Astronomers were able to use powerful telescopes to zoom 1,350 light-years away from Earth into the Orion Nebula. Here’s what they found.

Our galaxy may contain billions of habitable worlds that don’t host any life. Should we attempt to change that?Claudius Gros at the Goethe University Frankfurt, Germany, thinks we should. He believes in directed panspermia: deliberately seeding life throughout the cosmos. And to do that, he proposes we use a laser propulsion system that may not be technically out of reach.

Breakthrough Starshot is a project with ambitious aims to use such systems to send tiny, lightweight probes to Alpha Centauri. The goal is to take pictures of our nearest star, but these systems could also deliver much larger payloads into orbit around nearby stars, says Gros.

You’re looking at an image of an enormous ring of debris, 237 light years away from Earth, orbiting a long-studied, young star called HR 4796A. While the bright white ring of debris may be the most visually striking part of the image, astronomers are more excited about what’s around it: the much larger, less-concentrated area of dust around it.

Scientists have long known about the dust and ring surrounding the star. The ring alone is 77 astronomical units in radius, almost twice Pluto’s average distance from our our sun. But a team recently took another look with the Hubble Space Telescope, and learned that the structure was in fact much larger and more complex than they previously thought.

“The resulting images unambiguously reveal the debris ring embedded within a much larger, morphologically complex, and biaxially asymmetric exo-ring scattering structure,” the authors wrote in the paper published recently in The Astronomical Journal. In other words, it’s big and weird-shaped. Check it out:

An Australian research team are considering the benefits of “trying to land” an asteroid on earth for mining possibilities.

In the course of the last century, science fiction has been a harbinger of things to come. From the automatic sliding doors of Star Trek to visual communication, cyberspace, and even the moon landing, many of our present technological achievements were dreamed up in the futuristic visions of science fiction authors of the 1960s and 70s. Indeed, the fantastical world of science fiction, while not intended to be prophetic, has ended up acting as a blueprint for our modern world.

We have learned from science fiction not only the possibilities of technology, however, but also its irreconcilable dangers. Readers of the genre will recognize the many stories warning us of the hazards of space travel, mind enhancement, and artificial intelligence. These fictional accounts cautioned that if we were not careful, our freedom to transform the world around us would transmogrify into a self-enforced slavery.

Nonetheless, while many of us remembered that these were just stories, intended as speculations about a possible future—in other words, they were fiction before science—through them, we became used to the idea that any advanced technology was inherently dangerous and its use always suspect. Moreover, it became a commonplace idea that technologies whose aim was to change or transform the human being—whether genetic, biological or reconstructive—would lead to a future worthy of Mary Shelley’s Frankenstein.

China is intensifying its push into space, and broadening its astronaut recruiting.

The Chinese government, which plans to increase the number of manned missions in its military-backed space program to around two a year, will soon begin recruiting civilian astronauts, Yang Liwei, deputy director of the China Manned Space Engineering Office, told reporters on the sidelines of a ceremonial parliament session this weekend. That’s a departure from China’s practice of drawing its astronauts from among air force pilots.

Yang—who was China’s first man in space in 2003—said the trainees could include private-sector maintenance engineers, payload specialists, pilots, scientists, and people from universities and other research institutions, according to the Associated Press. More women are also being encouraged to apply. The loosening of restrictions comes amid NASA’s announcement that it has recruited America’s most competitive class of astronauts ever, as well as other initiatives like Canada’s Hunger Games -style search for new astronauts on the internet.

“To have the opportunity to talk to someone like that and to show what we did, it feels great,” said participant Ruby Novoa Forcier, 18.

Saint-Jacques’ visit was part of the Robotics FIRST (Favoriser l’Inspiration et la Reconnaissance des Sciences et de la Technologie) Quebec competition.

Around 5,000 students from different schools across Quebec, the United States and Europe got the chance to compete at the event.
