Astronomers Find a Wandering Planet With a Magnetic Field Millions of Times Earth’s

SIMP’s surface temperature exceeds 1,500°F—hot for a planet without a star. Key Takeaways _____ IMP: A Wandering Magnetic Marvel Astronomers have identified a remarkable rogue planet, SIMP J01365663+0933473, which roams the Milky Way without a parent star. This enigmatic object lies just 20 light-years away and boasts a magnetic field 4 million times stronger than […]

Light from behind a Black Hole Observed for the First Time, Confirming Einstein’s Theory

All our science, measured against reality, is primitive and childlike – and yet it is the most precious thing we have. – Albert Einstein (1879-1955) TL;DR Astronomers have observed light bending around a black hole, a phenomenon predicted by Einstein’s theory of general relativity. By studying X-rays from a black hole in the Zwicky 1

Saturn’s rings are surprisingly young, forming within the last 100 million years

Saturn’s rings are only about 100 million years old, meaning they formed long after the first dinosaurs and mammals walked the Earth. Key takeaways _____________________________ Exploring Saturn’s Rings During NASA’s Cassini spacecraft’s Grand Finale, the craft daringly dove between Saturn and its rings, gathering groundbreaking insights about the planet and unveiling the unexpected youthfulness of

Scientists estimate that there are at least 36 intelligent alien civilizations in the Milky Way

New Estimate Suggests Only 36 Active Extraterrestrial Civilizations May Exist in Our Galaxy TL;DR New research suggests there could be as few as 36 active extraterrestrial civilizations in the Milky Way galaxy. Based on the idea that intelligent life evolves over 5 billion years, scientists from the University of Nottingham estimate that the nearest alien

Gut Bacteria Found to Soak Up Toxic Forever Chemicals

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) have the nickname ‘forever chemicals’ thanks to their persistence in the environment. While a handful of bacteria are known to mop up these insidious compounds, it’s unclear whether any of our own microflora hide such a talent. A new study by an international team of researchers has shown how several species of

First Visual Evidence Confirms A Star Exploded Twice

All supernovae are massively energetic stellar explosions. The classic supernovae are massive stars that explode near the end of their lives, leaving behind either a neutron star or a black hole, and a remnant made of expanding gas and dust. But supernovae are not all the same. Some occur in binary systems, and they’re called Type 1a supernovae.

Curiosity Cracked Open a Rock on Mars And Discovered a Huge Surprise

A rock on Mars spilled a surprising yellow treasure after Curiosity accidentally cracked through its unremarkable exterior. When the rover rolled its 899-kilogram (1,982-pound) body over the fragile lump of mineral in May last year the deposit broke open, revealing yellow crystals of elemental sulfur: brimstone. Although sulfates are fairly common on Mars, this represents the first
