NGC 1365: Majestic Island Universe Image Credit & Copyright: Processing - Jean-Baptiste Auroux, Data - Mike Selby

Explanation: Barred spiral galaxy NGC 1365 is truly a majestic island universe some 200,000 light-years across. Located a mere 60 million light-years away toward the faint but heated constellation Fornax, NGC 1365 is a dominant member of the well-studied Fornax Cluster of galaxies. This sharp color image shows the intense, reddish star forming regions near the ends of the galaxy's central bar and along its spiral arms. Seen in fine detail, obscuring dust lanes cut across the galaxy's bright core. At the core lies a supermassive black hole. Astronomers think NGC 1365's prominent bar plays a crucial role in the galaxy's evolution, drawing gas and dust into a star-forming maelstrom and ultimately feeding material into the central black hole.

NGC 1316: After Galaxies Collide : Astronomers turn detectives when trying to figure out the cause of startling sights like NGC 1316. Investigations indicate that NGC 1316 is an enormous elliptical galaxy that started, about 100 million years ago, to devour a smaller spiral galaxy neighbor, NGC 1317, just on the upper right. Supporting evidence includes the dark dust lanes characteristic of a spiral galaxy, and faint swirls and shells of stars and gas visible in this wide and deep image. One thing that >remains unexplained is the unusually small globular star clusters, seen as faint dots on the image. Most elliptical galaxies have more and brighter globular clusters than NGC 1316. Yet the observed globulars are too old to have been created by the recent spiral collision. One hypothesis is that these globulars survive from an even earlier galaxy that was subsumed into NGC 1316. Another surprising attribute of NGC 1316, also known as Fornax A, is its giant lobes of gas that glow brightly in radio waves. via NASA

WHAT IS THE FARTHEST THING WE CAN SEE IN SPACE??

Welcome back,

Current observations suggest that the Universe is about 13.7 billion years old. We know that light takes time to travel, so that if we observe an object that is 13 billion light years away, then that light has been traveling towards us for 13 billion years. Essentially, we are seeing that object as it appeared 13 billion years ago.

With every year that passes, our newest technology enables us to see further and further back.

The image used for this stop on our journey is the Hubble Ultra Deep Field (UDF). The UDF is one of the deepest views of the visible universe to date; certainly it was the deepest when it was originally created in in 2003-2004. There are approximately 10,000 galaxies in this view, which is a sort of "core sample" of a very narrow patch of sky near the constellation Fornax. The smallest, reddest galaxies in the image, of which there are about 100, are among the most distant known objects!

The UDF looks back approximately 13 billion years (approximately between 400 and 800 million years after the Big Bang). Galaxies that existed in that time period would be very young and very different in structure and appearance than the grand spirals we see nearby today.

In December of 2012, astronomers announced a Hubble Space Telescope discovery of seven primitive galaxies located over 13 billion light years away from us.

The results are from survey of the same patch of sky known as the Ultra Deep Field (UDF). This survey, called UDF12, used Hubble's Wide Field Camera 3 to peer deeper into space in near-infrared light than any previous Hubble observation.

Why infrared? Because the Universe is expanding; therefore the farther back we look, the faster objects are moving away from us, which shifts their light towards the red. Redshift means that light that is emitted as ultraviolet or visible light is shifted more and more to redder wavelengths.

The extreme distance of these newly discovered galaxies means their light has been traveling to us for more than 13 billion years, from a time when the Universe was less than 4% of its current age.

Their discovery, which you can read more about in the NASA feature is exciting because it might give us an idea of how abundant galaxies were close to the era when astronomers think galaxies first started forming. (Phil Plait has a good column about this discovery too.)

As of this writing it seems that one of the galaxies in this recent Hubble discovery may be a distance record breaker - it was observed 380 million years after the Big Bang, with a redshift of 11.9. This means the light from this galaxy (pictured below) left 13.3+ billion light years ago.

Just under a month ago, the current candidate was this object: a young galaxy called MACS0647-JD. It's only a tiny fraction of the size of our Milky Way - and was observed at 420 million years after the Big Bang, when the universe was 3 percent of its present age of 13.7 billion years. To spot this galaxy, astronomers used the powerful gravity from the massive galaxy cluster MACS J0647+7015 to magnify the light from the distant galaxy; this effect is called gravitational lensing

Hubble's Constant and The Expanding Universe (I) - May 13th, 1996.

"Our Universe is expanding. Distant galaxies appear to recede from us at ever-increasing speeds. What is the rate of expansion? How long has it been expanding? What will be its ultimate fate? Two groups of astronomers were searching vigorously for answers to these fundamental questions using the Hubble Space Telescope (HST). The teams had announced conflicting measurements of the Hubble constant, a number which represents the expansion rate of the Universe. Astronomer Wendy Freedman and her collaborators used pulsating stars called Cepheids to measure the distance to galaxies, like the Fornax cluster barred spiral galaxy NGC1365 shown above. The ground based photo (left) shows an inset locating the HST image (right) which Freedman and team used to identify 50 Cepheids. Their distance and velocity measurements determined Hubble's constant to be about 80 kilometers per second per megaparsec, which meant that galaxies one megaparsec (3 million light-years) distant appear to recede from us at a speed of 80 kilometers per second. Conflicting results indicating a substantially slower expansion rate (smaller Hubble constant) were being reported by astronomer Allan Sandage and collaborators. The value of Hubble's constant was the subject of a popular public debate titled "The Scale of the Universe 1996: The Value of Hubble's Constant"."

