From a young age, astrophysicist Robin Cook had a deep desire to understand the world around him. “It’s never nice enough to take things at face value … I’ve always wanted to understand how things work,” he said. It was this natural curiosity that led him to pursue a career researching space and the unknown. “It’s not too surprising that I naturally went into astronomy,” he said. “There are so many unanswered questions in astronomy, we actually have pretty limited knowledge of what’s really out there. “And for me, it’s very interesting.” Seeing the galaxy’s ‘beautiful spiral’ Dr Cook is a research associate at the International Center for Radio Astronomy Research (ICRAR), which is run by Curtin University and the University of Western Australia. Founded in 2009, the research center conducts data-intensive astronomy, engineering and science. Dr Cook studies the structure of galaxies.

The stars in new images from the James Webb Space Telescope look sharper than ever before. And I’m not just talking about the image quality, which is amazing. I talk about the fact that many of the bright stars in the picture have very different nails from the Christmas decorations or, as one of my colleagues put it, “This looks like a JJ Abrams promo poster, and I love it. ” But this is not a case of too much lens flare. Those are diffraction spikes, and if you look closely, you’ll see that all the bright objects in the JWST image have the same eight-pointed pattern. The brighter the light, the more prominent the features. Dimmer objects such as nebulae or galaxies are less likely to see this distortion. This diffraction spike pattern is unique to JWST. If you compare the images taken by the new telescope with the images taken by its predecessors, you will see that Hubble only has four diffraction spikes for the eight JWSTs. (Two JWST spikes can be very dim, so sometimes it ap
