Flying Star Zeta Ophiuchi - Runaway Star Zeta Ophiuchi - The blue star near the center of the image is Zeta Ophiuchi, a very massive star moving at 24 km per second. It is a “” fleeing star”, a star ejected by the explosion of his companion star. In this infrared image obtained by the WISE (Wide - field Infrared Survey Explorer) satellite, the interstellar dust traversed by the star appears, as well as an arc-shaped shock wave caused by the powerful stellar winds that the star breaks. The blue star near the center of this image is Zeta Ophiuchi. When seen in visible light it appears as a relatively dim red star surrounded by other dim stars and no dust. However, in this infrared image taken with Nasa's Wide - field Infrared Survey Explorer, or WISE, a completely different view emerges. Zeta Ophiuchi is actually a very massive, hot, bright blue star plowing its way through a large cloud of interstellar dust and gas. Astronomers theorize that this stellar juggernaut was likely once part

Hertzsprung - Russell - The Hertzsprung - Russell diagram - Hertzsprung - Russell (HR) diagram displaying stars according to their surface temperature and luminosite. The Hertzsprung - Russell diagram is named after the Danish astronomer Einar Hertzsprung (1873 - 1967) and the American astronomer Henry Norris Russell (1877 - 1957). At the beginning of the 20th century they independently noticed that red stars come in very different sizes, pioneering subsequent studies of stellar parameters (e.g., temperature, size and mass). In its basic version, this diagram plots stellar temperature (or colour) against brightness (or magnitude) and is therefore also referred to as the “” colour - magnitude diagram””. The position of a particular star in the diagram also provides information about its evolutionary stage (and age)

The Hertzsprung - Russell diagram is named after the Danish astronomer Einar Hertzsprung (1873 - 1967) and the American astronomer Henry Norris Russell (1877 - 1957). At the beginning of the 20th century they independently noticed that red stars come in very different sizes, pioneering subsequent studies of stellar parameters (e.g., temperature, size and mass). In its basic version, this diagram plots stellar temperature (or colour) against brightness (or magnitude) and is therefore also referred to as the “” colour - magnitude diagram””. The position of a particular star in the diagram also provides information about its evolutionary stage (and age)

Center of the Trifid Nebula (M20) - Center of the Trifid Nebula - The Trifid Nebula (M20) is located between 5000 and 10,000 years - light of the Earth in the constellation of Sagittarius. This image obtained by the Hubble space telescope shows the center of this nebula. A group of bright stars is visible in the center of the image near the dark bands of interstellar dust. These stars are young, blue, massive and extremely hot stars; they are O-type stars and the radiation they emit influence the evolution and structure of the nebula. Trifid Nebula, also known as Messier 20 and NGC 6514, lies within our own Milky Way Galaxy between 5000 and 10 000 light - years from Earth, in the constellation Sagittarius. This image from the Hubble Space Telescope offers a close - up view of the center of the Trifid Nebula, near the intersection of the dust bands, where a group of recently formed, massive, bright stars is easily visible.

Bok's cells in NGC 281 (Cassiopee) - Bok globules in NGC 281 - View of a detail of the nebula NGC 281 in Cassiopee center on Bok's Globules. A Bok's blood cell is a dark interstellar cloud of gases and dust that absorb light. If it condenses enough, it gives birth to new stars. Near these blood cells shine blue stars; they belong to the young cluster of stars IC 1590. Image obtained by the Hubble Space Telescope in October 2005. These opaque, dark knots of gas and dust are called “” Bok globules,””” and they are absorbing light in the center of the nearby emission nebula and star - forming region. Bok hypothesized that giant molecular clouds, on the order of hundreds of light - years in size, can become perturbed and form small pockets where the dust and gas are highly concentrated. These small pockets become gravitationally bound and accumulate dust and gas from the surrounding area. If they can capture enough mass, they have the potential of creating stars in their cores; however, no

Blue stragglers in cluster 47 Toucan - Blue stragglers in globular cluster 47 Tucanae - This image obtained by the Hubble space telescope shows a detail of the 47 Toucan cluster near its center (the field is indicated on the left image taken from the ground). The yellow circles on the right image indicate the position of stars identified by the telescope as blue trainers. Because of the high density of stars within a globular cluster, a collision between two stars sometimes occurs, merging into a single young, bright and warm star called a blue straggler. The core of globular cluster 47 Tucanae is home to many blue stragglers, rejuvenated stars that glow with the blue light of young stars. A ground - based telescope image (on the left) shows the entire crowded core of 47 Tucanae, located 15,000 light - years away in the constellation Tucana. Peering into the heart of the globular cluster's bright core, the Hubble Space Telescope's Wide Field and Planetary Camera 2 separated the dense c

M8 has at least 60 giant B stars, 3 to 4 times more than the Orion nebula. M8 is an amazing stellar nursery. Hot young stars that formed out of the hydrogen gas in the nebula cause it to glow in the light of ionized hydrogen at the hydrogen - alpha wavelength of 656nm. The Lagoon Nebula gets its name from the distinctive dark lane that runs through the heart of the nebula, just to the west of open cluster NGC 6530.

Constellation of the Great Dog - Constellation of Canis Major - Sirius, the bright star on this image is the brightest star in the sky. Canis Major (the Greater Dog) is one of two dogs accompanying Orion the hunter across the sky. The other is Canis Minor. The constellation figure is ancient, and was one of 48 constellations mentioned by Ptolemy (83 - 161 AD), no doubt reflecting earlier ideas. The modern stick figure joining the brightest stars (above) certainly has a very doggy appearance. The brightest star in the sky is here, Sirius, the Dog Star, so called because its emanations were thought to affect dogs in the heat of summer, the 'Dog Days' when the star is in the same part of the sky as the Sun. Sirius is bright because it is only 8.6 light years from the Sun and it is in any case it is an intrinsically bright star, 25 times more luminous than the Sun
