The Turducken of the Cosmos

Black Hole Wormhole - Deposit Photo

Astronomers think they might be able to detect black holes falling into wormholes using ripples in spacetime known as gravitational waves, but only if wormholes actually exist and such a scenario ever happened, a new study finds. According to Einstein, who first predicted the existence of gravitational waves in 1916, gravity results from the way in which mass warps space and time. When two or more objects move within a gravitational field, they produce gravitational waves that travel at the speed of light, stretching and squeezing space-time along the way. Gravitational waves are extraordinarily difficult to detect because they are … Read more

SPACE: Hoag's Object Is The Turducken Of Galaxies

Look closely at the serpent constellation slithering through the northern sky, and you might see a galaxy within a galaxy within a galaxy. This cosmic turducken is known as Hoag’s object, and it has befuddled stargazers since astronomer Arthur Hoag discovered it in 1950. The object in question is a rare, ring-shaped galaxy measuring some 100,000 light-years across (slightly larger than the Milky Way) and located 600 million light-years from Earth. In a recent image of the oddball object taken by the Hubble Space Telescope and processed by geophysicist Benoit Blanco, a bright ring of billions of blue stars forms … Read more
