Imagem de supertelescópio registra sinais inéditos de nascimento de planeta

Astrônomos acreditam ter encontrado um novo planeta bebê “nascendo”.

Seria a primeira vez que imagens desse tipo são capturadas.

Os cientistas estavam observando uma jovem estrela chamada AB Aurigae, que fica a 520 anos-luz da Terra, quando notaram um denso disco de poeira e gás girando em torno dela.

No fundo desse disco de poeira e gás, eles encontraram uma estrutura em espiral com uma “torção” perto do centro, um sinal de um novo planeta sendo formado.

As imagens foram capturadas com o VLT (sigla em inglês para Telescópio Muito Grande) do Observatório Europeu do Sul. Localizado no deserto do Atacama, no Chile, o megatelescópio, o maior do mundo, é usado por astrônomos para estudar o universo.

“Milhares de exoplanetas foram identificados até agora, mas pouco se sabe sobre como eles se formam. Precisamos observar sistemas muito jovens para realmente capturar o momento de quando planetas se formam”, disse Anthony Boccaletti, que liderou o estudo no Observatório de Paris, na França.

No passado, era muito difícil capturar imagens nítidas e profundas o suficiente desses discos, de forma a encontrar a marcação de “torção” que evidencia o nascimento de um planeta.

O Observatório Europeu do Sul está atualmente construindo um novo telescópio, o ELT (sigla em inglês para Extremely Large Telescope), também no Chile. Os cientistas esperam que o ELT permita que os planetas sejam estudados com ainda mais detalhes.

Duke Kahanamoku reflects on surfing, Olympics, and old Hawaii in 1966 interview

Duke Kahanamoku is the most influential surfer of all time and is often hailed as the father of modern surfing. There is nearly no one questioning these titles. Recently, Public Broadcasting Service (PBS) Hawaii unveiled a never-before-seen interview with the legendary surfer and Olympic swimmer. In the 1966 episode of Pau Hana Years, a seminal Hawaii television program that aired on KHET-TV (now PBS Hawaii) for 16 years, running from 1966 until 1982, Bob Barker chats with Duke Kahanamoku, then 76. The conversation drifts from royal ancestry to Olympic lanes, from Hollywood sets to a surfboard shaped by hand, tracing the outline of a life that helped define modern surfing and Hawaii's public image in the 20th century. And if you know little about the man who dreamed of getting surfing into the Olympic Games, this is a precious piece of history. A name with history, worn casually The interview starts with Kahanamoku explaining that "Duke" is not a title but his giv...

The hydrodynamics of surfboard fins

Have you ever wondered why a surfboard fin looks like that? It is a single or a set of fixed blades or keels located under a board, near the tail, often no bigger than a hand. Yet that small surface is where much of the surfboard's behavior takes place. Speed, hold, looseness, and the feeling of control all trace back to how water moves around fins. The physics of surfboard fins falls under hydrodynamics, the study of how fluids behave in motion. So, according to science, they feature a shape designed to turn flowing water into several forces. Let's take a look at what's at stake when fins and water interact. Lift and the feeling of control One of the key variables in hydrodynamic terms involving surfboard fins is lift. When a surfer leans into a turn, the board tilts and the fins meet the water at an angle. The angle is enough to create a pressure difference between the two sides of the fin. Water speeds up on one side and slows on the other. The result is a sidewa...

How paddleboarding transforms your body and mind

Adventure is on our doorstep. With so many different bodies of water available to paddleboarders, from city canals to coastal routes, we can find adventure in places much closer to home than people might initially expect. According to the Canal and River Trust, 50 percent of people in England and Wales live within just eight kilometers of a canal or river, and eight million people live less than one kilometer away. I had lived within just a few kilometers of the Leeds and Liverpool Canal for years and never really explored it before stand-up paddleboarding (SUP) came into my life . The challenge created both a new perspective and a deeper love for where I lived and the areas which I passed through. On my coast-to-coast journey, I slept in my own bed for two nights as the route passed through my then hometown of Skipton, yet I felt I was on a grand journey of discovery. We are braver, stronger, and more resilient than we think. SUP not only helps us feel more connected to our va...
