Herbig-Haro objects are formed by the collision of newly formed stars and molecular clouds of gas and dust.  When a new star slams into a dust cloud at a speed measured in hundreds of miles per second it forms narrow jets of ejected material.

Herbig-Haro 555 is located at the tip of the bok globule in IC5070 and is annotated by the small arrow at the right-center of the image.  IC5070 is an emission nebula in the constellation Cygnus at a distance of 1,600 light-years.

Hubble's newest camera eyes hotbed of star formation

A watercolour fantasyland? No. It's actually a photograph of the centre of the Swan Nebula, or M17, a hotbed of newly born stars wrapped in colourful blankets of glowing gas and cradled in an enormous cold, dark hydrogen cloud. This stunning picture was taken by the newly installed Advanced Camera for Surveys (ACS) aboard the NASA/ESA Hubble Space Telescope.

The region of the nebula shown in this picture is about 3500 times wider than our Solar System. The area also represents about 60 percent of the total view captured by ACS. The nebula resides 5500 light-years away in the constellation Sagittarius.

Like its famous cousin in Orion, the Swan Nebula is illuminated by ultraviolet radiation from young, massive stars - each about six times hotter and 30 times more massive than the Sun - located just beyond the upper right corner of the image. The powerful radiation from these stars evaporates and erodes the dense cloud of cold gas within which the stars formed. The blistered walls of the hollow cloud shine primarily in the blue, green, and red light emitted by excited atoms of hydrogen, nitrogen, oxygen, and sulphur. Particularly striking is the rose-like feature, seen to the right of centre, which glows in the red light emitted by hydrogen and sulphur.

Rings Around the Ring Nebula 


Explanation: It is a familiar sight to sky enthusiasts with even a small telescope. There is much more to the Ring Nebula (M57), however, than can be seen through asmall telescope. The easily visible central ring is about one light-year across, but this remarkably deep exposure - a collaborative effort combining data from three different large telescopes - explores the looping filaments of glowing gas extending much farther from the nebula's central star. This remarkable composite image includes narrowband hydrogen image, visible light emission, and infrared light emission. Of course, in this well-studied example of aplanetary nebula, the glowing material does not come from planets. Instead, thegaseous shroud represents outer layers expelled from a dying, sun-like star. TheRing Nebula is about 2,000 light-years away toward the musical constellation Lyra.

Young stars sculpt gas with powerful outflows

This Hubble Space Telescope view shows one of the most dynamic and intricately detailed star-forming regions in space, located 210,000 light-years away in the Small Magellanic Cloud (SMC), a satellite galaxy of our Milky Way. At the centre of the region is a brilliant star cluster called NGC 346. A dramatic structure of arched, ragged filaments with a distinct ridge surrounds the cluster.

 A torrent of radiation from the hot stars in the cluster NGC 346, at the centre of this Hubble image, eats into denser areas around it, creating a fantasy sculpture of dust and gas. The dark, intricately beaded edge of the ridge, seen in silhouette, is particularly dramatic. It contains several small dust globules that point back towards the central cluster, like windsocks caught in a gale.

Orion Complex

Orion is one of the more famous constellations, with its three belt stars, bright red-giant star Betelgeuse. When we observe Orion with the naked eye, we can see the bright Orion nebula (also known as M42) as a fuzzy patch within the sword of Orion. But the nebula we see is only the brightest region of a nebula that spans nearly the entire constellation, known as the Orion Molecular Cloud Complex.

The Orion complex is about 240 light years across and only about 1,500 light years away, so it spans a fairly large region of sky. It is a large molecular cloud containing regions of reflection nebulae and emission nebulae, as well as dark nebulae such as the Horsehead nebula.

It is also a stellar nursery. Many of the stars seen in the constellation of Orion have their origins in the Orion complex. Most prominently, the three bright belt stars (Alnitak, Alnilam, and Mintaka) were formed within the cloud. The complex is one of the most active star production regions in the sky, and because of its proximity it gives us an excellent view of the process. When we view the region in infrared, we’ve found over 2,000 protoplanetary disks, where planets are likely forming around young stars.

There’s a lot going on in the region. But when we look at it with the naked eye, we simply see a bright, easy to find constellation. You could say the region is more complex than it seems.
The constellation of Orion is easy to see in the night sky. But around it is the fainter Orion Molecular Cloud Complex.

