Could a gravitational wave rip apart an entire planet?

When we detect gravitational waves, it’s because they are warping space and time by a tiny amount – but this episode of Dead Planets Society is about making one that is far more powerful

A new image of a supermassive black hole has revealed more of the disc of matter falling into it and the powerful winds created by that process. The black hole in question is called M87*, and it was the subject of the first direct image of a black hole ? this new data will help researchers complete the picture.

Artwork of the young Earth-Moon system. The Earth had recently formed when it was struck by a protoplanet called Theia roughly three times the size of Mars. Debris from the impact went into orbit, while the cores of the two planets merged. Within weeks of the event, the debris formed a Saturn-like ring around the Earth. Later collisions in this ring led to the formation of the Moon, probably within just a few thousand years. Initially the Earth and Moon were much closer together than they are now, and spinning more quickly.

Newborn stars, hidden behind thick dust, are revealed in this image of a section of the so-called Christmas Tree Cluster from NASA's Spitzer Space Telescope. The newly revealed infant stars appear as pink and red specks toward the center and appear to have formed in regularly spaced intervals along linear structures in a configuration that resembles the spokes of a wheel or the pattern of a snowflake. Hence, astronomers have nicknamed this the
