An international team of astronomers led by researchers from the Netherlands has found no trace of dark matter in the galaxy AGC 114905, despite taking detailed measurements over a course of forty hours with state-of-the-art telescopes. They will present their findings in Monthly Notices of the Royal Astronomical Society.

When Pavel Mancera Piña (University of Groningen and ASTRON, the Netherlands) and his colleagues discovered six galaxies with little to no dark matter, they were told “measure again, you’ll see that there will be dark matter around your galaxy”...

Scientists reveal conditions in early solar system. Ever since scientists started looking at meteorites with microscopes, they’ve been puzzled — and fascinated — by what’s inside. Most meteorites are made of tiny beads of glass that date back to the earliest days of the solar system, before the planets were even formed.

The boiling new world, which zips around its star at ultraclose range, is among the lightest exoplanets found to date. The TESS mission has discovered an ultra-short-period planet (USP) that is also super light. The planet is named GJ 367 b, and it orbits its star in just eight hours. The planet is about the size of Mars, and half as massive as the Earth, making it one of the lightest planets discovered to date.

Ultra-short-period planets are small, compact worlds that whip around their stars at close range, completing an orbit — and a single, scorching year — in less than 24 hours...
