SPACE ENGINE DIFFRACTION SPIKES SUPER SERIES

On the right is a simplified diagram of the light path through this instrument.Ĭredit: NASA’s Goddard Space Flight CenterĮven within the detector there are multiple mirrors guiding the light through the instrument and filters and ultimately down to the detector that records that light. On the left we see a schematic diagram of Hubble’s WFC3 instrument module. NASA provides lots of great resources for those curious about this, but I will summarize it here. Let’s take a look at the path of light entering the telescope before it nestles down into one of Hubble’s detectors and is recorded in an image exposure. Understanding this will help in identifying some of these image artifacts. But before we dig into that process, and in order to better understand the source of image artifacts, we must first take a step back and gain some perspective on how Hubble works. The data are in their most raw state during this phase, and individual images are added together to create the initial set of images that are combined in color to produce a press release image. Many artifacts are caught and cleaned up during the pre-processing phase of data preparation. These terms describe the ways in which we remove image artifacts. If you’ve followed along on the blog for any length of time, you’ve likely encountered posts where we have discussed the process of data calibration, pre-processing, and cleaning of the image. It is the job of an image processor to reduce the presence of these image by-products as much as possible while maintaining the integrity of the data in the process of creating press-quality imagery. If left in the final image, these artifacts could easily become a source of confusion or distract from the science inherent in the image. Ghosts, spikes, and dragon’s breath…No, it’s not a Hubble-themed spinoff of Game of Thrones (but what would THAT be like?)…These are terms used to describe some of the many artifacts present in the raw data taken by the Hubble Space Telescope. In this post, we’ll look at the distracting image artifacts that are removed when creating press imagery.

This series of posts is dedicated to the scrutiny of Hubble imagery and a broader discussion of the veracity of astronomical imagery. Tl dr the system is complicated and unrealistic.TLDR: Yes, Hubble images are real. Setting up this shot was an absolute pain in the arse as both stars had to be perfectly lined up while orbiting in differing directions, at different SMA, at different angles and at different speeds. If the light was coming solely from the black hole disk, we would see a 'sunset' very close to the visible edge of the planet, and about 3/4 of the rest of the planet towards the bottom of the screenshot would be entirely dark. However, there is also a second star right above the shot (literally less than 1 degree) above the top of the image that illuminates the planet to replicate the unrealistic illumination shown in the movie. The diffraction spikes coming from the disk is indeed a star superimposed onto the disk with very high brightness values. The post above this reply has half the answer correct.

The diffraction spikes are coming from the brighter part of the accretion disk instead of the center.

Eh I did a recreation of a shot in Interstellar using only SpaceEngine.
