Hubble Spots Swirls of Dust in the Flame Nebula

The Flame Nebula, also called NGC 2024, is a large star-forming region in the constellation Orion that lies about 1,400 light-years from Earth. It’s a portion of the Orion Molecular Cloud Complex, which includes such famous nebulae as the Horsehead Nebula and Orion Nebula. This image focuses on the dark, dusty heart of the nebula, where a star cluster resides, mostly hidden from view. Nearby (but not visible in this image) is the bright star Alnitak, the easternmost star in the Belt of Orion. Radiation from Alnitak ionizes the Flame Nebula’s hydrogen gas. As the gas begins to cool from its higher-energy state to a lower-energy state, it emits energy in the form of light, causing the visible glow behind the swirled wisps of dust.

Researchers have used Hubble to measure the mass of stars in the cluster as they search for brown dwarfs, a type of dim object that’s too hot and massive to be classified as a planet but also too small and cool to shine like a star.

This is a Hubble Space Telescope image of the barred spiral galaxy UGC 12158. The majestic galaxy has a pinwheel shape made up of bright blue stars wound around a yellow-white hub of central stars. The hub has a slash of stars across it, called a bar. The galaxy is tilted face-on to our view from Earth. A slightly s-shaped white line across the top is a Hubble image is of an asteroid streaking across Hubble's view. It looks dashed because the image is a combination of several exposures of the asteroid flying by like a race car.

NASA’s Near Space Network Enables PACE Climate Mission to ‘Phone Home’

The PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission has delivered its first operational data back to researchers, a feat made possible in part by innovative, data-storing technology from NASA’s Near Space Network, which introduced two key enhancements for PACE and other upcoming science missions. As a satellite orbits in space, its systems generate critical data […]

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.
