ATLAS detector at CERNThis massive detector at CERN is searching for the smallest things in the universe. There is a man standing on the yellow platform to give a sense of scale.https://feeds.sherborne.org/images/physics/phenomena/img/ATLAS%20detector%20at%20CERN.jpgSaggitarius A*This is the first image of Sgr A*, the supermassive black hole at the centre of our galaxy. It’s the first direct visual evidence of the presence of this black hole. It was captured by the Event Horizon Telescope (EHT), an array which linked together eight existing radio observatories across the planet to form a single “Earth-sized” virtual telescope.https://feeds.sherborne.org/images/physics/phenomena/img/Black%20hole.jpg© 2022 EHT CollaborationBouncing BallThis classic photograph by Berenice Abbott shows a time lapse of a ball bouncing, clearly showing the parabolic paths taken in each bounce. The gradual reduction in the height of the bounce shows that each bounce is inelastic - energy is being lost. Where does it go?https://feeds.sherborne.org/images/physics/phenomena/img/Bouncing%20ball.jpg© 2022 Estate of Berenice AbbottBubble ChamberA bubble chamber is a vessel filled with a superheated transparent liquid (most often liquid hydrogen) used to detect electrically charged particles moving through it. It was invented in 1952 by Donald A. Glaser, for which he was awarded the 1960 Nobel Prize in Physics. Supposedly, Glaser was inspired by the bubbles in a glass of beer; however, in a 2006 talk, he refuted this story, although saying that while beer was not the inspiration for the bubble chamber, he did experiments using beer to fill early prototypes.https://feeds.sherborne.org/images/physics/phenomena/img/Bubble%20Chamber.jpgTrees can glow during thunderstormsThe purple light emanating from these spruce needles is emitted by weak electric discharges. Physicists placed this branch of a spruce tree below a charged aluminum plate and grounded it with a metal wire. The electric field formed by the two metals’ attraction has a strength that is about 1/75 of that of fields required for lightning. In response to the field, an electric charge travels up the branch to the tips of the leaves, where it is released into the air.https://feeds.sherborne.org/images/physics/phenomena/img/Lightning%20and%20Tree.jpgMicroprocessorUsing beams of electrons it is possible to image the individual transistors on a microprocessor. There are millions of transistors on a typical chip, so how small are the details in this image?https://feeds.sherborne.org/images/physics/phenomena/img/Microprocessor.jpgNewton's CradleNewton's cradle is a device that demonstrates the conservation of momentum and the conservation of energy with swinging spheres. When one sphere at the end is lifted and released, it strikes the stationary spheres, transmitting a force through the stationary spheres that pushes the last sphere upward. The last sphere swings back and strikes the nearly stationary spheres, repeating the effect in the opposite direction. The device is named after 17th-century English scientist Sir Isaac Newton and designed by French scientist Edme Mariotte.https://feeds.sherborne.org/images/physics/phenomena/img/Newtons%20Cradle.jpgSolar FlaresA solar flare is an intense localised eruption of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other solar phenomena.https://feeds.sherborne.org/images/physics/phenomena/img/Solar%20Flares.jpgSparksElectrical sparks form when the electric field is strong enough to rip electrons off the atoms in a gas. Visible light is emitted as the electrons lose energy again. Lightning is produced in just the same way, though on a rather larger scale, with voltages in the region of 100000 V!https://feeds.sherborne.org/images/physics/phenomena/img/Sparks.jpgSuper-KamiokandeSuper-Kamioka Neutrino Observatory is a neutrino observatory located under Mount Ikeno near the city of Hida, Gifu Prefecture, Japan. It is located 1,000 m underground in the Mozumi Mine in Hida's Kamioka area. The observatory was designed to detect high-energy neutrinos, to search for proton decay, study solar and atmospheric neutrinos, and keep watch for supernovae in the Milky Way Galaxy. In this image you can see engineers carrying out maintenance in an inflatable dinghy!https://feeds.sherborne.org/images/physics/phenomena/img/Super-Kamiokande.jpgWesterlund 2The star cluster Westerlund 2 in the Milky Way galaxy, with an estimated age of about one or two million years. It contains some of the hottest, brightest, and most massive stars known. The cluster resides inside a stellar breeding ground known as Gum 29, located 20,000 light-years away in the constellation Carina.This was the Official Hubble 25th Anniversary Image in 2015.https://feeds.sherborne.org/images/physics/phenomena/img/Westerlund%202.jpg
