393,044 km / h: the Parker probe is the fastest man-made object

Nasa’s Parker Solar Probe has just broken the record for the fastest man-made object closest to the Sun that it had established. Launched in August 2018 by NASA, the Parker Solar Probe probe is designed to study the Sun's crown by approaching at a distance of less than 7 million kilometers....

Russian satellite appears to be tracking US spy satellite in Earth orbit

A Russian satellite uncomfortably positioned itself near an American spy satellite orbiting the Earth, which has led space trackers to speculate that the foreign vehicle was doing its own spying. The Russian spacecraft is supposed to inspect other satellites, and experts from the space community...

Artificial intelligence lights up black hole fusion

A simulation using an artificial intelligence algorithm succeeds in predicting the characteristics of the fusion of two black holes. Nearly five years after the discovery of the first gravitational wave in September 2015, a team from the Center for Theoretical Astrophysics of the California...

Does the merge of black holes lead to a loss of information?

In 1976, following his work on black holes, Stephen Hawking raises a paradox: according to general relativity, the information absorbed by a black hole is lost when it evaporates. However, the laws of quantum mechanics impose a conservation of information. In the same way, when two black holes merge,...
