Rosetta Orbiter Sensor Sniffs the Fumes of Comet Churyumov-Gerasimenko

Rosetta Orbiter Sensor Sniffs the Fumes of Comet Churyumov-Gerasimenko

How does a comet smell? Since early August the Rosetta Orbiter Sensor for Ion and Neutral Analysis (ROSINA) is sniffing the fumes of the comet Churyumov-Gerasimenko with its two mass spectrometers. The detected chemistry in the coma of the comet is surprisingly rich already at more than 400 million kilometres from the Sun. [More]
Simulations and Analytical Studies of Travel by Single Quantum Particles

Simulations and Analytical Studies of Travel by Single Quantum Particles

Simulating the behavior of a single particle can be quite a challenging task in physics; after all, it is microscopic and we usually cannot watch in real time. It becomes even more complicated when you realize that the particle has to follow the laws of quantum physics, which allow it be in two or more places at the same time through a phenomenon called superposition.

New Experiment Tests Foundations of Quantum Mechanics at the Large Scale

University of Southampton scientists have designed a new experiment to test the foundations of quantum mechanics at the large scale. [More]
Black Hole Takes a Bite Out of a Star

Black Hole Takes a Bite Out of a Star

Astronomers have gotten the closest look yet at what happens when a black hole takes a bite out of a star—and the star lives to tell the tale. [More]
Astronomers Discover Two Families of Exocomets Orbiting Beta Pictoris Star

Astronomers Discover Two Families of Exocomets Orbiting Beta Pictoris Star

Beta Pictoris is a young star located about 63 light-years from the Sun. It is only about 20 million years old and is surrounded by a huge disc of material — a very active young planetary system where gas and dust are produced by the evaporation of comets and the collisions of asteroids. [More]
Researchers Observe East-to-West Variations in Titan’s Atmospheric Gases

Researchers Observe East-to-West Variations in Titan’s Atmospheric Gases

New maps of Saturn’s moon Titan reveal large patches of trace gases shining brightly near the north and south poles. These regions are curiously shifted off the poles, to the east or west, so that dawn is breaking over the southern region while dusk is falling over the northern one. [More]
New Observational Strategy Helps Determine Amount of Molecular Hydrogen in Distant Galaxies

New Observational Strategy Helps Determine Amount of Molecular Hydrogen in Distant Galaxies

Scientists at the Universities of Bonn and Cardiff see good times approaching for astrophysicists after hatching a new observational strategy to distill detailed information from galaxies at the edge of the Universe. [More]
Webcast Explores Role of Quantum Mechanics in Helping Understand Universe’s Fabric of Time and Space

Webcast Explores Role of Quantum Mechanics in Helping Understand Universe’s Fabric of Time and Space

Talking about the state of his profession, Dr. Nima Arkani-Hamed recently said “I haven’t been this excited about physics in a very long time.” He’ll share why he’s so excited during his Perimeter Institute (PI) public lecture on Thursday, Nov. 6, 2014 at 7 pm EST. [More]
Massive Black Holes Can Prevent Formation of New Stars

Massive Black Holes Can Prevent Formation of New Stars

Massive black holes spewing out radio-frequency-emitting particles at near-light speed can block formation of new stars in aging galaxies, a study has found. [More]
