The Haystack 37m Telescope has been a landmark in radio astronomy and radar studies of the solar system since its first light in 1964. Over the following four decades, it supported NASA's Apollo landings on the moon, made ...
One of the most puzzling findings from the JWST's observations of the early universe is the size of black holes. According to our understanding of black hole growth, these early black holes are far more massive than expected. ...
This NASA Hubble Space Telescope image reveals an enigmatic galaxy with a bright center and a face that hints at spiral structure, yet it holds no obvious spiral arms. Reddish-brown clumps and filaments of dust partially ...
Astronomers may have found an explanation for one of the biggest mysteries revealed by the James Webb Space Telescope (JWST): why so many galaxies in the early universe appear unexpectedly bright in ultraviolet light. The ...
Astronomers have tracked a dramatic "changing-look" active galactic nucleus (AGN) whose central supermassive black hole appeared to switch off and then rapidly reignite. The galaxy, HE 1237−2252, dimmed in X-rays by a factor ...
We may be more in the dark about dark matter than previously thought, according to a new analysis of distant galaxy clusters. Yale astrophysicist Priyamvada Natarajan, a leading theorist on the nature of black holes and dark ...
An international team of researchers has developed new stellar and supernova models to explain the mysterious elemental abundance patterns left by billions of supernova explosions around the Perseus constellation, which have ...
Images of the sleek keels, elegant planks, and dragon-headed prows of Viking longships have been reproduced countless times on postcards, book covers, souvenirs and in television shows and movies.
Researchers have developed a technique to analyze how black holes "ring" when they collide and merge: one of the universe's most dramatic events. When black holes merge, the collision produces a new, larger black hole that ...
Astronomers led by the Center for Astrophysics | Harvard & Smithsonian (CfA) have made the first direct detection of turbulence distorting light in the interstellar medium. The findings will help scientists achieve clearer ...
