Center for Advancement of Science in Space (CASIS) awarded grant funding to UCLA for stem cell researchers to send rodents into space to test new therapy for prevention of bone loss. Research has enormous translational potential for astronauts in space flight and patients on Earth with osteoporosis or other bone loss problems from disease, illness or trauma.

“Assassin” Targets Supernovae in Our Neighborhood of the Universe

View | Comment

While many astronomical collaborations use powerful telescopes to target individual objects in the distant universe, a new project at The Ohio State University is doing something radically different: using small telescopes to study a growing portion of the nearby universe all at once. Since it began, the project has detected 89 bright supernovae and counting—more than all other professional astronomical surveys combined.

Hubble Discovers that Milky Way Core Drives Wind at 2 Million Miles Per Hour

View | Comment

At a time when our earliest human ancestors had recently mastered walking upright, the heart of our Milky Way galaxy underwent a titanic eruption, driving gases and other material outward at 2 million miles per hour. Now, at least 2 million years later, astronomers are witnessing the aftermath of the explosion: billowing clouds of gas towering about 30,000 light-years above and below the plane of our galaxy.

Hubble's High-Definition Panoramic View of the Andromeda Galaxy

View | Comment

The largest NASA Hubble Space Telescope image ever assembled, this sweeping view of the Andromeda galaxy (M31) is the sharpest large composite image ever taken of our galactic neighbor. Though the galaxy is over 2 million light-years away, the Hubble telescope is powerful enough to resolve individual stars in a 61,000-light-year-long section of the galaxy's pancake-shaped disk.
