Several billion miles from Earth, Neptune's looking particularly sharp in a set of new images captured by one of the most powerful telescopes in the world. 。
Located in Chile, the European Southern Observatory's Very Large Telescope (VLT) used what's known as laser tomography to capture test images of the planet and surrounding star clusters. 。
SEE ALSO:These are the clearest views of Saturn's moon Titan we've seen yet。The telescope's Multi Unit Spectroscopic Explorer (MUSE) instrument works with what's called the GALACSI adaptive optics module.This allows the telescope to correct for turbulence at different altitudes in the atmosphere, resulting in some incredibly clear, sharp images captured from Earth.。
MUSE is the first instrument to benefit from two adaptive optics modes: wide field and narrow. The narrow field mode is what's generating these incredibly sharp images of Neptune — it corrects almost。 all 。all 。

Thanks for signing up!。

The image on the left is from MUSE in Wide Field Mode, without the adaptive optics system in operation and the centre panel is an enlargement of a small part of this view.

Several billion miles away and looking crisp. While you're out there, why not drop by Titan, Saturn's equally sharp-looking moon?
