The universe, a vast expanse of cosmic wonders, has long captivated the human imagination. From the earliest moments of gazing at the night sky, to the present day of sending sophisticated observatories beyond our planet’s bounds, humanity’s fascination with the cosmos remains undiminished. Among the many awe-inspiring missions that have been conceived, the Large Observatory for X-ray Timing (LOFT) stands as a testament to our unyielding curiosity and our ceaseless quest to unravel the secrets of the universe.
X-rays, a form of electromagnetic radiation with energies higher than those of visible light, carry unique insights into the most extreme and energetic processes occurring in the cosmos. Neutron stars, remnants of massive stars that have undergone supernova explosions, emit X-rays due to their incredibly strong magnetic fields and rapid rotations.
