The discovery of large amounts of nickel in the once water-filled surface of Mars provides further evidence that the red planet may have once provided suitable conditions for life. In Neretva Vallis, an ancient channel that once carried water to the slopes of Jezero Crater, researchers found more nickel than ever before in a Martian … Read more
We may finally know what created the cosmic rhythms in the early Universe. According to information from the Hubble and James Webb Space Telescopes, the origin of free-flying photons in the early universe were small clusters of young stars that burst into life, removing the fog of smooth hydrogen that filled the interstellar space. A … Read more
As water cools, its behavior becomes more surprising from a physics point of view, and researchers looking for an explanation have discovered something new: a previously hidden “point” that appears in supercooled water that doesn’t freeze. By varying pressure and temperature, scientists can keep liquid water below the normal ice surface. Previous studies have shown … Read more
Primordial black holes (PBHs) are a very special type of black hole, thought to have formed from dense pockets of subatomic matter in the seconds after the Big Bang – and a new study reports what may be the first direct time. That may take years to prove, but the prospect is exciting. Black holes … Read more
For thousands of years, people living high in the Andes of Argentina have relied on drinking water that could make many people sick. There, arsenic naturally occurring in the volcanic rocks seeps into the groundwater, contaminating local water supplies with levels of the toxic metalloid that can pose serious health risks to many people. But … Read more
