Thank you for supporting this wiki project
It is incredible to get some detail from a dwarf planet like Ceres from an Earth-based observatory. Nevertheless, Fabio Carvalho of Sao Carlos, Brazil, has been able to do it. He used a medium size telescope, a 10-inch Newtonian at F/6. A 5x barlow increases that value up to F/30. Hubble space telescope has also been able to catch some more details in its surface. The same happens for Keck Observatory using adaptative optics. This dwarf planet belongs to the asteroid belt.

I had not heard of him, but I looked him up and he seems to have a colelpming and successful ministry. I'll be keeping my out for him and his work . . . Thanks for the info on Pluto your comment caused me to look that up as well and it looks like you're correct: Pluto is now considered a dwarf planet that appears to orbit Neptune as part of the Kuiper belt. Thanks for the info!

Hi Bee, It has always pzzlued me why people want to fly to the moon..... Excuse the blasphemy, but I think I'd wait for the warp drive ;-) I thought for certain a theoretical physicist would appreciate the difference between embarking on a journey into the unknown, in search of discovery and simply transportation. It's begins being seated on top of what is essentially a controlled bomb, with the countdown running to zero, followed by those words . Then a few days later, , only in reverse, touching down on a foreign world having an environment for which no living creature is naturally adapted to exist. You venture out to climb down a few steps and as you first look to this new horizon you see your in the blackness of space. Some think this is something so inspiring; it's even worth risking one's life to experience.True, after the tourists move in, this sort will be looking for new trails to blaze, without much thought of who will be to follow. Yes indeed, it was one small step for a man and one giant leap for mankind, yet do you truly think this be the reason such types dare to go or it be the reason that many theoretical physicists dare to discover in their own way? Then again some prefer the Ferris wheel, while others the roller coaster ;-)Best,PhilP.S. I give thanks on this most fitting of days for those few who consider the risks be worth it.

Some might mention that they have phoots of stuff occurring about 14 billion years ago to support Edwin Hubble’s theory that there were many red-shift in the galaxies in the past. However, there are two possibilities that many red shifts that have appeared about 14 billion light years might not give the proof that this universe could be expanding:a)There could be a possibility that the universe itself is not expanding. The original size of the universe could be so huge that it might take more than a few trillion light years for galaxies to travel pass from one end of the universe to another. As the size of the universe might be very huge so much so it would take more than a few trillion years for galaxies could be very huge, it turns up that the galaxies would take about 14 billion years to travel and yet they have not yet reach nearly the end of the galaxies in order to make a turn for their return in advancing towards us. As a result, there shows more red-shifts than blue currently. Or in other words, there would be a time in which there could be more blue shifts than red and it should be at more than a number of billions of light years later in which most of the galaxies have completed their half round of travelling in turning to us for advancing.b)There could be a possibility that the universe could be advancing as supported by Edwin Hubble.c)There could be a possibility that the universe could be lasted until infinity. If there is no boundary or space limit for this universe, many red-shifts that have discovered in the past would not give us the information that the universe could be expanding due to our universe could be lasted until infinity and there is no space limit at all.As there are two out of three possibilities that could not come to the conclusion that many red shifts in the galaxies that had been discovered by Edwin Hubble could come to the conclusion that this galaxies could be expanding, to jump into the conclusion that the universe is expanding is rather speculative.Some might comment that we could compute the size of the universe in miles from the age dimension to conclude that the size of the universe could be measured. However, by tracing the years backward in which red shifts have been advancing would not tell the size of the universe since it only could tell the number of years from now to then. It could not tell whether there could be size from the galaxies and that is beyond. For instance, if the universe could be lasted to infinity, the method that has been adopted to compute the size of universe would not turn up to be accurate.

I really wish there were more artclies like this on the web.
