Because of the extremely special genes of the Zerg and the special "feedback" mode between the mother and child of the Zerg, the superpowers of the little buns can be partially reflected and gifted to Gao Ling.

Therefore, Gao Ling was able to survive in outer space for longer and longer - in the final analysis, it was because the little buns had awakened the bloodline of the Warcraft, and the Zerg genes were good at evolution and learning from each other's strengths, so that Gao Ling indirectly received benefits.

Although teleportation only took two or three breaths to enter the super terrestrial planet spaceport that was being developed, Gao Ling did not feel uncomfortable this time because of the sudden change in time and space.

Speaking of which, Super Warcraft now has to remove his disguise, he no longer pretends to be a cat, but after seeing Gao Ling again and holding her in his arms, his expression is a little stiff.

Gao Ling also felt a little guilty, so the two of them crossed the beautiful and spectacular reflection nebulae along the way, even if they looked at a magnificent cosmic wonder together, they didn't speak once.

A reflection nebula is a nebula that becomes bright and visible by reflecting and scattering the light of a nearby illuminating star. In 2010 it became known that HH objects are high-velocity air currents ejected from very young stars. A nebula that becomes bright and visible by reflecting and scattering the light of nearby illuminating stars. Unlike the emission line spectrum of the emission nebula, the spectrum of the reflected nebula is similar to the absorption line spectrum of the illuminated star. Reflected nebulae have illuminated stars from early B type to G and K type (see stellar spectral classification), and most of them are B1~B8 type. Reflection nebulae differ from emitting nebulae that are red in color, in that they emit light by reflecting light from nearby stars. It is blue. The luminosity of the reflected nebula is faint and weak.

Reflection nebulae, from an astronomical point of view, are simply composed of dust, clouds that simply reflect the light of nearby stars or star clusters. These neighboring stars don't have enough heat for the clouds to glow as ionized as emitting nebulae, but they do have enough brightness for dust particles to be seen by scattering light. Thus, the reflection nebula shows a spectrum of frequencies similar to that of the star that illuminates it. Scattering light in nebulae are carbon-containing particles (such as diamond dust) and other components, especially iron and nickel, which are often arranged in galactic magnetic fields, causing slight polarization of the starlight (Kaler, 1998). Harper distinguished these two types of nebulae in 1922.

Since scattering is more efficient for blue light than for red light (this is the same process as the sky appears blue and the sunset appears red). So reflection nebulae are usually blue. The blue reflective nebula reflects that the nebula itself does not emit light. Its main component is interstellar dust. They can be seen mainly because they reflect light from neighboring stars. These nebulae are usually blue because they reflect more blue light. In fact, luminous nebulae and reflective nebulae are usually inseparable, and they always stay together. We refer to them collectively as "diffuse nebulae". These nebulae are usually home to young stars.

There are about 500 of the known reflection nebulae. One of the most beautiful is the reflected nebula that surrounds the Pleiades star cluster. There is also a blue trifid nebula in the same area of the sky. Antares is a very red giant star (spectrally classified as M1). Surrounded by a large red reflective nebula.

The Pleiades reflection nebula has a different emission line spectrum than the emission nebula, and the reflection nebula's spectrum is similar to that of the illuminated star. The reflected nebulae range from early B type to G and K type, and most of them are B1-B8 type. The stars that excite and emit nebulae are all earlier than B1 type; On the other hand, there are some bright nebulae with a B1 type of illuminated star, which has a transition spectral type, i.e., both zài emission and absorption lines. Some hybrid bright nebulae have also been observed, i.e., within the same nebula, part of the table xiàn is the emission nebula, and the other part is the reflection nebula.

There is no essential difference between emission nebulae and reflection nebulae, and the different spectral signatures between them are determined by the type of illuminated star (type B1 seems to be the dividing line). In the reflected nebula, due to the low temperature of the illuminated star and the lack of strong ultraviolet radiation, the atoms in the nebula cannot be effectively excited, so there are no emission lines in the spectrum.

