How many planets could be in the Kuiper Belt?
A recent study published in the Astrophysical Journal Letters investigates the potential existence of Mars-sized free-floating planets (FFPs)—also known as rogue planets, starless planets, and wandering planets—that could have been captured by ou.....»»
NHTSA probes Honda"s handling of 2023 Accord, HR-V recalls
U.S. auto safety regulators are investigating Honda's handling of a recall from November involving seat belt restraining issues in new car models......»»
Why there may be oceans inside dwarf planets beyond Pluto—and what this means for the likely abundance of life
Earth was long thought to be the only planet in our solar system with an ocean, but it is beginning to look as though there are underground oceans inside even the most surprising icy bodies......»»
Where are all these rogue planets coming from?
There's a population of planets that drifts through space untethered to any stars. They're called rogue planets or free-floating planets (FFPs.) Some FFPs form as loners, never having enjoyed the company of a star. But most are ejected from solar sys.....»»
Daily Telescope: A flying telescope gets photobombed by some planets
It's a bird... It's a plane... It's a telescope. Enlarge / The SOFIA telescope. (credit: Chris Johnson) Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light, a littl.....»»
Stellar murder: When stars destroy and eat their own planets
Our sun is both our best friend and our worst enemy. On the one hand, we owe our very existence to our star. Earth and the other planets in the solar system formed out of the same cloud of gas and dust as the sun......»»
Mapping the best route for a spacecraft traveling beyond the sun"s sphere of influence
The heliosphere—made of solar wind, solar transients, and the interplanetary magnetic field—acts as our solar system's personal shield, protecting the planets from galactic cosmic rays. These extremely energetic particles accelerated outwards fro.....»»
Tesla’s $25,000 car means tossing out Henry Ford"s 100-year-old assembly line
Instead of a large, rectangular car moving along a linear conveyer belt, parts are assembled simultaneously in dedicated areas and then all put together at the end......»»
Schools in the path of April"s total solar eclipse prepare for a natural teaching moment
Seventh-grade student Henry Cohen bounced side to side in time to the Beatles' "Here Comes the Sun" playing in teacher Nancy Morris' classroom, swinging his arms open and closed across the planets pictured on his T-shirt......»»
In a distant stellar system, the JWST sees the end of planet formation
Every time a star forms, it represents an explosion of possibilities. Not for the star itself; its fate is governed by its mass. The possibilities it signifies are in the planets that form around it. Will some be rocky? Will they be in the habitable.....»»
Astronomers conduct first search for forming planets with James Webb Space Telescope
Planets form in disks of dust and gas called protoplanetary disks that whirl around a central protostar during its final assembly. Although several dozens of such disks have been imaged, just two planets have been caught in the act of forming so far......»»
Heat to blame for space pebble demise
The dust of comets fills the space between the planets, collectively called the zodiacal cloud. Still, severe breakdown has reduced that dust in size so much that it now scatters sunlight efficiently, causing the faint glow in the night sky known as.....»»
Secrets of the Van Allen belt revealed in new study
A challenge to space scientists to better understand our hazardous near-Earth space environment has been set in a new study led by the University of Birmingham......»»
Our survey of the sky is uncovering the secrets of how planets are born
When we look out to the stars, it is typically not a yearning for the distant depths of outer space that drives us. When we are looking out there, we are truly looking back at ourselves. We try to understand our place in the unimaginable vastness of.....»»
Researchers develop a new type of frequency comb that promises to further boost the accuracy of timekeeping
Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized timekeeping, the detection of planets outside of our solar system and high-speed optical communication......»»
NASA Armstrong updates 1960s concept to study giant planets
NASA researchers are looking at the possibility of using a wingless, unpowered aircraft design from the 1960s to gather atmospheric data on other planets—doing the same work as small satellites but potentially better and more economically......»»
Study reveals ancient ice may still exist in distant space objects
A paper recently published in Icarus presents findings about the Kuiper Belt Object 486958 Arrokoth, shedding new light on the preservation of volatile substances like carbon monoxide (CO) in such distant celestial bodies......»»
Hubble tracks Jupiter"s stormy weather
The largest and nearest of the giant outer planets, Jupiter's colorful clouds present an ever-changing kaleidoscope of shapes and colors. This is a planet where there is always stormy weather: cyclones, anticyclones, wind shear, and the largest storm.....»»
See planets being born in new images from the Very Large Telescope
Astronomers have peered into the disks of matter from which exoplanets form, looking at more than 80 young stars to see which have planets forming around them......»»
Subaru Telescope discovers the faintest moon around icy giant planets
Using some of the largest telescopes in the world, including the Subaru Telescope, a team of astronomers discovered three new natural satellites orbiting the outermost planets in our solar system—one around Uranus and two around Neptune. One of the.....»»
More planets than stars: Kepler"s legacy
The Kepler mission enabled the discovery of thousands of exoplanets, revealing a deep truth about our place in the cosmos: There are more planets than stars in the Milky Way galaxy. The road to this fundamental change in our understanding of the univ.....»»
