Explosion on a White Dwarf Star Observed for the Very First Time

Artist impression of an exploding white dwarf. Credit: University of Tübingen When stars like our Sun run out of fuel, they contract to form white dwarfs. Such dead stars can sometimes flare back to life in a super-hot explosion and produce a fireball of X-ray radiation. A research team from several German institutes including Tübingen … Read more

What will happen to Earendel, the farthest star ever observed? | Science & Tech

Let’s imagine we are in a soccer stadium. Choose your favorite one: mine is the Santiago Bernabéu stadium in Madrid. I’m sitting in my seat as the Real Madrid soccer club tries to make a comeback. The team’s midfielder Luka Modrić has the ball. Something is going to happen! Everyone can sense it. The spectator … 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 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. Astronomers have … Read more

Low-Meat Diets Linked to Lower Cancer Risk, Hints Study of Nearly 500,000 People

A growing number of people are choosing to eat less meat. There are many reasons people may choose to make this shift, but health is often cited as a popular motive. A large body of research has shown that plant-based diets can have many health benefits – including lowering the risk of chronic diseases, such … Read more

Largest comet ever observed bumps Hale-Bopp from pedestal

The Bernardinelli-Bernstein comet, identified in 2021, is officially the biggest comet ever observed. The new record, reported on the preprint website arXiv and now accepted for publication in the journal Astronomy and Astrophysics Letters, bumps the Hale-Bopp comet from the top spot. Hale-Bopp was discovered in 1995 and became visible to the naked eye in … Read more

Physicists Have Observed a Strange New Kind of Transition in Electronic Crystals

As basic science teaches us, changes in temperature can result in phase transitions in materials – like when water solidifies as ice in the freezing cold. However, in some cases the temperature that triggers the change is different depending on whether the material is cooling down or warming up. This is known as a hysteresis … Read more
