6 days ago · The SPHEREx space telescope will take a different approach and measure the total glow from all galaxies, including galaxies too small, too diffuse, or too distant for other telescopes to easily detect. Combining the measurement of this overall glow with other telescopes’ studies of individual galaxies will give scientists a more complete ...

Over a two-year planned mission, the SPHEREx Observatory will collect data on more than 450 million galaxies along with more than 100 million stars in the Milky Way in order to explore the origins of the universe. Launch Date: No Earlier Than February 27, 2025.

Jan 31, 2025 · The SPHEREx observatory will make the most colorful all-sky map ever. The SPHEREx observatory “sees” infrared light. Undetectable to the human eye, this range of wavelengths is ideal for studying stars and galaxies. Using a technique called spectroscopy, the telescope can split the light into its component colors (individual wavelengths ...

SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) [3] is a future near-infrared space observatory that will perform an all-sky survey to measure the near-infrared spectra of approximately 450 million galaxies.

SPHEREx relies on an entirely passive cooling system — no electricity or coolants are used, simplifying the spacecraft’s design and operational needs. Key components of this system include three cone-shaped photon shields to protect the telescope from the heat of Earth and the Sun, as well as a mirrored structure beneath the shields to ...

Jan 28, 2025 · The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) mission will provide the first all-sky spectral survey. Over a two-year planned mission, the SPHEREx Observatory will collect data on more than 450 million galaxies along with more than 100 million stars in the Milky Way in order to explore ...

SPHEREx will create spectra (0.75 – 5 um at R = 35-130) with high sensitivity using a cooled telescope with a wide field-of-view for large mapping speed. During its two-year mission, SPHEREx will produce four complete all-sky maps that will serve as a rich archive for the astronomy community.

SPHEREx will enter a polar orbit around Earth and create a 3D map of the entire sky, gathering information about millions of galaxies for scientists to study what happened after the big bang, the history of galaxy evolution, and the origins of water in planetary systems in our galaxy.

When it launches – no later than April 2025 – SPHEREx will help scientists better understand where water and other key ingredients necessary for life originated.
