Hubble Cycle 18 Proposal Selection <em>Hubble</em> Cycle 18 Proposal Selection

With a full suite of new or refurbished instruments available to proposers, 1,051 proposals were submitted. As a reflection of Hubble’s new capabilities, Cycle 18 has seen one of the highest oversubscriptions in the history of the telescope. About nine times more orbits were requested than were available, and six times more proposals were submitted than approved.

The Hubble Multi-Cycle Treasury Science Program The <em>Hubble</em> Multi-Cycle Treasury Science Program The Call for Multi-Cycle Treasury Programs was designed to provide the community with an opportunity to exploit Hubble's enhanced capabilities. Three observing programs that incorporated science from four MCT proposals were recommended for execution. (I. Neill Reid and Suzanne L. Hawley)
Optimizing Science with the Hubble Space Telescope Optimizing Science with the <em>Hubble Space Telescope</em>

From maximizing Hubble's capabilities by reducing project turnaround times, to choosing the best mix of proposals and users, to new ways of keeping users informed—we're looking for your input! (Brad Whitmore)


Cosmic Origins Spectrograph News Cosmic Origins Spectrograph News COS was installed on Hubble during Servicing Mission 4 on May 16, 2009. Since then, a vigorous scientific program has been underway using its unique ultraviolet spectroscopic capabilities. By the end of June 2010, COS had been used to make ~3800 science and calibration exposures. (Alessandra Aloisi, for the COS Team)
Enabling New Science with WFC3 Enabling New Science with WFC3 On-orbit measurements of the performance of WFC3 have exceeded expectations. The instrument is 10–20% more sensitive than expected—across the entire UV–VIS–IR wavelength range. (Jason Kalirai, John MacKenty, and the WFC3 Team)
ACS Status ACS Status

The WFC and SBC of the Advanced Camera for Surveys continue to perform well after the repairs made during SM4. All aspects of the WFC performance were checked during the SMOV period. The replacement electronics have given the WFC detectors new characteristics, as explained inside...

STIS Update STIS Update

Since its repair during SM4, the Space Telescope Imaging Spectrograph has resumed its role as an important part of Hubble’s instrument complement; however, there are changes in the detector background for STIS’s Charge Coupled Device and near-ultraviolet Multi-Anode Microchannel Array detectors. (Charles Proffitt)


Webb Update Webb Update

While development of the James Webb Space Telescope is in full swing, important components of the observatory—and the mission itself—recently passed major reviews.

Wavefront Sensing and Control on the James Webb Space Telescope Wavefront Sensing and Control on the <em>James Webb Space Telescope</em>

All optical elements of Webb's optical telescope element are in advanced stages of production. Once assembled and launched, an elaborate process of wavefront sensing and control will be used to co-phase the primary mirror segments and achieve diffraction-limited performance at a wavelength of 2 microns.

MIRI Status MIRI Status

Webb's very versatile Mid-Infrared Instrument will offer imaging through various filters, coronagraphs, and low- and medium resolution spectroscopy. MIRI is taking shape; its assembly and thermal-vacuum testing will take place this year.

Community Missions Office Community Missions Office With the experience the Institute has gained from operating Hubble, building MAST, and preparing for Webb, CMO is the focal point for bringing the benefits of this experience to other missions and projects. What kind of tool or service could we offer to support your mission? (Alberto Conti)
MAST, Multimission Archive at Space Telescope MAST, Multimission Archive at Space Telescope MAST is NASA’s data repository for astronomy missions in the ultraviolet–optical wavelength range, including both active and legacy missions. It supports the astronomical community by facilitating access to its collections, offering expert user support, and providing software for calibration and analysis. The archive currently contains 113 terabytes, and is steadily growing. (Alberto Conti)
Hubble Fellowship News Hubble Fellowship News The Hubble Fellowship Program provides postdoctoral fellowships to candidates of exceptional research promise. This year marked the 20th anniversary of its founding. In honor of that milestone, all past Hubble Fellows were invited to attend the annual Hubble Fellows Symposium. Prof. Giacconi was the keynote speaker. (Ron Allen)
Hubble Fellows, the Future is in Your Hands Hubble Fellows, the Future is in Your Hands

The text of a talk given at the Institute on March 8, 2010, on the occasion of the 20th anniversary of the start of the Hubble Fellowship Program.

May Symposium 2010 May Symposium 2010

"Stellar Populations in the Cosmological Context” was inspired by the enormous progress over the last two decades in the detailed study of nearby, resolved stellar populations, and the discovery and the characterization of high-redshift galaxies. Furthermore, the new panchromatic capabilities of Hubble’s Wide Field Camera 3 are now enabling a new leap forward in exciting research.
(Jason Kalirai and Massimo Robberto)


Hubble Science Year in Review <em>Hubble</em> Science Year in Review

Communicating the wonder of exploration and the excitement of discovery are goals of the Hubble Space Telescope Science Year in Review. Thousands of papers have been written on Hubble results, but the Science Year in Review distills the top annual discoveries into laymen’s terms—complete with full-color, top-flight graphics and illustrations, and a multitude of amazing Hubble images.

Magnetic Filaments in an Active Galaxy Magnetic Filaments in an Active Galaxy

The gossamer-like filaments of NGC 1275 have existed for more than 100 million years. But why have they not heated up, dispersed, and evaporated by now, or simply collapsed under their own gravity?
(Andy Fabian)


Dark Matter and Galaxy Life in a Supercluster Dark Matter and Galaxy Life in a Supercluster

By means of gravitational lensing, recent Hubble observations of Abell 901/902 have helped to "illuminate" invisible dark matter and the large cosmic "web" in which it entangles "normal" matter.
