The Cat's Eye Nebula | Nordic Optical Telescope

An enormous but extremely faint halo of gaseous material surrounds the Cat's Eye Nebula and is over three light-years across. Within the past years some planetary nebulae been found to have halos like this one, likely formed of material ejected during earlier active episodes in the star's evolution—most likely some 50,000 to 90,000 years ago.

This image was taken by Romano Corradi with the Nordic Optical Telescope on La Palma in the Canary Islands. The image is constructed from two narrow-band exposures showing oxygen atoms (1800 seconds, in blue) and nitrogen atoms (1800 seconds, in red).

This NASA/ESA Hubble Space Telescope image shows one of the most complex planetary nebulae ever seen, NGC 6543, nicknamed the "Cat's Eye Nebula." Hubble reveals surprisingly intricate structures including concentric gas shells, jets of high-speed gas and unusual shock-induced knots of gas. Estimated to be 1,000 years old, the nebula is a visual "fossil record" of the dynamics and late evolution of a dying star.

The Cat's Eye Nebula: Multiwavelength Data Sonification | NASA Chandra

Data sonification translates information collected by various NASA missions—such as the Chandra X-ray Observatory, Hubble Space Telescope, and Spitzer Space Telescope—into sounds.

When a star like the Sun begins to run out of helium to burn, it will blow off huge clouds of gas and dust. These outbursts can form spectacular structures such as the one seen in the Cat's Eye nebula. This image of the Cat's Eye contains both X-rays from Chandra around the center and visible light data from the Hubble Space Telescope, which show the series of bubbles expelled by the star over time. To listen to these data, there is a radar-like scan that moves clockwise emanating from the center point to produce pitch. Light that is further from the center is heard as higher pitches while brighter light is louder. The X-rays are represented by a harsher sound, while the visible light data sound smoother. The circular rings create a constant hum, interrupted by a few sounds from spokes in the data. The rising and falling pitches that can be heard are due to the radar scan passing across the shells and jets in the nebula.

The Cat's Eye Nebula | NASA's Chandra X-ray Observatory

This composite of data from NASA's Chandra X-ray Observatory and Hubble Space Telescope is a new look for NGC 6543, better known as the Cat's Eye nebula. This famous object is a so-called planetary nebula that represents a phase of stellar evolution that the Sun should experience several billion years from now. When a star like the Sun begins to run out of fuel, it becomes what is known as a red giant. In this phase, a star sheds some of its outer layers, eventually leaving behind a hot core that collapses to form a dense white dwarf star. A fast wind emanating from the hot core rams into the ejected atmosphere, pushes it outward, and creates the graceful filamentary structures seen with optical telescopes.

Chandra's X-ray data (colored in blue) of NGC 6543 shows that its central star is surrounded by a cloud of multi-million-degree gas. By comparing where the X-rays lie in relation to the structures seen in optical light by Hubble (red and purple), astronomers were able to deduce that the chemical abundances in the region of hot gas were like those in the wind from the central star and different from the outer cooler material. In the case of the Cat's Eye, material shed by the star is flying away at a speed of about 4 million miles per hour. The star itself is expected to collapse to become a white dwarf star in a few million years.

The Cat's Eye Nebula (also known as NGC 6543 and Caldwell 6) is a planetary nebula in the northern constellation of Draco, discovered by William Herschel on February 15, 1786. It was the first planetary nebula whose spectrum was investigated by the English amateur astronomer William Huggins, demonstrating that planetary nebulae were gaseous and not stellar in nature. Structurally, the Hubble Space Telescope has revealed knots, jets, bubbles and complex arcs, being illuminated by the central hot planetary nebula nucleus (PNN). It is a well-studied object that has been observed from radio to X-ray wavelengths.

A dying star has created a fantasy-like sculpture of gas and dust. In this detailed view from the NASA/European Space Agency Hubble Space Telescope, the so-called Cat's Eye Nebula, looks like the penetrating eye of the disembodied sorcerer Sauron from the film adaptation of "Lord of the Rings."

The nebula, formally catalogued NGC 6543, is every bit as inscrutable as the J.R.R. Tolkien phantom character. Although the Cat's Eye Nebula was among the first planetary nebula ever to be discovered, it is one of the most complex planetary nebulae ever seen in space. A planetary nebula forms when Sun-like stars gently eject their outer gaseous layers to form bright nebulae with amazing twisted shapes.