These two images of a pillar of star birth, three light-years high, demonstrate how observations taken in visible and infrared light by the NASA/ESA Hubble Space Telescope reveal dramatically different and complementary views of an object. The pair of images demonstrates how Hubble’s new panchromatic view of the Universe shows striking differences between visible and infrared wavelengths. This turbulent cosmic pinnacle lies within a tempestuous stellar nursery called the Carina Nebula, located 7500 light-years away in the southern constellation of Carina. The images mark the 20th anniversary of Hubble’s launch and deployment into an orbit around Earth.
[Left] This visible-light view shows how scorching radiation and fast winds (streams of charged particles) from super-hot newborn stars in the nebula are shaping and compressing the pillar, causing new stars to form within it. Infant stars buried inside fire off jets of gas that can be seen streaming from towering peaks. Streamers of hot ionised gas can be seen flowing from the ridges of the structure, and wispy veils of gas and dust, illuminated by starlight, float around it.
The dense parts of the pillar are resisting being eroded by radiation. The colours in this composite image correspond to the glow of oxygen (blue), hydrogen and nitrogen (green), and sulphur (red).
[Right] This near-infrared image shows a myriad of stars behind the gaseous veil of the nebula's background wall of hydrogen, laced with dust. The foreground pillar becomes semi-transparent because infrared light from the background stars penetrates through much of the dust. A few stars inside the pillar also become visible. Representative colours are assigned to three different infrared wavelength ranges.
Hubble’s Wide Field Camera 3 observed the pillar in February/March 2010.

The Twin Jet Nebula

The Twin Jet Nebula, or PN M2-9, is a striking example of a bipolar planetary nebula. Bipolar planetary nebulae are formed when the central object is not a single star, but a binary system, Studies have shown that the nebula’s size increases with time, and measurements of this rate of increase suggest that the stellar outburst that formed the lobes occurred just 1200 years ago.

Ejection
Wednesday, August 19, 2015: Star Hen 2-427 (AKA WR 124) and surrounding nebula M1-67 are seen here by the NASA/ESA Hubble Space Telescope. Both lie in the constellation of Sagittarius, 15,000 light-years away. The bright star ejects hot clumps of gas into space at over 93,000 miles per hour (150,000 km per hour), producing the nebula. Hen 2-427 is classed as a Wolf–Rayet star, characterized by intense ejection of mass. The nebula M1-67 may be no more than 10,000 years old, quite young in astronomical terms. Researchers released a version of this image in 1998, but recently it has been re-reduced with the latest software. Image released Aug. 17, 2015.

La Nasa da una vez más una foto meramente relevante para sus adeptos, sabemos que la agencia espacial estadounidense la Nasa es sólo para uso militar solamente para ser más y más bélicos, y dan información relevante para poder seguir como institución, para poder hacer uso de los impuestos, así tener más adeptos dando información relevante, pero en realidad la Nasa es sólo para uso militar, los extrabajadores de la Nasa nos han revelado que dan información falsa una tras otra, asegura la Nasa que no existe humanidad dentro del sistema solar y que no existe platillos voladores surcan los cielos de la tierra, la Nasa asegura que no encuentra vida extraterrestre, la Nasa da información falsa una tras otra y es pura información basura así como la basura que dejan alrededor de nuestra madre tierra, la Nasa es sumamente bélicos, al haber colocado satélites con bombas atómicas y químicas, dando paso a que otras agencias espaciales hacer lo mismo, un peligro para la humanidad terrestre y hasta para el sistema solar, sabemos que la agencia espacial estadounidense la Nasa oculta todo su militarismo, nos dan pura información falsa, se burlan de la humanidad terrestre pero no de la Conciencia humana.

Multiple Generations of Stars in the Tarantula Nebula

The star cluster Hodge 301 is an old cluster. Many of its stars have already exploded as supernovae. The filaments in the upper left corner have been compressed by the explosions of these stars. Elsewhere in the picture news stars are being born.

In the most active starburst region in the local universe lies a cluster of brilliant, massive stars, known to astronomers as Hodge 301.

Hodge 301, seen in the lower right hand corner of this image, lives inside the Tarantula Nebula in our galactic neighbor, the Large Magellanic Cloud.
