A team of European Space Agency (ESA) scientists detected an Einstein Ring, in which light from one galaxy is sucked into the gravity of another, then encircles it. The team reported the finding in the journal Astronomy & Astrophysics.The phenomenon is named after Albert Einstein, because his general theory of relativity predicts that light will bend around objects in space, focusing the light like a massive lens. The larger the object, the bigger the gravitational lensing effect appears. If ...read more

Science journalist Maria Smilios was editing a book on orphan lung diseases when one line caught her attention. In a chapter about a rare lung disease, the author commented that perhaps a cure could be discovered as quickly as the cure for tuberculosis was found at Sea View Hospital on Staten Island in the 1950s. Smilios began researching and learned how the first clinical trial for a lifesaving antibiotic happened at Sea View under the watchful supervision of experienced nurses — all of them ...read more
NASA intends to take an unprecedented 3D observation of the sun this month. In doing so, the agency hopes to understand why its outer atmosphere — the corona — is hotter than its surface, how does the solar wind work, and how the corona transforms into solar wind. As a bonus, the mission will take 3D pictures of a solar eclipse, from space.Learning More About the Sun's SurfaceThe system that will make these things possible is made up of four small satellites that will work together to create ...read more
