In principle these molecules could provide building blocks for living organisms.Ĭarbon-rich chemicals surround a star (ESA/ISO ISOCAM R. It is a kind of shell-like structure never detected before, made mainly of large molecules with hundreds of atoms of carbon and hydrogen.

One example is the huge bubble of organic matter that Ralf Siebenmorgen of the ISO Data Centre at Villafranca, Spain, found surrounding a young star in the Chamaeleon constellation. What about life, and the carbon chemistry on which it depends? ISO saw complex carbon-rich molecules in many places of the Universe - in interstellar space in our own Galaxy, the Milky Way, and even in other galaxies. 'And we are linking it to other systems that are now in a critical evolutionary phase.' 'We are reconstructing with great detail the history of the Solar System,' said Christoffel Waelkens of the University of Leuven in Belgium. Olivine was also detected by ISO in the dusty disks surrounding young stars, which are thought to be planetary systems in formation. Comets are remnants of the raw materials that built the Solar System, and in the bright Comet Hale-Bopp ISO found the mineral olivine, one of the main constituents of the Earth's interior. For instance, ISO found clear links between stars, comets and the Earth's origin. ISO's ability to detect a whole variety of molecules was unprecedented and its results are now filling the blank pages of the cosmic cookery book.

How did the Solar System form? Why and how did life begin on the Earth? May life exist elsewhere? But knowledge of the chemistry of the Universe has been full of gaps till now. Molecules scattered in the surroundings of the stars, or found in comets and the atmospheres of planets, hoard many secrets.

The cosmic cookery book for planets and lifeĬomet Hale-Bopp and olivine signature (ESA/ISO SWS spectrum, ISOCAM image) Looking in the far-infrared region of the electromagnetic spectrum, the astronomers observed the telltale signature of absorption by trace amounts of hydrogen fluoride gas. The new observations were carried out with the Long Wavelength Spectrometer, one of four instruments on board ISO. The astronomers searched for hydrogen fluoride molecules within a giant cloud of interstellar gas located near the centre of the Milky Way galaxy. The discovery was reported in the Astrophysical Journal Letters. Although approximately one hundred different kinds of molecules have been detected in interstellar space over the past 30 years, the discovery of hydrogen fluoride marks the first time that a molecule containing fluorine has been detected in an interstellar gas cloud. Although no telescope has been able so far to image any alien planet, ISO has detected many of these thin debris disks, which astronomers believe are made of small bodies like comets.Ī team of astronomers from the United States and Germany discovered trace amounts of hydrogen fluoride gas in the near vacuum of interstellar space. When the process is over, only a thin ring of debris remains. The left-over gas and dust that swirls around many new-born stars evolves into a so-called protoplanetary disk which glows with infrared light. While other astronomers detect unseen planets by their effect on the motion of their parent stars, ISO teams see favourable circumstances for planet-making. Is the Solar System a unique pearl in the Universe, the only example of planets orbiting a star? Definitely not. Red Rectangle imaged by ISO/MPG 2.2 microns (visible light) Many young stars are ready to build planetsĪ dust disk where ISO found olivine signature. It had previously been assumed that planets can form only round new-born stars. Their results were published in Nature on 26 February 1998.

In the vicinity of the Red Rectangle, an old binary star in the Monoceros constellation, they have detected a ring of matter constituting the first stage of planet formation. Next article: Planet Formation > Planet FormationĪstronomers at the universities of Amsterdam, Louvain, Groningen and Utrecht have found proof that planets can form around old, dying stars.
