This is the first image of Sagittarius A * (Sgr A *), the supermassive black hole at the center of our galaxy, captured by the Event Horizon Telescope (EHT). It is the first direct visual evidence of the presence of this black hole. Credit: EHT Collaboration Astronomers reveal the first image of the[{” attribute=””>black hole … Read more
Astronomers have uncovered a star, called HD 222925, that has the widest range of elements yet observed in a star beyond our own Sun. They have identified 65 elements in the star, including 42 from the bottom of the periodic table. A team of astronomers led by University of Michigan Ian Roederer and including Carnegie’s … Read more
Sagittarius A *. Credit: EHT Collaboration / ESO. Black holes are among the most profound predictions of Einstein’s theory of general relativity. Originally studied as a mere mathematical consequence of the theory rather than as physically relevant objects, they soon became thought of as generic and sometimes inevitable outcomes of the gravitational collapse that initially … Read more

By SETH BORENSTEIN, AP Science Writer WASHINGTON (AP) – The world’s first image of the chaotic supermassive black hole at the center of our Milky Way galaxy does not portray a voracious cosmic destroyer but what astronomers Thursday called a “gentle giant” on a near-starvation diet. Astronomers believe nearly all galaxies, including our own, have … Read more
First image of Sagittarius A *, the black hole at the center of the Milky Way galaxy. Credit: EHT Collaboration. Black holes are invisible by nature. Their pull is inescapable, forever trapping any light that falls into their gravitational abyss. But just beyond a black hole’s point of no return, light persists, and its patterns, … Read more
Three years ago, scientists used a telescope the size of Earth to produce the first-ever image of a black hole. Now, they’ve done it again – this time, closer to home, and of a very different invisible behemoth. The Event Horizon Telescope (EHT) has now produced images of two supermassive black holes: the one in … Read more
Astronomers announced on Thursday that they had pierced the veil of darkness and dust at the center of our Milky Way galaxy to capture the first picture of “the gentle giant” dwelling there: a supermassive black hole, a trapdoor in space-time through which the equivalent of four million suns have been dispatched to eternity, leaving … Read more
This illustration is an artist’s impression of the thin, rocky debris disc discovered around the two Hyades white dwarfs. Rocky asteroids are thought to have been perturbed by planets within the system and diverted inwards towards the star, where they broke up, circled into a debris ring, and were then dragged onto the star itself. … Read more
