Space Station Threshold

This galaxy, Zw II 96 (about 500 million light-years away) resembles the Baby Boom galaxy which lies about 12.3 billion light-years away and appears in images as only a smudge. A group of telescopes got together recently to check out a little hanky-panky going on in the very remote universe. The Hubble and Spitzer [...]

While time travel is seemingly impossible, we can actually look back in time with our telescopes to learn about the conditions of our universe in times past. The Spitzer Space Telescope has found some very dim and distant galaxies located at the edge of our universe that have never been seen before. Approximately [...]

A new image released from NASA's Spitzer Space Telescope shows a baby star blowing bubbles, just like, I guess, a kid with bubblegum. But let's see your kid hurl out material hundreds of kilometres a second across light-years of space. Those are some big bubbles.

Out there, in the darkness of space, a galaxy is committing a robbery. The robber, known as 3C 326 North is a galaxy the size of our Milky Way. Its victim contains about half the mass, and that's going steadily down, because 3C 326 North is stealing some of its gas away.

This newly released photograph taken by the Spitzer Space Telescope is of a previously hidden star cluster, revealed now in the infrared spectrum. At visible wavelengths, this cluster, located in the southern portion of the Serpens cloud would be totally obscured by dust. But now, thanks to Spitzer, we can see it for the first [...]

Galaxies aren't born, they evolve, getting built up through a succession of mergers over billions of years. In most cases, this process is slow and steady, with galaxies tearing apart their satellite neighbours and gaining mass. But in one cosmic collision seen by NASA's Spitzer Space Telescope, 4 extremely massive galaxies are coming ...

The latest image released from the Spitzer Space Telescope shows infant stars “hatching” in the head of Orion. Astronomers think that a supernova 3 million years ago sent shockwaves through the region, collapsing clouds of gas and dust, and beginning a new generation of star formation. The region imaged by Spitzer is called Barnard 30, ...

The latest image released from the Spitzer Space Telescope shows a pair of stars destroying their surroundings with powerful jets of radiation. The stars are located about 600 light-years away in a nebula called BHR 71. The image attached here shows what the object looks like in the infrared spectrum, which can peer through obscuring [...]

When we look into the skies with our eyes, we see in the visible spectrum. Although objects can look beautiful, it’s only a fraction of the entire electromagnetic spectrum. To really see and understand the Universe, you’ll want to look in different regions of the spectrum. The three great observatories: Hubble, Spitzer and Chandra, ...
