Storm Chasing on Saturn with Cassini
.] - "The sun is slowly rising over Saturn's north pole, exposing an immense six-sided hurricane. The storm, big enough to swallow four Earths, was first spotted by the Voyager missions in the early 1980s. [Cassini
] will be passing directly over the north pole with its cameras pointing down later this month." (previously 1

Art forgeries have long been the stuff of thrillers, with fake da Vincis or Vermeers fooling connoisseurs, roiling the art world, and moving millions of dollars.
We don’t think of ancient books driving such grand forgery, intrigue, and schadenfreude. This is changing thanks in part to a clever forgery of Galileo’s landmark book Sidereus Nuncius, published in Venice in 1610. Arguably one of the most extraordinary scientific publications of all times, Sidereus Nuncius turned Galileo into the brightest new star of Western science. Four centuries later, a faked copy of this book has disarmed a generation of Galileo experts, and raised a host of intriguing questions about the social nature of scholarly authentication, the precariousness of truth, and the revelatory power of fakes.

"My subject is a barren one – the world of nature, or in other words life; and that subject in its least elevated department, and employing either rustic terms or foreign, nay barbarian words that actually have to be introduced with an apology. Moreover, the path is not a beaten highway of authorship, nor one in which the mind is eager to range: there is not one of us who has made the same venture, nor yet one Roman who has tackled single-handed all departments of the subject."Naturalis Historia
was written by Pliny the Elder
between 77 and 79 CE and was meant to serve as a kind of proto-encyclopedia discussing all of the ancient knowledge available to him, covered in enough depth and breadth to make it by a reasonable margin the largest work to survive to the modern day from the Roman era. The work includes discussions on astronomy, meteorology, geography, mineralogy, zoology and botany organized along Aristotelian divisions of nature but also includes essays on human inventions and institutions. It is dedicated to the Emperor Titus in its epistle to the Emperor Vespasian
, a close friend of Pliny who relied on his extensive knowledge, and its unusually careful citations of sources as well as its index makes it a precursor to modern scholarly works. It was Pliny's last work, as well as sadly his sole surviving one, and was published not long before his death attempting to save a friend from the eruption of Mt. Vesuvius that destroyed Pompeii and Herculaneum
, famously recounted by Pliny's eponymous nephew Pliny the Younger

O’Bryan walked me slowly down the steep side of the mesa, to the desert floor, so I could see Star Axis in its entirety. The work’s centrepiece is a 10-storey staircase that lets you walk up through the rock of the mesa, your eyes fixed on a small circular opening that cuts through the top of the pyramid. The first section of the staircase is roofless and open to the sky, but the end of it has a stone overhang that makes it look and feel like a tunnel. This ‘star tunnel’, as Ross calls it, is precisely aligned with Earth’s axis. If you bored a tunnel straight through the Earth’s core, from the South Pole to North Pole, and climbed up it, you’d see the same circle of sky that you do when you walk through Ross’ tunnel. Gazing up through it in the afternoon glare, I saw a patch of blue, the size and shape of a dime held at arm’s length. But if the sun had blinked for a moment, fading the heavens to black, I’d have seen Polaris, glittering at the end of the tunnel, like a solitary diamond in the void.

An intriguing essay
on how young women in Georgian England were able to do science by hiding in the pursuits of the domestic arts.
"Women didn’t find it easy to participate in late eighteenth century science. Experimentation and discovery were not easily compatible with the ideals of domestic femininity – but there were women who rejected these social expectations and became active and renowned."

In the telling it has the contours of a creation myth: At a time of great evil and great terror, a small group of scientists, among the world’s greatest minds, secluded themselves in the desert. In secrecy and silence they toiled at their Promethean task. They sought the ultimate weapon, one of such great power as to end not just their war, but all war. They hoped their work would salvage the future. They feared it could end everything.

A planet with about the same mass as Earth
has been discovered in orbit around Alpha Centauri B, a star in the Alpha Centauri triple star system - the solar system's closest neighbor, a mere 4.3 light years away. Alpha Centauri B is very similar to the Sun, and this marks the first planet with a mass similar to Earth ever found around a Sun-like star. However, the planet is orbiting at a distance of about six million kilometers, much closer than Mercury is to the Sun in the Solar System, so temperatures above 400 degrees Celsius may make vacationing there unpalatable even for the most dedicated beach-goer. However, lead paper author Xavier Dumusque called it "a major step towards the detection of a twin Earth in the immediate vicinity of the Sun."

Where's Tyche, the 10th 9th planet? Getting the full story.
John Matese and Daniel Whitmire of the University of Louisiana at Lafayette recently made the news when they announced the possible discovery of a gas giant planet they named Tyche
in the Oort Cloud, at the extreme edge of the Solar System (previously
). Now ars electronica breaks down the evidence behind the announcement, what can be done to confirm or disprove its existence & how long it could take.
