Liquid water could have carved out Mars’ famous gullies

Image

US researchers believe that the mysterious gullies on Mars could have been carved by liquid water that formed when the planet was tilted more on its axis. During these periods, increased solar radiation vaporized carbon dioxide at the planet’s poles, raising atmospheric pressure and allowing liquid water to form.1 Mars has ice at each pole … Read more

The first view of the Milky Way seen through neutrino particles

The first view of the Milky Way seen through neutrino particles

Data collected by an Antarctic observatory has produced our first view of the Milky Way galaxy through the lens of neutrino particles. This is the first time that our galaxy has been “colored” by a particle rather than different wavelengths of light. The result, published in Science, gives researchers a new window into space. Neutrinos … Read more

New experiment reveals how ultrafast conversion of urea progresses – key to life’s origins found

Ludger Inhester, DESY

How did life begin on Earth? Specialists have long been fascinated by this question and have come up with various theories over the years.
