A study has found that some dwarf galaxies may today appear to be dark-matter free even though they formed as galaxies dominated by dark matter in the past.

Betelgeuse is normally one of the brightest, most recognizable stars of the winter sky, marking the left shoulder of the constellation Orion. But lately, it has been behaving strangely: an unprecedentedly large drop in its brightness has been observed in early 2020, which has prompted speculation that Betelgeuse may be about to explode.

Astronomers have just observed bizarre, never-seen-before behaviour from a 'radio-loud' magnetar - a rare type of neutron star and one of the strongest magnets in the Universe. Their new findings suggest magnetars have more complex magnetic fields than previously thought - which may challenge theories of how they are born and evolve over time.

A new type of rocket thruster that could take humankind to Mars and beyond has been proposed by a physicist. The device would apply magnetic fields to cause particles of plasma to shoot out the back of a rocket and propel the craft forward.

Faint light from rogue stars not bound to galaxies has been something of a mystery to scientists. The dimness of this intracluster light makes it difficult to measure, and no one knows how much there is. Scientists have made the most radially extended measurement of this light ever, and they've found that its distribution might point to the distribution of dark matter.

Why are the planets of the inner Solar System dry and rocky, but the outer ones are not? Researchers discovered that a two-step formation process of the planets can explain the chronology and split in volatiles like water and isotope content of the inner and outer Solar System.

Far below the gaseous atmospheric shroud on Saturn?s largest moon, Titan, lies Kraken Mare, a sea of liquid methane. Astronomers have estimated that sea to be at least 1,000-feet deep near its center - enough room for a potential robotic submarine to explore.
