Hubble Catches a Ring of Stellar Wildfire

NGC 1614, captured here by the NASA/ESA Hubble Space Telescope, is an eccentrically shaped galaxy ablaze with activity. The galaxy resides about 200 million light-years from Earth and is nestled in the southern constellation of Eridanus (the River).

NGC 1614 is the result of an active galactic merger, which creates its peculiar appearance, including a tidal tail. The cosmic collision also drives a turbulent flow of interstellar gas from the smaller of the two galaxies involved into the nucleus of the larger one, resulting in a burst of star formation that started in the core and has slowly spread outward through the galaxy.

Owing to its turbulent past and its current appearance, astronomers classify NGC 1614 as a peculiar galaxy, a starburst galaxy, and a luminous infrared galaxy. Luminous infrared galaxies are among the most luminous objects in the local universe — and NGC 1614 is, in fact, the second most luminous galaxy within 250 million light-years.

Hundreds of overlapping objects at various distances are spread across this field. Galaxies’ colors vary. The majority appear orange, pink, and white, some are shades of orange or blue. Most galaxies appear as fuzzy ovals, but a few have distinctive spiral arms. At the very center is a tiny galaxy nicknamed Firefly Sparkle that looks like a long, angled, dotted line. Smaller companions are nearby.

Sarah Peacock Surveys Stellar Radiation to Hunt for Habitable Worlds

Knowing whether or not a planet elsewhere in the galaxy could potentially be habitable requires knowing a lot about that planet’s sun. Sarah Peacock relies on computer models to assess stars’ radiation, which can have a major influence on whether or not one of these exoplanets has breathable atmosphere.

The image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom portion and a comparatively clear upper portion. Speckled across both portions is a starfield, showing innumerable stars of many sizes. The smallest of these are small, distant, and faint points of light. The largest of these appear larger, closer, brighter, and more fully resolved with 8-point diffraction spikes. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque. The stars vary in color, the majority of which have a blue or orange hue. The cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range. Three long diffraction spikes from the top right edge of the image suggest the presence of a large star just out of view.
