• Study estimates amount of water needed to carve Martian valleys

  05-06-2017 06:00
  
  (Northern Illinois University) A new Northern Illinois University study calculates the amount of water needed to carve the ancient network of valleys on Mars and concludes the planet's surface was once much more watery than previously thought. The study bolsters the idea that Mars had a warmer climate and active hydrologic cycle, with water evaporating from an ancient ocean, returning to the surface as rainfall and eroding the extensive network of valleys.

• Hubble's tale of 2 exoplanets: Nature vs. nurture

  05-06-2017 06:00
  
  (NASA/Goddard Space Flight Center) Is it a case of nature versus nurture when it comes to two 'cousin' exoplanets? In a unique experiment, scientists used NASA's Hubble Space Telescope to study two 'hot Jupiter' exoplanets. Because these planets are virtually the same size and temperature, and orbit around nearly identical stars at the same distance, the team hypothesized that their atmospheres should be alike. What they found surprised them.

• ALMA returns to Boomerang Nebula

  (National Radio Astronomy Observatory) An ancient, red giant star has produced the coldest known object in the cosmos. How this star was able to create an environment strikingly colder than the natural background temperature of deep space has been a compelling mystery for more than two decades. The answer, according to astronomers usingALMA, may be that a small companion star has plunged into the heart of the red giant, ejecting most the matter of the larger star as an ultra-cold outflow of gas
