Ground-based observatories have the drawback that at infrar ed wavele ngths or freque ncies both th e Earth's atmosphere and the telescope itself will radiate brightly. Additionally the atmosphere is opaque at most i nfrared wavelengths. This necessitates lengthy exposure times and greatly decreases the ability to detect faint objects.
