Insight Observatory Has Arrived!

  • May 29, 2017

SkyPi has the distinct honor of hosting a 16″ Dream Telescope a Newtonian Astrograph owned by Insight Observatory. Muir Evenden and Michael Petrasko spent a week on site with John for the installation. They were able to see, first hand, the beautiful and clear sky conditions our remote location has to offer. Thanks so much guys. We are happy you enjoyed your stay! John is a fabulous host! I am sad I was not able to be here as well. Jan

Below is a link to their blog that discusses their visit here at SkyPi.

AstroImage- NGC 6992, The Rest of the Veil Story – Bob Rieger

  • November 11, 2016
“The last astro image I recently sent was NGC 6960, the Western Veil Nebula.  As you may remember, it is a remnant of a supernova explosion that occurred to a nameless star in the constellation of Cygnus some 3,000 to 6,000 years ago.  The shock waves of gas from the explosion formed a spherical shell moving outwards from the dying star.  While most of the shock wave is invisible to us, several of it’s brighter arcs are detectable by the eye using special filters.  Photographically, the shock waves of oxygen, hydrogen and sulfur are readily detectible.
I mentioned in my last email my next image would be of NGC 6992, the Eastern Veil Nebula.  That image is attached, and while it is similar to NGC 6960, you can see differences in the amount of oxygen (blue) and hydrogen (red).  It is believed the shock waves are relatively thin.  This is what causes the appearance of filaments of gas, since they are only visible when they line up along our line of sight.  The twisting of the filaments are actually undulations in the surface of the spherical shock wave that is moving outwards.
In order to provide a bit of perspective, here is a small graphic from the internet which shows the entire nebula in infrared light, with the major structures indicated.  The approximate center is where the original star explosion occurred:
ngc6992
Now, when you examine my attached image, you can get a sense of the overall size as compared to the relatively small area I am imaging.  The entire nebula is believed to be some 70 light years in diameter, at a distance of almost 1500 light years.  This nebula resides in the next closest arm of our Milky Way Galaxy.
 ngc-6992-eastern-veil
By the way, when you look at the internet photo, and the names of the nebula, you will note a rather curious thing.  It is not a mistake, but can you see it?
Do you see the designations of East and West confused?  Well, they are not- it’s just a matter of reference.  On the surface of the Earth, East and West are defined by meridians of longitude running left or right from the prime meridian.  In the sky, the reference point is is not from the surface of the Earth, but rather an imaginary vantage point infinitely far away where the observer is looking DOWN upon the Earth.  Now you can see the familiar orientation of West and East being left and right, respectively!
Hope you enjoy my image of NGC 6992, the Eastern Veil.”

AstroImage- NGC 6960, A Celestial Wedding – Bob Rieger

  • November 11, 2016

ngc-6960“Our home observatory in Tucson was dismantled, and the telescope equipment was moved to a very dark sky location in Pie Town, New Mexico.  Our friends, John and Janet Evelan, own SkyPi Remote Observatory, and the equipment is set up and operational in one of their pod observatory buildings.  I now operate the telescope completely by remote control over the internet from my home in Rhode Island!  The technology is amazing, and with the help of John and Jan I can conduct great imaging under extremely clear and dark skies at an elevation of about 7900 feet.

