Hubble Passes 1-Billion Second Mark

Hubble was deployed from the Space Shuttle Discovery’s cargo bay on April 25, 1990, making it one-billion seconds (over 31 years) since Hubble began operating. For more than three decades, Hubble has provided us with groundbreaking scientific discoveries and iconic images of space.

Hubble’s first one-billion seconds included five astronaut servicing missions to replace and repair components of the telescope, and more than 1.5 million scientific observations and counting! We can only imagine what discoveries the next one-billion seconds will bring as new telescopes like the recently launched James Webb Space Telescope and the future Nancy Grace Roman Space Telescope build upon Hubble’s discoveries and work together with Hubble to expand our understanding of the universe.

A spiral galaxy seen directly from the side, such that its disk looks like a narrow diagonal band across the image. A band of dark dust covers the disk in the center most of the way out to the ends, and the disk glows around that. In the center of the galaxy, a whitish circle of light bulges out above and below the disk. Each end of the disk curves slightly. The background is black and mostly empty.

Artist's concept of early stages of the young star FU Orionis outburst. The star, a bright yellow sphere near the center, and its fluffy disk of gas and dust are slightly tilted, extending from the top left corner to the bottom right. The swirling disk is bright yellow close to the star and gradually transitions to dark orange moving toward the edges of the frame. The top left and right corners reveal a black, starless background.

NASA’s Chandra, Hubble Tune Into ‘Flame-Throwing’ Guitar Nebula

Normally found only in heavy metal bands or certain post-apocalyptic films, a “flame-throwing guitar” has now been spotted moving through space. Astronomers have captured movies of this extreme cosmic object using NASA’s Chandra X-ray Observatory and Hubble Space Telescope. The new movie of Chandra (red) and Palomar (blue) data helps break down what is playing […]

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.
