An exoplanet smaller than Neptune with its own atmosphere has been discovered in the Neptunian Desert around its star by an international collaboration of astronomers, with the University of Warwick taking a leading role.

The rogue planet was identified in the new research, led by Dr Richard West including Professor Peter Wheatley, Dr Daniel Bayliss and Dr James McCormac from the Astronomy and Astrophysics Group at the University of Warwick.

NGTS is situated at the European Southern Observatory’s Paranal Observatory in the heart of the Atacama Desert, Chile. It is a collaboration between UK Universities Warwick, Leicester, Cambridge, and Queen’s University Belfast, together with Observatoire de Genève, DLR Berlin and Universidad de Chile.

An artificial intelligence firm says its heads-up display for astronauts could help them better manage complex space missions.

Hypergiant Industries built an “Iron Man”-inspired space helmet called HyperVSR, which can display details like an astronaut’s vital signs or other information about a mission. CEO Ben Lamm told Futurism that it may improve astronaut safety by putting more information at crew members’ fingertips and cutting down on how much they have to maneuver in a spacesuit.

“Space is an unpredictable environment, where challenges can change dramatically over the course of just a few minutes,” Lamm said. “During these situations, it’s paramount that astronaut safety is never in question. We’ve designed our helmet to enable astronauts to quickly gather information about a situation, as well as assess their own health, for enhanced decision-making even during emergencies.”

It’s easy to miss the mirror forge at the University of Arizona. While sizable, the Richard F. Caris Mirror Laboratory sits in the shadow of the university’s much larger 56,000-seat football stadium. Even its most distinctive feature—an octagonal concrete prominence emblazoned with the school’s logo—looks like an architectural feature for the arena next door. But it’s that tower that houses some of the facility’s most critical equipment.

Inside the lab, a narrow, fluorescent-green staircase spirals up five floors to the tower’s entrance. I’m a few steps from the top when lab manager Stuart Weinberger asks, for the third time, whether I have removed everything from my pockets.

“Glasses, keys, pens. Anything that could fall and damage the mirror,” he says. Weinberger has agreed to escort me to the top of the tower and onto a catwalk some 80 feet above a mirror 27.5 feet in diameter. A mirror that has already taken nearly six years—and $20 million—to make. “Most people in the lab aren’t even allowed up here,” he says. That explains Weinberger’s nervousness about the contents of my pockets (which are really, truly empty), and why he has tethered my camera to my wrist with a short line of paracord.

Scientist have just discovered that, at an atomic level, these elements have both liquid and solid states, giving context to what may be hidden in the cores of celestial bodies.

On the chain-melted phase of matter

“We develop here a classical interatomic forcefield for the element potassium using machine-learning techniques and simulate the chain-melted state with up to 20,000 atoms. We show that in the chain-melted state, guest-atom correlations are lost in three dimensions, providing the entropy necessary for its thermodynamic stability.”

Elements can be solid and liquid at same time

Humans may not be able to burp properly in space, but we can now edit a genome. For the first time, astronauts aboard the International Space Station (ISS) have used CRISPR-Cas9 to edit the DNA of brewer’s yeast.

The goal wasn’t to create super space yeast. The astronauts were studying how DNA repair mechanisms work in space, so they snipped through strands of the fungus’s genetic code in a number of places to mimic radiation damage.

“The damage actually happens on the space station and the analysis also happens in space,” said Emily Gleason of miniPCR Bio, the company that designed the DNA lab aboard the ISS. “We want to understand if DNA repair methods are different in space than on Earth.”

Using ground-penetrating radar, scientists detected a massive reservoir of frozen water sandwiched by layers of sand beneath the northern polar ice cap on Mars. This reservoir contains so much ice that, if melted and brought to the surface, it would submerge the entire planet.

“This was a surprise even for us,” Stefano Nerozzi, the lead author of the new paper and a PhD student at the University of Texas at Austin, told Gizmodo in an email.
