How Robots Are Helping Telescopes Build Better Maps of the Universe
Modern telescopes use thousands of tiny robotic positioners to target distant stars and galaxies, but mechanical limits can leave surprising gaps in cosmic surveys. Researchers have now developed a simulation tool that acts like a flight si
CHIME Detects an Ancient Signal From the Early Universe
The CHIME radio telescope has detected an extremely faint signal from neutral hydrogen billions of years ago, using its own observations rather than relying on traditional galaxy surveys. The breakthrough offers a new way to map the univers
Euclid Reveals a Mysterious Stellar System 9,100 Light-Years Away
The Euclid space telescope has uncovered an extremely faint stellar system near the Fornax dwarf galaxy. Astronomers are now trying to determine whether it is an unusual star cluster or something even more intriguing—a tiny galaxy orbiting
Scientists Find New Clues That Enceladus Could Support Life
Saturn’s moon Enceladus is becoming an increasingly fascinating target in the search for extraterrestrial life. New research suggests that its underground ocean and icy plumes could naturally concentrate chemical clues, while laboratory exp
The Strange Galaxy That Reveals Millions of Years of Cosmic Activity
Astronomers have uncovered an extraordinary radio galaxy stretching nearly four million light-years across. Its unusual structure contains clues to a complex history of activity around its central supermassive black hole, offering a rare gl
Stanford’s New AI Could Revolutionize Autonomous Spacecraft Navigation
Stanford researchers have developed an AI “world model” designed to help spacecraft navigate and dock autonomously. Instead of following only fixed instructions, the system learns from experience and simulates possible futures. The approach
How Supermassive Black Holes Control the Fate of Entire Galaxies
Supermassive black holes may control the growth of entire galaxies. New research shows that narrow plasma jets can travel hundreds of thousands of light-years, reaching the gas surrounding galaxies and creating directional regions of glowin
James Webb Detects Water, Methane and Ammonia on a Surprisingly Cold Exoplanet
The James Webb Space Telescope detected water, methane, and ammonia in the atmosphere of HATS-6 b, a giant exoplanet orbiting a surprisingly small star. Its enormous size and unexpectedly cold temperature could challenge current theories of
Mars Has a Purple South Pole — Here’s Why
Mars’ south pole is revealing surprising purple, pink, and red landscapes shaped by volcanic minerals, dust, and seasonal carbon dioxide ice. Giant cliffs like Thyles Rupes also reveal how Mars’ cooling crust evolved without Earth-like plat
Could This Hot Super-Earth Reveal Earth’s Molten Past?
James Webb has found a rocky super-Earth that appears to retain an atmosphere despite orbiting extremely close to its star. Its unexpectedly cool dayside may reveal how gases survive on scorching lava worlds—and could offer clues about Eart
Did the Universe Twist Ancient Light? Scientists Test a Strange Cosmic Signal
Did the universe twist its oldest light as it traveled across billions of years? Scientists have developed a new calibration method to test cosmic birefringence and separate genuine cosmic signals from telescope errors. Using Planck data, t
JWST Finds Heavy Elements in the Universe’s Earliest Galaxies
The James Webb Space Telescope has found evidence that early galaxies were already producing and spreading heavy elements just 500 million years after the Big Bang. Carbon and oxygen detected in distant galaxies suggest the young universe b
Scientists Develop a New Way to Search for Dark Matter
Researchers from the University of Hong Kong and Beijing Normal University have developed a new way to investigate dark matter by simulating its behavior as a wave. Their 3D models of “fuzzy” dark matter reproduced the gravitational lensing
Astronomers Capture a Neutron Star Feeding on a Massive Blue Star
Astronomers using the XRISM X-ray observatory have captured rare details of a neutron star feeding on the powerful stellar wind of a massive blue hypergiant 13,000 light-years away. The observations reveal plasma racing toward the neutron s
Starship’s Next Giant Leap: SpaceX Moves Closer to Orbital Flight
SpaceX’s Starship enters another critical phase as its 14th flight attempts to push the massive spacecraft closer to true orbital operations. The mission combines next-generation Starlink satellites with crucial tests of speed, gravity, reu
Listening to the Stars: The First Radio Signal From an Exoplanet
Tune in to explore a milestone in astronomy: for the first time, scientists have detected direct radio signals from an exoplanet, Beta Pictoris b. Learn how researchers used distant quasars as cosmic GPS to measure the massive planet's inte
Mars Had Multiple Water Worlds, NASA Rover Reveals
NASA’s Perseverance rover has uncovered evidence that water transformed Mars in at least three distinct episodes. In Jezero Crater’s Margin Unit, the rover found igneous rocks containing carbonates and silica—clues to ancient groundwater, a
Could Tiny Solar Sails Become the Future of Space Travel?
Cornell students have successfully tested tiny solar sails in orbit using miniature ChipSats and 3D-printed spacecraft. Their Alpha CubeSat and Sailing to the Stars missions demonstrated how sunlight can propel ultra-light spacecraft, while
Could Venus Have Swallowed Its Own Moon?
A new study suggests Venus may once have had a moon that eventually spiraled inward and crashed into the planet. Simulations show that Venus’s slow rotation could make moons unstable, offering a possible explanation for its unusual evolutio
How Moon Collisions Could Change the Search for Alien Life
Computer simulations show that massive collisions can reshape icy moons without necessarily destroying their hidden oceans. Larger moons may even retain enough heat to thicken their subsurface oceans, while smaller moons could lose insulati
Could the Universe Be a Giant Cosmic Loop?
Scientists are searching for clues that the universe may be finite and globally connected rather than infinite. By analyzing the cosmic microwave background and galaxy patterns, the COMPACT collaboration is looking for repeating structures
Could Quantum Computers Finally Detect Dark Matter?
Researchers have proposed using entangled superconducting qubits to search for axions, hypothetical particles that could explain dark matter. The idea is to detect tiny quantum-state rotations caused by these elusive particles and extract t
Astronomers Discover a Galaxy That Doesn’t Rotate Like the Others
Hubble has captured a striking view of NGC 4698, a spiral galaxy about 55 million light-years away in the Virgo Cluster. Unlike most galaxies, its central bulge rotates almost perpendicular to its main disk. Astronomers believe this unusual
Scientists Find Thousands of Organic Molecules Inside Ancient Meteorites
Researchers have uncovered tens of thousands of organic compounds inside the Murchison and Aguas Zarcas meteorites using the world’s highest-resolution mass spectrometer. Atomic force microscopy also revealed rare images of individual extra
Scientists Discover a Universal Rule for Black Hole Jets
New research suggests that black holes of vastly different sizes follow the same rule when launching powerful radio jets. By studying stars torn apart by black holes, scientists found that jets appear when the feeding rate falls below a cri
The Youngest Exoplanet Ever Found Is Still Being Born
Elias 2-24 b has officially become the youngest known exoplanet, at less than a million years old. Located about 450 light-years away, this Jupiter-sized world is still forming and appears to be gathering material from its surroundings. Its
Earth’s Center Is Moving: NASA Reveals a Hidden Seasonal Wobble
NASA researchers have developed a more precise way to track tiny seasonal shifts in Earth’s center of mass. Ocean tides, rainfall, snowfall, and atmospheric changes subtly move the planet’s mass, causing the geocenter to wobble. By combinin
