New mass map of distant galaxy cluster is most precise yet Posted: 24 Jul 2014 07:42 AM PDT Astronomers have mapped the mass within a galaxy cluster more precisely than ever before. Created using observations from Hubble's Frontier Fields observing program, the map shows the amount and distribution of mass within MCS J0416.1-2403, a massive galaxy cluster found to be 160 trillion times the mass of the Sun.

Hubble finds three surprisingly dry exoplanets: 'Hot Jupiters' had only one-tenth to one one-thousandth the amount of water predicted Posted: 24 Jul 2014 06:28 AM PDT Astronomers have gone looking for water vapor in the atmospheres of three planets orbiting stars similar to the Sun -- and have come up nearly dry. The three planets, known as HD 189733b, HD 209458b, and WASP-12b, are between 60 and 900 light-years away from Earth and were thought to be ideal candidates for detecting water vapor in their atmospheres because of their high temperatures where water turns into a measurable vapor.
