Webb depicts staggering structure in 19 nearby spiral galaxies (Video)
If you follow each of the galaxy’s clearly defined arms, which are brimming with stars, to their centres, there may be old star clusters and – sometimes – active supermassive black holes. Only the James Webb Space Telescope can deliver highly detailed scenes of nearby galaxies in a combination of near- and mid-infrared light – […]
Webb Rings in the Holidays With the Ringed Planet Uranus
With its exquisite sensitivity, Webb captured Uranus’ dim inner and outer rings, including the elusive Zeta ring—the extremely faint and diffuse ring closest to the planet. It also imaged many of the planet’s 27 known moons, even seeing some small moons within the rings. In visible wavelengths, Uranus appeared as a placid, solid blue ball. […]
Webb, Hubble Combine to Create Most Colourful View of Universe (Video)
The result: a vivid landscape of galaxies along with more than a dozen newly found time-varying objects This panchromatic view of galaxy cluster MACS0416 was created by combining infrared observations from the NASA/ESA/CSA James Webb Space Telescope with visible-light data from the NASA/ESA Hubble Space Telescope. To make the image, in general the shortest wavelengths […]
NASA’s Webb Snaps Supersonic Outflow of Young Star
Herbig-Haro (HH) objects are luminous regions surrounding newborn stars, formed when stellar winds or jets of gas spewing from these newborn stars form shock waves colliding with nearby gas and dust at high speeds. This image of HH 211 from NASA’s James Webb Space Telescope reveals an outflow from a Class 0 protostar, an infantile […]
Webb Reveals Details Never Before Seen in Cassiopeia A
The explosion of a star is a dramatic event, but the remains the star leaves behind can be even more dramatic. A new mid-infrared image from NASA’s James Webb Space Telescope provides one stunning example. It shows the supernova remnant Cassiopeia A (Cas A), created by a stellar explosion 340 years ago from Earth’s perspective. […]
Webb Shows Stunning Ringed World in New Image of Uranus
The seventh planet from the Sun, Uranus is unique: it rotates on its side, at a nearly 90-degree angle from the plane of its orbit. This causes extreme seasons since the planet’s poles experience many years of constant sunlight followed by an equal number of years of complete darkness. (Uranus takes 84 years to orbit […]
Webb Captures Rarely Seen Prelude to A Supernova
The rare sight of a Wolf-Rayet star — among the most luminous, most massive, and most briefly-detectable stars known — was one of the first observations made by the NASA/ESA/CSA James Webb Space Telescope (Webb). Webb shows the star WR 124 in unprecedented detail with its powerful infrared instruments. The star is 15 000 light-years […]
Webb Portrays the Pillars of Creation, Full of Stars
Video on how NASA’s James Webb Space Telescope, ESA and CSA have captured a lush and highly detailed landscape: the iconic Pillars of Creation; in this episode of Space Sparks.
Video of Galaxy Pair VV 191 (Webb and Hubble Composite Image)
Combining the data from the NASA/ESA/CSA James Webb Space Telescope and the NASA/ESA Hubble Space Telescope, researchers were able to trace light that was emitted by the large white elliptical galaxy at left through the spiral galaxy at right and identify the effects of interstellar dust in the spiral galaxy. This image of galaxy pair […]
Webb Reveals Intricate Networks of Gas and Dust in Nearby Galaxies
The largest survey of nearby galaxies in James Webb Space Telescope (Webb) first year of science operations is being carried out by the Physics at High Angular resolution in Nearby Galaxies (PHANGS) collaboration, involving more than 100 researchers from around the globe. The Webb observations are led by Janice Lee, Gemini Observatory chief scientist at […]
