NASA’s SPHEREx Space Telescope Begins Capturing Entire Sky

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s SPHEREx mission is observing the entire sky in 102 infrared colors, or wavelengths of light not visible to the human eye. This image shows a section of sky in one wavelength (3.29 microns), revealing a cloud of dust made of a molecule similar to soot or smoke. NASA/JPL-Caltech This image from NASA’s SPHEREx shows the same region of space in a different infrared wavelength (0.98 microns), but the dust cloud is no longer visible. The molecules that compose…

NASA’s SPHEREx Takes First Images, Preps to Study Millions of Galaxies

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s SPHEREx, which will map millions of galaxies across the entire sky, captured one of its first exposures March 27. The observatory’s six detectors each captured one of these uncalibrated images, to which visible-light colors have been added to represent infrared wavelengths. SPHEREx’s complete field of view spans the top three images; the same area of the sky is also captured in the bottom three images. NASA/JPL-Caltech Processed with rainbow hues to represent a range of infrared wavelengths, the…

Cosmic Mapmaker: NASA’s SPHEREx Space Telescope Ready to Launch

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Ahead of launch, NASA’s SPHEREx is enclosed in a payload fairing at Vandenberg Space Force Base on March 2. The observatory is stacked atop the four small satellites that make up the agency’s PUNCH mission. NASA/BAE Systems/Benjamin Fry NASA’s latest space observatory is targeting a March 8 liftoff, and the agency’s PUNCH heliophysics mission is sharing a ride. Here’s what to expect during launch and beyond. In a little over a day, NASA’s SPHEREx space telescope is slated to…

6 Things to Know About SPHEREx, NASA’s Newest Space Telescope

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s SPHEREx observatory undergoes testing at BAE Systems in Boulder, Colorado, in August 2024. Launching no earlier than Feb. 27, 2025, the mission will make the first all-sky spectroscopic survey in the near-infrared, helping to answer some of the biggest questions in astrophysics. BAE Systems/NASA/JPL-Caltech Shaped like a megaphone, the upcoming mission will map the entire sky in infrared light to answer big questions about the universe. Expected to launch no earlier than Thursday, Feb. 27, from Vandenberg Space…

SPHEREx’s Concentric Cones

Short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, SPHEREx will create a map of the cosmos like no other. Using a technique called spectroscopy to image the entire sky in 102 wavelengths of infrared light, SPHEREx will gather information about the composition of and distance to millions of galaxies and stars. With this map, scientists will study what happened in the first fraction of a second after the big bang, how galaxies formed and evolved, and the origins of water in planetary systems…

NASA to Preview Sky-Mapping Space Telescope Ahead of Launch

NASA’s SPHEREx space observatory was photographed at BAE Systems in Boulder, Colorado, in November 2024 after completing environmental testing. The spacecraft’s three concentric cones help direct heat and light away from the telescope and other components, keeping them cool. Credit: BAE Systems NASA will host a news conference at 12 p.m. EST Friday, Jan. 31, to discuss a new telescope that will improve our understanding of how the universe evolved and search for key ingredients for life in our galaxy. Agency experts will preview NASA’s SPHEREx (Spectro-Photometer for the History…

What is Dark Energy? Inside our accelerating, expanding Universe

11 min read What is Dark Energy? Inside our accelerating, expanding Universe Some 13.8 billion years ago, the universe began with a rapid expansion we call the big bang. After this initial expansion, which lasted a fraction of a second, gravity started to slow the universe down. But the cosmos wouldn’t stay this way. Nine billion years after the universe began, its expansion started to speed up, driven by an unknown force that scientists have named dark energy. But what exactly is dark energy? The short answer is: We don’t…
