This illustration presents a composite image, juxtaposing the Moon with a simultaneous snapshot of the sky captured by Euclid’s VIS instrument’s 36 detectors. Captured in a single attempt during the spacecraft’s initial test period, the image demonstrates Euclid’s capability to survey a sky area larger than the full Moon in just one telescope orientation. The Moon’s diameter measures roughly 0.5 degrees, in contrast to Euclid, which can observe a sky section of about 0.7 x 0.7 degrees in one observation.

Launched on July 1, 2023, by the European Space Agency, Euclid is tasked with probing the mysteries of the dark Universe. Its first full-color images of the cosmos reveal its superior imaging prowess, made possible by its advanced optics.
Telescope and Optical Technology
Designed to capture wide swathes of the sky in a singular frame, Euclid’s telescope and optics are integral to its mission. This mission aims to chart more than a third of the sky with exceptional sensitivity over six years.
Comparison of Imagery and Scope
A combined image demonstrates the Moon layered over a sky image, captured simultaneously by Euclid’s VIS instrument’s 36 detectors. This image, taken in one go during the early testing stage, highlights Euclid’s ability to encompass a section larger than the full Moon in a single telescope direction. The Moon’s diameter spans around 0.5 degrees, whereas Euclid can capture a square sky section measuring approximately 0.7 x 0.7 degrees in one glance.
VIS and NISP Systems
To attain such extensive coverage, VIS employs 36 CCDs (Charge Coupled Devices, a camera sensor type), arranged in a 6×6 grid with each sensor boasting over 4000×4000 pixels. The NISP instrument incorporates a 4×4 grid of near-infrared sensors, each over 2000×2000 pixels. VIS is responsible for assessing galaxy shapes, and NISP evaluates their luminosity and spectral changes, necessitating fewer but larger-pixel detector arrays.
Euclid stands unparalleled in its ability to observe such a vast area of the sky in one observation with exceptional clarity, spanning both visible and near-infrared spectrums.

Frequently Asked Questions (FAQs) about Euclid Telescope
What is the Euclid Space Telescope?
The Euclid Space Telescope, launched by the European Space Agency (ESA) on July 1, 2023, is a mission dedicated to exploring the dark Universe. It is equipped with advanced optics to capture detailed, full-color images of the cosmos.
How does Euclid’s imaging capability compare to the size of the Moon?
Euclid’s imaging capability is demonstrated by an image overlaying the Moon and a sky image captured by its VIS instrument. The telescope can observe a square area of the sky measuring about 0.7 x 0.7 degrees in a single shot, which is larger than the full Moon’s diameter of approximately 0.5 degrees.
What technology does the Euclid telescope use?
Euclid employs a telescope and optics specifically designed for wide sky coverage in a single shot. Its VIS instrument comprises 36 CCDs (Charge Coupled Devices) arranged in a 6×6 grid, while the NISP instrument uses a 4×4 grid of near-infrared sensors.
What is the mission goal of the Euclid telescope?
Euclid’s mission is to map over one-third of the celestial sphere with high sensitivity within a six-year timeframe. This will contribute significantly to our understanding of the universe, particularly in the study of dark matter and dark energy.

the comparison with the moon’s size really puts things into perspective, shows how powerful Euclid is. can’t wait to see the images it captures!
I’m kinda confused about the VIS and NISP instruments, how do they work exactly? anyone got more info on this?
wow, just read about the Euclid telescope, it’s really amazing what they can do now with space tech. capturing bigger than the moon in one shot? that’s wild
This is some next level stuff, ESA always pushing the boundaries. But six years to map a third of the sky, seems like a long time… or is it just me?
