When did something like us first appear on the planet? It turns out there’s remarkably little agreement on this question.
The agency announced it is buying lunar soil from a commercial provider as part of a technology development program
For tens of thousands of years, a Neanderthal molar rested in a shallow grave on the floor of the Stajnia Cave in what is now Poland. For all that time, viable mitochondrial DNA remained locked inside – and now, finally, scientists are discovering its secrets.
The mysterious dark vacuum of interstellar space is finally being revealed by two intrepid spacecraft that have become the first human-made objects to leave our Solar System.
Darwin would be delighted by the story his successors have revealed
On a fine scale, the Universe seems lumpier than it should be.
A 13-million-year-old fossil unearthed in northern India comes from a newly discovered ape, the earliest known ancestor of the modern-day gibbon. The discovery by Christopher C. Gilbert, Hunter College, fills a major void in the ape fossil record and provides important new evidence about when the ancestors of today’s gibbon migrated to Asia from Africa.
Astronomers from NSF’s National Solar Observatory (NSO) will play important roles in two of five concept studies recently announced by NASA. These five endeavors have each been granted $1.25 million by the Heliophysics division of NASA to investigate the feasibility of cutting-edge missions to study the Sun and its connection to Earth.
Observations by the NASA/ESA Hubble Space Telescope and the European Southern Observatory’s Very Large Telescope (VLT) in Chile have found that something may be missing from the theories of how dark matter behaves. This missing ingredient may explain why researchers have uncovered an unexpected discrepancy between observations of the dark matter concentrations in a sample of massive galaxy clusters and theoretical computer simulations of how dark matter should be distributed in clusters. The new findings indicate that some small-scale concentrations of dark matter produce lensing effects that are 10 times stronger than expected.
