Explanation:

All three statements about the LOFAR Telescope are correct.

The LOFAR (Low-Frequency Array) Telescope is indeed made up of a network of radio antennas. These antennas are spread across several European countries and are used to observe the universe at low radio frequencies.

It allows scientists to detect radiation produced when massive celestial objects interact. LOFAR is particularly effective in studying astronomical phenomena that emit at low radio frequencies, such as pulsars, high-energy jets from black holes, and interactions of distant galaxies.

LOFAR will help scientists understand the behavior of energetic phenomena. Its capabilities in low-frequency radio observation make it a powerful tool for studying a range of cosmic events and processes, contributing to our understanding of the universe's dynamics.

Therefore, all three statements are correct.
