Yes, of course [:I], I don't know what I was thinking then [:I] Where do all these meteorites that hit the moon come from? Our own Solar System?

Yes, from our Solar System.The vast majority of meteorites are fragments of shattered asteroids.A small number of meteorites are pieces of rock from the surfaces of other planets.Meteorites might also come from comets.

How do asteroids/comets form?

Comets, asteroids, and meteors are often grouped together since they are all basically the same thing: small pieces of rock and/or ice that aren't part of a major planet.
Asteroids are made of rocky and/or iron-nickel material and most are found in an orbit between Mars and Jupiter. Comets come from two places in the Solar System: the Oort Cloud and the Kuiper Belt.

What amazes me is that folks can actually look at a meteorite and identify which planet it came from, or whether it is just space debris.

This has to be my all time favourite photo from Hubble. The so-called Pillars Of Creation where stars are being formed.

I hope you like this too Eth,



 Barnard's Loop around the Horsehead Nebula

Credit & Copyright: Drew Sullivan (Ancient Starlight)





Bigger version here



 Why is the Horsehead Nebula surrounded by a bubble? Although hard to make out, the famous Horsehead Nebula is the slight dark indentation in the bright streak just to the left of the image center. Glowing like an emission nebula, the origin of the bubble, known as Barnard's Loop, is currently unknown. Progenitor hypotheses include the winds from bright Orion stars and the supernovas of stars long gone. Barnard's Loop is too faint to be identified with the unaided eye. The nebula was discovered only in 1895 by E. E. Barnard on long duration film exposures. The above image was taken in a single specific color emitted by hydrogen to bring out detail. To the left of the Horsehead Nebula, visible as a small dark indentation, is the photogenic Flame Nebula.

nice photos. I will share in my own ideas and experienced. I am from Philippines and located in the South of the Philippines. Ever night, I can see the very light star. I know it was a planet because I learned and knows that 2009 is the planetary alignment. This year happen to me not like last year no very light star appear every night. I strongly believed it was a planet not an ordinary star or galaxy.. same photos posted here Mars light photo.

The Hubble Ultra Deep Field

I think this represents what equates to a portion of the sky the size of a pinhead !!!

Wow!! awesome post dude!!! it takes ones breath away!!!
it makes one feel tiny and humble... it seems we are not even a tiny speck of  dust!!!!

Each speck in this picture is a galaxy....each galaxy has about 100-300 BILLION Stars !!..and there's something like 100-300 BILLION Galaxies out there !!

Do you get it ?...can you even imagine such a thing ?...can you even fathom it ?




BEYOND COMPREHENSION !!

Yeah, the Hubble Deep Field image has to be one of the most important images ever produced.

The Big Bang theory is an effort to explain what happened at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. Prior to that moment there was nothing; during and after that moment there was something: our universe. The big bang theory is an effort to explain what happened during and after that moment.

According to the standard theory, our universe sprang into existence as "singularity" around 13.7 billion years ago. What is a "singularity" and where does it come from? Well, to be honest, we don't know for sure. Singularities are zones which defy our current understanding of physics. They are thought to exist at the core of "black holes." Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of infinite density are called "singularities." Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something - a singularity. Where did it come from? We don't know. Why did it appear? We don't know.

This is the picture that had such a huge effect on me I became an astronomer! I think I was about 10-12 years old at the time and just imagining the fact that each of the little bits poking out were whole solar systems forming blew my mind!

In the Heart of the Tarantula Nebula
Credit: ESA, NASA, ESO, & Danny LaCrue



BIG PICCY HERE (Makes a great desktop piccy)




In the heart of monstrous Tarantula Nebula lies huge bubbles of energetic gas, long filaments of dark dust, and unusually massive stars. In the center of this heart, is a knot of stars so dense that it was once thought to be a single star. This star cluster, labeled as R136 or NGC 2070, is visible just above the center of the above image and home to a great number of hot young stars. The energetic light from these stars continually ionizes nebula gas, while their energetic particle wind blows bubbles and defines intricate filaments. The above representative-color picture of this great LMC nebula details its tumultuous center. The Tarantula Nebula, also known as the 30 Doradus nebula, is one of the largest star-formation regions known, and has been creating unusually strong episodes of star formation every few million years.

Meteorites are classified into three basic categories: irons, stones, and stony irons. Iron meteorites, or “irons”, are actually a combination of iron, nickel, and cobalt. Iron is the predominant metal, with 5% up to 50% nickel, and a trace of cobalt.
Stone meteorites, also called “stony meteorites” or stones,are mostly believed to be material from the crust and mantle of asteroids. A few stony meteorites are thought to be from comets. Stone meteorites contain approximately 75% to 90% silicate materials, such as olivine and pyroxene.
Stony–iron meteorites, or stony–irons, are mixtures of silicates and iron–nickel in roughly equal proportions(stony-irons are rare).


How do they determine what planet a meteor came from, if that's the case?

Also, who would one contact if they had a meteor specimen they'd like to have examined/analyzed?

Is this one moving away from us? redshift?

If you're in the UK, I'd recommend the Natural History Museum, or a local university.

Did you know that there is an excellent yet powerful type of software available to explore the Universe in all its glory and formation. One of the first extraordinary insights into the Universe, available on the computer software markert, "Uniview" provides the user to travel to different planets - stars, comets, galaxies, moons and planets pin-pointed to the exact degree!

In our ever modernising world of technology, such software is uniquely different to offer students across the world interested in roaming space and appreciating the size, volume and richness of matter which is out there.
