Ancient magnetic fields on the Moon could be protecting precious ice | Science

For years, scientists have believed frigid craters at the Moon’s poles hold water ice, which would be both a scientific boon and a potential resource for human missions. Now, researchers have discovered a reason why the ice has persisted on an otherwise bone-dry world: Some polar craters may be protected by ancient magnetic fields. “It’s … Read more

A Huge Beam of Antimatter Has Been Caught Streaming From This Runaway Pulsar

A runaway dead star zooming through space at breakneck speeds has left behind a huge trail of matter and antimatter particles. The star is a pulsar called PSR J2030+4415 or J2030 for short; it’s around 20 kilometers (12 miles) in diameter, and it’s speeding through space at a breakneck velocity of around 450 kilometers per … Read more

Officials Confirm Several Geomagnetic Storms Are Hitting Earth This Week

The Sun is continuing its rowdy behavior, with flares and coronal mass ejections almost every day since mid-January. That means the inevitable has happened: some of those eruptions have blasted in the general direction of Earth, which means we’re in for some solar storms.   The Space Weather Prediction Center of the US National Oceanic … Read more

How Paint And a Speaker Could Explain The Physics of The Sun’s Plasma Jets

The Sun is blanketed by spiking, ultra-hot jets of plasma created from electrically charged particles, and now scientists have figured out more about how these jets (or spicules) are created and driven up into the star’s atmosphere.   Via a series of laboratory experiments and models, a new study describes the spicules as being like … Read more

‘Heartbeat’ of Black Holes Solves Decades-Old Mystery of Plasma Jets

Fluctuating light from a black hole, observed over 15 years, has revealed more about the way these enigmatic objects feed. First, a structure called a corona forms around the outside of the event horizon. Then, powerful jets of plasma launch from the poles, punching material from the corona out into interstellar space at speeds close … Read more

Giant Bubbles Expanding From The Milky Way Could Be Explained by a Single Event

Two sets of giant bubbles that extend thousands of light-years above and below the plane of the Milky Way could have been produced by the same event, in spite of their significant difference in size.   They’re called the Fermi bubbles and the eROSITA bubbles, and astronomers believe they were the result of activity by … Read more

An Expert Explains How Solar Storms Can So Easily Destroy Satellites

On Feb. 4, 2022, SpaceX launched 49 satellites as part of Elon Musk‘s Starlink internet project, most of which burned up in the atmosphere days later. The cause of this more than US$50 million failure was a geomagnetic storm caused by the Sun.   Geomagnetic storms occur when space weather hits and interacts with the … Read more

Stunning Loops of Plasma Observed on The Sun May Not Be What We Thought

A well-studied solar phenomenon may not be quite as simple as we we thought it was. New simulations suggest that what we thought were loops of plasma known as coronal loops erupting out from the surface of the Sun along magnetic field lines may, at least sometimes, be wrinkles in corrugated sheets of plasma.   … Read more

This Mind-Bogglingly Gigantic Sunspot Is Roughly The Size of Our Entire Planet

A new telescope taking on the task of staring at the Sun has delivered incredible new images of solar activity. The US National Science Foundation’s Daniel K. Inouye Solar Telescope commenced science operations for the first time on Wednesday 23 February 2022. It’s the largest solar telescope in the world, and its high-resolution observations of … Read more

Colossal Shock Wave Rippling Across Space Is Bigger Than Our Entire Galaxy

A billion years ago, an absolutely monstrous collision of two clusters of galaxies produced a pair of shock waves of absolutely epic proportions. Today, the structures gleam brightly in radio wavelengths, so huge they could easily engulf the Milky Way galaxy’s estimated 100,000 light-year diameter, stretching up to 6.5 million light-years through intergalactic space.   … Read more
