2024年8月8日 · JWST has a relatively small continuous viewing zone (CVZ), located within 5° of the ecliptic poles. The CVZ is important for some science programs that involve monitoring throughout the year and is also useful for calibration observations.

This website holds a comprehensive collection of documentation (known as JDox) on the JWST spacecraft and instruments, preparing observing proposals, and getting started on data analysis.

The JWST Observatory, as a whole, has a reference coordinate system used by operations to define the pointing of the telescope within the field of regard (FOR), including defining the continuous viewing zone (CVZ) available to the observatory. See also: JWST Position Angles, Ranges, and Offsets.

The 3-epoch JWST data (>28.5 mag) will enable time-domain science such as finding and studying core-collapse supernovae in dusty starbursts and high-z Type Ia supernovae potentially to z=6. Reaching the full scientific potential, however, requires high-resolution data in the optical bands that are either not accessible to or not optimized with ...

2018年10月29日 · JWST 's southern CVZ is dominated by the Large Magellanic Cloud (LMC) and a denser distribution of Galactic stars, rendering it less suitable for deep extragalactic surveys with JWST /NIRCam, while the northern CVZ has portions that appear relatively empty of sources that are bright at these wavelengths.

Imviz provides visualization and quick-look analysis for 2D astronomical images. This tool is designed with instrument modes from the James Webb Space Telescope (JWST) in mind, but the tool should be flexible enough to read in data from many astronomical telescopes. The documentation provides a complete table of all supported modes.

We propose ACS F435W, F606W, and F814W imaging in the IRAC Dark Field (IDF), which is in the JWST continuous viewing zone (CVZ) and will be observed by JWST GTO program #2738 in three epochs in Cycle 1 using NIRCam.

A micrometeoroid avoidance zone (MAZ), that overlaps part of the JWST field of regard, has been defined. Minimizing JWST pointings in this region will lower the risk of damage from incoming debris.

詹姆斯·韦布太空望远镜 （JWST）是一台主要用于进行红外波段观测的空间望远镜，能够通过更高红外分辨率和灵敏度，观测到相比哈勃望远镜更早、更远或更加微弱的天体。 他将在天文学及宇宙学领域展开广泛的调查，例如观测第一批恒星和行星的形成，以及系外行星大气特征等。 JWST的主镜直径为6.5米，由18个由镀金铍制成的六边形镜段结合在一起，这使JWST的采光面积约为25平方米，大约是哈勃望远镜的六倍。 JWST主要在较低的频率范围内进行观测，从长波长可见 …

詹姆斯·韦布空间望远镜（英文：James Webb Space Telescope，缩写：JWST，简称：韦布空间望远镜，），是美国航空航天局、欧洲航天局和加拿大国家航天局联合研发的红外线观测用空间望远镜，为哈勃空间望远镜的继任者。
