In “ An Invisible Epidemic,” Elizabeth Svoboda discusses a type of trauma caused by a person's core principles being violated, such as during wartime. Attempts to force changes in the way of thinking can create depression and quash creativity. As a person on the spectrum myself, I hope that this can be communicated to the general population as well. It is good to see that autism therapists are coming to realize how harmful forcing conformity can be. It would be appropriate to have a more balanced look at which autism therapies actually work to the advantage of the person in therapy, not just the perspectives of those who are looking in from the outside. It seems to ignore therapies such as relationship development intervention (RDI), which allows for more flexibility on the part of the autistic person and those around them while helping them understand more about how social and other situations work, rendering those situations less confusing. In emphasizing past and current views about attempts to change behaviors, however, the piece may imply that applied behavioral analysis (ABA) is the only therapeutic model available. I applaud the approach of allowing people to be who they are and commend the idea that society needs to work harder at accepting neurodiversity. I found it interesting to read “ Rethinking Autism Therapy”, Claudia Wallis's piece on how autism treatment is moving away from “fixing” the condition. Otherwise, we allow JWST to differentiate itself with its eight-spike signature. When the pattern obscures crucial information in a specific target that takes up most of the field, however, the scientists or image processors will go in and manually remove the PSF. While not infeasible, it is difficult to model and subtract such a complex PSF across an entire image. This kind of distribution of light from a single-point source is called a point spread function (PSF) and is unique to each optical system. How this pattern arises is described further in an infographic entitled “Webb's Diffraction Spikes” that you can find at .Īs of late, the calibration pipeline has no feature for removing the spikes. Technically, there are eight diffraction spikes in total: the prominent six spikes he mentions, which are the result of the light diffracting off the edge of each side of the primary hexagonal mirror, and two smaller horizontal spikes, which are caused by the light interacting with the two struts holding the secondary mirror. PAGAN REPLIES: Kramer's intuition is right in that these spikes are caused by the construction of the telescope.
The marvelous photographs made me feel very small, however-many magnitudes as small as a subatomic particle.
The article on the components of JWST was excellent. Are perhaps the images given to astronomers made with such an option on? What is the truth about those pretty six-pointers?īy the way, the six-pointers provide an easy way to tell a JWST photograph from a Hubble image: publicly available Hubble photographs have four-pointed stars.

I am also guessing the photo-processing software used to make the images includes an option for removing them. I am guessing the latter are artifacts resulting from the construction of the telescope. I was stunned by these photographs, first by their beauty and second by the six-pointed stars around bright objects. In one article in the report, “ Behind the Pictures,” by Clara Moskowitz and Jen Christiansen, science visuals developer Alyssa Pagan of the Space Telescope Science Institute comments on how scientists turn raw data from the telescope into images that give a truer representation than what our naked eye can see. Your special report on “ A New Era for Astronomy” includes several photographs from the James Webb Space Telescope (JWST).
