Salad in space? New research says it’s not a healthy choice. It’s been more than three years since the National Aeronautics and Space Administration made space-grown lettuce an item on the menu for astronauts aboard the International Space Station. Alongside their space diet staples of flour tortillas and powdered coffee, astronauts can munch on a salad, grown from control chambers aboard the ISS that account for the ideal temperature, amount of water and light that plants need to mature.

But there is a problem...

Lightest Black Hole or Heaviest Neutron Star? MeerKAT Uncovers a Mysterious Object in Milky Way

An international team of astronomers have found a new and unknown object in the Milky Way that is heavier than the heaviest neutron stars known and yet simultaneously lighter than the lightest black holes known.

Using the MeerKAT Radio Telescope, astronomers from a number of institutions including The University of Manchester and the Max Planck Institute for Radio Astronomy in Germany found an object in orbit around a rapidly spinning millisecond pulsar located around 40,000 ligh...

Mars Express finds Evidence of Large Water Deposit at the Medusae Fossae Formation

Windswept piles of dust, or layers of ice? ESA’s Mars Express has revisited one of Mars’s most mysterious features to clarify its composition. Its findings suggest layers of water ice stretching several kilometers below ground—the most water ever found in this part of the planet.

Over 15 years ago, Mars Express studied the Medusae Fossae Formation (MFF), revealing massive deposits up to 2.5 km deep. From these early observations, it was unclear what the deposits were made of—but new research now has an answer.

“We’ve explored the MFF again using newer data from Mars Express’s M...

Moon Rocks with Unique Dust found

The meter-high rocks discovered in the work are located near the Reiner K crater in the “Reiner Gamma” region, which has a magnetic anomaly.

The moon is almost completely covered in dust. Unlike on Earth, this dust is not smoothed by wind and weather, but is sharp-edged and also electrostatically charged. This dust has been studied since the Apollo era at the end of the 1960s. Now, an international research team led by Dr. Ottaviano Rüsch from the University of Münster has for the first time discovered anomalous meter-sized rocks on the lunar surface that are covered in dust and presumably exhibit unique properties—such as magnetic anomalies.

The scientists’ most important finding is that only very few boulders on the moon have a layer of dust with very special reflective proper...
