Scientists Spotted Evidence of an Unseen Universe—Even Though That Should Be Impossible
But there is one ancient light we can see that we shouldn’t be seeing at all.As part of the James Webb Space Telescope Advanced Deep Extragalactic Survey (JADES), NASA’s James Webb Space Telescope ...
Milky Way’s cold gas clouds mapped in unprecedented detail by MeerKAT Absorption Line Survey
Such hydrogen atoms may eventually transform into molecular gas, the basic fuel for star formation. Therefore, these cold gas ...

Lesson 4.1: Protons, Neutrons, and Electrons
The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

Lesson 4.4: Energy Levels, Electrons, and Covalent Bonding
When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...
Webb telescope spots galaxy at pivotal moment in the early universe
Scientists using the James Webb Space Telescope have identified an ancient and faraway galaxy that provides evidence that an ...

Probe The Galaxy On A Shoestring With This DIY Hydrogen-Line Telescope
As the wonderfully named [ArtichokeHeartAttack] explains in the remarkably thorough project documentation, the characteristic 1420.4-MHz signal emitted when the spins of a hydrogen atom’s proton ...

Collaborative analysis improves theoretical understanding of hyperfine splitting in hydrogen
An atom of hydrogen is made up of an electron orbiting a proton. The overall energy level of hydrogen depends on the spin orientation of the proton and electron. If one is up and one is down ...
