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

March 7, 2025 NeRD

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…

Astronomers discover misshapen galaxy is a cosmic predator that bears ‘scars’ from its last meal (photo)

February 23, 2025 NeRD

An unusual elliptical galaxy with a history of absorbing smaller galaxies appears to be approaching its next target. New images from the Very Large Telescope (VLT) at the European Southern Observatory’s (ESO) Paranal Observatory suggest that the galaxy, known as NGC 3640, may soon merge with a smaller galactic companion. Located 88 million light-years from Earth, NGC 3640 belongs to a group of galaxies that range in shape and size, including its own unusual oval or egg shape. The VLT images revealed that NGC 3640 has eaten other galaxies over…

Astronomers discover ‘Quipu,’ the single largest structure in the known universe

February 22, 2025 NeRD

Astronomers have discovered what may be the largest-scale structure in the known universe — a group of galaxy clusters and clusters of galaxy clusters that spans roughly 1.3 billion light-years across and contains a mind-boggling 200 quadrillion solar masses. The newfound structure is dubbed Quipu after an Incan system of counting and storing numbers using knots on cords. Like a Quipu cord, the structure is complex, made up of one long filament and multiple side filaments. It spans roughly 1.3 billion light-years (more than 13,000 times the length of the…

Bullseye!

February 4, 2025 NeRD

NASA, ESA, CSA, and STScI This image from NASA’s Hubble Space Telescope, released on Feb. 4, 2025, shows the gargantuan galaxy LEDA 1313424, aptly nicknamed the Bullseye. A far smaller blue dwarf galaxy went through the Bullseye’s center, leaving nine star-filled rings. Astronomers using Hubble identified eight visible rings, more than previously detected by any telescope in any galaxy, and confirmed a ninth using data from the W. M. Keck Observatory in Hawaii. Previous observations of other galaxies show a maximum of two or three rings. Hubble and Keck’s follow-up observations…

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

January 31, 2025 NeRD

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…
