Time to think big: A call for a giant space telescope

Posted: 22 Jun 2014 07:22 AM PDT

In the nearly 25 years since the launch of the Hubble Space Telescope (HST), astronomers and the public alike have enjoyed ground-breaking views of the cosmos and the suite of scientific discoveries that followed. The successor to HST, the James Webb Telescope should launch in 2018 but will have a comparatively short lifetime.

NASA selects studies for the asteroid redirect mission

Posted: 20 Jun 2014 11:37 AM PDT

NASA has selected 18 proposals for studies under the Asteroid Redirect Mission Broad Agency Announcement (BAA). These six-month studies will mature system concepts and key technologies and assess the feasibility of potential commercial partnerships to support the agency's Asteroid Redirect Mission, a key part of the agency's stepping stone path to send humans to Mars.

Jupiter's moons remain slightly illuminated, even in eclipse

Posted: 20 Jun 2014 07:23 AM PDT

Astronomers have found that Jupiter's Galilean satellites (Io, Europa, Ganymede, and Callisto) remain slightly bright (up to one millionth of their normal state) even when in the Jovian shadow and not directly illuminated by the Sun. The effect is particularly pronounced for Ganymede and Callisto.

NASA's swift satellite tallies water production of Mars-bound comet

Posted: 19 Jun 2014 05:54 PM PDT

In late May, NASA's Swift satellite imaged comet Siding Spring, which will brush astonishingly close to Mars later this year. These optical and ultraviolet observations are the first to reveal how rapidly the comet is producing water and allow astronomers to better estimate its size.
