James Webb snaps an image of the famous and beautiful Crab Nebula

Located 6,500 light-years away, the Crab Nebula is famous among astronomers for its elaborate and beautiful structure. A new image from the James Webb Space Telescope shows off the gorgeous nebula as seen in the infrared wavelength, highlighting the filaments of dust that create its cage-like shape.

The nebula is a supernova remnant, the result of a massive star that exploded at the end of its life centuries ago. The supernova was observed on Earth in 1054 CE, and since then astronomers have watched the nebula that resulted from that explosion grow and change.

NASA’s James Webb Space Telescope has gazed at the Crab Nebula in the search for answers about the supernova remnant’s origins. Webb’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) have revealed new details in infrared light.

The nebula has previously been imaged by other telescopes such as the Hubble Space Telescope which looks primarily in the optical wavelength and, more recently, NASA’s Imaging X-ray Polarimetry Explorer observatory which looks in the X-ray wavelength. These results have been combined into a previous image showing the nebula in optical, infrared, and X-ray.

The new Webb image, however, shows different aspects of the object. Using its NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) instruments, Webb can see the structures of gas filaments, which are shown in red and orange, as well as the regions of dust that appear as the fluffy yellow, white, and green areas. Another aspect picked up in the infrared image is a type of radiation called synchrotron radiation, created by a rotating neutron star with a strong magnetic field, which is shown as the white milky substance in the interior of the nebula.

The nebula is being studied to learn about how it formed from the supernova event, which threw out clouds of material when the star exploded.

“Webb’s sensitivity and spatial resolution allow us to accurately determine the composition of the ejected material, particularly the content of iron and nickel, which may reveal what type of explosion produced the Crab Nebula,” said lead researcher Tea Temim of Princeton University in a statement.

There will be yet more data about the Crab Nebula coming soon, as Hubble has also recently re-imaged the object for the first time since it took its original observations in 1999 and 2000.

James Webb captures a unique view of Uranus’s ring system
This image of Uranus from NIRCam (Near-Infrared Camera) on NASA’s James Webb Space Telescope shows the planet and its rings in new clarity. The Webb image exquisitely captures Uranus’s seasonal north polar cap, including the bright, white, inner cap and the dark lane in the bottom of the polar cap. Uranus’ dim inner and outer rings are also visible in this image, including the elusive Zeta ring—the extremely faint and diffuse ring closest to the planet.

A festive new image from the James Webb Space Telescope has been released, showing the stunning rings of Uranus. Although these rings are hard to see in the visible light wavelength -- which is why you probably don't think of Uranus as having rings like Saturn -- these rings shine out brightly in the infrared wavelength that Webb's instruments operate in.

The image was taken using Webb's NIRCam instrument and shows the rings in even more detail than a previous Webb image of Uranus, which was released earlier this year.

James Webb spots tiniest known brown dwarf in stunning star cluster
The central portion of the star cluster IC 348. Astronomers combed the cluster in search of tiny, free-floating brown dwarfs.

A new image from the James Webb Space Telescope shows a stunning view of a star cluster that contains some of the smallest brown dwarfs ever identified. A brown dwarf, also sometimes known as a failed star, is an object halfway between a star and a planet -- too big to be a planet but not large enough to sustain the nuclear fusion that defines a star.

It may sound surprising, but the definition of when something stops being a planet and starts being a star is, in fact, a little unclear. Brown dwarfs differ from planets in that they form like stars do, collapsing due to gravity, but they don't sustain fusion, and their size can be comparable to large planets. Researchers study brown dwarfs to learn about what makes the difference between these two classes of objects.
