Starship Asterisk*

Inside the head of this interstellar monster is a star that is slowly destroying it. The monster, on the right, is actually an inanimate pillar of gas and dust that measures over a light year in length. The star, not itself visible through the opaque dust, is bursting out partly by ejecting energetic beams of particles. Similar epic battles are being waged all over the star-forming Carina Nebula. The stars will win in the end, destroying their pillars of creation over the next 100,000 years, and resulting in a new open cluster of stars.

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, some 7500 light-years away in the southern constellation of Carina. The images mark the 20th anniversary of Hubble’s launch and deployment into 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 much of the dust. A few stars inside the pillar also become visible. Representative colours are assigned to three different infrared wavelength ranges.

<<The first Herbig–Haro object was observed in the late 19th century by Burnham, when he looked at the star T Tauri with the 36-inch (910 mm) refracting telescope at Lick Observatory and noted a small patch of nebulosity nearby. However, it was catalogued merely as an emission nebula, later becoming known as Burnham's Nebula, and was not recognised as a distinct class of object. However, T Tauri was found to be a very young and variable star, and is the prototype of the class of similar objects known as T Tauri stars which have yet to reach a state of hydrostatic equilibrium between gravitational collapse and energy generation through nuclear fusion at their centres.

Fifty years after Burnham's discovery, several similar nebulae were discovered which were so small as to be almost star-like in appearance. Both Haro and Herbig made independent observations of several of these objects during the 1940s. Herbig also looked at Burnham's Nebula and found that it displayed an unusual electromagnetic spectrum, with prominent emission lines of hydrogen, sulfur and oxygen. Haro found that all the objects of this type were invisible in infrared light.

Following their independent discoveries, Herbig and Haro met at an astronomy conference in Tucson, Arizona. Herbig had initially paid little attention to the objects he had discovered, being primarily concerned with the nearby stars, but on hearing Haro's findings he carried out more detailed studies of them. The [Armenian] astronomer Viktor Ambartsumian gave the objects their name, and based on their occurrence near young stars (a few hundred thousand years old), suggested that they might represent an early stage in the formation of T Tauri stars.>>

<<Viktor Ambartsumian was born to an Armenian family in Tbilisi in 1908. His father was the philologist and writer Hamazasp Amabartsumian, the translator of Homer’s Iliad into Armenian. In 1926 Victor published his first scientific article, devoted to sun jets. In 1939–1941 Amabartsumian was the director of the Leningrad University Observatory. The scientific laboratories of the University were evacuated in 1941 to remote Elabuga (Tatarstan) where Ambartsumian spent four years directing the work of the refugee laboratories. V. A. Amabartsumian died in August 1996 in Byurakan and is buried next to the Grand Telescope Tower.>>
