A team of astronomers led by Prof. Judd Bowman of Arizona State University unexpectedly stumbled upon “dark matter,” the most mysterious building block of outer space, while attempting to detect the earliest stars in the universe through radio wave signals, according to a study published this week in Nature.

The idea that these signals implicate dark matter is based on a second Nature paper published this week, by Prof. Rennan Barkana of Tel Aviv University, which suggests that the signal is proof of interactions between normal matter and dark matter in the early universe. According to Prof. Barkana, the discovery offers the first direct proof that dark matter exists and that it is composed of low-mass particles.

In a few months, astronomers are going to be pointing their telescopes to Sagittarius A*, the supermassive black hole at the centre of our galaxy.

That’s because it’s going to be buzzed by a closely orbiting star — providing another context for testing Einstein’s theory of general relativity.

Physicists have confirmed the existence of a new form of atomic nuclei, and the fact that it’s not symmetrical challenges the fundamental theories of physics that explain our Universe.

But that’s not as bad as it sounds, because the 2016 discovery could help scientists solve one of the biggest mysteries in theoretical physics — where is all the dark matter? — and could also explain why travelling backwards in time might actually be impossible.

Black holes don’t just sit there munching away constantly on the space around them. Eventually they run out of nearby matter and go quiet, lying in wait until a stray bit of gas passes by.

Then a black hole devours again, belching out a giant jet of particles. And now scientists have captured one doing so not once, but twice — the first time this has been observed.

Antimatter is notoriously tricky to store and study, thanks to the fact that it will vanish in a burst of energy if it so much as touches regular matter. The CERN lab is one of the only places in the world that can readily produce the stuff, but getting it into the hands of the scientists who want to study it is another matter (pun not intended). After all, how can you transport something that will annihilate any physical container you place it in? Now, CERN researchers are planning to trap and truck antimatter from one facility to another.

Antimatter is basically the evil twin of normal matter. Each antimatter particle is identical to its ordinary counterpart in almost every way, except it carries the opposite charge, leading the two to destroy each other if they come into contact. Neutron stars and jets of plasma from black holes may be natural sources, and it even seems to be formed in the Earth’s atmosphere with every bolt of lightning.

Astronomers rarely see the beginnings of these explosions, but an Argentine amateur’s lucky picture helped them study the start of a massive star’s violent death.
