NASA’s SPHEREx: The Cosmic Mapmaker Set to Revolutionize Our View of the Universe
in the ever-expanding quest to unravel the mysteries of the cosmos, NASA is poised to launch its newest space telescope, SPHEREx, on February 27, 2025, from the Vandenberg Space Force Base. This groundbreaking mission,developed by the NASA jet Propulsion Laboratory (JPL),promises to deliver a panoramic view of the universe,complementing the achievements of the James Webb Space Telescope (JWST) and other iconic observatories like Hubble.

SPHEREx, short for Spectro-photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer, is designed to map the cosmos in unprecedented detail. Unlike the James Webb Space Telescope, which focuses on high-resolution snapshots of specific celestial objects, SPHEREx will capture the entire sky in 102 infrared colors, creating a extensive map of the universe.
“this is the first time in human history we will see the universe in such high color resolution,” said Nicky Fox, NASA’s deputy director, in an interview with Space.com. “And we will see it every six months.”
Unveiling the Secrets of the Universe
Over its two-year mission, SPHEREx will collect data on more than 450 million galaxies and 100 million stars within the Milky Way. Some of these galaxies are so distant that their light has traveled 10 billion years to reach Earth. This data will help scientists explore the origins of the universe, including the phenomenon of cosmic inflation, which occurred nearly 14 billion years ago.
By mapping the large-scale distribution of matter in the universe, SPHEREx aims to reveal the “behind-the-scenes push” that drove this rapid expansion. Additionally, it will measure the collective light emitted by all galaxies, including those too faint or distant to be detected by other telescopes. This approach will provide a more comprehensive understanding of the universe’s primary light sources.
Searching for Life’s Building Blocks
SPHEREx will also focus on our own galaxy, the Milky Way, scanning star nurseries and regions where new planets might potentially be forming. It will search for water and organic molecules, the fundamental building blocks of life, offering valuable clues in the ongoing search for extraterrestrial life.
how SPHEREx Differs from the James Webb Telescope
While both telescopes are infrared observatories, their missions are distinct. Chin Domagal-Goldman, acting director of NASA Headquarters, likened the James Webb Space Telescope to taking a snapshot of a single person, while SPHEREx is akin to capturing a panoramic view of a crowd.The $10 billion James Webb Telescope excels in observing specific nebulae and narrow fields with extreme precision. In contrast, SPHEREx’s goal is to provide a full-sky map, enabling scientists to identify targets for further study by more powerful telescopes like Hubble and Webb.
A New Era in Space Exploration
SPHEREx’s unique cone-shaped design allows it to maintain ultra-low temperatures, essential for detecting faint infrared signals. Its detectors operate at approximately minus 350 degrees Fahrenheit (about 210 degrees Celsius), ensuring optimal performance.
This mission adds a new dimension to NASA’s arsenal of space telescopes. While Hubble and Webb have revealed stunning details of planets, stars, and galaxies, SPHEREx will answer broader questions, such as the total light emitted by all galaxies in the universe.
Key Comparisons: SPHEREx vs. James Webb Telescope

Editor’s Interview with NASA’s Nicky Fox on SPHEREx
Editor: Nicky, thank you for joining us today. Can you start by explaining what makes SPHEREx so unique compared to other space telescopes like the James Webb Space Telescope?
Nicky Fox: Absolutely! SPHEREx, or the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer, is designed to take a panoramic view of the cosmos. Unlike the James Webb Space Telescope, which focuses on detailed snapshots of specific celestial objects, SPHEREx will map the entire sky in 102 infrared colors. This will give us an unprecedented, high-resolution picture of the universe every six months.
Editor: That sounds unbelievable. What do you hope to discover with this mission?
Nicky Fox: SPHEREx will collect data on over 450 million galaxies and 100 million stars within the Milky Way. Some of these galaxies are so far away that their light has traveled 10 billion years to reach us. This will help us explore the origins of the universe, including cosmic inflation that occurred nearly 14 billion years ago. Additionally, SPHEREx will search for water and organic molecules in star nurseries, providing clues about the building blocks of life.
Editor: How does SPHEREx’s infrared technology differ from other telescopes?
Nicky Fox: SPHEREx’s detectors operate at ultra-low temperatures, around minus 350 degrees Fahrenheit, which is critical for detecting faint infrared signals. While the James webb Telescope excels in detailed observations of specific targets, SPHEREx provides a full-sky map.This will help scientists identify new targets for future missions with telescopes like Hubble and Webb.
Editor: How will SPHEREx contribute to our understanding of the universe’s expansion?
Nicky Fox: By mapping the large-scale distribution of matter, SPHEREx will reveal the forces behind the rapid expansion of the universe. It will also measure the collective light emitted by all galaxies, including those too faint or distant for other telescopes to detect. This will give us a more complete understanding of the universe’s primary light sources.
Editor: What excites you the most about this mission?
Nicky fox: What excites me is the sheer scale of what SPHEREx will accomplish. For the first time, we’ll have a full-sky map in such high color resolution. This will not only guide future missions but also deepen our understanding of cosmic history and the origins of life. It’s a monumental step forward in our quest to unravel the mysteries of the universe.
Editor: when can we expect to start seeing results from SPHEREx?
Nicky Fox: SPHEREx is set to launch on February 27, 2025, from the Vandenberg Space Force Base. Once operational, we’ll start receiving data within months. I encourage everyone to stay tuned for updates on this groundbreaking mission.
Editor: Thank you, Nicky, for sharing these insights.We’re all looking forward to the discoveries SPHEREx will bring.
