1) Is there intelligent life elsewhere in the universe?
2)A problem that NASA has faced: Assuming that in one of our space probes we are to place a message to other intelligent beings in the universe–on the chance that such a being will find it someday–what should that message be, and how should it be expressed?

Explanation:
Life Beyond Earth
Since the beginning of civilization, humanity has wondered whether we are alone in the universe. As NASA has explored our solar system and beyond, it has developed increasingly sophisticated tools to address this fundamental question. Within our solar system, NASA’s missions have searched for signs of both ancient and current life, especially on Mars and soon, Jupiter’s moon Europa. Beyond our solar system, missions, such as Kepler and TESS, are revealing thousands of planets orbiting other stars.

The explosion of knowledge of planets orbiting other stars, called exoplanets, and the results of decades of research on signatures of life - what scientists call biosignatures - have encouraged NASA to address, in a scientifically rigorous way, whether humanity is alone. Beyond searching for evidence of just microbial life, NASA now is exploring ways to search for life advanced enough to create technology.
Technosignatures are signs or signals, which if observed, would allow us to infer the existence of technological life elsewhere in the universe. The best known technosignature are radio signals, but there are many others that have not been explored fully.
In April 2018, new interest arose in Congress for NASA to begin supporting the scientific search for technosignatures as part of the agency’s search for life. As part of that effort, the agency is hosting the NASA Technosignatures Workshop in Houston on Sept. 26-28, 2018, with the
Explanation:
1. There's high chance of finding an intelligent civilization elsewhere in the universe. Still we are unable to find that, The reason could be of them being beyond the reach.
2. We have did it previously of embedding a message, but none was the result. The message can be in the form of radio signal or being embedded in spacecrafts . The message , if SOS message can get us more attention.
