It is a mystery that has stymied astrophysicists for decades: how do black holes produce so many high-power X-rays? In a new study, astrophysicists from The Johns Hopkins University, NASA and the Rochester Institute of Technology conducted research that bridges the gap between theory and observation by demonstrating that gas spiraling toward a black hole inevitably results in X-ray emissions.

Johns Hopkins astrophysicists Brice Ménard and Charles L. Bennett have been appointed to the Euclid Consortium, the international team of scientists overseeing an ambitious space telescope project designed to probe the mysteries of dark energy and dark matter. NASA, a partner in the mission, recently announced their selection to the research team for Euclid.
Johns Hopkins engineers, recognized as experts in medical robotics, have turned their attention skyward to help NASA with a space dilemma: How can it fix valuable satellites that are breaking down or running out of fuel? One option—sending a human repair crew into space—is costly, dangerous and sometimes not even possible for satellites in a distant orbit. Another idea is now getting attention: Send robots to the rescue and give them a little long-distance human help. Johns Hopkins scientists say the same technology that allows doctors to steer a machine through delicate abdominal surgery could someday help an operator on Earth fix a faulty fuel line on the far side of the moon.
A team of astronomers, including one at the Johns Hopkins University, has uncovered a burgeoning galactic metropolis, the most distant known in the early universe. This ancient collection of galaxies presumably grew into a modern galaxy cluster similar to the massive ones seen today. The developing cluster, named COSMOS-AzTEC3, was discovered and characterized by multi-wavelength telescopes, including NASA’s Spitzer, Chandra and Hubble space telescopes, and the ground-based W.M. Keck Observatory and Japan’s Subaru Telescope. Johannes Staguhn, associate research scientist at Johns Hopkins University’s Center for Astrophysical Sciences in the Henry A. Rowland Department of Physics and Astronomy, contributed data to uncover the nature of a main cluster member.
Johns Hopkins astrophysicist Charles Bennett has spent his career studying the heavens, so it seems only fitting that he recently took his place among stars of another kind: those inducted into the University of Maryland Alumni Hall of Fame. Bennett, who recently shared the $1 million Shaw Prize in astronomy for his groundbreaking work in determining the age, shape and composition of the universe, now shares this honor with 59 other distinguished University of Maryland luminaries, including Muppet creator Jim Henson, television writer and comedian Larry David, former NFL player Norman “Boomer” Esiason and American choreographer Liz Lerman. He was inducted into the University of Maryland Alumni Hall of Fame on June 5.
