a real-color image of this spiral galaxy, taken as part of a large survey in the near-ultraviolet of local galaxies so as to provide a reference sample for faint blue galaxies observed with HST. Image by Windhorst, de Jong, Ponder, Burg, and Boyle.
This image was presented in November 1996 to Pope John Paul II at a meeting of the Pontifical Academy of Sciences on the formation of galaxies. The latin inscription translates as 'the beauty of nature (seen) in ultraviolet light'.

The following several images were observed with the VATT in October 2001 by Matt Nelson, Chris Corbally, Aileen O'Donoghue, and docents from Discovery Park, Safford, Arizona. The seeing conditions were 0.8 arcseconds and the field was about 6 arcseconds square. Nelson processed these near real-color images from 3-color data.

Dumbell NebulaDumbell Nebula
Like other planetary nebula, M27 is a bubble of gas that has been ejected by a star at the end of its life. The core of the star still remains in the center and makes this bubble of gas glow. M27 is estimated to be 3,500 years old and perhaps 1,000 light years away.

NGC 6781NGC 6781
This is another planetary nebula, the ejected gas bubble from a star. That central star is more easily seen than in the Dumbell Nebula. It is the slightly bluish star right in the middle of the bubble. This nebula sits in the part of the Milky Way that goes through Aquila, a summer time constellation for the northern hemisphere.

M56Ring Nebula
This planetary nebula, also known as M57, is probably the best known. Hubble Space Telescope images indicate that we are looking down the barrel, as it were, of a gun. Some barrel, for it is about 4000 light years away and 500 times the diameter of our solar system.

M56M56
This Globular Cluster is in the constellation of Lyra like the Ring Nebula. For Charles Messier, discovering it in 1779, it seemed "without stars, having little light." This modern picture from VATT shows there are in fact countless, jewel-like stars, which were all born from a common giant cloud of gas and dust. The brighter, yellower ones were more massive initially and so evolved faster into "yellow giant" stars than the fainter, bluer ones.

NGC7479NGC 7479 (visible)
A spiral galaxy, with a central bar, showing bluish knots of new-forming stars in its arms. The knots are blue from the predominance of very hot, young stars in them. Compare this image with the one to the right, taken in the near-infrared. NGC 7479 is in the constellation of Pegasus and about 105 million light years away.
ngc7479NGC 7479 (infrared)
A 10-minute exposure through a near-infrared filter (the K band) made with the Arcetri Infrared Camera (ARNICA). The scale is 0.5 arcsec/pixel and the field of view about 2 arcminutes. Taken on Oct 31, 1996, by L. Vanzi and G.P. Tozzi.
The central bar and the inner structure of this spiral galaxy are well-shown by this infrared picture.

M33 galaxyM33 Galaxy
This picture shows the core of a companion spiral galaxy to the Andromeda galaxy M31. The full galaxy spreads about eight times larger, but it is smaller than both our Milky Way galaxy and the even larger Andromeda galaxy. However, at about 3 million light years distant, it is probably the furthest object capable of being seen by the naked eye. A telescope-aided image does reward us with much detail of its stars and dark gas lanes.
This picture, taken and processed by Matt Nelson, is a composite of 13 B filter and 6 V filter images, each with 2 minute exposure time. The last image was at a zenith distance of less than 2 degrees from the zenith, a real test of tracking for an alt-azimuth telescope like VATT.

Abel Cluster 397Abell Cluster 397
This cluster of galaxies is at an average of about 360 million light years away from earth, but one can still make out the different shapes of the galaxies. In the picture is a particularly good example of a spiral galaxy edge on to us (largest galaxy in center), and another of a face-on spiral (bottom center).
This picture by Matt Nelson consists of a set of four V filter, five R filter and seven B filter images, taken over about an hour at 4 minutes each. The history of taking the images in each filter is recorded in the trail of an asteroid in the left center of the picture.

Pholus + NGC 5964Asteroid Pholus passing NGC 5964
In May 2003, Steve Tegler (NAU) and Guy Consolmagno used the VATT to observe the unusual asteroid/comet nucleus 5145 Pholus, and one night it happened to be passing by the galaxy NGC 5964.
Note that, like the picture of Abel 397 above, they took three separate images in red, green, and blue, and then combined them to make this image; but since Pholus was moving between images, it appears as a rainbow "streak" in the image. Tegler did the image processing.

NGC 3147Spiral Galaxy NGC 3147
This galaxy in Draco, showing tightly wound spiral arms around a small nucleus, was observed in April 2004 at VATT by Francesco Di Mille and Alessandro Omizzolo as part of their study of isolated Seyfert galaxies. Di Mille combined the three separate images in red (3 min.), green (5 min.), and blue (10 min.) to make this composite color picture.

NGC628NGC 628 (R-band)
A spiral galaxy at a distance of 9.7 Mpc (32 million light years). It was taken by Vatican Observatory astronomer José Funes, S.J. and Sanae Akiyama with the University of Arizona. The images, obtained at the VATT in November 2001, illustrate the H-alpha survey of star formation in the local universe. The R-band image is at left; the H-alpha image at right. The H-alpha image reveals those regions where stars are forming.

The Shape of BulgesThe Shape of Bulges
R-band images of the sample of S0-Sa galaxies observed by Michele Cappellari and José Funes with the VATT in May 1999.

Hale-BoppHale-Bopp Comet
a 300-second exposure through a near-infrared filter (the K band) made with the Arcetri Infrared Camera (ARNICA), with the scale and field of view as for NGC 7479 (scale 0.5 arcsec/pixel, field about 2 arcminutes). Taken on November 24, 1996, by L. Vanzi and F. Mannucci.
Outgassing from the surface of this very active comet has released dust grains which are shown up by the sunlight scattered from them. The sun lies to the left; i.e., the most prominent dust jets are in the direction of the sun. The Arcetri team monitored the changes in these jets from infrared pictures taken on several nights in October and November 1996.

The following three images were observed in a V (yellow-orange) filter by Richard P. Boyle and Austin Tomaney on Jan 31, 1995, They were among the images taken during the first scientific observing run at VATT, and they were taken with the Columbia University CCD camera, having an 11 arc minute field of view.

ngc2903Spiral galaxy NGC 2903
a 400-second exposure o this home for 100 billion or more stars. It is fairly similar to our own Milky Way galaxy, though ours lacks such a prominent central bar.

m3, globular clusterM3, the Globular Cluster
a 100-second exposure of a collection of stars in a ball more than 200 light years in diameter and 40,000 light years from Earth. This cluster is made up of perhaps as many as half a million stars, held together by mutual gravitational attraction since their formation some 10 billion to 15 billion years ago.

M3, Crab Nebula M1, the Crab Nebula
a 300-second exposure of the remnant of a supernova that exploded in 1054 AD. The explosion was so brilliant it was visible during the day and was recorded by observers around the world, including the Anasazi of Chaco Canyon in the ancient American Southwest, many argue. The remnant has been continually expanding since it exploded, so this image is a contemporary "snap shot" of the Crab Nebula.
