We only get to see roughly 0.5% of the earth from where we live on the surface. One of the greatest mysteries of our planet is the solid iron core, which is located deep below the crust, heated rock mantle, and liquified outer core. According to a new study, the iron ball that makes up

Scientists Simulated a Black Hole in The Lab, And Then It Started to Glow

A new kind of black hole analog could tell us a thing or two about an elusive radiation theoretically emitted by the real thing. Using a chain of atoms in single-file to simulate the event horizon of a black hole, a team of physicists has observed the equivalent of what we call Hawking radiation –

JWST Has Found Life’s Elemental Building Blocks in The Depths of Darkest Space

JWST’s unparalleled ability to peer into the shrouded hearts of distant clouds has revealed the elements of biochemistry in the coldest and darkest place we’ve seen them yet. In a molecular cloud called Chamaeleon I, located over 500 light-years from Earth, data from the telescope has revealed the presence of frozen carbon, hydrogen, oxygen, nitrogen,

The Latest Milky Way Survey Shows Off an Incredible 3.32 Billion Celestial Objects

If you check in regularly to ScienceAlert, you’ll be familiar with quite a few stunning space images, but a newly published picture has to be one of the best yet: 2 years in the making, 10 terabytes worth of data, 21,400 individual exposures combined, and a final image showing a huge 3.32 billion celestial objects.

This Physicist Says Electrons Spin in Quantum Physics After All. Here’s Why

‘Spin’ is a fundamental quality of fundamental particles like the electron, invoking images of a tiny sphere revolving rapidly on its axis like a planet in a shrunken solar system. Only it isn’t. It can’t. For one thing, electrons aren’t spheres of matter but points described by the mathematics of probability. But California Institute of

James Webb Space Telescope Discovers Water Ice at Ringed Asteroid Chariklo ‘By Remarkable Luck’

The most comprehensive plans need a sprinkle of luck, even in space. In October 2022, the James Webb Space Telescope (JWST or Webb) watched as Chariklo, a tiny ringed asteroid, eclipsed a star. This event, called an occultation, marked a first for Webb. At the month’s end, Webb turned toward Chariklo again and notched another

It’s Official: NASA Confirms We’ve Found 5,000 Worlds Outside The Solar System

The count of confirmed exoplanets just ticked past the 5,000 mark, representing a 30-year journey of discovery led by NASA space telescopes. Not so long ago, we lived in a universe with only a small number of known planets, all of them orbiting our Sun. But a new raft of discoveries marks a scientific high

The JWST’s Data Is So Incredible That Even Those Who Built It Are Questioning Previous Science

UC Santa Cruz astronomer Garth Illingworth, former Deputy Director of the Space Telescope Science Institute, has had a hell of a career. He’s dedicated decades to the pursuit of finding and understanding the most distant galaxies, and was a leader on the team that built the Hubble Space Telescope. And before the Hubble was even

Device transmits radio waves with almost no power—without violating the laws of physics

A new ultra-low-power method of communication at first glance seems to violate the laws of physics. It is possible to wirelessly transmit information simply by opening and closing a switch that connects a resistor to an antenna. No need to send power to the antenna. Our system, combined with techniques for harvesting energy from the

Scientists Actually Did It: They Built a Real Working Tractor Beam

Tractor beams have long been a staple of sci-fi, but you might not know that they’ve also existed in the real world for some time, albeit at a very small scale. Microscopic tractor beams, better known as optical tweezers, can pull atoms and nanoparticles for use in medicine and research. But we’ve never actually been

James Webb Telescope’s Ghostly ‘Pillars of Creation’

Why satisfy yourself with one course when you can have a double helping? The US space agency Nasa has issued a second image of the famous “Pillars of Creation” taken by the new super space telescope, James Webb. This week we get a rendering of the active star-forming region as seen by Webb’s Mid-Infrared Instrument

Scientists Turn Nuclear Waste Into Diamond Batteries That Could Last For Thousands Of Years

We have an unquenchable energy need. When we need to run anything that cannot be plugged in, electricity will have to come from a battery, and the quest for a better battery is being launched in laboratories around the globe. Hold that thought for a moment. Nuclear waste is radioactive waste generated by nuclear power

Quantum magnet is billions of times colder than interstellar space

A new kind of quantum magnet is made up of atoms only a billionth of a degree warmer than absolute zero – and physicists aren’t certain how it behaves. A regular magnet strongly repels or attracts magnetic objects depending on whether electrons inside it are in an “up” or a “down” quantum spin state, a
