Major solar flare disrupts Hurricane Ian disaster response

Emergency responders dealing with the tragic aftermath of Hurricane Ian in Florida and the Carolinas may have suffered extra setbacks on Sunday (Oct. 2) as a major solar flare disrupted radio communications.  The solar flare, a powerful X1 (the mildest form of the strongest category of flares) erupted from the sun on Sunday at 3:53…

Newborn volcanic island spotted from space (satellite photo)

On Dec. 21, 2021, the Hunga Tonga-Hunga Ha’apai undersea volcano in Tonga erupted with explosive force, sending a shockwave that went around the world several times. There’s currently another eruption happening in the Pacific nation, which comprises around 170 islands, but it’s a much calmer situation. The underwater Home Reef seamount has risen above the…

Can stringy physics rescue the universe from a catastrophic transformation?

Our universe may be fundamentally unstable. In a flash, the vacuum of space-time may find a new ground state, triggering a cataclysmic transformation of the physics of the universe. Or not. A new understanding inspired by string theory shows that our universe may be more stable than we previously thought. A broken universe  Within the…

Near-Earth asteroid Ryugu was born in the outer solar system 4 billion years ago

An analysis of samples collected from the asteroid Ryugu has revealed its origins and birthplace. The findings show that even though Ryugu is now classified as a near-Earth object, its journey to the inner solar system began hundreds of millions of miles away and billions of years ago. Asteroids like Ryugu are composed of unspoiled…

Scientists need your help to confirm Jupiter-like exoplanets

If you’ve ever dreamed of discovering a new planet, now is your chance. Telescope manufacturer Unistellar and the SETI Institute have launched the Unistellar Exoplanet Campaign, a citizen science program in which amateur astronomers can help confirm exoplanet candidates spotted by NASA’s Transiting Exoplanet Survey Satellite (TESS).  TESS uses the so-called transit method to spot…

Rare diamonds suggest water lurks much deeper in Earth's interior than scientists thought

A rare type of diamond may suggest that water can penetrate deeper into Earth’s interior than scientists previously thought.  Though more than 70% of our planet is covered with water, there is also water in minerals more than 200 miles (322 kilometers) underground, including in the upper mantle, the semi malleable layer that the crust…

Missing element for life may be present in ocean of Saturn's moon Enceladus

The ocean inside Saturn’s moon Enceladus may be enriched with phosphorus, an important element for life as we know it, new research reveals. Phosphorus is a vital component of life’s biochemistry. For instance, it joins with sugars to provide a “backbone” to DNA, bonding the four nucleobases to the double helix. Phosphorus is also used…
