The latest images from Euclid, a European mission studying dark matter and dark energy, are spectacularly beautiful—and scientifically promising
A close-up of the star-forming region M78, from a large image captured by the European Space Agency’s Euclid telescope.
As telescopes go, in some ways, Euclid is modest. It sports a 1.2-meter-wide mirror, only half the width of Hubble’s and one fifth the size of the one for the James Webb Space Telescope . But despite its smaller size, Euclid’s mirror is in one important respect superior to those of these two huge observatories: Unlike the narrow field of view provided by Hubble’s and JWST’s mirrors, Euclid’s offers a panoramic vista.
The Abell 2390 image above was made using a combination of observations from Euclid’s two cameras. One, called simply the visible instrument,, detects light similar to what the human eye can see, from the green part of the spectrum out to the near infrared. The other, called the Near-Infrared Spectrometer and Photometer,, can see much further into the near-infrared—out to a wavelength of two microns, roughly three times longer than the longest-wavelength light that our eyes can see.
