Astronomers calculate that the Oort Cloud may be home to more visiting objects than objects that belong to our solar system.
In 2019, astronomers spotted something incredible in our backyard: a rogue comet from another star system. Named Borisov, the...
Space is getting crowded. Aging satellites and space debris crowd low-Earth orbit, and launching new satellites adds to the collision risk. The most effective way to solve the space junk problem, according to a new study, is not to...

Observations by Japan's Venus climate orbiter Akatsuki have revealed an equatorial jet in the lower to middle...
In a research paper published by The Astrophysical Journal Letters, an international team of astrophysicists, including scientists from the University of Surrey, detail how they discovered a group of stars with different characteristics than their neighbors found in the Milky...
This artist's impression shows a hot Jupiter planet orbiting close to one of the stars in the rich old star cluster Messier 67, in the constellation of Cancer (The Crab). Astronomers have found far more planets like this in...
This young star is breaking out. Like a hatchling pecking through its shell, this particular stellar newborn is forcing its way out into the surrounding Universe.
The golden veil of light cloaks a young stellar object known only as IRAS...
NASA's extensive fleet of spacecraft allows scientists to study the Sun extremely close-up—one of the agency's spacecraft is even on its way to fly through the Sun's outer atmosphere. But sometimes taking a step back can provide new insight.
In...
The birthplaces of planets are disks made out of gas and dust. Astronomers study these so-called protoplanetary disks to understand the processes of planet formation. Beautiful images of disks made with the Atacama Large Millimeter/submillimeter Array (ALMA) how distinct...
For more than a decade, astronomers across the globe have wrestled with the perplexities of fast radio bursts—intense, unexplained cosmic flashes of energy, light years away, that pop for mere milliseconds.
Despite the hundreds of records of these enigmatic sources,...
Stars over eight times more massive than the sun end their lives in supernovae explosions. The composition of the star influences what happens during the explosion.
A considerable number of massive stars have a close companion star. Led by researchers...

Through a computer-simulated study, astronomers at Lund University in Sweden show that it is highly likely that the so-called Planet 9...
