Wild Theory Suggests Dark Matter Could Make Stars Immortal
Stars very close to the center of our galaxy could be fueled by dark matter in perpetuity, according to a team of astronomers who recently studied the distant light sources. The group of stars, known as S-cluster stars, is just three light-years from the center of the Milky Way (for reference, we are about 26,000…

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…
