The monster black hole at the center of our galaxy may be unleashing huge, gassy explosions — and now, astronomers think they’ve pinpointed the exact spot where that superheated gas is spilling into the Milky Way. Acting like a gargantuan exhaust vent, the newly discovered feature is a bright region of X-ray energy that’s nearly … Read more
The NASA’s JWST telescope has discovered what could be the earliest star clusters in the universe. JWST spotted the five proto-globular clusters — swarms of millions of stars bound together by gravity — inside the Cosmic Gems arc, a galaxy that formed just 460 million years after the Big Bang. The Cosmic Gems arc gets … Read more
The sun is on the verge of a significant event: a magnetic field reversal. This phenomenon happens roughly every 11 years and marks an important stage in the solar cycle. The shift in polarity indicates the halfway point of solar maximum, the height of solar activity, and the beginning of the shift toward solar minimum. … Read more
The James Webb Space Telescope has discovered the oldest and most distant supernova ever seen — a stellar explosion that took place when the universe was just 1.8 billion years old. The ancient starburst was uncovered among 80 others in a patch of sky that, from our perspective on Earth, is about the width of … Read more
A planet beyond the solar system that has been compared to Spock’s homeworld Vulcan in the Star Trek franchise may have been nothing more than an illusion caused by a jittery star. The extrasolar planet or “exoplanet” (a term for a planet outside of our solar system) was proposed to orbit a star called 40 … Read more
A private Japanese company has taken the world’s first close-up photo of an individual piece of space debris, by parking another satellite next to it in orbit. This orbital photo op is the first step in an ongoing mission to capture and destroy potentially hazardous pieces of space junk that are clogging up our sky. … Read more
Astronomers have long believed that the ice giants Uranus and Neptune are rich in frozen water. However, a new study suggests they may also have tons of methane ice. The findings could help solve a puzzle about how these icy worlds formed. Much about Uranus and Neptune remains unknown. These ice giant worlds have had … Read more
About one in every 12 stars may have swallowed a planet, a new study finds. Previous research had discovered that some distant stars possess unusual levels of elements, such as iron, which one would expect to make up rocky worlds such as Earth. This and other evidence suggested that stars may sometimes ingest planets, but much remained uncertain … Read more
Nearly four years after NASA’s OSIRIS-Rex spacecraft collected a sample from an asteroid, scientists are finally revealing the intriguing composition of the space rock. Among them, the near-Earth asteroid, known as Bennu, contains a surprising reservoir of a mineral called magnesium phosphate. These bright-white particles sprinkled in a sea of Bennu’s dark rocks is a … Read more
Many maps of the solar system make it look as though everything in space moves in perfect, concentric circles. Planets orbit the sun, and moons orbit the planets. So that must be the case for everything in space, right? Not quite. Orbits form all sorts of shapes. “Planets and other bodies rarely go around in … Read more
