Astronomers have discovered the absence of an unstable massive star in a dwarf galaxy. Scientists think this could indicate that the star became less bright and partially obscured by dust. An alternative explanation is that the star collapsed into a black hole without producing a supernova.

In a new study of axion motion, researchers propose a scenario known as 'kinetic misalignment' that greatly strengthens the case for axion/dark matter equivalence. The novel concept answers key questions related to the origins of dark matter and provides new avenues for ongoing detection efforts.

The young star HBC 672 is known by its nickname of Bat Shadow because of its wing-like shadow feature. The NASA/ESA Hubble Space Telescope has now observed a curious 'flapping' motion in the shadow of the star's disc for the first time.

An interdisciplinary team of scientists has demonstrated that it is possible to build an ultra-sensitive sensor based on a new fluorescent molecule able to detect the nuclear decay key to knowing whether or not a neutrino is its own antiparticle. The results of this study have great potential to determine the nature of the neutrino and thus answer fundamental questions about the origin of the Universe.

Researchers have found that rocky exoplanets, which formed early in the life of the galaxy seem to have had a greater chance of developing a magnetic field and plate tectonics than planets, which formed later. This means that if life exists in the Galaxy, it may have developed earlier than later, and that planets formed more recently may have less chance of developing life.

Earth's Moon has a 'near side' that is perpetually Earth-facing and a 'far side', which always faces away from Earth. The composition of the Moon's near side is oddly different from its far side, and scientists think they finally understand why.

Through a mathematical analysis of several dozen exoplanets, scientists learned something significant: More than a quarter of the exoplanets they studied could be ocean worlds, with a majority possibly harboring oceans beneath layers of surface ice, similar to Europa and Enceladus.

As nuclear fusion engines, most stars live placid lives for hundreds of millions to billions of years. But near the end of their lives they can turn into crazy whirligigs, puffing off shells and jets of hot gas. Hubble has dissected such crazy fireworks in two nearby young planetary nebulas.
