At CES, IBM today announced its first commercial quantum computer for use outside of the lab. The 20-qubit system combines into a single package the quantum and classical computing parts it takes to use a machine like this for research and business applications. That package, the IBM Q system, is still huge, of course, but it includes everything a company would need to get started with its quantum computing experiments, including all the machinery necessary to cool the quantum computing hardware.
Our universe could be the mirror image of an antimatter universe extending backwards in time before the Big Bang. So claim physicists in Canada, who have devised a new cosmological model positing the existence of an “antiuniverse” which, paired to our own, preserves a fundamental rule of physics called CPT symmetry.
For the precocious hunter of off-Earth life, the Drake equation is the ever-ready, go-to toolkit for estimating just how (not) lonely humans are in the Milky Way galaxy. The equation was developed by astronomer Frank Drake in 1961 in a slight hurry so that attendees of an upcoming conference would have something to confer about, and it breaks down the daunting question "Are we alone?" into more manageable, bite-size chunks.

A protoplanetary disk is the ring of dust and gas that surrounds a young star. As time passes, the material in the disk begins to coalesce into larger and larger objects, forming everything from asteroids to entire planets.
Half of the people pursuing careers as scientists at higher education institutions will drop out of the field after five years, according to a new analysis from researchers at Indiana University Bloomington.
Scientists started watching crystals sparkle in the 1990s. Those crystals sparkled more in the summer, which researchers took as evidence of dark matter. But those scientists were probably wrong, new research suggests.
Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg, Germany have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
Sitting about 6 light-years away from our sun, the red dwarf named Barnard's star is the nearest solitary star to our solar system and the fastest-moving star in our night sky. It's also really wobbly.
For a few minutes on Jan. 23, 2017, the coldest spot in the known universe was a tiny microchip hovering 150 miles over Kiruna, Sweden.
The chip was small — about the size of a postage stamp — and loaded with thousands of tightly-packed rubidium-87 atoms. Scientists launched that chip into space aboard an unpiloted, 40-foot-long (12 meters) rocket, then bombarded it with lasers until the atoms inside it cooled to minus 459.67 degrees Fahrenheit (minus 273.15 degrees Celsius) — a fraction of a fraction of a degree above absolute zero, the coldest possible temperature in nature.
When a dead star meets a giant black hole, something weird can happen. The astronomical meeting can create a zombie.
Upcoming research in the Astrophysical Journal outlines what might happen if a white dwarf encounters an intermediate-mass black hole. Its conclusion: The violent pull of the black hole could, in theory, reignite fusion inside the dead star.
If you’ve been a science fan for the last few years, you’re aware of the exciting results to emerge from the Large Hadron Collider (LHC), which in 2012 found the Higgs boson, the subatomic particle responsible for giving mass to fundamental subatomic particles.
Today, physicists have another exciting announcement to add to the Higgs saga: They have made the first unambiguous observation of Higgs bosons decaying into a matter-antimatter pair of bottom quarks. Surprisingly, the Higgs bosons decay most often in this way.
Next time you eat a blueberry (or chocolate chip) muffin consider what happened to the blueberries in the batter as it was baked. The blueberries started off all squished together, but as the muffin expanded they started to move away from each other. If you could sit on one blueberry you would see all the others moving away from you, but the same would be true for any blueberry you chose. In this sense galaxies are a lot like blueberries.
Spectacular time-lapse footage from the European Southern Observatory's Very Large Telescope (VLT) in Chile captures stars orbiting the black hole at the center of the Milky Way, including one daring star that circles incredibly close.
With every new exoplanet discovered, the same question arises: Could this world host life?
The default way scientists first approach that question is to check if the planet lies in the so-called habitable zone, the range of distances from a star in which a planet can hold liquid water on its surface. But water alone doesn't make life, so in a new paper, a team of scientists looked at another aspect of habitability: whether a planet receives enough ultraviolet radiation to create life's building blocks.
