Hubble Reaches the "Undiscovered Country" of Primeval Galaxies |
|
NASA's Hubble Space Telescope has broken the distance limit for galaxies and uncovered a primordial population of compact and ultra-blue galaxies that have never been seen before. The deeper Hubble looks into space, the farther back in time it looks, because light takes billions of years to cross the observable universe. This makes Hubble a powerful "time machine" that allows astronomers to see galaxies as they were 13 billion years ago, just 600 million to 800 million years after the Big Bang. |

Around The Institute
Astrobiology Lecture Series 2009-2010
The Planets, Life, and the Universe lecture series brings exciting domestic and international speakers on astrobiology to the
STScI and Johns Hopkins University. The monthly lectures are highly multidisciplinary and cover a broad range of topics, from
the formation and evolution of exoplanets through early Earth history to pre-biotic chemistry, the origin of life and biological
evolution. Each lecture is followed by a lively open discussion. The series is funded by the NASA Astrobiology Institute, STScI,
and JHU; the lectures and the ensuing discussion are webcasted and archived, and also open to external parties via Adobe Connect
and streaming video/telecon link. More info...
2010 May Symposium
The 2010 May Symposium will bring together two communities of astronomers, those studying resolved
stellar populations in the nearby Universe and those focusing on better understanding the properties and evolution
of stellar populations in the highest redshift systems. Review and contributed talks will illustrate the latest observational
and theiretical views on the processes that lead to the formation of stellar populations and their stellar, chemical, and dynamical
evolution. The link between star clusters and galaxies and their role as building blocks of more massive systems will also be discussed.
By addressing the limitations of our knowledge of resolved populations, the symposium will improve
our understanding of what can confidently be said about galaxy properties across cosmic time, including new observations
ranging from systems at intermediate redshifts when star formation is peaking, to the first few billion years of the Universe.

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 3.0
HLA Data Release 3 Includes New NICMOS Images,
ACS Grisms, WFPC2 Source Lists, and Prototype Mosaics.
The Hubble Legacy Archive (HLA) has entered its Data Release 3 (DR3) phase of operation. DR3 features several new products and interface upgrades. Highlights include: improved NICMOS single- and multi-exposure images; extracted spectra from ACS GRISM data; source lists for most WFPC2 visits; and a few prototype mosaics from multi-visit ACS data.
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...
