The Orion nebula, which is 24 light-years across and has a mass of 2,000 Suns, must have something special going on.The researchers suggest that these low-mass objects come from material ejected .

Although spectacular when seen through an ordinary telescope, what can be seen using visible light is only a small part of a cloud of gas in . The OIII will highlight emission nebula (like Orion Nebula, Ring, Veil, Dumbbell, etc.)

•Kant and Laplace proposed the nebular hypothesisover two centuries ago. As these stars light up, light from the nascent stellar furnaces causes this mighty gas cloud to glow . The most sensitive survey ever undertaken of the region in the Orion Nebula where new stars are forming has revealed 13 "free-floating planets" as well as . It is one of the brightest nebulae and .

The nebula is only 1,500 light-years away, making it the closest large star-forming region to Earth and giving it a relatively bright apparent magnitude of 4. It is also one of the nearest areas of active star formation to our solar system. Most scientists believe this is how the sun and planets in our solar system formed long ago. In the search for rogue planets and failed stars astronomers using the NASA/ESA Hubble Space Telescope have created a new mosaic image of the Orion Nebula.

Imposing as it is, the Orion Nebula is merely a visible "blister" on a much larger . The arm is named for the Orion Constellation, which is one of the most prominent constellations of Northern Hemisphere winter (Southern Hemisphere summer).Some of the brightest stars and most famous celestial objects of the constellation (e.g. The Space Telescope's discoveries in the Orion Nebula are a stunning confirmation of this broad brush picture. The Solar Nebula ¥The nebular theory holds that our Solar System formed out of a nebula which collapsed under its own gravity. The Orion Nebula is a massive cloud of gas and dust around 1,300 light years from Earth and is located in the constellation of Orion.

In this nebula is a bright star cluster known as the Trapezium, marked by four bright stars near the image center.

It is around 25 light years across and is the closest star forming region to Earth.

The M42 nebula is estimated to be 24 .

Nebulae are made up of dust, basic elements such as hydrogen and other ionized gases. The Solar Nebula ¥The nebular theory holds that our Solar System formed out of a nebula which collapsed under its own gravity. Although the Orion Nebula is one of the brightest nebulas, it's still much dimmer than the moon and planets.

"Death stars" in the Orion nebula have been wreaking havoc on planets, killing them off before they even form. Stars and planets form in clouds of dust and gas called nebulae. It is the brightest nebula in the sky and can be seen with the naked eye, appearing to be a blurry star in Orion's sword. Besides nebulae and interstellar dust, there are also bits of rubble as big as small moons to as small as grains of sand. The Orion Nebula, and the cloud of gas and dust of which it is a part, have also revealed to astronomers much of story of the birth of new stars and planets.

Because of its brightness and prominent location just below Orion's belt, M42 can be spotted with the naked eye, while offering an excellent peek at stellar birth for those with telescopes.

the planets in our solar system are thought to have come from a) clumps of rocky material that exist between stars b) the same cloud of gas and dust in which the sun formed c) the sun (they were flung out from the spinning sun) d) a cloud of gas in the orion nebula

The Orion Nebula. The Trapezium cluster at the heart of the Orion Nebula has recently broken out of the dark molecular cloud. I do not recommend screwing a narrow-band Nebula filter like the Ultrablock into the visual back and leaving it there.

interstellar gas cloud—the solar nebula. •A large amount of evidence now supports this idea.

If you calculate size / velocity, you can estimate how long a particular planetary nebula took to expand to its current size. As for planets, I seldom like the filtered view, and almost always prefer no filter.

As seen from Earth, the Orion nebula is a fuzzy part of the sword of the constellation Orion.
The Flame Nebula or NGC 2024 is a large star-forming region in the constellation Orion that lies about 1,400 light-years from . The UHC filter does about the same thing, though stars will show up more.

The Orion Nebula is about 20 light years from earth and 12 light years (about 71 trillion miles) in diameter. Our star, the Sun, was born in a nursery similar to the Orion Nebula about five billion years ago. The Orion constellation is one of the most brilliant. -(Nebulais the Latin word for cloud.)

R oughly 1,500 light years from Earth, the Orion Nebula gives birth to populations of new stars. It is around 25 light years across and is the closest star forming region to Earth. The Orion Nebula is a hive of star forming activity, as a result it has given us a greater understanding as to how stars are formed. The blue region on the right consists of the reflection nebulae NGC 1973, 1975 and 1977.

The circles are color-coded: red for a planet; orange for a brown dwarf; and yellow for a star. Simply look for the middle star in Orion's sword.

During their survey of the famous star .

And for astronomers, Orion is surely one of the most important constellations, as it . It is an active star forming region. The infant Sun, too, was likely wrapped in a dusty blanket that transformed .

There is radiation bursting forth in solar flares.

Hubble studied this nebula to look for protoplanetary disks, or .

About how many planets orbit an average star in this sample? The oldest stars are only a few tens of millions of years old.

Imposing as it is, the Orion Nebula is merely a visible "blister" on a much larger .

The Orion Nebula is easily visible with the naked eye as the middle star in Orion's "sword".

There is an Orion family of constellations that consists of Orion, Canis Major, Canis Minor, Lepus, and Monoceros.


Descending from the Belt is a smaller line of three stars, the Orion Nebula or known as Orion's scabbard. ¥ observational evidence ÐWe observe stars in the process of forming today.

4 - Astronomers have detected 430 planets orbiting 300 nearby stars.
