This image shows a giant star-forming region in the southern sky known as the Carina Nebula and combines the light from three different filters, which traces emission from oxygen (blue), hydrogen (green), and sulfur (red). The color is also representative of the temperature in the ionized gas: blue is relatively hot and red is cooler. The picture is a composite of several exposures made in February 2000 with the Curtis Schmidt telescope at the Cerro Tololo Inter-American Observatory (CTIO) in Chile.

| About The Data | |
| Data Description | The science team studying the Eta Car light echo was led by A. Rest (STScI). This color image of a portion of the Carina Nebula was taken with the CTIO Curtis Schmidt telescope on February 25, 2000. The filter and color assignments are as follows: oxygen (blue), hydrogen (green), and sulfur (red). |

| About The Object | |
|---|---|
| Object Name | A name or catalog number that astronomers use to identify an astronomical object. |
| Object Description | The type of astronomical object. |
| R.A. Position | Right ascension – analogous to longitude – is one component of an object's position. |
| Dec. Position | Declination – analogous to latitude – is one component of an object's position. |
| Constellation | One of 88 recognized regions of the celestial sphere in which the object appears. |
| Distance | The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs. |
| Dimensions | The physical size of the object or the apparent angle it subtends on the sky. |
