Ancient oasis once existed on Mars
Ancient oasis once existed on Mars
New findings from the ChemCam instrument show a dynamic Martian climate LOS ALAMOS, N.M., Oct. 7, 2019-The surface of Mars was once home to shallow, salty ponds that went through episodes of overflow and drying, according to a paper published today . These findings result from an analysis of rocks enriched in mineral salts in Gale Crater, a 100-mile-wide dry lakebed, performed with the ChemCam instrument, which sits atop NASA's Curiosity rover and shoots Martian rocks with a laser to determine their chemical make-up.

Nearly a decade in the making, exoplanet-hunting instrument installed in Hawaii
Atop a dormant volcano in Hawaii, an extremely delicate instrument-designed to help scientists find distant worlds-is scattered across the floor in hundreds of pieces. "Imagine trying to assemble one of those huge LEGO sets, except there's no instruction book; you've done it once before, but then you had to take it all apart and put it in little bags," said Jacob Bean, associate professor of astronomy and astrophysics at the University of Chicago.

Quantum Vacuum: Less than Zero Energy
Quantum Vacuum: Less than Zero Energy
Is it possible to borrow energy from an empty space? And if yes, do we have to give it back? Energy values smaller than zero are allowed - at least within certain limits. Energy is a quantity that must always be positive - at least that's what our intuition tells us. If every single particle is removed from a certain volume until there is nothing left that could possibly carry energy, then a limit has been reached.

Growing old together: a sharper look at black holes and their host galaxies
Some relationships are written in the stars. That's definitely the case for supermassive black holes and their host galaxies, according to a new study from Yale University. The "special relationship" between supermassive black holes (SMBHs) and their hosts - something astronomers and physicists have observed for quite a while - can now be understood as a bond that begins early in a galaxy's formation and has a say in how both the galaxy and the SMBH at its center grow over time, the researchers note.

More accurate than expected
More accurate than expected
Despite their extremely small mass, neutrinos play a key role in cosmology and particle physics. After evaluation of the first measurement results in the Karlsruhe Tritium Neutrino Experiment (KATRIN), it is now clear: The previously unknown mass of the neutrinos must be less than 1 electron volt. This result is more accurate than previous measurements and raises hopes of discovering new neutrino properties.