Barred spiral galaxy NGC 1365 is truly a majestic island universe. 200,000 light-years across and located 60 million light-years away toward the constellation Fornax, NGC 1365 is a dominant member of the well-studied Fornax Cluster of galaxies. This impressively sharp color image shows the intense, reddish star forming regions near the ends of the galaxy's central bar and along its spiral arms. Seen in fine detail, obscuring dust lanes cut across the galaxy's bright core. At the core lies a supermassive black hole.

An example of violence on a cosmic scale, enormous elliptical galaxy NGC 1316 lies about 75 million light-years away toward Fornax, the southern constellation of the Furnace. Investigating the startling sight, astronomers suspect the giant galaxy of colliding with smaller neighbor NGC 1317 seen just above, causing far flung loops and shells of stars. Light from their close encounter would have reached Earth some 100 million years ago. In the deep, sharp image, the central regions of NGC 1316 and NGC 1317 appear separated by over 100,000 light-years. Complex dust lanes visible within also indicate that NGC 1316 is itself the result of a merger of galaxies in the distant past. Found on the outskirts of the Fornax galaxy cluster, NGC 1316 is known as Fornax A. One of the visually brightest of the Fornax cluster galaxies it is one of the strongest and largest radio sources with radio emission extending well beyond this telescopic field-of-view, over several degrees on the sky.

The Fornax Cluster of Galaxies Image Credit & Copyright: Marcelo Rivera

Explanation: Named for the southern constellation toward which most of its galaxies can be found, the Fornax Cluster is one of the closest clusters of galaxies. About 62 million light-years away, it's over 20 times more distant than our neighboring Andromeda Galaxy, but only about 10 percent farther along than the better known and more populated Virgo Galaxy Cluster. Seen across this three degree wide field-of-view, almost every yellowish splotch on the image is an elliptical galaxy in the Fornax cluster. Elliptical galaxies NGC 1399 and NGC 1404 are the dominant, bright cluster members toward the bottom center. A standout, large barred spiral galaxy, NGC 1365, is visible on the upper right as a prominent Fornax cluster member.

the night sky is “silent” yet still playing a universal symphony orchestrated by our beautiful mysterious Creator

like instrumental music and poetry, we see and hear things in nature just as we see written words

words that when taken inside become intertwined with our own heart and thought-life (the heart is where desire is “conceived” just as speech)

with God addressing Job:

Can you bind together a cluster of twinkling stars—

the seven sisters of Pleiades who keep company in the night sky?

Can you loosen the cords of Orion’s bow?

Can you lead the stars of the Zodiac out in their proper seasons

and guide the Bear with her cubs?

Do you know the rules of the heavens,

or apportion their influence on the seasons of the earth?

The Book of Job, Chapter 38:31-33 (The Voice)

God orchestrates “signs” in the heavens even as the stars align, yet we have no need of things such as astrology or horoscopes as forms of fortune-telling which are idolatrous in nature.

Israel in the course of their History went astray time and again from God’s truth, and some still don’t yet see their Messiah in Yeshua who the writing of the Hebrew Bible (Tanakh) points to. did you know there is a point in the world’s fiction that can become idolatry when it takes all the time of the heart & mind rather than focusing on our Creator and His truth as what is most sacred and treasured inside?

And we can see the rebirth of Israel on earth as a clear sign of God restoring the Jewish people and all Gentile believers are actually “ingrafted” into the Jewish Vine and its pure “Root” of Yeshua as Messiah over all of us

from the 36th chapter of the prophet Ezekiel:

Eternal One: On the day I cleanse you from all your sins, I will bring people back into your desolate cities, and heaps of rubble will be turned into grand structures. The wasteland will be plowed and sown—a vast change from the emptiness those passing by are used to seeing. They will be amazed, saying, “This place used to be an empty wasteland. Now it’s like the garden of Eden! The cities were demolished, lying in ruins and completely abandoned. Now they are all restored, strong and full of people!” Then the nations near you will know that I, the Eternal, am the One who rebuilt and restored the ruined cities and replanted the empty wilderness. I, the Eternal One, promise to do exactly what I’ve said.

The Book of Ezekiel, Chapter 36:33-36 (The Voice)

And we see the significance of this in the heavenly city of the new Jerusalem with its foundation stones inscribed with the 12 apostles of Yeshua and the city’s 12 gates with the 12 sons of Israel (Jacob):

Heavenly Messenger: Come with me, and I will show you the bride, the wife of the Lamb.

He took me away in the Spirit and set me on top of a great, high mountain. As I waited for what I thought was a bride, he showed me the holy city, Jerusalem, descending out of heaven from God. It gleamed and shined with the glory of God; its radiance was like the most precious of jewels, like jasper, and it was as clear as crystal. It was surrounded with a wall, great and high. There were twelve gates. Assigned to each gate was a messenger, twelve in all. And on the gates were inscribed the names of the twelve tribes of Israel’s sons. On the east wall were three gates. On the north wall were three gates. On the south wall were three gates. On the west wall were three gates. And the city wall sat perfectly on twelve foundation stones, and on them were inscribed the names of the twelve emissaries of the Lamb.

The Book of Revelation, Chapter 21:9-14 (The Voice)
