A Stellar Fingerprint | Hubble

Showcased at the center of this NASA/European Space Agency Hubble Space Telescope image is an emission-line star known as IRAS 12196-6300.

Located just under 2,300 light-years from Earth, this star displays prominent emission lines, meaning that the star’s light, dispersed into a spectrum, shows up as a rainbow of colors marked with a characteristic pattern of dark and bright lines. The characteristics of these lines, when compared to the “fingerprints” left by particular atoms and molecules, can be used to reveal IRAS 12196-6300’s chemical composition.

Under 10 million years old and not yet burning hydrogen at its core, unlike the Sun, this star is still in its infancy. Further evidence of IRAS 12196-6300’s youth is provided by the presence of reflection nebulae. These hazy clouds, pictured floating above and below IRAS 12196-6300, are created when light from a star reflects off a high concentration of nearby dust, such as the dusty material still remaining from IRAS 12196-6300’s formation.

Hickson Compact Group 31: Galaxies Glow with Millions of Young Stars | Hubble

Hickson Compact Group 31: Galaxies Glow with Millions of Young Stars | Hubble


These four dwarf galaxies waited billions of years to come together, setting off a fireworks show as thousands of new star clusters come to life. The distorted galaxies are quickly producing massive, hot, young stars that are pumping out ultraviolet radiation, heating up surrounding gas clouds, and causing them to glow.

Such encounters between dwarf galaxies are normally seen billions of light-years away and therefore occurred billions of years ago. However, these galaxies, members of Hickson Compact Group 31, are relatively nearby, only 166 million light-years away.

In this composite image of the galaxy grouping, the bright, distorted object at middle, left, is actually two colliding dwarf galaxies. Myriad star clusters have formed in the streamers of debris pulled from the galaxies and at the site of their head-on collision. The cigar-shaped object above the galaxy duo is another member of the group. A bridge of star clusters connects the trio. A long rope of bright star clusters points to the fourth member of the group, at lower right. The bright object in the center is a foreground star. The image was composed from observations made by the Hubble Space Telescope's Advanced Camera for Surveys, NASA's Spitzer Space Telescope, and the Galaxy Evolution Explorer (GALEX).

Astronomers used Hubble's Advanced Camera for Surveys to resolve the youngest and brightest of star clusters, which allowed them to calculate the clusters' ages, map the star-formation history, and determine that the galaxies are starting the final stages of galaxy assembly. Hubble reveals that the brightest clusters, hefty groups each holding at least 100,000 stars, are less than 10 million years old.

Astronomers say the interacting galaxies will form a large elliptical galaxy in another billion years.

The Advanced Camera for Surveys data were taken on August 8, 2006. The principal investigator was Jane Charlton of Pennsylvania State University, University Park (USA).

The Spitzer observations were made on February 22, 2005. The principal investigator was Kelsey Johnson of the University of Virginia and the National Radio Astronomy Observatory, both in Charlottesville (USA).

The GALEX data were taken on December 27, 2004.

A Snapshot of Interacting Galaxies in Columba | Hubble

A Snapshot of Interacting Galaxies in Columba | Hubble

The two interacting galaxies making up the pair known as Arp-Madore 608-333 seem to float side by side in this image from the NASA/European Space Agency Hubble Space Telescope. Though they appear serene and unperturbed, the two are subtly warping one another through a mutual gravitational interaction that is disrupting and distorting both galaxies. This drawn-out galactic interaction was captured by Hubble’s Advanced Camera for Surveys.

The interacting galaxies in Arp-Madore 608-333 were captured as part of an effort to build up an archive of interesting targets for more detailed future study with Hubble, ground-based telescopes, and the NASA/European Space Agency (ESA)/Canadian Space Agency (CSA) James Webb Space Telescope. To build up this archive, astronomers scoured existing astronomical catalogues for a list of targets spread throughout the night sky. By so doing, they hoped to include objects that had already been identified as interesting and that would be easy for Hubble to observe no matter which direction it was pointing.

Deciding how to award Hubble observing time is a drawn-out, competitive and difficult process, and the observations are allocated so as to use every last second of Hubble time available. However, there is a small but persistent fraction of time—around 2-3%—that goes unused as Hubble turns to point at new targets. Snapshot programs, such as the one which captured Arp-Madore 608-333, exist to fill this gap and take advantage of the moments between longer observations. As well as creating beautiful images such as this, these snapshot programs enable astronomers to gather as much data as possible with Hubble.

Wide-field View of Star AG Carinae

Wide-field View of Star AG Carinae

Pictured here is the region of the sky around the star AG Carinae, which is positioned in the center of the image. The giant star is waging a tug-of-war between gravity and radiation to avoid self destruction. AG Carinae is surrounded by an expanding shell of gas and dust. The nebula is about five light-years wide, which equals the distance from here to our nearert star, Alpha Centauri.

Snapshot of a Shedding Star: AG Carinae | Hubble

Snapshot of a Shedding Star: AG Carinae | Hubble


In this Hubble image, the strikingly luminous star AG Carinae—otherwise known as HD 94910 — takes center stage. Found within the constellation of Carina in the southern sky, AG Carinae lies 20,000 light-years away, nestled in the Milky Way.

AG Carinae is classified as a Luminous Blue Variable. These rare objects are massive evolved stars that will one day become Wolf-Rayet Stars—a class of stars that are tens of thousands to several million times as luminous as the Sun. They have evolved from main sequence stars that were twenty times the mass of the Sun.

Stars like AG Carinae lose their mass at a phenomenal rate. This loss of mass is due to powerful stellar winds with speeds of up to 7 million km/hour. These powerful winds are also responsible for the shroud of material visible in this image. The winds exert enormous pressure on the clouds of interstellar material expelled by the star and force them into this shape.

Despite HD 94910’s intense luminosity, it is not visible with the naked eye as much of its output is in the ultraviolet.

This image was taken with the Wide Field and Planetary Camera 2 (WFPC2), that was installed on Hubble during the Shuttle mission STS-61 and was Hubble’s workhorse for many years. It is worth noting that the bright glare at the center of the image is not the star itself. The star is tiny at this scale and hidden within the saturated region. The white cross is also not an astronomical phenomenon but rather an effect of the telescope.
