IRON AND ICE
NASA's Hubble: Galaxies, Comets, and Stars! Oh My!
by Staff Writers
Baltimore MD (SPX) Jul 26, 2013


The images were taken with the Wide Field Camera 3 on April 30, 2013.

Approaching the sun, Comet ISON floats against a seemingly infinite backdrop of numerous galaxies and a handful of foreground stars.

The icy visitor, with its long gossamer tail, appears to be swimming like a tadpole through a deep pond of celestial wonders.

In reality, the comet is much, much closer.

The nearest star to the sun is over 60,000 times farther away, and the nearest large galaxy to the Milky Way is over thirty billion times more distant.

These vast dimensions are lost in this deep space Hubble exposure that visually combines our view of the universe from the very nearby to the extraordinarily far away.

In this composite image, background stars and galaxies were separately photographed in red and yellow-green light.

Because the comet moved between exposures relative to the background objects, its appearance was blurred.

The blurred comet photo was replaced with a single, black-and-white exposure.

The images were taken with the Wide Field Camera 3 on April 30, 2013.

IRON AND ICE
NASA Comet ISON Observing Campaign
Pasadena CA (JPL) Jul 23, 2013
In 1680, Kirch's comet lit up the nighttime skies, and was even briefly visible in broad daylight. With a remarkably similar orbit to that of Comet ISON, can we expect a similar show come November? This week we chose not to highlight Comet ISON, but instead a completely different comet: C/1680 V1 (Kirch). Are we already out of ideas, and bored with Comet ISON? Of course not. Read on...
