Bizarre quantum properties of black holes -- including their mind-bending ability to have different masses simultaneously -- have been confirmed by physicists.

Twilight observations have enabled astronomers to spot three near-Earth asteroids (NEA) hiding in the glare of the Sun. These NEAs are part of an elusive population that lurks inside the orbits of Earth and Venus. One of the asteroids is the largest object that is potentially hazardous to Earth to be discovered in the last eight years.

A beautiful tapestry of colors, showing the ghostly remains of a gigantic star, was captured in incredible detail with the VLT Survey Telescope, hosted at the European Southern Observatory's Paranal site in Chile.

NASA's InSight lander recorded a magnitude 4 marsquake last Dec. 24, but scientists learned only later the cause of that quake: a meteoroid strike estimated to be one of the biggest seen on Mars since NASA began exploring the cosmos. What's more, the meteoroid excavated boulder-size chunks of ice buried closer to the Martian equator than ever found before -- a discovery with implications for NASA's future plans to send astronauts to the Red Planet.

Seismologists have developed a new method to scan the deep interior of planets in our solar system to confirm whether they have a core at the heart of their existence.

Until now, Mars has been generally considered a geologically dead planet. An international team of researchers now reports that seismic signals indicate vulcanism still plays an active role in shaping the Martian surface.

A recently released set of topography maps provides new evidence for an ancient northern ocean on Mars. The maps offer the strongest case yet that the planet once experienced sea-level rise consistent with an extended warm and wet climate, not the harsh, frozen landscape that exists today.

A new study has shed new light on a mysterious, unpredictable and potentially devastating kind of astrophysical event.

VLA observations revealed that cosmic rays can play an important role in driving winds that rob galaxies of the gas needed to form new stars. This mechanism may be an important factor in galactic evolution, particularly at earlier times in the history of the universe.

As part of NASA's Artemis program to establish a long-term presence on the moon, it aims to build an Artemis base camp that includes a modern lunar cabin, rover and mobile home. This fixed habitat could potentially be constructed with bricks made of lunar regolith and saltwater, thanks to a recent discovery.

Researchers have developed a new approach to balancing the risks and scientific value of sending planetary rovers into dangerous situations.

Scientists found that ancient bacteria could survive close to the surface on Mars much longer than previously assumed. So, if life did, in fact, evolve when the last waters flowed on Mars, it would likely still be there today -- billions of years later.

An Earth-like planet orbiting an M dwarf -- the most common type of star in the universe -- appears to have no atmosphere at all. This discovery could cause a major shift in the search for life on other planets.

The research framework developed, along with observational data from the Webb Space Telescope, will enable scientists to efficiently assess the atmospheres of many other planets without having to send a space crew to visit them physically. This will help us make informed decisions in the future about which planets are good candidates for human settlement and perhaps even to find life on those planets.

Using the James Webb Space Telescope to look back in time at the early universe, astronomers discovered a surprise: a cluster of galaxies merging together around a rare red quasar within a massive black hole. The findings offer an unprecedented opportunity to observe how billions of years ago galaxies coalesced into the modern universe.

Researchers have developed a new way to use femtosecond laser pulses to fabricate the high-precision ultrathin mirrors required for high-performance x-ray telescopes. The technique could help improve the space-based x-ray telescopes used to capture high-energy cosmic events involved in forming new stars and supermassive black holes.

NASA's James Webb Space Telescope has captured a lush, highly detailed landscape -- the iconic Pillars of Creation -- where new stars are forming within dense clouds of gas and dust. The three-dimensional pillars look like majestic rock formations, but are far more permeable. These columns are made up of cool interstellar gas and dust that appear -- at times -- semi-transparent in near-infrared light.

Analyzing more than two decades' worth of supernova explosions convincingly bolsters modern cosmological theories and reinvigorates efforts to answer fundamental questions.

Scientists have compiled 41 solar occultation observations of Saturn's rings from the Cassini mission. The compilation will inform future investigations of the particle size distribution and composition of Saturn's rings, key elements to understanding their formation and evolution.

Astronomers around the world are captivated by an unusually bright and long-lasting pulse of high-energy radiation that swept over Earth Sunday, Oct. 9. The emission came from a gamma-ray burst (GRB) -- the most powerful class of explosions in the universe -- that ranks among the most luminous events known.
