1000 years ago, in 1054, a new bright star was visible to Chinese astronomers during the daytime.  While they were not able to see the nebulosity evident in this photo, the dying star that had gone supernova provided the remnants we are now able to see.  Curiously, sightings in Europe were probably censored as the Catholic Church took it as a bad omen.

The two images above are a study in contrasts.  Both set in very dense starfields, the top photo can be found in Cassiopeia and the gassy Pacman-shaped cloud is lit up by the bright central star.  The lower photo (Messier 39) is found in the constellation Cygnus and may be seen with the naked eye from dark locations.  To me, it looks like a beautiful set of jewels set against the majestic backdrop of the milky way.

I normally add some descriptions regarding the above images.  But I thought a nice change of pace would be to post some song lyrics that perfectly fit this time of year as the winter constellations come soaring into view.  These come from the band Beta Radio on their Darden Road album.  You can here the song at https://www.youtube.com/watch?v=k1f-ieI1Ols


Both the bears are in their chairs
They're sitting in your upper room
Each night they ascend the stairs
And point to the north with dipping spoons
I hear the seven sisters whisper
they know the place from where they came
Oh the hunter and the bull
Are made full beneath the lion's mane

Oh, all the stars align
for the second time
Oh, I drank the new design
for the second time

The brother twins each other lend
A hand around the upper pole
They drink the wine of the new design
That makes the broken-hearted whole
The dragon came as he did before
Tempting all into his door
He wears stars as his disguise
But a second time he will not rise

Oh, all the stars align
for the second time
Oh, I drank the new design
for the second time

Oh, Oh, Oh, Oh

Two Globs Around a Dumbbell (M71, M27 & M56)

Messier 71

Messier 27 - Dumbbell Nebula

Messier 56

After a long, hot and humid summer, I finally had some crystal clear skies last week and made the most of it.  Messier 71 & 56 were new targets while I had imaged Messier 27 (Dumbbell) a couple years ago.  M27 is such a beautiful target, it was fun to revisit.  

M71 & 56 are both globular clusters comprised of tens of thousands of stars, they look completely different mostly due to their relative distance to Earth and proximity to the Milky Way. Messier 71 lies within the Milky Way and is set against a beautiful dense background of stars while M56 is a bit more concentrated and enjoys a bit more isolated area of space.

The dumbbell nebula is stunning to view.  It's amazing that such order, structure and beauty can evolve out of a dying star.

NGC 4725

This galaxy is somewhat unusual in that it just has a single spiral arm.  Most spiral galaxies, like our own Milky Way, have two arms.  A quick internet search showed that this is a very popular astrophotography target, but didn't turn up much beyond the facts that it spans about 100,000 light years and is approximately 41 million light years from earth.  There are two other galaxies in this image.  NGC 4712 is closes while NGC 4747 looks to me like it's hurling toward the others with just a hint of afterburner.

Messier 53

After targeting primarily galaxies recently, I decided to check out a globular cluster last evening.  Messier 53 lies about 63,000 light years from us and, according to astronomers, is approaching at 70 km/sec.  That translates to a whopping 156,492 miles/hour.  Given the current distance and speed, Earth should have a close encounter in about 275 million years with this beautiful cluster.

Messier 106

We had a rare clear and cool Friday night with little moon on May 22.  Allison and I made the most of it and headed to our local dark site.  We had a great time, setting up at dusk and heading home at 1:30 in the morning.  While I was busy with the photography equipment, she did a great job running the large telescope herself and was able to see many new Messier objects.  In all, she logged 12 new ones and is well on her way to logging all 110.  Truly a night to remember.

The large galaxy in the image above is Messier 106 which, curiously, Messier may not have ever actually observed.  It was only added to the Messier list in 1948.  Other galaxies are clearly visible in the vicinity and astronomers believe M106 is the the center of a galaxy group of 17 objects.  The nearest and seemingly largest neighbor is NGC 4217 which happens to appear edge-on to our viewpoint.  The contrast and arrangement of these galaxies is simply stunning.

Messier 65 and Messier 66

This pair of galaxies resides in the constellation Leo that rides high in the southern sky, leading Virgo toward the west.  The galaxy to the left is M65 while M66 is on the right.  They are similar in size, about 90,000 light years across, though M65 is inclined at about 74 degrees to our line of sight making it look much more elongated.  While these do make a stunning pair, there is actually a third I wasn't able to get in a single shot that together comprise the "Leo Triplet".

Messier 100

Spring is the time for galaxies in the southern part of the sky and though we've had tremendous cloud cover, we finally had a nice stretch of clear weather.  I was able to get out a few nights last week with a new camera (see notes below) and had a lot of fun shooting images at -15C with an entirely different setup.  So, this is essentially "first light" for the new setup.  I think M100 was a beautiful target, graced by a number of additional nearby galaxies.  While appearing somewhat small in this image, consider that it is 107,000 light years across and contains 200,000 million solar masses.  This is comparable to our own Milky Way galaxy.  It's irregular spiral shape has been attributed to gravitational interactions with the nearby galaxies.

Messier 41

On the same night I visited the Orion Nebula (below), I also took advantage of the clear skies to target Messier 41.  The loose arrangement of stars in the foreground is a naked eye collection that may be one of the oldest documented deep sky objects.  Aristotle made reference in 325 B.C. to a "tail" near one of the stars in the Dog.  Some modern astronomers believe he was referencing this collection as it resides in Canis Major (the Great Dog).  See if you can find it yourself.  First, go outside and find Canis Major.  You will find this trusty hunting dog following Orion as he hunts.  Look to the east and south of Orion to find the brightest star in the sky (Sirius) which is the eye of Canis Major.  Look just a little bit down (mostly south) from Sirius to see if you can see this cluster.

After some time away from photographing the Orion Nebula, I decided to revisit a few nights ago.  What a difference a couple years of study, improved patience and equipment improvements will make!  The top image is the recent photo, while the lower was taken in November of 2013 for comparison.  Key differences with the new photo include more exposure time, using the full array of assorted frames (light, dark, flat, dark flat and bias), better understanding of post-processing, a more effective coma corrector and sky glow filter.  I also did a better job of framing the Orion Nebula and its neighbor, the Running Man.  This one is going on the wall!

California Nebula (NGC 1499)

The California Nebula (NGC 1499) now holds the record for the largest deep space object I've photographed.  This sprawling emission nebula is lit up by the by star in the lower center of the picture.  The nebula is so large that only about half of it is captured in this photo, the rest extends up and to the right and down and to the left.  Though appearing quite bright in this photo, at the eyepiece and in raw images there really isn't much to see.  It definitely requires a series of long exposures and some careful post processing to tease out the faint nebula structure.

Cave Nebula (Caldwell 9)

Another nebula I photographed over the holidays, but just now had a chance to process, was the Cave Nebula (C9).  This sprawling nebula complex contains emission, reflection and dark nebula.  The stars in this region are relatively young, some less than 100,000 years.

Cocoon Nebula (IC 5146)

The aptly named cocoon nebula lies in the constellation Cyngus.  It is both an emission nebula (gives off its own light as ionized gas) and reflection nebula (reflects light from other stars).  There is also a dark nebula trailing behind the cocoon, arcing up and to the right. To me the overall effect is simply stunning as the cocoon appears to have burrowed deep within this incredibly dense star field to await its metamorphosis.
