How big data is fueling a new age in space exploration

A few major factors will drive exponential growth in the amount of terabytes falling on us from the skies over the next couple of decades: the increasing speed of commercial satellite deployment, implementation of faster communication technology, and the onset of interplanetary missions.

The difficulty of using the Doppler shift to measure the wobble of a star

One of the biggest advances of astronomy in the past decade has been the discovery of planets orbiting other stars, known as exoplanets. But just how many exoplanets have been discovered? According to the Extrasolar Planet Encyclopedia, a semi-official catalog based in Europe, there were as of the end of September last year 990 confirmed exoplanets and 2,321 candidate exoplanets.

Physicists succeed in compressing quantum data for the first time

if we have a system of qubits all in the same state (with the same probability distributions), we have identical qubits, even though we might get different results upon measuring the individual qubits. Strangely enough, particles in the quantum world can be both identical and distinct at the same time.  (Credit: M. Byrne)

Composite image shows two black holes orbiting each other

his composite X-ray/radio image of Abell 400 shows radio jets (pink), immersed in a vast cloud of multimillion degree X-ray emitting gas (blue) that pervades the cluster. The jets emanate from the vicinity of two supermassive black holes (bright spots in the image) in the galaxy. Chandra and radio data confirm that the unusual structure is due to the merger of two large galaxies, whose supermassive black holes are bound together by their mutual gravity. The swept-back appearance of the radio jets is produced by the rapid motion of the galaxy through the hot gas of the cluster, in much the same way that a motorcyclist's scarf is swept back while speeding down the road.Credit: X-Ray: NASA/CXC/D.

Is the next supercollider a good investment?

There is no doubt in my mind that society invests its billions well if it invests in theoretical physics. Whether that investment should go into particle colliders though is a different question. I don’t have a good answer to that, and I don’t see that the question is seriously being discussed. (Credit: Hossenfelder)

Craig Nelson claims that the atomic era is in its twilight years

"The atomic age is an incredible epoch, filled with people we think we know already—from Marie Curie and Albert Einstein to Ronald Reagan and the plant workers of Fukushima—but they all turn out to be a lot more complicated and interesting than any of us could’ve imagined," says Nelson.(Credit: Helvio Faria)

Einstein’s Greatest Legacy

Einstein, like no other physicist before or after him, demonstrated how the power of human thought alone, used skillfully, can allow us to consider experiments that could never be practically performed. This line of thinking, these experiments performed only in our imaginations, showed we little humans often have the power to deduce equations that govern the natural world by logical deduction alone.(Credit: Siegel, Luis Royo Fantasy Art, via Photobucket user mikenolan78)

Astronomers find the strength of the electromagnetic force hasn’t changed in ten billion years. “We didn’t see any difference between electromagnetism in these three distant galaxies and here on Earth, so we don’t support that previous finding,” says Associate Professor Michael Murphy of Swinburne University.
