Intense Exercise during Long Space Flights Helps Astronauts Protect Aerobic Capacity

Many astronauts experience a dip in aerobic capacity during long space flights which can impair their ability to perform complex and demanding routine tasks. In an article published in the Journal of Applied Physiology, NASA researchers find that regular, intense in-flight exercise helps preserve cardiovascular stamina. The article is highlighted as part of the APSselect program.

NASA Telescopes Help Uncover Early Construction Phase of Giant Galaxy

p1437aw.jpg

The birth of massive galaxies, according to galaxy formation theories, begins with the buildup of a dense, compact core that is ablaze with the glow of millions of newly formed stars. Evidence of this early construction phase, however, has eluded astronomers — until now. Astronomers identified a dense galactic core, dubbed "Sparky," using a combination of data from Hubble and Spitzer, other space telescopes, and the W.M. Keck Observatory in Hawaii. Hubble photographed the emerging galaxy as it looked 11 billion years ago, just 3 billion years after the birth of our universe in the big bang.

Scientist Uncovers Red Planet’s Climate History in Unique Meteorite

Was Mars — now a cold, dry place — once a warm, wet planet that sustained life? Research underway at the National High Magnetic Field Laboratory may one day answer those questions — and perhaps even help pave the way for future colonization of the Red Planet. By analyzing the chemical clues locked inside an ancient Martian meteorite known as Black Beauty, Florida State University Professor Munir Humayun and an international research team are revealing the story of Mars’ ancient, and sometimes startling, climate history.

Orion Rocks! Pebble-Size Particles May Jump-Start Planet Formation

Fullcomposite.jpg

Astronomers using the Green Bank Telescope have discovered that filaments of star-forming gas near the Orion Nebula may be brimming with pebble-size particles -- planetary building blocks 100 to 1,000 times larger than the dust grains typically found around protostars.

Research Uncovers Forces That Hold Gravity-Defying Near-Earth Asteroid Together

The UT team studied near-Earth asteroid 1950 DA and discovered that the body, which rotates so quickly it defies gravity, is held together by cohesive forces called van der Waals, never detected before on an asteroid.

Baby Black Holes Zigzagged, Ate a Lot to Become Quasars

Giant quasars from shortly after the Big Bang are a mystery: how could a small black hole get so large, so quickly? The Weizmann Institute’s Prof. Tal Alexander and Yale’s Prof. Priyamvada Natarajan have a theory: the hungry, newborn black hole moved around and ate everything in sight.
