Kerckhoffs principle cipher design secret key

Good encryption should stay secure even if everyone knows how it works

Kerckhoffs's principle says an encryption system should remain secure even if an attacker knows its entire design. The secret should be the key, not the method used to encrypt the data.

Stars reveal a giant black hole at our galaxy’s center

More than 100 stars have been tracked orbiting something invisible at the center of the Milky Way. Their motion shows that about 4.3 million Suns’ worth of mass is packed into an extremely small region, providing strong evidence for a supermassive black hole.

Beetles account for roughly one in four described animal species

~400,000 species

Scientists have formally described around 400,000 beetle species, making them one of the most diverse groups of animals known. That is roughly a quarter of described animal species, although estimates vary with taxonomic counts. Many more beetle species probably remain undiscovered. Their diversity reflects millions of years of adaptation to different foods, habitats and ecological roles.
