What happens inside a black hole stays inside a black hole, but what happens inside a black hole’s “sphere of influence” – the innermost region of a galaxy where a black hole’s gravity is the dominant force – is of intense interest to astronomers and can help determine the mass of a black hole as well as its impact on its galactic neighborhood.

Vast interstellar events where clouds of charged matter hurtle into each other and spew out high-energy particles have now been reproduced in the lab with high fidelity. The work, by MIT researchers and an international team of colleagues, should help resolve longstanding disputes over exactly what takes place in these gigantic shocks.

NASA is building a system to send astronauts to the Moon for Artemis missions, and that includes tests to make sure the Orion spacecraft is prepared to safely carry crew on an alternate mission profile in the face of unexpected problems. That capability was most recently demonstrated with a successful, continuous 12-minute firing of Orion's propulsion system that simulated a possible alternate mission scenario.

This image shows a snippet of the Sun up close, revealing a golden surface marked by a number of dark, blotchy sunspots, curving filaments, and lighter patches known as ‘plages’ – brighter regions often found near sunspots. The width of the image would cover roughly a third of the diameter of the solar disc.

On 25 July, an asteroid the size of a football field flew by Earth, coming within 65 000 km of our planet’s surface during its closest approach – about one fifth of the distance to the Moon. The 100 m-wide asteroid dubbed '2019 OK' was detected just days before it passed Earth, although archival records from sky surveys show it had previously been observed but wasn't recognised as a near-Earth asteroid.

A piping hot planet discovered by NASA’s Transiting Exoplanet Survey Satellite (TESS) has pointed the way to additional worlds orbiting the same star, one of which is located in the star’s habitable zone. If made of rock, this planet may be around twice Earth’s size.

NASA’s newest planet hunter, the Transiting Exoplanet Survey Satellite (TESS), has discovered three new worlds — one slightly larger than Earth and two of a type not found in our solar system — orbiting a nearby star. The planets straddle an observed gap in the sizes of known planets and promise to be among the most curious targets for future studies.
