The members of Expedition 73-"B" settle in and get busy conducting science research on board the International Space Station.
In this quiz, you’ll test your cosmic knowledge by matching each moon to the planet it calls home.
There's a gap in black hole masses, and experts believe here is where 'lite intermediate black holes' reside.
Deep-field images from NASA's James Webb Space Telescope revealed 300 unusually energetic early galaxy candidates, offering new insights into how the universe formed and evolved over 13 billion years ago.
Astronomers discovered a star-triggered explosion shaping its dusty disk, revealing a far more chaotic and intense environment than previously thought.
The Milky Way galaxy glows alongside the zodiacal light over the Cerro Tololo Inter-American Observatory (CTIO) in Chile.
The European research project called "gEICko" aims to develop satellites that can literally stick to space junk and drag it safely out of orbit. The secret lies in synthetic materials that mimic the microscopic structures on the feet of gecko, which allow these remarkable reptiles to cling to virtually any surface using molecular forces called van der Waals interactions.
Imagine the entire universe suddenly blazing with light in a flash that lasted just a brief moment in time and then vanishing, leaving behind the most massive black holes ever discovered. This dramatic scenario forms the heart of a new theory that could solve one of astronomy's biggest mysteries about supermassive black holes and how they got so enormous so quickly after the Big Bang.
The connection between greenhouse gases and space weather might seem surprising, but it illustrates just how interconnected Earth's atmospheric layers really are. While carbon dioxide warms the lower atmosphere by trapping heat, it has the opposite effect in the thin regions of the upper atmosphere, roughly 300-400 miles above Earth's surface. At these extreme altitudes, carbon dioxide actually cools the atmosphere by radiating heat directly into space, causing the air to become significantly less dense over time.
Two exotic new theories suggest dark matter could be either made from tiny black holes or formed by Hawking radiation at the cosmic horizon.
Saturn glows through the evening near the Andromegasus Dipper. Venus and Jupiter, drawing apart, still light the dawn dramatically. The Moon joins them.
The Event Horizon Telescope (EHT) established a reputation worldwide in 2019 when it released the first-ever image of a black hole. This was made possible by the science of Very Long Baseline Interferometry (VLBI), a technique in which multiple instruments collect light to create a complete picture of what an object looks like. In this case, the image was of the supermassive black hole (SMBH) at the center of Messier 87, a massive galaxy 55 million light-years from Earth. This was followed by images of the relativistic jets emanating from two bright galaxies, and of Sagitarius A*, the SMBH at the center of the Milky Way.
Our Moon is a seismically active world with a long history of quakes stretching back to its early history. It turns out those quakes can and will affect the safety of permanent base structures for anybody planning to explore and inhabit the Moon. That's one conclusion from a study of quakes along the Lee-Lincoln fault in the Taurus-Littrow valley where the Apollo 17 astronauts landed in 1972. “The global distribution of young thrust faults like the Lee-Lincoln fault, their potential to be still active and the potential to form new thrust faults from ongoing contraction should be considered when planning the location and assessing stability of permanent outposts on the Moon,” said Smithsonian senior scientist emeritus Thomas R. Watters, lead author of the paper.
In this quiz, you’ll explore the weird, wonderful, and sometimes surprising world of space cuisine. Can you tell which foods have actually made it to orbit?
Recently, acting NASA Administrator Sean Duffy reportedly suggested a U.S. reactor would be operational on the moon by 2030.
The four spacecraft of NASA's PUNCH mission have successfully locked in place in Earth orbit.
The James Webb Space Telescope has revealed many wonders of the early universe, but few discoveries have puzzled astronomers more than some mysterious "little red dots." These tiny, brilliant galaxies appear scattered across deep space images like cosmic breadcrumbs, challenging everything scientists thought they knew about how galaxies formed in the early universe.
When global events set our minds to wondering if humanity has what it takes to persist, it's natural to wonder about other worlds, other life, other intelligent species, and if those others might be better suited to survive whatever Great Filters they face. Those are fanciful thoughts, but there's an underpinning of nuts-and-bolts thinking to them. It starts with identifying which planets in habitable zones around other stars might actually be habitable.
As another world around TRAPPIST-1 shows no signs of an atmosphere, astronomers urge us not to give up hope for an Earth-like atmosphere on one of the other worlds in the system.
The U.S. Space Force's powerful new military radar system designed to detect and track objects in distant orbits above Earth has passed an initial key test.
