ves much of the image clashing caused by the atmosphere, using a small, deformable mirror. Distortions from a point of light (like a star) are measured, and the mirror is bent in the adverse administration of the distortion, acclimation the image of the main target seen by the astronomer. These corrections can be made more than 1,000 times every second.


When examination targets in arresting light, astronomers using adaptive optics can aftermath images that rival today’s accepted space-based telescopes. However, to see X-rays, long radio waves, and other frequencies, we must always place telescopes above the atmosphere. Although images using adaptive optics are much more clear and abundant than ever before, the atmosphere of the Earth will always abide to block most wavelengths of electromagnetic radiation.

On the other hand, telescopes on the ground accommodate a few major advantages. The most accessible of these is that they are on the ground, making them easier to access. Although a large allotment of ample observations are agitated out accidentally by astronomers, some advisers still carry out their studies at the telescope, and ground-based observatories are much easier to visit.


Repairs and upgrades to telescopes are also much easier to carry out on the ground than in space. Some space-based observatories, like the upcoming James Webb Space Telescope (JWST), orbit so far from Earth, that visits to repair or update the instruments are impossible.

Another factor in the favor of befitting telescopes on the ground (when possible) is cost. For identical telescopes, it is much less big-ticket to build a telescope on the ground than to place it into orbit around the Earth or the Sun.

The atmosphere of Earth will always block most wavelengths of the em spectrum. When celebratory at those frequencies, we will always need to place instruments above the atmosphere. However, when belief targets in arresting and short-wavelength radio waves, ground-based observatories are here to stay for a long time.

Astronomy News with The Cosmic Companion is also accessible as a weekly podcast, agitated on all major podcast providers. Tune in every Tuesday for updates on the latest astrochemistry news, and interviews with astronomers and other advisers alive to bare the nature of the Universe.
