Liquid underground pools probably formed 4.6 billion years ago in the parent body of the Bennu asteroid and contain the building blocks of life, but not living creatures. This is the new chemical analysis of the samples that NASA’s Osiris-Rex mission grabbed from the spatial rock approximately 500 meters in 2020 and returned to Earth … Read more
Rivers may have operated on a global scale about 3.5 billion years ago. The new finding comes the courtesy of ancient rocks in China and South Africa. A change in rocky chemistry around that time provides the earliest known chemical evidence for the weather of the Earth’s continents and the subsequent distribution of nutrients from … Read more
A gigantic influence 3.8 billion years ago sent a rock curtain flying away from a point near the south pole of the moon. When that curtain fell, its rocks dipped up to 3.5 kilometers on the lunar surface with energy 130 times more than the global inventory of nuclear weapons, new calculations show. And this … Read more
A staccato explosion of electromagnetic energy is first followed in an old, dead galaxy. The discovery supports the idea that there are more ways to produce such flames, called rapid radio explosions, as it was originally thought. Rapid radio, or FRB distributions, are long explosions of milliseconds of intense radio waves. Astronomers have noticed thousands … Read more
A neutrino from the space recently plunged into the Mediterranean Sea with an energy that blows all other neutros known by water. Packaging a handful of about 220 million electronic volts, this particle was about 20 times more energetic than the highest cosmic neutrinos previously seen, researchers report on 13 February Nature. The particle was … Read more
