Vast swarms of hidden galaxies may be secretly bathing the universe in a soft glow

April 17, 2025 NeRD

A secret population of hidden galaxies suffusing the universe in a soft glow of far-infrared light have been strongly suggested to exist, based on careful detective work into some of the most unique data to come from Europe’s Herschel Space Observatory. The galaxies, if they are real, are not necessarily a surprise. The cosmos is filled with light across all wavelengths — it’s just that the far-infrared component seems to be stronger than can be accounted for by all the galaxies we can see in visible light. In other words,…

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

April 1, 2025 NeRD

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

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…
