Holy Horsehead, Batman! You’ve probably seen photos of the famous Horsehead nebula in Orion many times before, but NOTHING like this!
Astronomers have used NASA’s Hubble Space Telescope to photograph the iconic Horsehead Nebula in a new, infrared light to mark the 23rd anniversary of the famous observatory’s launch aboard the space shuttle Discovery on April 24, 1990.
Looking like an apparition rising from whitecaps of interstellar foam, the iconic Horsehead Nebula has graced astronomy books ever since its discovery more than a century ago. The nebula is a favorite target for amateur and professional astronomers. It is shadowy in optical light. It appears transparent and ethereal when seen at infrared wavelengths. The rich tapestry of the Horsehead Nebula pops out against the backdrop of Milky Way stars and distant galaxies that easily are visible in infrared light.
The nebula is part of the Orion Molecular Cloud, located about 1,500 light-years away in the constellation Orion. It is one of the nearest and most easily-photographed regions in which massive stars are being formed.
Think the Milky Way is a big place? Think again — check out this graphic by Arecibo astrophysicist Rhys Taylor, which neatly illustrates the relative sizes of 25 randomly-selected galaxies using images made from NASA and ESA observation missions. It even includes a rendering of our own remarkably mundane galaxy at the center for comparison.
(Warning: this chart may adversely affect any feelings of galactic superiority you may have once held dear.)
Every once in a while an astronomy book comes out that combines stunning high-definition images from the world’s most advanced telescopes, comprehensive descriptions of cosmic objects that are both approachable and easy to understand (but not overly simplistic) and a gorgeous layout that makes every page spread visually exciting and enjoyable.
This is one of those books.
Looking like something out of a Tim Burton movie, the eerie shapes seen above are part of a cloud of gas and dust located 1,200 light-years away in the constellation Cepheus. First identified in 1966, the human-like figures with “arms” raised give the nebula its spooky nickname: the “Ghost Nebula”.

If you’re a fan of space, you may have seen the BBC/Science Channel series “Wonders of the Universe”, hosted by the award-winning physicist Brian Cox. Professor Cox’s natural enthusiasm for astronomy is nothing short of infectious, and his explanations of far-out concepts help bring the amazing mysteries of our Universe down to Earth for anyone to understand and enjoy… and now he and HarperCollins UK are bringing it to your iPad and iPhone!
Do you love astronomy? Do you appreciate science? Do you have a curiosity about the nature of our Universe, how it came to be and what our place is within it? If you are even reading this I assume your answers to all of those questions is a resounding “yes!” and so I present to you this excellent video created by Brad Goodspeed in support of the James Webb Space Telescope:
“I made Vision because I thought the argument for science could benefit from a passionate delivery,” Brad told Universe Today. “Deep down we’re all moved by the stars, and that passion needs to be expressed by methods outside of science’s typical toolbox.”
