A White Oval Cloud on Jupiter from Juno


This storm cloud on Jupiter is almost as large as the Earth. Known as a white oval, the swirling cloud is a high pressure system equivalent to an Earthly anticyclone. The cloud is one of a "string of pearls" ovals south of Jupiter's famous Great Red Spot. Possibly, the Great Red Spot is just a really large white oval that turned red. Surrounding clouds show interesting turbulence as they flow around and past the oval. The featured image was captured on February 2 as NASA's robotic spacecraft Juno made a new pass just above the cloud tops of the Jovian world. Over the next few years, Juno will continue to orbit and probe Jupiter, determine atmospheric water abundance, and attempt to determine if Jupiter has a solid surface beneath its thick clouds.

February 28th 1953: Watson and Crick discover DNA structure

On this day in 1953, scientists James D. Watson and Francis Crick discovered the chemical structure of DNA. They made the discovery of the double helix structure while building a cardboard model of the molecule in their laboratory at Cambridge University. Their model of DNA was based on an X-ray diffraction image taken by Rosalind Franklin and the fact that DNA bases are paired; due to her gender, Franklin is often forgotten in narratives of scientific history. Watson and Crick first announced their discovery to friends and it was not formally announced to the wider scientific community until April 25th. Watson, Crick and Maurice Wilkins were jointly awarded the 1962 Nobel Prize for Physiology or Medicine for their discoveries. The discovery was a groundbreaking moment for science, and lay the foundations for the research into DNA and the investigation of human genetics.

“We have found the secret of life.”
- Francis Crick

What's your favorite time period to read about and why

Great question! My academic area of expertise is nineteenth century United States, around the time of the Civil War. I find it fascinating because it was such a pivotal moment in America’s transition from revolutionary colony to global superpower. Plus, my dissertations examined fringe religious movements, and there were lots of them during the nineteenth century!

While I’ve never studied it properly I also really like Japanese history, especially the period of isolation and its dramatic end with the Meiji Restoration. It’s so interesting how they just suddenly decided to break with historic traditions and adopt of a ‘modern’ way of life.

As a Brit myself, I also like reading about twentieth century Britain. After WW2 the empire continued to fall apart and Britain faced such an identity crisis as it sought to establish its role in a postcolonial world. It certainly wasn’t always pretty, but it’s an important moment in my country’s history.

Thanks for the question!

Captain Morgan (yes, the Captain Morgan the rum is named after) was not quite a pirate. He sailed as a legally sanctioned privateer of the British Government to pillage Spanish galleons. Captain Morgan was so successful, King George II eventually knighted him!

“We speak of a manly man, but not of a whaley whale. If you wanted to dissuade a man from drinking his tenth whisky, you would slap him on the back and say, ‘Be a man.’ No one who wished to dissuade a crocodile from eating his tenth explorer would slap it on the back and say, ‘Be a crocodile.‘”

Glaciers Ebb on South Georgia Island


Frequent cloud cover in the southern Atlantic Ocean often obscures satellite images of South Georgia and the South Sandwich Islands. But occasionally the clouds give way. On September 14, 2016, the Operational Land Imager (OLI) on Landsat 8 captured natural-color images of South Georgia Island, where several glaciers are in retreat.

Crianças assustadas com ‘goblin’ na Argentina

Imagens estranhas publicadas online mostram uma misteriosa criatura rastejando em direção a alguns jovens.

O incidente peculiar teria ocorrido na cidade de Santiago del Estero, onde o grupo de crianças estavam chutando uma bola em torno de um campo de futebol num parque local.

De repente, um dos meninos (que estavam filmando o jogo) avistou algo estranho rastejando em direção a eles na grama ao longe. Ao aproximar-se para olhar mais de perto, ele gritou e todo o grupo fugiu do parque o mais rápido que podia.

Segundo relatos, a mãe de um dos meninos descreveu o encontro como “paranormal” e afirma que seu filho agora está com muito medo de voltar ao campo de futebol.

Exatamente o que estava rastejando no vídeo, no entanto, continua a permanecer um mistério.

*Goblins são criaturas geralmente verdes que se assemelham a duendes. Fazem parte do folclore nórdico, nas lendas eles vivem fazendo brincadeiras de mau gosto. Podem ser equiparadas aos trasgos e tardos do folclore português.
