Scientists have detected emanating from the nucleus of a galaxy relatively close to our Milky Way flashes of X-rays gradually ...

though not as dense as a black hole. Stars with up to eight times the mass of our sun appear destined to end up as a white dwarf. They eventually burn up all the hydrogen they use as fuel. Gravity ...

Using the XMM-Newton X-ray telescope, astronomers have witnessed a supermassive black hole already noted for its mysterious behavior demonstrating another strange phenomenon. The Massachusetts ...

These petite shrubs are perfect for pots and patio gardens. Think small with the top picks for dwarf container shrubs.

Gravity then causes them to collapse and blow off their outer layers in a “red giant” stage ... as the white dwarf was drawn ever closer to the black hole and the size of its orbit diminished ...

X-ray oscillations linked to black hole 1ES 1927+654 White dwarf orbits close to the black hole, preventing fall XMM-Newton detects X-ray flashes, hinting at gravitational waves ...

Researchers have discovered that black holes engage in a cosmic dance and a star-lit meal to vibe with each other in a cosmic ...

Rather than succumbing to star-shredding tidal forces, such a white dwarf would instead trickle-feed a small fraction of its matter to the black hole. This could offset the orbital energy being ...

Supermassive black hole reactivates, emitting plasma jets New data sheds light on black hole’s unusual behavior since 2018 Potential white dwarf companion may explain black hole's activity ...
