PIX4572996: Hertzsprung - Russell - The Hertzsprung - Russell diagram - HR diagram (Hertzsprung - Russell) 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) / Bridgeman Images

PIX4573136: Planet around the star Fomalhaut - Planet orbiting star Fomalhaut - Artist's view of the extrasolar planet Fomalhaut b, a planet with a mass close to Jupiter, orbiting the star Fomalhaut, 25 years ago - light from Earth in the constellation of the Southern Fish. Located at a distance of about four times that separating Neptune from the Sun, Fomalhaut b makes a complete orbit around its star in 872 years. This illustration shows the discovered planet, Fomalhaut b, orbiting its sun, Fomalhaut. This structure is a Saturn - like ring that astronomers say may encircle the planet. Fomalhaut also is surrounded by a ring of material. The edge of this vast disk is shown in the background as the curving cloud - like feature that appears to intersect the 200 - million year - old star. Fomalhaut b lies three billion kilometers inside the disk's inner edge. The planet completes an orbit around Fomalhaut every 872 years / Bridgeman Images

PIX4573193: Planetary system around the star HD 69830 - Planetary System Around HD 69830 - Artist's view of three planets orbiting around the star HD 69830. This planetary system is the first detects around a star similar to the Sun that contains several planets whose mass is less than that of Jupiter. It seems that this system also has an asteroid belt. Using the ultra - precise HARPS spectrograph on Eso's 3.6 - m telescope at La Silla (Chile), a team of European astronomers have discovered that a nearby star is host to three Neptune - mass planets. The innermost planet is most likely rocky, while the outermost is the first known Neptune - mass planet to reside in the habitable zone. This unique system is likely further enriched by an asteroid belt. This view portaits a point of view inside the asteroid belt, which is assumed here to lie between the two outermost planets / Bridgeman Images
PIX4573229: Exoplanetes glacees - Three worlds of ice and snow - Artist's view of extrasolar planets composed of ice. Far beyond our own solar system there are a likely billions of other planets orbiting stars like and unlike our own sun. Our sun, our Earth and moon, our solar system, represent only one of an unimaginable number of possibilities / Bridgeman Images
PIX4573262: Exoplanete Tau Bootis b - Tau Booetes b - Artist's view of the extrasolar planet Tau Bootis b view of a hypothetical satellite. Tau Bootis b is located 50 years of light from Earth in the constellation Bovier. It is a gas exoplanet about four times the mass of Jupiter, located very close to its star. The extrasolar planet Tau Booetes b reigns over the airless, baked and battered terrain of a hypothetical moon. Tau Booetes b orbits very close to Tau Booetes, a type F7V star about 50 light years from the Earth. Tau Booetes b is believed to have about four times the mass of the planet Jupiter and orbits around its sun at the astonishing pace of once every 3.3 days. Tau Booetes b is so close to its host sun that the force of the solar wind may be enough to constantly blow off the planet's outer atmosphere / Bridgeman Images
