In a new study, astronomers reported discovering an exomoon, a super-sized moon orbiting a Jupiter-sized planet beyond our solar system. They made this discovery after analyzing archival data, indicating the possibility of more exomoon discoveries to come.
David Kipping and his Cool Worlds Lab at Columbia University said, “Astronomers have found more than 10,000 exoplanet candidates so far, but exomoons are far more challenging. They are terra incognita.”
New Insights Into Seasons On A Planet Outside Our Solar System – Eurasia Review
Imagine being in a place where the winds are so strong that they move at the speed of sound. That's just one aspect of the atmosphere on XO-3b, one of a class of exoplanets (planets outside our solar system), known as hot Jupiters.
Hot Jupiters are massive, gaseous worlds like Jupiter, that orbit closer to their parent stars than Mercury is to the Sun. Though not present in our own solar system, they appear to be common throughout the galaxy.

For the first time, researchers have studied a series of events beginning 14 million years ago that caused a still-expanding cosmic bubble to envelop Earth's galactic neighborhood, forming all the nearby stars, a statement explains.
Scientists have suspected the giant bubble's existence for decades. However, astronomers only recently have observed the net, its shape, and how far it reaches.
Interstellar Probe Proposed to Explore the Solar Neighborhood - Sky & Telescope - Sky &
A unique mission concept known as Interstellar Probe would venture beyond the solar system and probe our neighborhood environment.
An exciting mission spanning the next half century of space exploration may leave Earth on a path out of the solar system in the next decade.
A NASA Probe Went and Booped the Sun - The Atlantic
Kelly Korreck is still thinking about the time her spacecraft flew into the sun, how one moment, the probe was rushing through a stormy current of fast-moving particles, and the next, it was plunging somewhere quieter, where the plasma rolled like ocean waves.
"This is a totally cool place to go—well, I guess, hot place to go," Korreck, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, told me. "We've touched plasma and gas that actually belongs to the sun."
'Cool' hidden exoplanet the size of Jupiter discovered in distant solar system - Daily Star
The massive exoplanet is thought to be 379 light years away, reports Space.com , which makes it closer to Earth than many other newly discovered planets.
But it still means that what we can see now actually happened while the English Civil War was raging.
Evidence of zodiacal light on other habitable worlds | Astronomy.com
One of the most coveted sights for skygazers is the zodiacal light, a tall cone of whitish light that climbs the mid-latitude sky before dawn in autumn and at twilight in the spring.
In research presented at the virtual 239th Meeting of the American Astronomical Society last week, Jian Ge of Shanghai Astronomical Observatory and Chinese Academy of Sciences — whose team included three high school students — described other solar systems where data suggest there
The Sun once had rings just like Saturn, study reveals
HOUSTON, Texas — The Sun once looked a lot more like Saturn — and it may be the reason our planet isn’t bigger than it is, a new study reveals.
Their study finds these rings actually prevented Earth from getting too big and developing a massive gravitational pull which would have stunted the growth of organisms. Such a gravitational attraction would have also made devastating asteroid impacts more frequent.
A Star Passed too Close and Tore Out a Chunk of a Protoplanetary Disk - Universe Today
When it comes to observing protoplanetary disks, the Atacama Large Millimetre/sub-millimetre Array (ALMA) is probably the champion. ALMA was the first telescope to peer inside the almost inscrutable protoplanetary disks surrounding young stars and watch planets forming.
According to new observations, it looks like chaos and disorder are part of the process. Astronomers using ALMA have watched as a star got too close to one of these planet-forming disks, tearing a chunk away and distorting the disk’s shape.
