Meet Euclid’s first comet discovery: ‘C/2026 S1 (Euclid)’

Consortium, ESA, People, Publication, Science / By

There are potentially one trillion (1,000,000,000,000) comets flying across our solar system. Made of materials that will melt or vaporize and outgas when being brought to the Sun, comets originate from the far reaches of our solar system, in the Oort Cloud way beyond the last major and minor planets. Of all the possible comets out there, only 4644 have come close to the sun – and actually been observed by humans. Now scientists have added one more, the first found with Euclid data: ‘C/2026 S1 (Euclid)’.

Behind the scenes: Euclid Galactic Bulge Survey (Q2)

Consortium, ESA, People, Publication, Science, Telescope and instruments / By

On 23 March 2025, the Euclid space telescope targeted an unusual location: a region near the Galactic Centre, capturing an exceptionally deep, wide-field, and high-resolution view of the Milky Way’s inner bulge. Over roughly 24 hours, the telescope observed nine contiguous fields, covering a total of 4.8 square degrees, capturing the images of roughly 60 million stars in total. Now the images and catalogues are made public to the world – we take the opportunity to peek behind the curtain to see what makes this image so special and which challenges had to be overcome.

Euclid starts seeing darkness

Consortium, People, Publication, Science / By

Euclid‘s core mission to study the nature of dark energy includes two central probes: one is tracking the expansion history of the Universe, the other traces structure formation over cosmic time. Ahead of the first cosmology results coming out in 2027, scientists have now published a first demonstration that Euclid can indeed trace massive structures dominated by usually invisible dark matter, using the technique of ‘weak gravitational lensing’.
