Jupiter is a strange, alien world of Mars-sized polar cyclones, colossal swirling storm systems that travel deep into the heart of the gas giant, and a gigantic magnetic field that may indicate it was generated closer to the planet’s surface than previously thought.

Algorithm Helps Drive Mars Curiosity Rover Toward Its Mount Sharp Goal

 

Analgorithmh


There are no mechanics on Mars, so the next best thing for NASA's Curiosity rover is careful driving. A new algorithm is helping the rover do just that. The software, referred to as traction control, adjusts the speed of Curiosity's wheels depending on the rocks it's climbing. After 18 months of testing at NASA's Jet Propulsion Laboratory in Pasadena, California, the software was uploaded to the rover on Mars in March. Mars Science Laboratory's mission management approved it for use on June 8, after extensive testing at JPL and multiple tests on Mars.

Origins for Life "Prepackaged" in Infant Star Systems --ALMA Observatory

"It is so exciting to discover complex organic molecules on an accretion disk around a baby star," says Chin-Fei Lee at Academia Sinica Institute of Astronomy and Astrophysics (ASIAA, Taiwan). "When such molecules were first found in the protoplanetary disk around a star in a later phase of star formation, we wondered if they could have formed earlier. Now, using ALMA's unprecedented combination of spatial resolution and sensitivity, we not only detect them on a younger accretion disk, but also determine their location. These molecules are the building blocks of life, and they are already there in the disk atmosphere around the baby star in the earliest phase of star formation."

A startling find may conceal specimens that could reveal much about evolutionary history of Jurassic era. Palaeontologists in southwest China who unearthed possibly the world’s largest fossil wall of Jurassic-era dinosaurs are hopeful that the discovery can shed new light on the creatures’ evolutionary history, Chinese media reported. The 150-meter-long fossil wall, two meters deep and eight meters high will help fill a void of research on dinosaurs’ evolutionary history.

"Physicists have been looking for extra dimensions at the Large Hadron Collider at CERN but up to now this search has yielded no results," says physicist Gustavo Lucena Gómez at Université Libre de Bruxelles. "But gravitational wave detectors might be able to provide experimental evidence."

Starting today, The Galaxy will post a new feature once a week culled from cable-news video broadcasts, radio, and print about current and future threats to planet Earth and our fragile, infant technological civilization --politics, AI and robotics, climate change, war, cosmic dangers, and an occasional dash of much needed humor.

Anonymous Hacking Collective suggested this week that NASA has already discovered traces of life in the geyser plumes  of Enceladus, but so far is keeping it secret, and is preparing to announce it in the near future.

NASA Space-Flight Discovery: Archaea Found in Extreme Earth Environments That Could Survive on Mars --"Common on Human Skin"

A new study that stemmed from a planetary protection project for NASA and the European Space Agency. It turns out our skin is crawling with single-celled microorganisms -- and they're not just bacteria. A study by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the Medical University of Graz found that the skin microbiome also contains archaea, a type of extreme-loving microbe, and that the amount of it varies with age.

"Hunting for Dinosaur's Showed Me Our Place in the Universe" (WATCH Today's 'Galaxy' Stream)

What happens when you discover a dinosaur? Paleontologist Kenneth Lacovara details his unearthing of Dreadnoughtus -- a 77-million-year-old sauropod that was as tall as a two-story house and as heavy as a jumbo jet -- and considers how amazingly improbable it is that a tiny mammal living in the cracks of the dinosaur world could evolve into a sentient being capable of understanding these magnificent creatures. Join him in a celebration of the Earth's geological history and contemplate our place in deep time.

StarTalk Radio: Earth in Human Hands --"Dealing with Ourselves as a Planetary Force"

 
Maxresdefault

 

Curious about what’s happened to Earth in the Anthropocene age – and what’s going to happen in the future? It’s not all doom and gloom, as you’ll find out from our host, astrobiologist David Grinspoon, author of the new book, Earth in Human Hands – Shaping Our Planet’s Future. In this episode, rather than the demonization of climate change deniers you might expect, what you will hear is a thoughtful discussion about the Anthropocene age, i.e., the age of humanity on Earth, and how we are dealing with ourselves as a planetary force.
