SPHEREx vs. Hubble and James Webb: Key Differences

The SPHEREx space telescope, while often compared to its predecessors Hubble and James Webb, is notably distinct in its function and objectives. Hubble, launched in 1990, primarily aims to capture high-resolution images of the cosmos, enabling detailed observation of phenomena such as nebulae and supernovae. It operates primarily in the visible, ultraviolet, and near-infrared spectra. On the other hand, James Webb — often called the successor to Hubble — was designed to observe in longer wavelengths of light, focusing on near-infrared to mid-infrared. This capacity allows it to see through dust clouds and uncover stars and planets that were once hidden [1](https://news.yahoo.com/news/nasa-spherex-space-telescope-captured-142034890.html).

SPHEREx, or Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer, was launched with a unique mission to create a comprehensive 3D map of the entire sky. Unlike James Webb, which focuses on detailed views of specific astronomical features, SPHEREx is tasked with a wide survey approach. It captures over 3,600 images daily to construct a vast digital sky map. This approach complements the work of both Hubble and James Webb by identifying new celestial phenomena and galaxies for further detailed study by these telescopes [1](https://news.yahoo.com/news/nasa-spherex-space-telescope-captured-142034890.html).

Another critical difference lies in SPHEREx's use of spectroscopy to determine the distances to galaxies far beyond the reach of the older telescopes. It aims to measure the distances to 450 million galaxies, thereby offering an unprecedented look into the universe's structure and history. SPHEREx’s ability to search for frozen water ice and life-essential molecules in the Milky Way sets it apart as it hints at astrobiological possibilities [1](https://news.yahoo.com/news/nasa-spherex-space-telescope-captured-142034890.html).

In terms of technological collaboration, SPHEREx represents a newer generation of international and commercial partnerships, echoing the collaborative essence seen in the development of James Webb. However, it is its pioneering open-access data policy that cements SPHEREx's contribution to both science and industry, spurring innovation in fields beyond astronomy like medical imaging and materials science [1](https://news.yahoo.com/news/nasa-spherex-space-telescope-captured-142034890.html).

Ultimately, while all three telescopes aim to expand our understanding of the universe, SPHEREx stands out for its ability to complement the capabilities of Hubble and James Webb. It brings a uniquely broad perspective that, when combined with the detailed insights from the other telescopes, promises to advance our knowledge of galaxy formation and cosmic evolution significantly [1](https://news.yahoo.com/news/nasa-spherex-space-telescope-captured-142034890.html).
