Interesting information has been gathered from some recent images taken by The Spitzer Space Telescope. While the search for details about what is happening in the galaxy, one focus was geared toward the star labeled as Eta Corvi. It seems that it could be experiencing a similar setting as what occurred within our solar system, during it’s beginnnings.
Located within the constellation Corvus, Eta Corvi is one of eleven stars within that group which is visible from Earth. This star is the sixth brightest of this particular bunch, classified as F-type main sequence. These stars range between 1 and 1.5 times the size of The Sun, and they are slightly hotter. Eta Corvi is a main sequence, or dwarf star.
Recent images taken by Spitzer Space Telescope have shown where Eta Corvi has been under seige by a comet storm. The comets are being pulled into the star by it’s gravity, and they are being incenerated. Yet, these comets are crashing into any planets that could be orbiting Eta Corvi, also. This is interesting because of the potential outcome that could occur.
It is widely believed, understood, that cometary bombardment to early Earth delivered the elements and materials necessary for the intial formations of life. What is happening at Eta Corvi is comets have been identified within the inner orbital region of this star, and these comets could be impacting any planets that are within nearby orbits. That sparks interest because of the possibilities that could occur due to such collisions. The comets around Eta Corvi contain traces of ice, organic materials, and water, all of which are needed to initiate what may develop into something alive!
A widely accepted theory is that cometary impact with Earth during the early formation of our world and solar system brought the necessary elements to our planet. These are the elements that eventually would be needed to initiate the start of life. This star is estimated to be thirty percent the age of The Sun. It is forty percent as massive as our star, with a debris disk rotating aroud it.
The disk contains materials that amount to sixty percent the mass of The Moon in orbit of it. These materials mainly are comets, which are believed to have the potential to deliver life-producing elements to the scene. The comets may collide with any forming inner planets around Eta Corvi, possibly jumpstarting the processes that could begin life!
Discussions range back and forth about when life began to form on Earth. A currently accepted belief is that it started nearly 3.4 billion years ago. That would mean that ample time remains for any planets to form around Eta Corvi, letting the materials settle, then begin to breakdown into the proper, life-producing elements that would be needed to allow for the formation of living things!
Eta Corvi is roughly 59.4 light years, or roughly 349,190,347,167,130 miles away! Yes, that is trillion; not nearby! The star is situated within what we see as within a grouping of constellations that include Centaurus, Orion, and Ursa Major.

As studies of outer space are continuing, possibly increasing, some current researchers have encountered images of a solar system that is similar to our own solar system! That does seem to be exciting! I am reading through the details to find out just how much like our nook of space this particular solar system actually is presented.
The system is situated in orbit of the star Kepler-30. This is roughly 10,000 light years away from our system (no, NOT nearby….). The star itself poses intrigue because it is so similar to The Sun. We have observed, so far, that three planets are in orbit of the star.
The planets have been labeled as Kepler 30b, Kepler 30c, and Kepler 30d. Each of these worlds is larger than Earth. Kepler 30b is estimated to be 0.33 times the radius of Jupiter, and 3.7 times the radius of Earth. 30c is 1.28 times the radius of Jupiter, and it is 14.4 times the radius of Earth. 30d is .95 times the radius of Jupiter and 10.7 times the radius of Earth.
These planets are not classified as hot Jupiters! Worlds classified as such orbit their host stars at extremely rapid rates, and they are situated extremely close to the stars. Hot Jupiters are referred to as roasters because of their extreme proximity to their stars. Whereas our Jupiter fluctuates between 460,000,00 miles and 507,000,000 miles from The Sun, these worlds are squeezed within orbits of Kepler 30 at roughly the distances equivalent to the space between The Sun and Mars!
As far as scientists are aware, this is a three-planet system. It would be an unusual find to recognize that additional planets orbit at extended distances from this star, beyond those that have been located, currently. Imagine if those worlds would be Earth-like, perhaps, due to their being just far enough away from Kepler-30 to develop life-supporting atmospheres and surfaces? The gas giants within the inner orbits, and the terrestrial worlds situated outside. Hmph…..

