The galactic bulge at the heart of the Milky Way is haunted by the ghosts of dead stars spread out as a mysterious arrangement of planetary nebulas.
Flying cars. Space tourism. Safe reentry for astronauts coming back from Mars.
These technologies are still science fiction, but some won’t be for much longer, according to Charles “Mike” Fremaux, NASA Langley Research Center’s chief engineer for intelligent flight systems.
To test these concepts, particularly in regard to public and military safety, NASA Langley is building its first new wind tunnel in over 40 years. The NASA Flight Dynamic Research Facility, a project Fremaux has been pursuing for 25 years, will replace two smaller wind tunnels that are around 80 years old. The center’s most recent and largest, the National Transonic Facility, was built in 1980.
This could help us improve our understanding of the Sun and its impact on space weather.
A collaborative effort between researchers at the University of Graz in Austria and the Skolkovo Institute of Science and Technology (Skoltech) in Russia used artificial intelligence (AI) to study the magnetic field in the upper atmosphere of the Sun, a press release said.
The solar magnetic field is a poorly understood area of research among astronomers. Even after centuries of watching the Sun, we only have limited information about how sunspots are formed or whether they will lead to events like a flare or a coronal mass ejection (CME).
2020 underwater base.
Aquanaut Fabien Cousteau — grandson of famed ocean explorer Jacques-Yves Cousteau — has announced plans to build the world’s biggest underwater base for scientific research.
He calls the facility “Proteus” and envisions it being the ocean equivalent of the International Space Station — a place where scientists from across the globe can work together to solve the world’s biggest problems, from climate change to world hunger.

NASA has shared an image of three spacecraft that will play a central role in its next three Artemis missions to the moon.
Having already successfully tested the Orion spacecraft on a lunar flyby at the end of last year after being blasted to space by NASA’s new Space Launch System rocket, the American space agency is now overseeing the building of three more Orion capsules for upcoming Artemis missions.
😗 year 2017.
Searing temperatures, radiation and lack of air didn’t kill algae kept outside the International Space Station – so maybe life from space could colonise worlds.
Venus is one of the most brutally inhospitable places in our solar system, but many scientists think life may have thrived there at one point. Here’s why.
For many, the word “crystals” conjures images of shimmering suncatchers that create a prism of rainbow colors or semi-transparent stones thought to possess healing abilities. But in the realm of science and engineering, crystals take on a more technical definition. They’re perceived as materials whose components – be it atoms, molecules, or nanoparticles –are arranged regularly in space. In other words, crystals are defined by the regular arrangement of their constituents. Familiar examples include diamonds, table salt, and sugar cubes.
Astronomers at the University of Sydney have shown that a small, faint star is the coldest on record to produce emission at radio wavelength.
The ‘ultracool brown dwarf’ examined in the study is a ball of gas simmering at about 425 degrees centigrade—cooler than a typical campfire—without burning nuclear fuel.
By contrast, the surface temperature of the sun, a nuclear inferno, is about 5,600 degrees.
India has launched its third Moon mission and is hoping to become to the first to land near its south pole – which has rarely been explored.
If successful, the Chandrayaan-3’s orbiter, lander and a rover are due to touch down on the Moon’s surface on 23 or 24 August.
