    Neil Gehrels Swift Observatory

    Launched: November 20, 2004

    Overview

    The Swift Observatory, renamed in honor of Neil Gehrels, is designed to detect gamma-ray bursts and rapidly pivot to observe their afterglows. Its multi-wavelength capabilities and quick response time have revolutionized our understanding of these violent cosmic explosions.

    Primary Objectives

    • Detect and study gamma-ray bursts (GRBs)
    • Rapidly locate GRBs and notify other observatories
    • Observe the afterglow of GRBs across multiple wavelengths
    • Study high-energy astrophysical phenomena

    Notable Discoveries

    • Detected the most distant gamma-ray burst ever observed
    • Helped confirm the connection between long GRBs and supernovae
    • Discovered the first observation of a kilonova from merging neutron stars
    • Observed the birth of black holes in real-time