From the observation of the surface brightness of the reflected nebula, it is found that they have a high albedo, from which it is inferred that the particles that produce reflection in the nebula may be Xiaoice particles composed of simple molecular compounds of light elements such as hydrogen, carbon, nitrogen, and oxygen, and the particle size is about 1/4 micron. The reflected nebula is faint and easy to observe, and the reflected nebula around the Seven Sisters cluster of M45 in Taurus is a reflection nebula that can be seen with a telescope on a highly transparent and moonless night. The Orion Reflection Nebula NGC1999 a typical reflection nebula, like fog illuminated by street lamps, the gas and dust that permeate interstellar space do not emit visible light itself, but only shine by reflecting the light of nearby stars. It is located in the region of active star birth in the constellation Orion, about 1,500 light-years from Earth. This nebula is famous for the discovery of the first Herbig-Haro object right next to it. The Herbig-Haro object is a stream of gas ejected from extremely young stars. The young star V380 that illuminates the NGC1999 nebula has a surface temperature of 10,000 degrees Celsius, emits a white light, and is about 3.5 times the mass of the Sun NGC1999. In the center of the nebula, a T-shaped black cloud is quite conspicuous, this black cloud is named after the astronomer BartBok of the University of Arizona, the "Bock Sphere", which is a cloud of low-temperature gas and cosmic dust, which is so dense that it can block the light behind it. In the photo of the Harbour telescope, the Burke ball is set off by a bright nebula behind it. Astronomers believe that a new star is brewing in the center of Burke. NGC1999 was discovered by William Heschel and his sister Caroline Hesel about 200 years ago, and was listed in the 4NGC catalog in the 19th century

Reflection nebulae, which shine by reflecting light from nearby stars, are blue in color. The luminosity of the reflected nebula is faint and weak. An easier example to observe is the reflected nebula around the Seven Sisters cluster of M45 Taurus, which can be seen with a telescope on a highly transparent and moonless night, surrounded by a pale blue nebula.

Orion's Reflection Nebula In December 1999, just weeks after NASA astronauts repaired the Hubble Space Telescope, the Hubble Legacy Project team captured this photograph of the Orion Reflection NGC1999 Nebula, which resembles the fog around a street lamp, because its embedded light source illuminates the dust in the nebula; Nebulae themselves do not emit any visible light. This nebula is famous in the history of astronomy because of the first discovered HH object (Herbig?) Arrow object) is in its vicinity (the HH object happens to be not in the picture), and it is known that the HH object is a high-velocity air stream ejected by a very young star.

This reflected nebula is illuminated by a bright, recently formed star (center-left in the image), which is numbered Orion V380. The surface temperature is as high as 10,000 degrees Celsius (almost twice that of the sun) and it glows white. Its mass is estimated to be 3.5 times that of the Sun. The star is so young that it is still surrounded by the remaining primordial material that formed the star, and this is the NGC1999 reflection nebula we see. Near the center of the NGC1999 there is an unusual black jet cloud, a little lower to the right of the bright star in the picture. This dark cloud is a "bock sphere". Named after the University of Arizona astronomer BartBok. The spheroid is a very dense cloud of cold gases, molecules, dust. Blocks all light behind it. Its outline is shown against a backdrop of a reflective nebula illuminated by V380. Astronomers believe that the dust and molecular clouds in Bock's spheres will shrink under their own gravitational pull and form new stars.

The gorgeous Reflection Nebula NGC2023 located in the constellation Orion, about 1,500 light-years away. It is in close proximity to the famous Flame Nebula and the Horsehead Nebula. The entire NGC2023 Nebula is about 4 light-years wide. The Hubble Space Telescope, on the other hand, captures only a partial image of the southern part of the nebula, with a ray of light that resembles the afterglow of a sunset on Earth. Reflection and emission nebulae are often combined to form diffuse nebulae, such as the Orion Nebula.

Reflection nebulae are also often the site of star formation.

In 1922, Harper published the results of his investigation of the Bright Nebula, part of which was the luminosity of the reflected nebula. He obtained the relationship between the apparent magnitude (R) of the reflected nebula and the associated apparent magnitude of the star (m):

5log(R)=-m+k

The k here is the constant related to the sensitivity of the measuring instrument.

The Orion Nebula (M42, NGC1976) is a reflective nebula located in the constellation Orion, and a diffuse nebula located in the constellation Orion. It was discovered in 1656 by the Dutch astronomer Huygens, with a diameter of about 16 light years, an apparent magnitude of 4, and a distance of 1,500 light years from the Earth. The Orion Nebula is a huge cloud of gas dust in space that is producing new stars. Through the guò telescope, it can be seen that the shape of the Orion Nebula is like a large bird with spread wings, and its brightness is quite high, second only to the Kalina Nebula throughout the day, and it can be observed with the naked eye in areas without light pollution. The Orion Nebula is the brightest gas nebula of the day. Ancient astronomers had already discovered the Orion Nebula and named it α Orion as a star.

Some of the brightest stars in the Orion Nebula were recorded as 5th magnitude stars by early astronomers, such as Ptolemy, Tycho? Brahe and John? Valle.

Although the Orion Nebula is visible to the naked eye, there is no documentation of its existence before the advent of telescopes.

In 1610, Nicholas-Claude Fabride Peiresc discovered the Orion Nebula via the Guò telescope.

The famous astronomer Huygens also discovered the Orion Nebula in 1656.

Charles? Messier first recorded it and three of the quadruples in 1769. It was recorded in the first edition of the Messier List of Celestial Objects, published in 1774. Since it is the 42nd deep-sky object discovered by Messier, it is also known as M42.

