This Hubble image shows UGC 11860, a spiral galaxy located some 184 million light-years away in the constellation of Pegasus. The color image is made up of observations from Hubble’s WFC3 camera in the ultraviolet, near-infrared, and optical parts of the spectrum. It is based on data obtained through three filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / A. Filippenko / J.D. Lyman.

Hubble Space Telescope Looks at Supernova-Hosting Spiral Galaxy

ESA’s Euclid spacecraft will orbit the second Lagrange point (L2), 1.5 million km from Earth in the opposite direction to the Sun. L2 is an equilibrium point of the Sun-Earth system that follows Earth around the Sun. In its orbit at L2, Euclid’s sunshield can always block the light from the Sun, Earth and Moon while pointing its telescope towards deep space, ensuring a high level of stability for its instruments. At L2, Euclid joins ESA’s Gaia mission and the ESA/NASA/CSA James Webb Space Telescope, which are also orbiting around this equilibrium point, each following well separated trajectories.