So, the telescope has now seen first light, and I have captured and processed my first image at SkyPi Observatory.  The attached image is NGC 6960, the Bridal Veil Nebula.  It is a section of the much larger Veil Nebula, located in the direction of the constellation of Cygnus, the Swan.  The Milky Way runs right through Cygnus, and therefore this part of the sky is very rich in celestial wonders.
But let’s examine NGC 6960.  It is part of a supernova remnant.  About 15,000 years ago, an unknown star died in Cygnus.  It had exhausted it’s nuclear fuel, and after successively fusing elements up to Lead, it could no longer exert outward pressure against the ultimate force of gravity.  In a matter of seconds the star, which was about 8 times the mass of our own sun, detonated in an inconceivably monstrous explosion.  This explosion produced more light than a billion stars.  In fact, if our Cro-Magnon distant ancestors were looking at the night sky, they would have witnessed a new star visible even in daylight for a few months.
The shock wave of that star has been moving outward for the past 15,000 years at velocities of several million miles per hour.  Today, the spherical bubble of that exploding shell is about 80 light years across.  While it is extremely faint, several arcs of the shell are brighter, and can be imaged in visible light.  NGC 6960, the Bridal Veil, is one of 3 major bright arcs.  I don’t think the nickname of “Bridal Veil” needs much explanation- it is beautifully lacy and delicate.
When you examine the Bridal Veil closely, you can see a fantastic array of gas streamers twisting and turning.  The ferocious winds of the explosion pushed out the star’s matter, and as it slammed into other dense gas in the vacuum of space, mixing turbulence created the wonderful shapes we see today.  The various colors are created by ionized hydrogen, oxygen and sulfur.
The extremely bright star, 52 Cygni, is not part of the Veil Nebula.  The nebula lies at an estimated distance of 1470 light years from us.  52 Cygni is only 201 light years away, close enough for astronomers to have measured an accurate parallex distance.  52 Cygni is interesting in it’s own right.  Spectroscopic measurements indicate it really is a triple star system, although the star components are too close together to be imaged visually.  The primary component is about 8 times the diameter of our sun and some 80 times brighter.
NGC 6960 is also referred to as the Western Veil.  I am presently imaging NGC 6962, the Eastern Veil.  That will be the subject of the next astroimage.”

Women in Science: Maria Mitchell-Astronomer

  • August 29, 2014

Maria Mitchell (1818-1889)
Astronomer

Growing up in the whaling town of Nantucket, Massachusetts Mitchell grew up learning about the stars and navigation. She could rate the chronometers for whaling ships and plot the movements of the planets.

In 1847, her discovery of a comet invisible to the naked eye won her international fame and a medal from the king of Denmark. After that, she went to work for the U.S. Nautical Almanac Office to compute ephemeredes of the planet Venus.

When Vassar College was founded in 1865, she joined the faculty as a professor of astronomy and director of the college observatory. She became the first woman elected to the American Academy of Arts and Sciences, and founded the Association for the Advancement of Women in 1873, chairing the Committee on Women’s Work in Science until her death.

Mercury farthest east of setting sun on May 25

  • May 25, 2014

2014-may-25-mercury-jupiter-night-sky-chart
Mercury, the solar system’s innermost planet, orbits the sun inside of Earth’s orbit. Therefore, Mercury always stays close to the sun in Earth’s sky and is often lost in the sun’s glare. But Mercury reaches its greatest elongation – greatest angular distance – east of the sun on May 25, so this world can now be spotted low in the west-northeast as dusk ebbs into darkness. As always, binoculars help out with any Mercury quest.
The planet Jupiter is the first “star” to pop out after sunset. If you’re familiar with the star Regulus, you can draw an imaginary line from Regulus and past Jupiter to locate Mercury near the sunset point on the horizon. (See sky chart below.) Given a clear sky and unobstructed horizon, Mercury could be visible to the unaided eye about 60 to 90 minutes after sunset. If not, try binoculars.

Although Mercury shines more brightly than Regulus does, you might see Regulus first because it’s not as obscured by the glow of evening twilight. What is the ecliptic?

…and don’t forget the morning sky, which features the dazzling planet Venus and a thin waning crescent moon on Monday, May 26.

Setting times of the sun and Mercury in your sky

At an elongation of 23o Mercury lies far enough east of setting sun to stay out until the end of astronomical twilight (at mid-northern latitudes). By definition, astronomical twilight ends in the evening sky when the sun is 18o below the horizon. For reference, the sun’s diameter equals one-half degree, and your fist at an arm length approximates 10o.

Because Mercury is setting a maximum amount of time after sunset right now, this is your chance to catch Mercury low in the west at late dusk or nightfall. But don’t tarry when seeking this elusive yet surprisingly bright world, for Mercury – even now – follows the sun beneath the horizon around nightfall. At mid-northern latitudes, astronomical twilight ends nearly two hours after sunset, at about the same time that Mercury sets beneath the horizon.

