Scientists discovered three dwarf galaxies dancing together in a rare gravitational trio near the Andromeda Galaxy, revealing new secrets about how small galaxies survive in cosmic neighborhoods. The finding shows that even in the vast universe, companions stick together.
NASA's Hubble Space Telescope just completed the most detailed star map ever created of our neighboring Andromeda galaxy, measuring 200 million individual stars across two-thirds of its disk. The breakthrough gives scientists an unprecedented window into how galaxies like our own Milky Way evolve over billions of years.
Scientists using Hubble telescope data have mapped 200 million stars in the Andromeda galaxy, revealing it's peacefully winding down after a burst of star formation 2 billion years ago. The discovery offers fresh insights into how massive galaxies evolve over cosmic time.
For the first time, astronomers may have watched a massive star collapse into a black hole without exploding. The star, once visible from backyard telescopes in the Andromeda galaxy, simply faded into darkness over several years.
For the first time, astronomers watched a massive star disappear and transform into a black hole without the usual supernova explosion. The discovery in the Andromeda galaxy could help scientists find countless hidden black holes across the universe. #
Stargazers worldwide caught stunning photos of the Perseid meteor shower peak, just hours after a rare total solar eclipse. The double celestial treat delivered hundreds of shooting stars across perfectly dark August skies.
Scientists have discovered that the Milky Way and neighboring galaxies rest inside a massive sheet of dark matter millions of light-years across. This breakthrough solves a mystery that has puzzled astronomers for nearly a century.
Two astronomers stood before the Smithsonian in 1920 to argue about the size of our universe. One of them would be proven spectacularly right, changing everything we know about our cosmic home.
True Anomaly's autonomous spacecraft just completed its toughest mission yet, proving it can track and maneuver around objects in orbit. The success clears the path for critical Space Force defense missions launching over the next 18 months.
Two private space companies just completed one of the most complex satellite missions in modern history, proving that the future of space reconnaissance belongs to commercial innovators. Their success opens the door to faster, smarter ways to keep America safe in orbit.
NASA's Hubble Space Telescope has revealed a rare galaxy caught in the act of transformation, where a supermassive black hole is fundamentally changing how stars are born. The discovery helps scientists understand how galaxies evolve from bustling star factories into quiet cosmic neighbors.
A researcher has mapped out an ambitious strategy to keep Earth habitable long after our Sun dies in five billion years. The plan involves giant sunshades, antimatter, and moving the entire planet without ever leaving home.
NASA's Hubble Space Telescope photographed a gorgeous spiral galaxy twirling toward the center of a massive cluster 60 million light-years away. The image reveals a cosmic dance that's been unfolding for millions of years.
Scientists just confirmed our home galaxy grew from a massive collision with another galaxy 12 billion years ago, revealing how the Milky Way became the cosmic neighborhood we know today. The discovery shows our galaxy has been growing by absorbing neighbors since nearly the beginning of time.
The Department of Defense is investing in a groundbreaking spacecraft that can refuel satellites in orbit, potentially extending their lifespan indefinitely. Quantum Space will deliver the game-changing vehicle in just two years.
Astronomers discovered footage of a massive star quietly collapsing into a black hole without the usual supernova explosion, hiding in plain sight for a decade. The discovery challenges everything scientists thought they knew about how stars die.
NASA's Nancy Grace Roman Space Telescope is heading to Florida for launch this September, eight months ahead of schedule. The observatory will map huge sections of the universe at once, revealing the invisible forces shaping our cosmos.
NASA's Hubble telescope is mapping millions of stars near our galaxy's center to help the new Roman Space Telescope discover thousands of hidden planets starting this fall. This cosmic teamwork will reveal entire worlds we never knew existed.