On September 30, 1880, Henry? Draper gets his first photograph of the M42. Henry? Draper has been exposed for 15 minutes to successfully photograph the nebula next to the Orion quadrangle, and now with a wide-angle lens camera, a fixed exposure of 5 minutes can already capture the entire constellation Orion and the Orion Nebula's pink glow.

In 1993, the Hubble telescope first observed M42.

The Orion Nebula is a very young celestial body, and there are many young stars. And there are also many prestellar objects. For example, in 1966, an infrared star with a blackbody temperature of only 600 K was discovered in the Orion Nebula, which is a protostar in gravitational contraction, with a radius of 8 astronomical units and a mass of 6 M⊙. NOT FAR FROM THIS INFRARED STAR, AN INFRARED NEBULA WITH A BLACKBODY TEMPERATURE OF ONLY 70K WAS FOUND, WITH AN ANGULAR DIAMETER OF MORE THAN 30" AND A MASS OF 102~103M⊙. Later, sources of hydroxyl and water molecule radiation were discovered in the vicinity of these infrared objects. In addition, some spheroids have been found in the Orion Nebula, which have a mass of about 1M ⊙ and a temperature of about 10 K, which are also protostars in the gravitational contraction phase. X-rays from the Orion Nebula have been observed.

The Orion Nebula is part of a giant molecular cloud that covers almost the entire area of the sky outlined by the constellation Orion. Some of the densest parts of this nebula absorb visible light. It can only be observed with infrared or radio methods. These dense areas include hot spots associated with the birth of stars. There are stars in the nebula, which are only 1 million years old, and they emit intense ultraviolet radiation, which is absorbed by the gas in the nebula. and re-radiate it in the form of visible light. Thus the nebula is bright. The luminous part of a nebula is an ionization region.

The Orion Nebula is the heart of the Orion Star Society. In the vicinity of the nebula, there are many stars that form a galactic star cluster called the Orion Nebula Cluster, and the famous "Orion Quadrilateral" cluster is located in the nebula. In the Orion Nebula Cluster and the Orion Quadrilateral. There are many O-type and early-B type hot stars with surface temperatures up to tens of thousands of degrees, and the intense ultraviolet radiation emitted by them causes nebulae to be excited and produce radiation, so the spectrum of nebulae is mainly emission lines. Radio observations have revealed that the Orion Nebula leaves the Orion Nebula cluster at a speed of 8 kilometers per second.

Many of the stars in this nebula are in the formative stage, and they are surrounded by a very thick cloud of dust. Unlike visible light, infrared light penetrates the dust and matter of the universe, allowing astronomers to understand the formation of stars with the help of infrared observation equipment.

Orion Nebula, with three bright stars in a neat arrangement, another

There are also 3 small stars arranged diagonally, and you can see that the one in the middle of the 3 small stars is faintly glowing red without a telescope, and it is not a star, but a large Orion nebula.

It is a glowing gas cloud in the constellation Orion, which can be directly observed in the middle of the Orion sword. The nebula is connected to a star-forming region and is illuminated by the young stars it contains, making it spectacular in astronomical photographs. The Orion Nebula is also one of the indicators for identifying Orion.

The quadrat in the center of the nebula is one of the observation and research goals for studying the birth of stars, and the meticulousness of photographing the nebula next to it is also an object that tests the resolution and post-processing skills of astrophotography, telescopes, and post-processing.

The Orion Nebula is an X-ray source that contains some Herbig? Arrow object with a pulse source and several T-type stars in the constellation Taurus. Because of its proximity to Earth, the Orion Nebula is one of the most thoroughly studied celestial objects by humans.

Most of the stars in the Orion Nebula were formed 2 million to 3 million years ago, and their actual age is less than one thousandth of the age of the Sun and Earth. The Orion Nebula is one of the main subjects for astrophotography enthusiasts and the observatory's large telescopes. For astronomy enthusiasts, M42 is a deep-sky object worth seeing: all it takes is a small telescope or binoculars to see. The nebula is a popular subject of study for astronomers, from large ground-based telescopes to the Haber Space Telescope (HST). The Orion Nebula is also one of the main subjects for astrophotography enthusiasts and the observatory's large telescopes.

Astronomers have directly observed the protoplanetary disk, brown dwarfs, the intense and chaotic movement of gas, and the abundance of photonized stars in the vicinity of the nebula.

One can see M42 with just a pair of binoculars or small binoculars. In ideal conditions, a five-minute exposure with a camera with a wide-angle lens can capture the entire constellation Orion and the Great Orion Nebula. The meticulousness of the photograph of the nearby nebula is also an object that tests astrophotography, telescope resolution and post-processing skills.

