And if there is life out in space, scientists may one day use this same technique to detect its biosignature — the telltale chemical signs of its presence — in…
In physics, there's small, and then there's nullity – as in zero-dimensional.
On March 5 at 1500 UTC/10 a.m. EST, Tropical Cyclone Faxai's center was located near 22.5 south and 155.2 east, about 699 nautical miles/804.4 miles/ 1,295 km…
Atomic force microscopy is a method normally used for imaging matter with very high resolution. The sharp tip of the microscope is used to scan the surface…
Sixteen years ago two teams of supernova hunters, one led by Saul Perlmutter of the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley…
A team of scientists around Dr. Nathalie Picqué and Prof. Theodor W. Hänsch at the Laser Spectroscopy Division of the Max Planck Institute of Quantum Optics…
A bright supernova discovered only six weeks ago in a nearby galaxy is provoking new questions about the exploding stars that scientists use as their main…
At a distance of approximately 11.5 million light-years from Earth it is the closest supernova of its type discovered in the past few decades. The explosion…
A Chinese-U.S. research team is exploring the use of metamaterials — artificial materials engineered to have exotic properties not found in nature — to…
An intense light pulse interacting with a weakly bound van der Waals cluster consisting of thousands of atoms can eventually lead to the explosion of the…
The giant explosions, called hot flow anomalies, can be so large at Venus that they’re bigger than the entire planet and they can happen multiple times a day.”Not only are they gigantic,” said Glyn Collinson, a space scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md. “But as Venus doesn’t have a magnetic field to protect itself, the hot flow anomalies happen right on top of the planet. They could swallow the planet whole.”…
The technique—building an array of tiny pillars on top of a sheet of thermoelectric material—represents an entirely new way of attacking a century-old problem,…
In a paper published this week in the journal Physical Review Letters, MIT researchers propose an experiment that may close the last major loophole of Bell's…
Using NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) — a high-energy X-ray observatory — the international collaboration created the first-ever map of…
Using data from NASA's Rossi X-ray Timing Explorer (RXTE) satellite, an international team has uncovered a dozen instances where X-ray signals from active…
Existing procedures to generate these, however, lead to results occurring more by chance in view of the number of photon pairs in one pulse. The consequences…
