Astronomers Capture the Sharpest Image yet of a Monster Galaxy 12.4 Billion Light Years Away
Posted by Shubham Ghosh Roy in category: space
A team of scientists obtained a magnificent photograph of a faraway galaxy, reminding us all how little we are in the grand scheme of things.
This monster galaxy’ is around 12 billion light-years away from Earth and produces new stars 1,000 times faster than our own Milky Way galaxy.
Scientists utilized the £1.1 billion ALMA Observatory in Chile to capture views of the galaxy with a resolution ten times better than any previous attempt, naming it ‘COSMOS-AzTEC-1.’

What Happens When Black Holes Die?
Posted by Shubham Ghosh Roy in categories: cosmology, quantum physics
Stephen Hawking’s suggestion that black holes “leak” radiation left physicists with a problem they have been attempting to solve for 51 years.
In what is arguably his most significant contribution to science, Stephen Hawking suggested that black holes can leak a form of radiation that causes them to gradually ebb away, and eventually end their lives in a massive explosive event.
This radiation 0, later called “Hawking radiation,” inadvertently causes a problem at the intersection of general relativity and quantum physics — the former being the best description we have of gravity and the universe on cosmically massive scales, while the latter is the most robust model of the physics that governs the very small.

Unexpected Solar Wind Stream Hits Earth at 372 Miles Per Second
Posted by Shubham Ghosh Roy in category: futurism
On Sunday, Earth’s magnetic field was pelted by a solar wind stream reaching velocities of more than 600 kilometers (372 miles) per second.
While that’s nothing too alarming – solar storms often pummel our planet triggering spectacular auroras – what is weird is that this storm was totally unexpected.
“This event was not in the forecast, so the resulting auroras came as a surprise,” SpaceWeather reported.

Nuclear power’s biggest problem could have a small solution
Posted by Shubham Ghosh Roy in categories: nuclear energy, particle physics
For decades, if you asked a fusion scientist to picture a fusion reactor, they’d probably tell you about a tokamak. It’s a chamber about the size of a large room, shaped like a hollow doughnut. Physicists fill its insides with a not-so-tasty jam of superheated plasma. Then they surround it with magnets in the hopes of crushing atoms together to create energy, just as the sun does.
But experts think you can make tokamaks in other shapes. Some believe that making tokamaks smaller and leaner could make them better at handling plasma. If the fusion scientists proposing it are right, then it could be a long-awaited upgrade for nuclear energy. Thanks to recent research and a newly proposed reactor project, the field is seriously thinking about generating electricity with a “spherical tokamak.”
“The indication from experiments up to now is that [spherical tokamaks] may, pound for pound, confine plasmas better and therefore make better fusion reactors,” says Steven Cowley, director of Princeton Plasma Physics Laboratory.
