The Weirdest Object in our Solar System?

"The dwarf planets and other objects that litter the Kuiper belt in the far reaches of our solar system are a strange bunch, but astronomers have found what they think might be the weirdest one.

Discovered on Dec. 28, 2004 (catalogued as 2003 EL61 and nicknamed "Santa" for a time), the minor planet now known as the dwarf planet Haumea, to honor its Hawaiian discovery, is as big across as Pluto and one-third of its mass, but shaped something "like a big squashed cigar," said one of the astronomers who studies the object, Mike Brown of Caltech.

From its shape to its satellites, Haumea is a strange object, but one that could shed light on the history of collisions in the solar system, as well as the early environment of the Kuiper belt, which sits out beyond the orbit of Neptune.

When astronomers first found this object, they noticed that it was getting brighter and fainter by about 25 percent every two hours. If it were round, that observation would likely mean the object rotates every two hours, an incredible rate that would rip it apart, Brown said.

Astronomers determined that it was more likely that Haumea is elongated and rotating every four hours.

"We see this thing tumbling end over end getting brighter and fainter," Brown said.

Haumea is the fastest spinning object in the solar system.

But Haumea's football shape and frantic spin aren't the only weird things about it. It also has an unusual satellite.

Several Kuiper belt objects are known to each have a satellite orbiting them, thought in many cases to be a smaller body captured by the bigger object's gravity.

But it was apparent that Haumea's satellite, Hi'iaka didn't fit that mold. "It's way too small to be one of these captured objects," Brown said. It was also made of water ice.

It turned out that Hi'iaka did fit the situation of a body hitting Haumea and scattering ice debris throughout the area.

Haumea is big enough that it differentiated, like the Earth, so that its heaviest components settled to the core and the lightest, specifically ice, stayed at the surface. So when it collided, the pieces that were spewed out were mostly pure ice, the thinking goes.""The dwarf planets and other objects that litter the Kuiper belt in the far... more

What is Redshift?

If the lines in the spectrum of the light from a star or galaxy appear at a lower frequency (shifted toward the red) than where they are observed in the spectrum of the Sun, we say this object exhibits 'positive redshift'. The accepted explanation for this effect is that the object must be moving away from us. This interpretation is drawn by analogy with the downward shift in the pitch of a train whistle as it passes through a railroad crossing and then speeds away from us. The question is: Is recessional velocity the only thing that can produce a redshift, as modern astrophysicists presume? It has become clear that the answer to that question is an emphatic NO!

But a high redshift value does not necessarily mean the object is far away. There is another, more important cause of high redshift values.

Halton C. Arp is a professional astronomer who, earlier in his career, was Edwin Hubble's assistant. He has earned the Helen B.Warner prize, the Newcomb Cleveland award and the Alexander von Humboldt Senior Scientist Award. For years he worked at the Mt. Palomar and Mt. Wilson observatories. While there, he developed his well known catalog of "Peculiar Galaxies" that are misshapen or irregular in appearance.

Arp discovered, by taking photographs through the big telescopes, that many pairs of quasars (quasi-stellar objects) which have extremely high redshift z values (and are therefore thought to be receding from us very rapidly - and thus must be located at a great distance from us) are physically associated with galaxies that have low redshift and are known to be relatively close by. Arp has photographs of many pairs of high redshift quasars that are symmetrically located on either side of what he suggests are their parent, low redshift galaxies. These pairings occur much more often than the probabilities of random placement would allow. Mainstream astrophysicists try to explain away Arp's observations of connected galaxies and quasars as being "illusions" or "coincidences of apparent location". But, the large number of physically associated quasars and low red shift galaxies that he has photographed and cataloged defies that evasion. It simply happens too often

Because of Arp's photos, the assumption that high red shift objects have to be very far away - on which the "Big Bang" theory and all of "accepted cosmology" is based - is proven to be wrong! The Big Bang theory is therefore falsified.If the lines in the spectrum of the light from a star or galaxy appear at a lower... more
