NASA has released the closest-ever photos of the sun, taken by the Parker Solar Probe at just 3.8 million miles (6.1 million kilometers) from the star's surface. The new images reveal important ...

The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When ...

Physics Bizarre crystal made only of electrons revealed in astonishing detail. To capture the clearest and most direct images of a “Wigner crystal”, a structure made entirely of electrons ...

Scientists have created the world's fastest microscope, which they hope will answer fundamental questions about how electrons behave. When you purchase through links on our site, we may earn an ...

Pulses of electrons are used to represent data inside computers or to capture images in electron microscopes. The shorter the pulses, the higher the rate at which information can be transmitted.

View 2 Images 1 / 2. An artist's impression of a pulsar, thought ... Most electrons in cosmic rays have energies of a few hundred gigaelectronvolts (GeV).

This channel electron multiplier amplifies the faint signals generated in some types of mass spectrometry and other precision analytical techniques. Electrons are focused into the curved device, where ...

What did you write for the second and third pictures of covalent bonding? Center drawing: When two hydrogen atoms come close enough, their electrons are attracted to the proton of the other atom. Last ...

The changes observed in a subject between these images is what is called a microscope’s temporal resolution. ... The first light pulse, called a pump pulse, energizes a sample’s electrons.

Electrons are really, really round. A new measurement confirms the subatomic particle’s spherical shape to a record level of exactness, physicists report in the July 7 Science. That near-perfect ...

Electrons in one device gained 12.3 kiloelectron volts of energy over a distance of half a millimeter, ... for making images of thin materials with ultrahigh time resolution.

Since it has 1 more proton than electrons, sodium has a charge of +1, making it a positive ion. Chlorine gains an electron, leaving it with 17 protons and 18 electrons. Since it has 1 more electron ...
