The "Science and Space" Thread #2
Big Bang Conditions Created in Lab.
By smashing gold particles together at super-fast speeds, physicists have basically melted protons, creating a kind of "quark soup" of matter that is about 250,000 times hotter than the center of the sun and similar to conditions just after the birth of the universe.

Meet the new space brick, now with added potato and a pinch of salt
There’s a different kind of space race under way, one that has engineers trying to crack the code on the best way to build on other celestial bodies. Concepts to build on the Moon have included using lunar dust and materials that could generate electricity, while for Mars scientists have explored no-bake bricks and 3D-printed ones using planetary minerals.
Now, from the team that earlier developed AstroCrete, fashioned out of blood, urine and Martian dirt, comes the slightly more palatable StarCrete, made from extraterrestrial dust, potato starch and a dash of salt. And the team says it’s strong enough that it could feasibly build houses on the planet.
UK backs Rolls-Royce project to build a nuclear reactor on the moon
The UK Space Agency said Friday it would back research by Rolls-Royce
looking at the use of nuclear power on the moon.
In a statement, the government agency said researchers from Rolls-Royce had been working on a Micro-Reactor program “to develop technology that will provide power needed for humans to live and work on the Moon.”
College students built a satellite with AA batteries and a $20 microprocessor
It costs a lot of money to get a satellite into orbit onboard a rocket—around $50 million minimum, to be more specific. While this massively restricts who can access the space industry, it’s not all bad. According to NASA, there are approximately 27,000 hunks of space junk orbiting high above humans’ heads at the moment, with an average of 25 years before they fall from orbit and burn away upon atmospheric reentry.
Still, lowering costs while also shortening satellite lifespans is important if space exploration and utilization is to remain safe and viable. As luck would have it, a group of students and researchers at Brown University just made promising headway for both issues.

A research team has developed one of the world's fastest single-shot laser cameras, which is at least a thousand times faster than today's most modern equipment for combustion diagnostics. The discovery has enormous significance for studying the lightning-fast combustion of hydrocarbons.
Astronomers discover first direct evidence of vulcanism on Venus
After decades of speculation, astronomers have discovered the first direct evidence of volcanic activity on Venus. Radar images of Earth’s “twin” taken just a few months apart reveal a recent eruption.
Northrop Grumman and IHI partner to develop patrol satellites
Space may be the final frontier, but it still needs someone to keep the peace. To help achieve this, Northrop Grumman and Tokyo-based IHI Corporation are teaming up to develop small, highly maneuverable Space Domain Awareness (SDA) satellites for Japan to protect commercial satellites from potentially hostile spacecraft.
Huge solar tornado as tall as 14 Earths hurls plasma cloud into space.
NASA's Solar Dynamics Observatory captured what might be 'the tallest tornado' in the solar system swirling across the north pole of the sun.
Private Japanese spacecraft enters lunar orbit ahead of landing attempt
Japan may soon join a very exclusive club as its privately-led Hakuto-R Mission 1 lunar lander went into orbit around the Moon on March 21 at 10:24 JST after completing a controlled main engine burn in anticipation of a landing attempt in late April.
Giant galaxy redefined after flipping jet to point straight at Earth
At the heart of most galaxies lies a supermassive black hole, and in some cases these monsters are busily chowing down on material and emitting higher levels of radiation. A region undergoing this process is called an active galactic nucleus (AGN) or a quasar. Some of them are such messy eaters that they’re spewing off huge jets of charged particles traveling close to the speed of light. These jets can point away from the home galaxy in any direction, and if one just so happens to be pointing towards Earth, it appears as a very bright object called a blazar.
Glass beads on moon’s surface may hold billions of tonnes of water, scientists say
Tiny glass beads strewn across the moon’s surface contain potentially billions of tonnes of water that could be extracted and used by astronauts on future lunar missions, researchers say.
The strongest evidence for a Universe before the Big Bang
-
For many decades, people conflated the hot Big Bang, describing the early Universe, with a singularity: that this "Big Bang" was the birth of space and time.
[*]However, in the early 1980s, a new theory called cosmic inflation came along, suggesting that before the hot Big Bang, the Universe behaved very differently, pushing any hypothetical singularity unobservably far back.
[*]Earlier this century, some very strong evidence arrived showing that there was a Universe before the Big Bang, demonstrating that the Big Bang wasn't truly the start of it all.
Interesting. Thanks Mike!
James Webb sheds more light on exoplanets’ ability to support life
![Atmosphere Moon Natural environment Sky Astronomical object]()
Researchers have used the James Webb Space Telescope to measure the temperature of the innermost planet in the TRAPPIST-1 system, shedding more light on the ability of planets like these to support life.
TRAPPIST-1 is an ultracool red dwarf star (or M dwarf) barely larger than Jupiter that sits about 40 light-years away and is orbited by seven Earth-sized exoplanets. It’s up to twice as old as our own solar system, making it perfect for studying the formation and evolution of terrestrial planets.
Ultramassive black hole found, 33 billion times the mass of the Sun
A team of astronomers in the UK has made a massive discovery, using gravitational lensing to locate one of the biggest black holes to date.
At 32.7 billion solar masses, this ultramassive black hole is positioned in center of the gigantic elliptical galaxy Abell 1201 BCG, in the galaxy cluster Abell 1201, some 2.7 billion light-years away from Earth.
40 years of Saturn data uncovers never-before-seen ring phenomenon
Saturn is renowned for its rings, easily visible through an ordinary telescope. Now, using observations collected over 40 years, scientists have discovered that the planet’s iconic rings may not be as calm as they look, uncovering a never-before-seen interaction between the planet and its iconic rings.
Space scientists reveal brightest gamma explosion ever
The blast was officially named GRB 221009A but has been nicknamed the BOAT - Brightest Of All Time - by those working on a mission Nasa calls Swift.
SpaceX prepares for rehearsal, test flight of Starship rocket
SpaceX plans to carry out a launch rehearsal next week of Starship, the most powerful rocket ever built, and its first test flight possibly the following week, the private space company said Thursday.