End of nautical twilight and Mercury’s setting time in your sky

We should mention that the Northern Hemisphere enjoys the better view of this particular evening apparition of Mercury. That’s because the ecliptic – the pathway of the planets – hits the horizon at a steeper angle as the sun sets in the Northern Hemisphere sky.

What is the ecliptic?

Mercury stands higher over the horizon at sunset in Northern Hemisphere than at comparable latitudes in the Southern Hemisphere. For instance, at 40o north latitude – the latitude of Philadelphia, Pennsylvania – Mercury’s altitude at sunset is about 19o. In contrast, at 40o south latitude – the latitude of Wanganui, New Zealand – Mercury’s altitude is less than 11o at sunset.

No wonder Mercury sets more than 100 minutes after sunset at mid-northern latitudes but less than 80 minutes after sunset at mid-southern latitudes. The farther north you live, the later that Mercury sets after sunset; and the farther south you live, the sooner.

Although this evening apparition of Mercury favors the Northern Hemisphere, everyone worldwide has a reasonably good chance of catching Mercury after sunset right now. Look for Mercury above the sunset point on the horizon some 60 to 75 minutes after sunset.

Mercury might be visible to the unaided eye for another week or so, but binoculars always help out with your search for Mercury, the solar system’s innermost planet.

Is Saturn making a new moon?

  • April 16, 2014

A small icy object within the rings of Saturn might be a brand new moon in the process of being born.

saturn-new-moon

NASA’s Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn that may be a new moon, and may also provide clues to the formation of the planet’s known moons.

Images taken with Cassini’s narrow angle camera on April 15, 2013, show disturbances at the very edge of Saturn’s A ring — the outermost of the planet’s large, bright rings. One of these disturbances is an arc about 20 percent brighter than its surroundings, 750 miles (1,200 kilometers) long and 6 miles (10 kilometers) wide. Scientists also found unusual protuberances in the usually smooth profile at the ring’s edge. Scientists believe the arc and protuberances are caused by the gravitational effects of a nearby object. Details of the observations were published online today (April 14, 2014) by the journal Icarus.

The object is not expected to grow any larger, and may even be falling apart. But the process of its formation and outward movement aids in our understanding of how Saturn’s icy moons, including the cloud-wrapped Titan and ocean-holding Enceladus, may have formed in more massive rings long ago. It also provides insight into how Earth and other planets in our solar system may have formed and migrated away from our star, the sun.

“We have not seen anything like this before,” said Carl Murray of Queen Mary University of London, the report’s lead author. “We may be looking at the act of birth, where this object is just leaving the rings and heading off to be a moon in its own right.”

The object, informally named Peggy, is too small to be seen in images so far. Scientists estimate it is probably no more than about a half mile (about a kilometer) in diameter. Saturn’s icy moons range in size depending on their proximity to the planet — the farther from the planet, the larger. And many of Saturn’s moons are composed primarily of ice, as are the particles that form Saturn’s rings. Based on these facts, and other indicators, researchers recently proposed that the icy moons formed from ring particles and then moved outward, away from the planet, merging with other moons on the way.

“Witnessing the possible birth of a tiny moon is an exciting, unexpected event,” said Cassini Project Scientist Linda Spilker, of NASA’s Jet Propulsion Laboratory in Pasadena, Calif. According to Spilker, Cassini’s orbit will move closer to the outer edge of the A ring in late 2016 and provide an opportunity to study Peggy in more detail and perhaps even image it.

It is possible the process of moon formation in Saturn’s rings has ended with Peggy, as Saturn’s rings now are, in all likelihood, too depleted to make more moons. Because they may not observe this process again, Murray and his colleagues are wringing from the observations all they can learn.

“The theory holds that Saturn long ago had a much more massive ring system capable of giving birth to larger moons,” Murray said. “As the moons formed near the edge, they depleted the rings and evolved, so the ones that formed earliest are the largest and the farthest out.”

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. JPL, a division of the California Institute of Technology, manages the mission for NASA’s Science Mission Directorate in Washington.
