You wouldn't think that the miniscule Martian atmosphere could have any kind of a noticeable effect. I know that Mars has sandstorms and even that sounds a stretch with an atmosphere of one percent of Earth's atmosphere.

I think I may be fooling myself here. Mars has one percent of Earth's atmospheric pressure. Since Mars has only a fraction of the mass of Earth, the mass of the Martian atmosphere could be considerably more than one percent

Colorful Stars Galore Inside Globular Star Cluster Omega Centauri
Hubble snapped this panoramic view of a colorful assortment of 100,000 stars residing in the crowded core of a giant star cluster.
The image reveals a small region inside the massive globular cluster Omega Centauri, which boasts nearly 10 million stars. Globular clusters, ancient swarms of stars united by gravity, are the homesteaders of our Milky Way. The stars in Omega Centauri are between 10 billion and 12 billion years old. The cluster lies about 16,000 light-years from Earth.



Probing the Tattered Remains of Supernova Remnant N132D
The wispy, glowing, magenta structures in this image are the remains of a star 10 to 15 times the mass of the Sun that we would have seen exploding as a supernova 3,000 years ago. The remnant’s fast-moving gas is plowing into the surrounding gas of the galaxy, creating a supersonic shock wave in the surrounding medium and making the material glow.
The Hubble visible-light image reveals, deep within the remnant, a crescent-shaped cloud of pink emission from hydrogen gas and soft purple wisps that correspond to regions of glowing oxygen. A dense background of colorful stars is also visible.
Probing this tattered gaseous relic, the newly installed Cosmic Origins Spectrograph (COS) aboard NASA’s Hubble Space Telescope detected pristine gas ejected by the doomed star that has not yet mixed with the gas in the interstellar medium. The supernova remnant, called N132D, resides in the Large Magellanic Cloud, a small companion galaxy of the Milky Way located 170,000 light-years away. The resulting spectrum, taken in ultraviolet light, shows glowing oxygen and carbon in the remnant.



A clash among members of a famous galaxy quintet reveals an assortment of stars across a wide color range, from young blue stars to aging red stars.
This portrait of Stephan’s Quintet, also known as Hickson Compact Group 92, was taken by the new Wide Field Camera 3. Stephan’s Quintet, as the name implies, is a group of five galaxies. The name, however, is a bit of a misnomer. Studies have shown that group member NGC 7320, at upper left, is actually a foreground galaxy about seven times closer to Earth than the rest of the group.



Probing the Last Gasps of Doomed Star Eta Carinae
The signature balloon-shaped clouds of gas blown from a pair of massive stars called Eta Carinae have tantalized astronomers for decades. Eta Carinae has a volatile temperament, prone to violent outbursts over the past 200 years.
Eta Car A is one of the most massive and most visible stars in the sky. Because of the star’s extremely high mass, it is unstable and uses its fuel very quickly, compared to other stars. Such massive stars also have a short lifetime, and we expect that Eta Carinae will explode within a million years.
Eta Carinae is 7,500 light-years away in the constellation Carina.

Hey ...Socrates the Greek - Welcome back - Good trip ..Good to hear from you again..

Yes, There's Water on the Moon | Universe Today

Water on the moon? ..I didn't think there was enough atmosphere on the moon to sustain water- Didn't evaporate ?- Wasn't absorbed?
Didn't we just bomb the moon recently ?Was it a water bomb?. I would like to believe there is water on the moon.I would like to believe we didn't put it there .But,.. It is still one of the most plausible explanations...

.Hmmm..Water on the moon?...

However ..All that aside ..Regardless how the water got there..If all the resources are there to sustain life ,and there's enough energy to get home..Well then I say ...To the moon!..

Great day to you Green Fish, good to see you here again,
As you know at the time Earth formed 4.5 billion years ago, other smaller planetary bodies were also growing. One of these hit earth late in Earth's growth process, blowing out rocky debris. A fraction of that debris went into orbit around the Earth and aggregated into the moon.
Therefore, if the origin of the moon rock is of earthian descent, then it should not be a surprise to anyone that there is hydrogen deposits on the moon,

The LCROSS spacecraft and a companion rocket stage made twin impacts in the Cabeus crater on 9 October that created a plume of material from the bottom of the crater that has not seen sunlight in billions of years. The plume travelled at a high angle beyond the rim of Cabeus and into sunlight, while an additional curtain of debris was ejected more laterally.
“We're unlocking the mysteries of our nearest neighbour and, by extension, the solar system,” said Michael Wargo, chief lunar scientist at NASA headquarters in Washington.
“The moon harbours many secrets, and LCROSS has added a new layer to our understanding.”
Scientists long have speculated about the source of significant quantities of hydrogen that have been observed at the lunar poles.
The LCROSS findings are shedding new light on the question with the discovery of water, which could be more widespread and in greater quantity than previously suspected. If the water that was formed or deposited is billions of years old, these polar cold traps could hold a key to the history and evolution of the solar system, much as an ice core sample taken on Earth reveals ancient data. In addition, water and other compounds represent potential resources that could sustain future lunar exploration.

Since the impacts, the LCROSS science team has been analysing the huge amount of data the spacecraft collected. The team concentrated on data from the satellite's spectrometers, which provide the most definitive information about the presence of water. A spectrometer helps identify the composition of materials by examining light they emit or absorb.

Thanks socrates ..I Get that much ..What I am curious about is why the water doesn't evaporate ? or absorb .?...IT 's been sitting stagnent for millions of years.?
Couldn't we have found the water with a hydrogen sensistive satallite?...

When I have more time I'm gonna have to do some more indepth research ..

Hey ..I wonder what affect the moon crashing into the earth had on our land masses?...Do you think some of our land was formed from moon rock .?

Hmmm ... So many questions about our moon partner..Time to go get some first hand knowledge... TO THE MOON!! :)




Large Hadron Collider starts circulating protons in two directions - Times Online

Got the collider runnin again .. Still so Much to learn right here about out there ...Careful...

Where is everybody?

The radio waves from earliest radio braodcasts has now balooned out to reach hundreds of starts, yet not a peep do we hear from elsewhere. Statistically I'd guess it is certain that we are inside the bubble of someone elses random radio signals. They could have started broadcasting a million years ago, after all. Why don't we hear anyone?

There out there ..Just don't like re-runs I suppose..Too far away.Perhaps they don't understand our language or more likely we don't understand theirs...Perhaps they've already been here ..Maybe there still here?....

Ever tried to talk to an insect or whale ?...

There are Many Earthly Aliens are among us..:) Panspermia Theory

Astro-Biology is great fun ..

One of First thing to look for when looking for intelligent advanced life would be organized space junk..

Could the rings around Saturn be space junk ?.:).Hmm ..What would life on other planets look like?..Would we be able to tell?...
