James Webb is once again proving that it can do better than Hubble by revisiting the stars it first captured in the 1990s. This time, the Pillars of Creation in the Eagle Nebula are shown in a new light because we can simulate a 3D journey around them, by combining data from Hubble and James Webb.
Is there any need to provide more information about the Pillars of Creation, these structures that span approximately 4 to 5 light-years and have been iconic since 1995 through images taken by the Hubble Space Telescope?

It was clearly visible in the region of the Eagle Nebula (which itself extends 70 x 55 light-years), a nebula discovered by the Swiss astronomer Jean-Philippe Louis de Chaissot in 1745 in the constellation Serpent and which we now know is located 6,500 years away. -7000 light years from the solar system.
We now also know that the Eagle Nebula, also called… Messi 16Messi 16 Or M16, is the youth training area.starsstars by CollapsesCollapses And segmentation A cloudsclouds dense and cold molecularhydrogenhydrogen And dust. Among the formed stars we find massive stars colorcolor White, blue, types O and B. produce an intense flux of radiation ultravioletultraviolet Which, through photoevaporation, erode the cloud, excavating cavities and thus releasing plume-shaped structures that are doomed in the long run.
3D Journey Around the Pillars of Creation
Data collected now using the James Webb Telescope has renewed our knowledge of the Pillars of Creation, and today we can take a kind of realistic 3D reconstructed journey intoComputerComputer Also using Hubble data, e.g NASANASA It appears today in a new video.
” By flying and passing between the columns, viewers learn about their three-dimensional structure and see how they appear differently in Hubble's visible-light view compared to the optical view. InfraredInfrared From the Webb telescope. interviewinterview It helps them understand why we have more than one Space telescopeSpace telescope to observe different aspects of the same object”, Frank Summers, a NASA visualization researcher, explains in a press release: Space Telescope Science Institute (STScI) of Baltimore, who led the film's development team The world of learning.
NASA continues to comment on its new video, explaining that “ Follower WindWind stars and high light energyenergy Hot young stars at the nebula's center are responsible for creating the column shapes. The video then takes a journey into the 3D structure of the columns. Based on the scientific findings, astronomers and artists modeled this impressive formation in three dimensions and created a sequence that flies through the columns. What might look like three connected columns in a 2D image separates into four clouds of dust from which it escapes GasGas Ionized. As the virtual camera scans the model, the view switches between visible light from Hubble and infrared light from Webb. The audience gets a sense of the contrasting observations and how the telescopes complement each other by examining different scientific aspects of the clouds. Title Pillars of creation It comes from the fact that stars form inside these clouds. The visual tour highlights the different stages of star formation, including a ProtostarProtostar Embedded at the top of the central column, dipole jets emanate from an invisible forming star at the top of the left column and a newborn star in the middle of the left column “.
