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
