There are many things in the universe that we do not yet understand. Among them, the "black hole" is a particularly ...

A star cataloged as S301 is now the fastest object ever clocked orbiting the Milky Way’s central black hole, reaching speeds of 25,000 kilometers per second as it swings through its closest approach ...

"Black-hole approach" conditions, caused by inadequate runway and surrounding cultural lighting, create an optical illusion making pilots perceive themselves as higher than they are, risking premature ...

A new theoretical study suggests that the supermassive black hole at the center of the Milky Way could accelerate particles ...

If you want to understand the origins of black holes, Yale astronomers say, you need to look beyond the centers of galaxies and start searching in the nooks and crannies. That's where you'll find the ...

Using a powerful mathematical tool, scientists have unveiled the intricate "ringing" of black holes, unlocking patterns missed for decades and laying the groundwork for sharper gravitational wave ...

Astronomers have created a comprehensive census of active galactic nuclei (AGN) — galaxies powered by a feeding central black hole. The new census, led by data pipeline developer Mugdha Polimera at ...

Sgr A* is the name we’ve given to the supermassive black hole that sits at the center of the Milky Way. We’ve known about its presence since the 1970s but only managed to image it within the past few ...

When two black holes crash together and merge, the newly formed black hole rings like a bell, sending out gravitational waves with specific frequencies that fade over time. This brief, fading pattern ...

ストレンジ物質のように「ブラックホールに吸い込まれて終わり」というありきたりな結末を拒み、一波乱起こし得る理論物理学上の「対ブラックホール・ダークホース」は、実はいくつか存在します。 物理学の数式（特に一般相対性理論や量子場理論の極限）に現れる、極めて異質な4つの候補を紹介します。 1. エキゾチック物質（負の質量・負のエネルギー） 【真の天敵：ブラックホールを「縮小・消去」する刺客】 通常の物質 ...
