Engineers Heat Up Dark Universe Telescope, Restoring Euclid’s Sight
The European Space Agency’s (ESA) Euclid telescope is back in action after an experimental procedure restored its ability to see the light in the cold, dark depths of space. After noticing a gradual dip in the amount of light measured by Euclid from its surrounding stars, the team behind the mission devised a plan to…

Physicists Measure Gravity of Smallest Mass Yet
Despite keeping us grounded and warping light that travels through space, gravity is actually quite a weak force. The smaller the mass, the less gravity appears to have any pull, until at quantum scales it appears to have no force at all. Now, physicists in England and Europe have measured a tiny—but apparent—gravitational pull on…

With Euclid’s First Dazzling Images, Webb Finds a Worthy Rival in Deep Space
Earlier this morning, ESA released the Euclid space telescope’s first scientific images, offering a glimpse into its mission to explore the “dark universe”—the mysterious 95% of the cosmos made up of dark matter and dark energy. The five images were chosen for their scientific value and public appeal, as the ESA team naturally wants to…

Shell Galaxy Reveals Its Onion-Like Layers to Dark Energy Camera
Behold a galactic onion: the shell galaxy NGC 3923, spotted by the Cerro Tololo Inter-American Observatory’s Dark Energy Camera (DECam) at a distance of about 70 million light-years from Earth. Shell galaxies make up approximately 10% of all elliptical galaxies, one of the three main galaxy types. The other two types are spiral galaxies, like…
