Test your knowledge of Japan's boldest leaps into the cosmos with a quiz that explores JAXA's missions, milestones, and the science shaping humanity's future among the stars.
He-Man prepares to renew hostilities with Skeletor in a live-action reboot of the toy-inspired cartoon. But does he still have the power?
One feature of the Solar System that doesn't require a complex explanation is the cratered surfaces of some of the planets and moons. These surfaces have been pummeled by impacts, and on some bodies, these impacts are defining features. The craters tell the tale of our Solar System's history.
Additive manufacturing, also known as 3D printing, has a proven track record for reducing waste and efficiently producing made-to-order tools and components. For years, NASA has been testing the technology aboard the International Space Station (ISS) to investigate how it may increase astronauts' self-sufficiency. This is especially true of missions far from Earth, where opportunities for resupply are few and far between. With their latest experiment, the JPL Additive Compliant Canister (JACC), NASA demonstrated another application: 3D printing space antennas.
The night sky, adorned with countless stars, has served as a canvas for human imagination and storytelling for millennia. Across cultures, patterns of stars, known as constellations, have been linked to rich tapestries of mythology, helping ancient civilizations to understand the cosmos, track time, and pass down cultural narratives.
The Japanese company Space One will launch its Kairos rocket for the third time ever today (March 3), and you can watch it live. Kairos failed on its two previous liftoffs.
The galaxy NGC 941 was imaged by the Subaru Telescope at the summit of Maunakea, Hawai'i.
"TIC 120362137 is currently the most compact known 3+1-type quadruple star system."
The stable Solar System we see around us today took time to develop. Not only did it take time for planetary orbits to stabilize, but planetary atmospheres also needed time to evolve. In fact, planetary orbits and evolving atmospheres work together to determine what a solar system eventually looks like, and photoevaporation drives the process.
Known as ASTERIS, the AI network removes noise from images to reveal features a full magnitude fainter than before.
The world's first commercial space telescope has released its first image as it begins its journey to help track nearby stars that might host habitable exoplanets.
Ever since physicist Freeman Dyson first proposed the concept in 1960, the “Dyson sphere” has been the holy grail of techno-signature hunters. A highly advanced civilization could build a “sphere” (or, in our more modern understanding, a “swarm” of smaller components) around their host star to harvest its entire energy output. We know, in theory at least, that such a swarm could exist - but what would it actually look like if we were able to observe one? A new paper available in pre-print on arXiv, and soon to be published in Universe from Amirnezam Amiri of the University of Arkansas digs into that question - and in the process discloses the types of stars that are the most likely to find them around.
There are only a few known fields of tektites in the entire world, and scientists just found another in Brazil.
Tonight's blood moon was the last that will be seen over North America until New Year's Eve 2028.
The ice along Antarctica’s ‘grounding lines’ has been largely stable over the past 30 years – but ice has retreated by more than 40 km in some areas, a new study based on satellite data finds.
Superliminous supernovae are miraculous events. For astronomers, they also provide a vital tool for measuring cosmic distances and the rate at which the Universe is expanding. As part of the Cosmic Distance Ladder, these incredibly bright stellar explosions are the "standard candles" for objects billions of light-years away. In a rare event, researchers from the University of Munich, using the Large Binocular Telescope (LBT) in Arizona, witnessed a superluminous supernova 10 billion light-years away that was far brighter than most explosions of its kind.
Using gravitational waves as a measure of the universe's rate of expansion could solve the biggest headache in physics, the so-called "Hubble tension."
Satellite imaging is increasingly important to every field from crop monitoring to poverty reduction. So it’s no surprise that there have been more and more satellites launched to try to meet that growing demand. But with more satellites comes more risk for collision - and the debris field that comes after the collision. A new paper in Advanced in Space Research from John Mackintosh and his co-authors at the University of Manchester looks at how we might use mission design to mitigate some of the hazards of increasing the number of satellites even more.
"The blood moon rises once again! Please be careful, Link."
Aging stars are prolific producers of dust, and the dust plays an important role in the cosmos. Their dust is ejected into the interstellar medium (ISM) where it is taken up in the next generation of stars and planets. This is how stars seed their environments with metals, elements heavier than hydrogen and helium, which are necessary for rocky planets and life to form.
