JWST Shows Ice-Covered Pebbles Delivering Water to New Planets
The JWST has delivered a breakthrough in planetary science. Its observations show that a long-proposed theory of planet formation is true. Up until now, thick veils of dust in young solar systems have obscured the evidence.
'Peculiar' aurora-like radio signal from sunspot discovered for the 1st time
A sunspot has put on a stunning display of radio waves lasting for over a week that resembles the northern and southern lights — auroral displays that occur over Earth.
Plants Could Grow in Lunar Regolith Using Bacteria
In the next decade, NASA, China, and their international and commercial partners plan to establish habitats on the Moon. Through the Artemis Program, NASA will deploy the orbiting Lunar Gateway and the Artemis Base Camp on the lunar surface. Meanwhile, China (and its partner Roscosmos) will deploy the International Lunar Research Station (ILRS), consisting of an orbital and surface element. The creation of this infrastructure will enable a “sustained program of lunar exploration and development” that could lead to a permanent human presence there.

How Black Holes Consume Entropy
Entropy is one of those fearsomely deep concepts that form the core of entire fields of physics (in this case, thermodynamics) that is unfortunately so mathematical that it’s difficult to explain in plain language. But we will give it a try. Whenever I see the word entropy, I like to replace it with the phrase “counting the number of ways that I can rearrange a scenario while leaving it largely the same.” That’s a bit of a mouthful, I agree, and so entropy will have to do.
The Origins of the Black Hole Information Paradox
While physics tells us that information can neither be created nor destroyed (if information could be created or destroyed, then the entire raison d’etre of physics, that is to predict future events or identify the causes of existing situations, would be impossible), it does not demand that the information be accessible. For decades physicists assumed that the information that fell into a black hole is still there, still existing, just locked away from view.
