A spiral galaxy, NGC 7456. It shines brightly at the centre, and most of its disc also glows in warm colours. Its two spiral arms, which wind outwards from the centre, are made up mostly of large patches of bright blue specks. They also contain thin, reddish clouds of dust, and bright pink bubbles of glowing gas, where stars are forming. Distant galaxies can be seen around the galaxy as small orange spots, on a dark background.
For the Bible’s description of the Universe, try doing something creationists rarely seem to do – actually read it (you don’t need to read much!). In the very first chapter we find a story of a universe created from nothing by a few magic words. This universe is described as a small, flat, dome-covered world, with stars portrayed as tiny lights stuck to the dome. The Sun and Moon are described as lamps hanging from it. Later, we read of stars shaking loose and falling to Earth during earthquakes, and of the Moon hiding in a valley during the day (Genesis 1:6-10, Genesis 1:14-17, Joshua 10:12-14).
The contrast with what science has revealed could hardly be more stark. Given what we now know of the cosmos, the Bible’s account reads like the imaginative attempt of a five-year-old child asked to describe the Universe after a glance at the night sky. It can scarcely be regarded as a definitive scientific account of reality, and yet there are adults who still believe it is just that.
What this tells us about the education and credulity of those creationists who insist on believing such absurdities I will leave for readers to decide. Meanwhile, here is the NASA/ESA Hubble Picture of the Week to compare with the biblical version. It shows the spiral galaxy NGC 7456, located more than 51 million light-years away in the constellation Grus (the Crane). The image reveals glowing pink reservoirs of gas where new stars are forming, their light causing the surrounding gas to emit its tell-tale red glow.
While it may appear unassuming at first glance, just another spiral galaxy among thousands in the Universe, this subject of the ESA/Hubble Picture of the Week has plenty to study. NGC 7456 is its name, located over 51 million light-years away in the constellation Grus (the Crane).
In this image we see in fine detail the patchy spiral arms of this galaxy, followed by clumps of dark, obscuring dust. Blossoms of glowing pink are rich reservoirs of gas where new stars are forming, illuminating the clouds around them and causing the gas to emit this tell-tale red light. The Hubble programme which collected this data is focused on stellar activity just like this, tracking new stars, clouds of hydrogen and star clusters to learn how the galaxy has evolved through time.
Hubble, with its ability to capture visible, ultraviolet and some infrared light, is not the only observatory focused on NGC 7456. ESA’s XMM-Newton satellite has imaged X-rays from the galaxy on multiple occasions, discovering a number of so-called ultraluminous X-ray sources. These small, compact objects emit terrifically powerful X-rays, much more than would be expected for their size. Astronomers are still trying to pin down what powers these extreme objects, and NGC 7456 contributes a few more examples.
On top of that, the region around the galaxy’s supermassive black hole is spectacularly bright and energetic, making NGC 7456 an active galaxy. Whether looking at its core or its outskirts, at visible light or X-rays, this galaxy has something interesting to show!

The difference between the Bible’s cosmology and the universe revealed by science could not be more profound. One is the product of a pre-scientific culture, imagining the heavens as a solid dome above a flat earth. The other is a reality of galaxies, nebulae, and cosmic processes unfolding across billions of years and light-years.
That some still insist the former is a literal account of reality is a measure not of its accuracy, but of their willingness to ignore the evidence before our eyes. Science has given us the tools to understand our place in a vast, evolving cosmos; clinging instead to ancient myths diminishes both the universe and our ability to appreciate it.

What Makes You So Special? From The Big Bang To You
How did you come to be here, now? This books takes you from the Big Bang to the evolution of modern humans and the history of human cultures, showing that science is an adventure of discovery and a source of limitless wonder, giving us richer and more rewarding appreciation of the phenomenal privilege of merely being alive and able to begin to understand it all.
Ten Reasons To Lose Faith: And Why You Are Better Off Without It
This book explains why faith is a fallacy and serves no useful purpose other than providing an excuse for pretending to know things that are unknown. It also explains how losing faith liberates former sufferers from fear, delusion and the control of others, freeing them to see the world in a different light, to recognise the injustices that religions cause and to accept people for who they are, not which group they happened to be born in. A society based on atheist, Humanist principles would be a less divided, more inclusive, more peaceful society and one more appreciative of the one opportunity that life gives us to enjoy and wonder at the world we live in.
