Euclid spacecraft captures largest, most detailed Milky Way center image
The European Space Agency's Euclid space telescope has just unveiled a singular image of the Milky Way's core, encompassing over 60 million stars.
Astronomers Confirm CoRoT-2b's Slow, Non-Synchronous Spin
On the exoplanet CoRoT-2b, a single day lasts three Earth days, while its entire year is a mere 1.
Physicists Detect Black Hole Signals From Cosmic Edge
For centuries, the event horizon of a black hole was considered the ultimate cosmic barrier, a point of no return where even light ceased to exist; now, physicists have heard a whisper from beyond it.
Giant asteroid passes safely; undetected threats remain
A giant asteroid, 1997 NC1, will pass safely within seven lunar distances of Earth on June 27. This event, while benign, highlights that our ability to detect all potential threats before they pass remains imperfect.
Scientists Find Dynamic Dark Energy, Linking Unknowns
In 2024, the Dark Energy Spectroscopic Instrument (DESI) delivered a seismic shock: evidence that dark energy, the mysterious force accelerating the universe's expansion, has lost its presumed constan
Scientists Discover Dark Matter Clusters Forming Around Supermassive Black Holes
In five out of 14 galaxies studied, mass increases were observed moving away from the central black hole that could not be explained by visible matter alone.
Summer Solstice 2026 longest day Northern Hemisphere arrives June 21
At 4:24 A.M. EDT on June 21, 2026, the Northern Hemisphere will officially experience its longest day, a precise astronomical moment marking the zenith of solar illumination. This specific timing, con
Phobos moon: Rapid approach, characteristics reveal origin
Mars' moon Phobos is hurtling towards its demise, nearing the Red Planet at a rate of six feet (1.
JWST reveals exoplanets with diesel smog-like atmospheres
The James Webb Space Telescope, designed to peer into the potential for life beyond Earth, is instead revealing exoplanets that are either bare and rocky or potentially choked by atmospheres filled wi
Origin of Earth's Oceans: Asteroids and Internal Sources
Many carbonaceous chondrite meteorites, the very building blocks of planets, contain between several percent and up to 15% water by mass, locked within their clay minerals, according to Water Reservoi
Large Magellanic Cloud rips Small Magellanic Cloud apart
Stars in the Small Magellanic Cloud are currently hurtling outward at an average speed of 17 kilometers per second, a clear sign of its imminent demise.
Student astronomer finds star system behind repeating cosmic signals
Every 1.4 hours, a binary star system 3,000 light-years away blasts Earth with powerful radio waves and X-rays, a cosmic beacon that was once a complete mystery. Enigmatic long-period radio transients
Uranus moons hold clues to spotting undiscovered planets
In 85 percent of simulated planetary instability scenarios, Uranus' moon system collapsed, yet it stands today as a silent testament to a violent cosmic past.
NASA's 1992 SETI Program Canceled by Congress in 1993
Less than a year after NASA launched its formal SETI program on Columbus Day in 1992, Congress abruptly canceled it.
Psyche probe captures Mars images en route to asteroid
On May 15, 2026, NASA's Psyche spacecraft captured detailed images of the Martian surface and traces of water ice, not as its primary mission, but as a bonus during a critical gravity assist maneuver.
Cosmic Voids Challenge Understanding of Universe's Structure
Our own galaxy, the Milky Way, sits at the very center of a cosmic void spanning an astonishing 2 billion light-years wide, a discovery challenging current understanding of the universe's large-scale
Rogue star blasts through galaxy, reshaping star formation
For the first time, astronomers have directly witnessed a rogue star, traveling at an estimated 2 million miles per hour, rip through the outer arm of a distant spiral galaxy.