"Follow the LEDA" Galaxy | Hubble

"Follow the LEDA" Galaxy | Hubble

This luminescent image features multiple galaxies, perhaps most noticeably LEDA 58109, the lone galaxy in the upper right. LEDA 58109 is flanked by two further galactic objects to its lower left—an active galactic nucleus (AGN) called SDSS J162558.14+435746.4 that partially obscures the galaxy SDSS J162557.25+435743.5, which appears to poke out to the right behind the AGN. 

Galaxy classification is sometimes presented as something of a dichotomy: spiral and elliptical. However, the diversity of galaxies in this image alone highlights the complex web of galaxy classifications that exist, including galaxies that house extremely luminous AGNs at their cores, and galaxies whose shapes defy the classification of either spiral or elliptical. 

The sample of galaxies here also illustrates the wide variety of names that galaxies have: some relatively short, like LEDA 58109, and some very long and challenging to remember, such as the two galaxies to the left. This is due to the variety of cataloging systems that chart the celestial objects in the night sky. No one catalogue is exhaustive, and they cover overlapping regions of the sky, so that many galaxies belong to several different catalogues. For example, the galaxy on the right is LEDA 58109 in the LEDA galaxy database, but is also known as MCG+07-34-030 in the MCG galaxy catalogue, and SDSS J162551.50+435747.5 in the SDSS galaxy catalog—the same catalog that also lists the two galaxies to the left.

15 Benefits of International Space Station Research | NASA's Johnson Space Center

15 Benefits of International Space Station Research | NASA's Johnson Space Center

The first decade of the International Space Station was the decade of construction. The second decade moved from initial studies to fully using the capabilities of the orbiting laboratory. We have now entered the decade of results. With more than 20 years of experiments conducted on station, more breakthroughs are materializing than ever before.

An international partnership of space agencies provides and operates the elements of the International Space Station (ISS). The principals are the space agencies of the United States, Russia, Europe, Japan, and Canada. The ISS has been the most politically complex space exploration program ever undertaken.

Curiosity Rover Update for July 13, 2022: Sols 3532-3533

A Rover-Sized Boulder

Written by Lauren Edgar, Planetary Geologist at USGS Astrogeology Science Center

"Curiosity is back on the road, but some interesting boulders caught our attention and led to a short detour. The team was already planning to divert to the southwest to get some imaging of nearby cliffs, but the large boulders that have tumbled down provide a tantalizing glimpse of what’s to come. Boulders like the large one shown in the above Navcam image (now named “Ilha Novo Destino”) can help inform our understanding of the upcoming stratigraphy, so we thought it was worth a trip to this “new island destination” for the weekend."

"But first, there’s plenty of science to be done in our workspace before we get to the boulders. Today’s two-sol plan focused on DRT, MAHLI, and APXS on the bedrock right in front of the rover, including the interesting vein and fracture patterns shown in the foreground of the above Navcam image. Today we planned 3 MAHLI imaging targets and 2 APXS targets to assess the sedimentary textures and composition of bedrock and veins. We also planned ChemCam LIBS and Mastcam multispectral observations to further characterize this outcrop. Mastcam will also be used to document the field of boulders to help plan weekend activities, and ChemCam will acquire a long distance RMI mosaic to characterize the stratigraphy. The ENV theme group planned several environmental monitoring activities to search for dust devils and monitor dust and clouds in the atmosphere. On the second sol, Curiosity will drive to a parking spot right in front of these boulders to prepare for the weekend plan. Can’t wait to see this rover-sized boulder up close!"

The Bubble Nebula: Ground-based Wide View & Hubble Comparison

This graphic shows the wider context of the Bubble Nebula. The National Optical Astronomy Observatory (NOAO) image (left) by Travis Rector has been rotated and cropped to be north-up and closer to the orientation of the Hubble Space Telescope image (right). In addition to the inner bubble seen in the Hubble image, the wider view shows a large cloud complex, including two larger shells surrounding the massive star near the center.

The Bubble Nebula: Winds & Radiation from a Massive Star [3D View] | Hubble

This visualization [no audio] of the Bubble Nebula begins with a ground-based view that encompasses the glowing cloud. The high-energy light from the massive O star, BD +60°2522, is responsible for ionizing the entire region. The virtual camera flies through the foreground stars and approaches the central bubble imaged by Hubble. The massive star continuously sheds some of its outer layers in a mass-loss wind, which has blown a bubble of gas seven light-years across. 

The video's three-dimensional perspective emphasizes the extended nature of the structure and the fact that BD +60°2522 is not located at the center. The pressure inside the bubble is able to expand more rapidly in the directions away from the surrounding nebula. The computer model incorporates both scientific and artistic interpretation of the data. In particular, distances are significantly compressed.
