Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
How cold? Lower than 0.05 Kelvin (-272°C).
NASA's Hubble Space Telescope is observing such stars through a large program called HAZMAT — Habitable Zones and M dwarf Activity across Time.
An unprecedented, close examination of the electron has opened a window into the mind-bending nature of particles, energy and forces at infinitesimal scales.
Mercury is the smallest planet of our solar system, and it is closest to the sun at a distance of only about 58 million kilometers. As a result, the…
We live in an age of long-range information, transmitted either by underground optical fibre or by radio frequency from satellites. But the throughput today is…
On October 16, 2017, an international group of astronomers and physicists excitedly reported the first simultaneous detection of light and gravitational waves…
In this form, the phosphorus atoms arrange in a honeycomb structure similar to graphene, however, not completely flat but regularly “buckled”.
With modern optical imaging techniques, the position of objects can be measured with a precision that reaches a few nanometers. These techniques are used in…
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold…
There will be near-future situations, in which highly automated and autonomous vehicles will also utilize a remote human operator. For example, a truck that…
