DECADE.TW / SOLAR GRAVITATIONAL LENS
SEE A WORLD
BEYOND REACH.
A future telescope that turns the Sun itself into a cosmic lens—and distant light into the image of another world.
DISCOVER THE MISSION ↓DECADE.TW / THE MISSION
Not a larger mirror.
A larger idea.
The Solar Gravitational Lens Telescope uses the curvature of spacetime around the Sun to magnify a distant exoplanet. With the planet, Sun, and spacecraft precisely aligned, faint light can become a map of another world.
HOW IT WORKS
From a trace of light
to a planetary image.
Exoplanet
Reflected starlight crosses interstellar space toward our Solar System.
Curved spacetime
The Sun bends passing light inward toward a focal line.
Einstein ring
Magnified planetary information appears around the Sun as a ring.
Reconstruction
The probe samples the signal and reconstructs the surface computationally.
ENGINEERING FRONTIER
Precision engineering
beyond 550 AU.
SGLT combines propulsion, autonomous navigation, coronagraphy, deep-space communications, and computational imaging.
High-speed deep-space flight
Solar-sail concepts could shorten the decades-long journey to the focal region.
Extreme navigation precision
Maintain alignment between target, Sun, and spacecraft across immense distance.
Coronal suppression
Separate the faint Einstein ring from the bright Sun and its dynamic corona.
Computational imaging
Deconvolve mixed measurements into a recognizable planetary map.
A VIEW BEYOND DISTANCE
The next blue world
is waiting in the light.
