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…

Rare string of ‘cosmic pearls’ dance together in the universe

January 3, 2025 NeRD

Astronomers have discovered a rare group of five dwarf galaxies located relatively close to Earth; these galaxies exist in a near-perfect alignment, resembling a string of cosmic pearls in the sky. Held together by their mutual gravity, several of the dwarf galaxies (designated D1 to D5) are rhythmically dancing with one another while others are engaged in a “cosmic tug of war,” ripping gas and stars away from each other. The scientists behind this discovery say these factors make this dwarf galaxy grouping particularly intriguing. The arrangement may be as…

Ancient cosmic collisions may have birthed the universe’s most monstrous galaxies

December 8, 2024 NeRD

Astronomers have discovered that large flows of cold gas created by collisions between galaxies in the early universe may have forged some of the most monstrous star systems. The formation of ancient gigantic galaxies that bulge like footballs compared to our relatively flat spiral galaxy, the Milky Way, has confused astronomers for decades. Now, a team led by scientists from the University of Southampton may have scored a touchdown in this quest. They believe their research may finally solve this long-standing galactic puzzle. “Two disk galaxies smashing together caused gas…
