The Wide Field Camera 3 (WFC3) is the Hubble Space Telescope's last and most technologically advanced instrument to take images in the visible spectrum. It was installed as a replacement for the Wide Field and Planetary Camera 2 during the first spacewalk of Space Shuttle mission STS-125 (Hubble Space Telescope Servicing Mission 4) on May 14, 2009.

The Wide Field Camera 3 (WFC3) is a fourth-generation UVIS/IR imager aboard the Hubble Space Telescope (HST). WFC3 was installed in May 2009 during HST servicing mission 4, and replaces the Wide Field Planetary Camera 2 (WFPC2).

WFC3 is greatly enhancing the observational capabilities of Hubble. Compared to its predecessor, it offers improved resolution over a wider field of view. In terms of overall performance, it offers comparable performance to the ACS instrument, but over a wider range of wavelengths.

2023年10月4日 · Hubble's Wide Field Camera 3 (WFC3) instrument. WFC3 studies a diverse range of objects and phenomena, from young and extremely distant galaxies, to much more nearby stellar systems, to objects within our very own solar system and exoplanets.

Three main drivers have inspired the current design of WFC3: (1) WFC3 must be able to offer excellent visible-band imaging performance which will endure until the end of the HST mission; (2) in order to address a wide variety of astrophysical questions and greatly expand HST’s

As Hubble enters the last stage of its life, WFC3 - Wide Field Camera 3 - will be Hubble's next evolutionary step, allowing Hubble to peer ever further into the mysteries of the cosmos. What? To ensure the imaging capabilities of Hubble, Wide Field Camera 3 (WFC3) replaced Wide Field Planetary Camera 2 (WFPC2).

Wide Field Camera 3 (WFC3) The Wide Field Camera 3 (WFC3) was installed in May 2009 during Servicing Mission 4, replacing the highly accomplished WFPC2. This camera provides ultraviolet, optical, and near-infrared imaging through two independent channels.

200 Vesey Street, formerly known as Three World Financial Center and also known as the American Express Tower, is one of four towers that comprise the Brookfield Place complex in the Financial District of Lower Manhattan in New York City. Rising 51 floors and 739 feet (225 m), it is situated between the Hudson River and the World Trade Center.
