![]() NASA’s James Webb Space Telescope has captured the distinct signature of water, along with evidence for clouds and haze, in the atmosphere surrounding a hot, puffy gas giant planet orbiting a distant Sun-like star. ![]() Gas gets heated to extremely high temperatures as it folds and becomes very bright, “40 billion times the luminosity of our sun’s,” she explained. “We cannot see the black hole itself, but we see the material swirling around being swallowed,” Giardino said. But it revealed an active black hole, according to ESA astronomer Giovanna Giardino. When the near-infared view is stripped away from the image, mostly gas and dust is seen. Mark McCaughrean, the senior adviser for science and exploration at the European Space Agency, said the image shows the view from our own Milky Way to far-away galaxies - even showing the creation of new stars. “Webb’s mosaic contains more than 150 million pixels and is constructed from about 1,000 image files,” according to NASA. Four of the five galaxies in the group “are locked in a cosmic dance of repeated close encounters,” according to a NASA statement. This compact galaxy group, first discovered in 1787, is located 290 million light-years away in the constellation Pegasus. The space telescope’s view of Stephan’s Quintet reveals the way galaxies interact with one another and how their interactions might shape galactic evolution. The information from Webb provides new insights into how galactic interactions may have driven galaxy evolution in the early universe. It contains over 150 million pixels and is constructed from almost 1,000 separate image files. This enormous mosaic is Webb’s largest image to date, covering about one-fifth of the Moon’s diameter. Today, NASA’s James Webb Space Telescope reveals Stephan’s Quintet, a visual grouping of five galaxies, in a new light. “So it’s a matter of picking and choosing colors that enhance the details and the structure in the image itself,” said Alyssa Pagan, science visual developer. “The reason we want to color the images is that there’s actually more information that you can get if you see it in color.” “We’re basically translating light that we can’t see into light that we can see by applying color, like red, green and blue to different filters that we have from Webb,” said Joe DePasquale, a senior science visuals developer. It takes a trained eye to take the exquisite data and pull out the beauty and the science potential. Targets have to be selected because Webb can’t see the whole sky at any given time to “avoid the mirror seeing direct sunlight” so it stays cold. They also put colors in the images so more information can be extracted.Ī committee was created to come up with a long list of targets to take the best images, according to Klaus Pontoppidan, a Webb project scientist. Scientists put in a lot of work into thinking about how images taken by the James Webb Space Telescope will show light that the human eye cannot see.
