When NASA scientists first observed a particular radio burst from the sun in August 2025, there was nothing unusual about it. But then the radio burst kept going. Typically, solar radio bursts like these last a few hours to days. But this one was different. By the time it was over, the radio burst had lasted 19 days—far exceeding scientists’ expectations and the previous record, which lasted just five days.
On Thursday, NASA issued a Request for Proposal (RFP), seeking industry collaboration for the Mars Telecommunications Network.
Maps can show more than just where things are—they can also show how things change. New maps of artificial light reveal a planet that has been reshaping its nights through patterns of brightening and dimming.
Researchers have developed a mathematical method that enables more precise calculations of the most economical travel routes between the orbits of celestial bodies. To demonstrate this method, they calculated a more efficient path between Earth’s and the moon’s orbits than any previously described in the scientific literature. The study is published in the journal Astrodynamics.
Spain, one of the few places in the world where a total solar eclipse will be visible in August, has begun preparations for an event it hopes will shift tourism away from the beaches and toward the countryside.
We may be more in the dark about dark matter than previously thought, according to a new analysis of distant galaxy clusters. Yale astrophysicist Priyamvada Natarajan, a leading theorist on the nature of black holes and dark matter, says new observational data conflicts with certain assumptions about cold dark matter (CDM)—unseen, slow-moving particles that are inferred by their effect on gravity—and may prompt a fundamental rethinking of dark matter by scientists.
An international team of researchers has developed new stellar and supernova models to explain the mysterious elemental abundance patterns left by billions of supernova explosions around the Perseus constellation, which have been difficult to explain with conventional theoretical models, reports three recent studies published in The Astrophysical Journal.
“I feel like I got the ship back on course from the least secure disastrous chaotic border to the most secure border this country has ever seen,” Michael Banks said
Near-infrared light is invisible to humans. And yet, under the right conditions, the human eye can perceive it. Researchers from Poland’s International Center for Translational Eye Research (ICTER) have now shown that the efficiency of this phenomenon depends not only on the laser pulse itself, but also on two highly specific factors: the beam diameter and the precise focusing of light on the retina. The research is published in the journal Optics Letters.
Scientists have discovered a galaxy as it was 13 billion years ago, 800 million years after the Big Bang. It contains possible evidence of the universe’s first stars and is one of the most chemically primitive galaxies observed to date.
A NASA spacecraft chasing a rare metal asteroid swings past Mars this week for a gravity boost, snapping thousands of pictures as practice for the main encounter in 2029.
Billions of years ago, a young spiral galaxy began to grow in a crowded part of the universe. It pulled in gas and small companion galaxies, slowly building up the bright central region and sweeping spiral arms we see today.
There’s a new space race to the moon, and this time the ambitions are not just to visit but to stay. NASA’s Artemis program aims to establish a long-term human presence on the lunar surface in the 2030s. China, India, Japan and a number of private companies all have lunar mission programs of their own.
If you could take an apple and break it into smaller and smaller parts, you would find molecules, then atoms, followed by subatomic particles like protons and the quarks and gluons that make them up. You might think you hit the bottom, but, according to string theorists, if you keep going to even smaller scales—about a billion billion times smaller than a proton—you will find more: tiny vibrating strings.
