The first images released last week from the James Webb Space Telescope were accompanied by hundreds of data points made available to the scientific community. Now many scientists and enthusiasts are digging with great interest into this raw data to see what they can find.
One of them is Judy Schmidt, who has been studying raw space data for years to get stunning images. Thanks to her painstaking work, we now have absolutely stunning images of two spectacular spiral galaxies.
The first is NGC 628, also known as the “ghost galaxy,” Fan, or M74. The other is NGC 7496. Both are relatively close to the Milky Way and are the subject of observations in the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) study, to better trace the connections between young stars and gas clouds. cold molecular that originate them.
Magenta version of the Fan galaxy
Among the enthusiasts is also the astronomer Gabriel Brammer, who works for the Niels Bohr Institute at the University of Copenhagen, and who has also uploaded his version to his Twitter account.
The astronomer published the image in which the spiral-shaped Fan galaxy can be seen, with spectacular colors in the magenta range, and accompanied it with a comment: “Let’s see what JWST (the James Webb Space Telescope ) observed yesterday…. Oh my God.”
The Fan Galaxy, Brammer noted in an interview with the independent“It probably looks a lot like what we think our own Milky Way is like.”
NGC 628 had already been photographed by the Hubble Space Telescope, which gave it an image with more blue, cream and brown colors.
The Hubble, which has been in service for three decades, operates mainly with visible light, while the James Webb works in the infrared spectrum, one of the keys by which it can offer a vision in greater detail than those known until now.
To understand the impact that the James Webb is having, it is only necessary to compare both images.
The Hubble image of the galaxy NGC 628 is a composite of data from the telescope’s Advanced Camera for Surveys taken in 2003 and 2005.
The first images from the James Webb Telescope
The first official image resulting from the observations of the largest and most sophisticated telescope sent into space was released by US President Joe Biden on July 11 and, a day later, by the institutions collaborating on the Webb – the US NASA, the European Space Agency (ESA) and the Canadian (CSA) – published another series of them.
