Starbursts in Dwarf Galaxies are a Global Affair |
|
Bursts of star making in a galaxy have been compared to a Fourth of July fireworks display: They occur at a fast and furious pace, lighting up a region for a short time before winking out. But these fleeting starbursts are only pieces of the story, astronomers say. An analysis of archival images of small, or dwarf, galaxies taken by NASA's Hubble Space Telescope suggests that starbursts, intense regions of star formation, sweep across the whole galaxy and last 100 times longer than astronomers thought. The longer duration may affect how dwarf galaxies change over time, and therefore may shed light on galaxy evolution. |

Beyond JWST:The Next Steps in UV-Optical-Near IR Astronomy
The Association of Universities for Research in Astronomy (AURA) is sponsoring a
workshop to
engage the UV/optical/Near-IR astronomy community to discuss its long-term goals
for space-based
astronomy and astrophysics. The meeting will provide the UVOIR community an
opportunity to look
forward on a 25-year horizon to identify the scientific opportunities enabled by
large and very
large space telescopes and to outline a path forward that will form the basis
for a community-led
report to the 2010 Decadal Review Committee.

2009 May Symposium: The Search for Life in the Universe
The concept that life might exist elsewhere besides the Earth has intrigued humankind for centuries. Technology
has now enabled this fundamental question to be pursued with substantial international scientific vigor. The
2009 May Symposium, to be held May 4-7, 2009 at the Space Telescope Science Institute, will divide discussion
of the motivations and expectations for the search for life in the universe into three distance domains that
each require markedly different observational approaches and speakers from multiple disciplines: detecting Life
within 50 AU of Earth, detecting life within 100 pc of Earth,and detecting life beyond 100 pc from Earth.

Webb Telescope Approved for Development/Launch
On July 10, 2008, NASA formally approved the JWST project to move into its implementation phase. This decision followed a successful Preliminary Design
Review (PDR) in March 2008 and a Non-Advocate Review in April. While all the science instruments and the "long lead" items like the primary mirror segments
are already being manufactured, this approval marks the transition of the program into Phase C (Final Design and Fabrication). Phase D covers system
assembly, integration and testing and launch. Read more...
HLA Data Release 2.5 Includes Contributed Products
The Hubble Legacy Archive (HLA) has entered its Data Release 2.5
(DR2.5) phase of operation. The highlight of DR2.5 is the inclusion
of contributed products from the community. These include: ANGST (ACS
Nearby Galaxy Survey), APPP (Archive Pure Parallels Program), COMA
(ACS Treasury Survey of the Coma cluster), COSMOS (Cosmic Evolution
Survey), GEMS (Galaxy Evolution from Morphologies and SEDs), GOODS
(Great Observatories Origins Deep Survey), SGAL (Spiral Galaxies), a
subset of Hubble Heritage images, STAGES (Space Telescope A901/902
Galaxy Evolution Survey), and UDF (Ultra Deep Field). Other
contributed products are also available from MAST (Multimission
Archive at STScI), and will be included in the HLA in the near future.
The HLA project is a collaboration between the Space Telescope Science Institute, the Space Telescope European Coordinating Facility, and the Canadian Astronomy Data Centre. Read more...
