The loop was seen using the European space telescope XMM-Newton to study it in X-ray wavelengths.
Finding them in ever-more-distant galaxies was a primary reason for building the Hubble space telescope.
The Hubble's successor, the Next Generation Space Telescope, will also produce vast quantities of new data.
This confirms a hypothesis from the Hubble Space Telescope, which detected signs of ozone around that Moon.

Scientists have recorded the sound of three stars similar to our Sun using France's Corot space telescope.
Users of the Fermi space telescope have now confirmed these observations, which were first made by amateur astronomers.
He then examined a picture taken by the Hubble space telescope of a galaxy several billion light-years away.
P4 was discovered in 2011 in images taken by the Hubble Space Telescope.

It was acquired by the Herschel Space Telescope and the release marks the observatory's second year in orbit.

Scientists suspected the ring might be present and had the perfect tool in the Spitzer space telescope to confirm it.
In 1999, it deployed the powerful Chandra X-ray space telescope, with the first female commander at the helm, Eileen Collins.
Future aperture upper limits on balloon-borne telescopes are expected to be some 2.5-meters, about the size of the Hubble Space Telescope.

There is doubt also over the future of the James Webb Space Telescope in which Europe has a 15% share.
Here, just so you can compare, are photos that the Hubble Space Telescope took of the planet Pluto, the outermost planet.
Once such a planet is discovered, the next step belongs to the James Webb Space Telescope, which will launch in 2018.
Merlin's images in the radio region of the spectrum are of comparable quality to those of the Hubble Space Telescope observing optically.

Within lay the flawed wiring of the Space Telescope Imaging Spectrograph (STIS).
When combined, the data collected from the dishes will provide a level of detail some 10 times sharper than the Hubble Space Telescope.
Indeed, at some wavelengths it should out-perform the Hubble space telescope, which does not even have the handicap of looking through the atmosphere.
Some researchers have already started thinking about how they might use instruments like the planet-hunting Kepler Space Telescope to detect alien moons.
Max Mutchler from the Space Telescope Science Institute says the astronomer who asked for the pictures was then too busy to look at them.
That is four times as much as the Hubble space telescope, a reasonably big piece of science, churned out in its first two decades.
