One detection (encoded in digital form) requires a total of less than 100 bits.
The detection of hidden crevasses requires care and experience.
The detection of an Earth-like planet would require about 10 hours of observation in total, spread out over several months.
Its detection requires a different analysis technique, allowing for averaging signal's energy irrelevant of the phase 2.
Early detection requires a delicate balance of watching out for symptoms without letting fear run the show.
The direct detection of gravitational waves requires the measurement of relative displacements and their changes with time.
The detection of a burning hydrogen leak may require a flame detector; such leaks can be very dangerous.
The detection is done using a non-radioactive method and does not require preamplification of the nucleic acid to be detected.
Smaller or more distant planets may also accompany these stars, but their detection would require more prolonged observations and may be beyond current technology.
The detection of smaller objects will require the use of new instruments, such as the proposed James Webb Space Telescope.
