Astronomers discover record-breaking star as small as the moon but with more mass than the sun

Astronomers have discovered the smallest yet most massive white dwarf star ever seen.
According to a new study published Thursday in the journal Nature, the "very special" star has a mass greater than that of our sun, all packed into a relatively small body, similar in size to our moon. It formed when two less massive white dwarf stars, which spent their lives as a pair orbiting around each other, collided and merged together. At the end of their lives, the vast majority of stars become white dwarfs, which are essentially smoldering corpses, in addition to being one of the densest objects in the universe alongside black holes and neutron stars. In about 5 billion years, our sun will become a red giant before ultimately suffering the same fate.On May 7, health influencer Paul Saladino, M.D.. posted a video to his X account that promoted feeding "raw dairy" to infants. The post received over 90,000 views and sparked strong backlash before it was removed the following day. Saladino regularly advocates for "animal-based" diets featuring raw milk, including on his TikTok channel where he has over half a million followers.
Everywhere you look, things are getting more complicated. Our phones have over a thousand settings. Showerheads come with apps. Cars have touchscreens. Ovens have touchscreens. "There's no doubt that 'featuritis' is real," said design consultant Jakob Nielsen. "Most of these things are too complicated."
New research is adding to the evidence linking ultra-processed foods to health concerns. The study tracked people's habits over 30 years and found those who reported eating more of certain ultra-processed foods had a slightly higher risk of death — with four categories of foods found to be the biggest culprits.
