2025年2月4日 · The gargantuan galaxy LEDA 1313424 is rippling with nine star-filled rings after an “arrow” — a far smaller blue dwarf galaxy — shot through its heart. 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 ...

2025年2月7日 · The ring galaxy, nicknamed “Bullseye,” is located 567 million light-years away in the constellation Pisces. It is 250,000 light-years wide, about 2½ times the span of the Milky Way. Bullseye surprised scientists with its many star-filled rings, as previously observed collisional ring galaxies feature a maximum of two or three rings.

2025年2月8日 · About 50 million years ago, a small blue dwarf galaxy plunged through the massive Bullseye galaxy, creating a striking ripple effect. But in space, these “waves” behave differently. Instead of water, the impact pushed gas, dust, and stars both inward and outward, forming at least nine glowing rings in the larger galaxy.

2025年2月4日 · A Yale-led team of astronomers has discovered a cosmic rarity: a super-sized galaxy with nine concentric rings. Officially known as LEDA 1313424, the “Bullseye” galaxy got its rings about 50 million years ago after a much smaller galaxy collided with its midsection — like a cosmic dart landing dead center in a game of Knockout at the local pub.

Little red dots (LRDs) are a class of small, red-tinted galaxies discovered by the James Webb Space Telescope (JWST). [1][2][3] Their discovery was published in March 2024, making them poorly understood due to limited data collection. [4] .

2025年1月16日 · Just to the northeast of the Great Square of Pegasus, it appears as a spindle-shaped patch of haze with a bright center. It is the nearest galaxy to our Milky Way, the magnificent Andromeda galaxy. The faint light you are seeing left the spiral galaxy 2.5 million years ago to cross the immense gulf in intergalactic space toward Earth.
