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 →
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...

This blog post is one in a series marking the 30th anniversary of the launch of the Hubble Space Telescope. For more information and resources regarding Hubble’s 30th anniversary, please visit hubblesite. Thirty years is a long time. In fact, thirty years is roughly the span of a generation. Thus, it is no exaggeration to say that an... Continue Reading →
The Hubble Space Telescope recently observed an asteroid in the process of falling apart. Known as 6478 Gault, located in the main asteroid belt of our solar system between Mars and Jupiter, and roughly 2.5 miles wide, this asteroid is rotating so fast—about once every 2 hours—that it is literally flinging itself apart. The observations... Continue Reading →
You may have noticed that our favorite red planet, Mars, has been a popular feature in the news recently. Not that we need any special reasons to take a closer look at Mars, but a number of coincident events have brought this about: [1] Mars has just passed through opposition, or the point in its...

August 17, 2017 was a watershed moment in the nascent field of gravitational-wave astronomy. On this date, the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected a ripple in space-time, hereafter known as GW170817, originating near the constellation Hydra. A short while later, NASA's Fermi Gamma-ray Burst Monitor detected a faint pulse of gamma rays in this... Continue Reading →