I was doing some more studying of astronomy topics, while watching a related television program. How the Universe Works is on right now, with this episode entitled as Planets From Hell! I got caught up in listening to the details about one world that seems to have been sparking the interest of astronomy and extraterrestrial researchers for many years. The Science Channel is continuing to spark interest in what exists beyond what we know about our universe, and the possibilities of all that could be out there, beyond what we think that we know.
Details were given about an extrasolar planet that has been entitled COROT-7b. It orbits the star COROT-7, which is found in what we have labeled as The Monoceros Constellation. This constellation is not easily observable, though it has been recognized to contain stars that include V838 Monocerotis, along with the binary systems called Plaskett’s Star and Epsilon Monocerotis. Corot-7b has been calculated to be 480 light years away from us!
This planet is being described as Earth-like. However, it is not too much like Mom, as Corot-7b sits on top of it’s host star at a distance that is sixty times closer than Earth is to The Sun. That acute proximity makes Corot-7b situated within a roasting, oven-like position. The daylight temperature of the world is estimated to average near to 3,600º Fahrenheit!
As Corot-7b is so close to Corot-7, it is believed that the day side of the planet is molten lava. One studying scientist believes that this planet could have been larger, yet it was reduced in size because the hear of it’s star boiled off much of the planet! An interaction between this planet and it’s star is being revealed through what is called tidal migration. Corot-7b loses mass due to the heat of Corot-7. Plus, the gravitational interaction between the planet and the star causes tidal migration, which increases solar tides of Corot-7, while slowing the orbital speed of Corot-7b.
Again, something interesting I found while doing studies of recent online astonomy postings. It is extremely fascinating to recongize that all of that is out there, and there is so much more that we do not know about! One day, maybe even sooner than we think, we will be able to venture into further areas of The Milky Way, studying new objects, and boldy going where no one has gone before!

Yes, they found a hot one!
Yet another alluring announcement has been made, regarding revelations of what is being seen through studies of outer space. Exoplanets are seeming to be discovered regularly, and one of the latest finds is sparking interest because of it’s size. It has not been often that small planets outside of the solar system are spotted!
This world is recognized as being two-thirds as large as our Earth. Titled UCF-1.01, this planet is situated thirty-three light years from our world. It orbits a red dwarf star, GJ 436 (Gliese 436). Scientists working with Spitzer Space Telescope were able to locate this world through observations made of that area of our galaxy.
UCF 1.01, was found while astronomers at The University of Central Florida were observing the exoplanet GJ 436b with The Spitzer Space Telescope. The planets both belong to the same solar system. It was stumbled upon when the researchers were reviewing Gliese 436, getting information about the levels of carbon monoxide and methane on that extrasolar planet.
Reviews of UCF 1.01 show that it is a rocky planet, seemingly similar to Mars. This world is roughly thirty-three light years away from us. It is not likely that this world can support life, as it orbits GJ 436 at a distance that is closer to that star than Mercury is to The Sun! The heat is far too extreme, and the planet is covered in piping-hot magma!
UCF-1.01 rushes around GJ 436 at a rate of once every 1.4 Earth-length days. It is so close to it’s host star that it’s surface temperature is estimated to be near to an average of 1,000 degrees, Fahrenheit! It can not support an atmosphere because of this close range to GJ 436. Yet, additonal observations are occurring currently, to verify the existence of the neighbor world to UCF-1.01, currently being dubbed UCF 1.02!

Reading about the discoveries and the work of astronomers continues to be fascinating! A recent posting has given information about the discovery of a spiral galaxy which is supposed to be the oldest spiral galaxy that has been discovered, thus far! Telescopic views and studies have identified this particular galaxy as being around 10.7 billion years old!
The universe itself is estimated to be 13.7 billion years old, give or take a couple of billion. Scientists have reached this conclusion through studies of images captured by telescopic viewings, especially through the use of The Hubble Space Telescope. The Hubble constant is used also, where researchers factor in things like the recognized amounts of matter and dark energy, and the levels of density with these items of the universe.
The galaxy has been labeled as BX442. The discovery of this ancient galaxy puts a drastic level of pressure to the currently recognized ideas about how the age of the universe. It’s presence as a completely in-tact structure, having a full spiral shape that can be easily identified, indicates that more time must have been available for this galaxy to reach a stable form. Astonomers did not believe that galaxies were fully-shaped and indentifiable at such an ancient point of time.
I had read somewhere that our Milky Way is supposed to be a middle-aged galaxy. Yet, with the current estimates of it being around 13.6 billion years old, that would make our home galaxy pretty ancient! It would have to have begun forming shortly after The Big Bang. I will need to review more details, to work out the facts about ages of the universe, and of our galaxy.
The observations and recordings of beryllium that are used to estimate the age of the universe. This element is found within the oldest stars of the galaxy. It was formed as cosmic rays within the young universe interacted with, collided with heavier elements that were present. The isotope Beryllium-9, in particular, was formed through this method, and this element is being identified in studies of older stars that can provide information about the age of the universe.
It is all pretty interesting! As an actual lamen, in regard to how all of this astronomy stuff works, I was looking at some of the recent online postings, while trying to make sense of it all. I will likely proceed to read other related sites that give information about the age of the universe, and how things like stars first began to take shape. It is fascinating to recognize how long that all of what is known is supposed to have existed!

Aside: I got caught up, listening to the television behind me, and hearing the latest levels of stupidity flying out of Rush Limbaugh‘s mouth! He is claiming that Bane, the character from the Batman series, and featured in this latest movie release, is a planned slam at Mitt Romney! Limbaugh has said that Bane (spelled B-A-N-E) is a slam at a business venture that Romney has worked with, called Bain (B-A-I-N). Nevermind that this D.C. Comics character first appeared in Batman stories around 1993; not new at all!