From 2004 to 2005, scientists from the American Space Telescope Research Institute and the European Star Space Agency observed the Orion Nebula with advanced mapping cameras and other equipment on board the Hubble Space Telescope, and obtained the highest-resolution panoramic photos of the nebula. See the Orion Nebula through ordinary binoculars. It is like a firebird that spreads its wings and flies, so it also has the titles of Firebird Nebula and Flame Nebula, but it is not commonly used.

The Hubble Space Telescope has captured the clearest panoramic view of the Orion Nebula to date (as of January 11, 2006). This image not only shows the birth of a large number of stars, but also contains rare brown dwarfs. Located about 1,500 light-years from the Solar System, the Orion Nebula is the closest star birthplace in the Milky Way, containing thousands of newborn stars and star-bearing interstellar dust clouds, and has long been a "hot spot" for astronomers. From 2004 to 2005, scientists from the American Space Telescope Research Institute and the Eurostar Space Agency used advanced mapping cameras and other equipment on board the Hubble space telescope to observe the Orion Nebula, and obtained the highest-resolution panoramic photos of the nebula. Looking through ordinary binoculars, the Orion Nebula is already like a firebird with wings spreading. Therefore, it also has the title of "Firebird Nebula." but not commonly used.

In the first month of 2007, the Quadrant meteor shower kicked off the 2007 Astronomical Show. This month, the Sun moves from Sagittarius to Capricorn, and the Orion Nebula, the most spectacular constellation of winter, is admired.

Located about 1,500 light-years from the Solar System, the Orion Nebula is the birthplace of the nearest star in the Milky Way. It contains thousands of newborn stars and columnar interstellar dust clouds that give birth to stars. It has long been a hotspot for astronomers' observations.

Orion is the most spectacular constellation in the winter sky. Due to its great brightness, it is also one of the best deep-sky objects to observe in winter. The Orion Nebula, numbered M42, is an emission nebula. It is located in the middle of the Orion "Sword". The entire Orion Nebula is about 100,000 times more massive than the Sun. This is a well-known area where stars are born, and many of the "spheroids" in the nebula are protostars that are forming.

The Carina Nebula is a large bright nebula surrounded by η star on the base of the ship. The nebula is estimated to be between 6,500 and 10,000 light-years away from Earth, located on the base of the ship, and contains several O-type stars. This nebula is a huge hydrogen free zone within the Milky Way, with an apparent magnitude of up to 1.0. Although it is four times larger and brighter than the Orion Nebula, it is not as well-known because of its southerly location. The η Nebula of the Constellation of the Carina Nebula is also known as the Keyhole Nebula, the Carina Nebula, the η Kalina Nebula, or the NGC3372. It is a massive nebula within the Milky Way Centaur arm, located at the base of the ship, and contains several O-type stars. The Great Nebula is a huge bright nebula surrounded by η star in the Milky Way, one of the largest and brightest stars in the Milky Way. Although it is far away, the central region of the nebula is still bright enough to be seen by the naked eye (although it is better observed at the equator and in the Southern Hemisphere). This image of a massive Futaba explosion made up of gas and dust fog, taken by the Hubble Space Telescope, is an image of a supermassive stellar constellation η and its η nebula on its base. The η nebula of the constellation is numbered NGC3372, and it occupies a celestial region of about 3 degrees, which corresponds to a diameter of 460 light-years at an distance of 8,800 light years. Estimated to be between 6,500 and 10,000 light-years away from Earth, this nebula is a huge hydrogen free region within the Milky Way, with an apparent magnitude of up to 1.0. This nebula is a large diffuse nebula in the sky, and although it is four times larger and brighter than the Orion Nebula, it is not as well-known because of its southerly location. He was discovered by Abbé Lacaille at the Cape of Good Hope between 1751 and 1752.

In this large bright nebula there is a tiny feature that tightly surrounds the star itself η the base of the ship, and this small nebula is called the Dwarf Nebula (derived from the Latin LittleMan). It is believed to have been thrown during an explosion in 1841 and made the star the second brightest star of the day at the time.

The image uses a combination of image processing techniques (high-frequency vibration, sub-sampling, and overlapping) to enable astronomers to produce the highest-resolution images ever created with the Hubble Space Telescope. The photo reveals surprising details.

This uplifted bubble of cosmic dust has expanded to more than 8,000 light-years away, and the structure that produced it is only 10 billion miles in diameter (the diameter of our solar system). The small amount of condensed space layer produced by cosmic dust shows a strange radial streak in a transparent state that has never been seen before.

This scene was observed by Hubble in September 1995 with the No. 2 wide-angle planetary camera. The image receives red light and uses a filter close to ultraviolet light. An eight-azimuth exposure sequence is necessary to cover the subject's enormous dynamic range, as the outermost ejecta is 100,000 times more blurred than the bright central star. (To be continued.)
