TLDR: Yes, Hubble images are real. This series of posts is dedicated to the scrutiny of Hubble imagery and a broader discussion of the veracity of astronomical imagery. In this post, we’ll look at a few examples of how Hubble extends beyond human vision to illuminate our understanding of the universe.

What is "true color"? Is it what our eyes see, or is it something else entirely?
We often make the case here that astronomical imagery created to support the dissemination of Hubble’s scientific results to the general public relies on a delicate balance of aesthetics and science. The image above provides a great study in how these two aspects of the image come together in the publication of a press release.... Continue Reading →
Jayanne English, an astronomer with a visual arts background, outlines the process of making an illuminating image for the public from a rich set of research data. Exploring how galaxies change with time requires the study of how visible light and non-visible radiation are interconnected. With the Hubble Space Telescope (HST) we can map, often in...

Jupiter and Saturn made a big splash last month due to the historic conjunction of our solar system’s two largest planets. From our vantage point here on Earth, looking out onto the flat plane of the sky, a conjunction occurs when two or more celestial bodies seem to slide right past each other in the...

I was recently asked about things that spin in the universe. Planets spin. Stars spin. Galaxies spin. Why do they spin, and how do they acquire that spin? This blog post contains my response. I’m going to go through things slowly, and build up concepts, so bear with me. A spinning top [Credit: randomname123 at... Continue Reading →

The Sleeping Giant—Elliptical Galaxy NGC 4889 The majestic yet placid appearance of this serene galaxy, NGC 4889, is deceiving to the unsuspecting observer. Captured in this NASA/ESA Hubble Space Telescope image,... Continue Reading →
