The researchers used Webb’s MIRI (the Mid-Infrared Instrument) to study four disks — two compact and two extended — around Sun-like stars. All four of these stars are estimated to be between 2 and 3 million years old, just newborns in cosmic time. The two compact disks are expected to experience efficient pebble drift.
Emission Spectrum – Water Abundance: This graphic compares the spectral data for warm and cool water in the GK Tau disk, which is a compact disk without rings, and extended CI Tau disk, which has at least three rings on.
This graphic is an interpretation of data from Webb’s MIRI, the Mid-Infrared Instrument, which is sensitive to water vapor in disks. It shows the difference between pebble drift and.
When the data first came in, the results were puzzling to the research team. “For two months, we were stuck on these preliminary results that were telling us that the compact disks had colder water, and the large disks had hotter.

That''s about the age of our solar system when planet formation was underway. (The solar system''s age is currently 4.6 billion years.) "Nature is clever; it can produce planets in a range of different ways," said Thayne Currie of the Subaru Telescope and Eureka Scientific, lead researcher on the study. All planets are made from material that
5 · The solar system''s several billion comets are found mainly in two distinct reservoirs. The more-distant one, called the Oort cloud, is a spherical shell surrounding the solar system at a distance of approximately 50,000 astronomical units (AU)—more than 1,000 times the distance of Pluto''s orbit. The other reservoir, the Kuiper belt, is a thick disk-shaped zone whose main
By combining multi-wavelength observations with cutting-edge theoretical models, we are able to start piecing together the planet formation process and understand the origins of our own Solar System. Planets, both those within our Solar System and beyond, form in protoplanetary disks, residual material from the star formation phase which
3 · Our little solar system (little in comparison to the galaxy, that is) lies about 30,000 lightyears from the center of the galaxy. Just as moons orbit around planets, and planets orbit around stars, star systems also orbit around the center of the galaxy. Our own solar system is traveling through the galaxy at over 500,000 miles per hour!
A gas cloud located 500 light years away from our solar system is about to become a planet. This process usually takes a few hundred million years, but what if we made it happen much quicker. Millions of years later, this new planet would cool off, and life could form. So sure, we have a shiny new planet, but it probably wasn''t worth it
By taking advantage of the dust-penetrating capabilities of the James Webb Space Telescope''s infrared instruments, designed and built in part by University of Arizona
Solar systems take millions of years to form. They start out as globs of gas and dust that orbit a central star, which itself may also be forming. Gravity and other forces cause material within the disk to collide. If the collision is gentle enough, the material fuses, growing like rolling snowballs.
These observations show a disk composed of two strong spirals, which are likely launched by a forming planet. The planet the U-M team expected to find is a type called a gas giant, planets composed mainly of hydrogen and helium, similar to Jupiter in our own solar system.

Sep. 8, 2020 — New studies of a rare type of meteorite show that material from close to the Sun reached the outer solar system even as the planet Jupiter cleared a gap in the disk of dust and
The newly forming planet, called AB Aurigae b, is probably about nine times more massive than Jupiter and orbits its host star at a whopping distance of 8.6 billion miles – over two times farther than Pluto is from our Sun.
Theories have long proposed that icy pebbles forming in the cold, outer regions of protoplanetary disks -- the same area where comets originate in our solar system -- should
The disk itself is some 14 billion miles across, or about twice the size of Pluto''s orbit in our own solar system. Credit: NAOJ/Subaru Researchers confirm a new forming planet. Apr 5, 2023.
In this artist concept, the young star SZ Chamaeleontis (SZ Cha) is surrounded by a disk of dust and gas with the potential to form a planetary system. Once our solar system looked something like this, before planets, moons, and asteroids formed. The raw ingredients, including those for life on Earth, were present in the Sun''s protoplanetary
Planets form in disks of dust and gas called protoplanetary disks that whirl around a central protostar during its final assembly. Planets form in disks of dust and gas called protoplanetary disks that whirl around a central protostar during its final assembly.
How much time do planets have to form from a swirling disk of gas and dust around a star? A new University of Arizona-led study gives scientists a better idea of how our own solar system came to be. Scientists believe that planetary systems like our solar system contain more rocky objects than gas-rich ones.
"Webb is bringing us closer and closer to a new understanding of Earth-like worlds outside our solar system, and the mission is only just getting started." Although LHS 475 b is closer to its star than any planet in our solar system, its red dwarf star is less than half the temperature of the Sun,
So we have two options: either we find a new model for forming planets close to the searing heat of the parent star, Kepler data demonstrate that while rocky planets inside Mercury''s orbit are missing from our solar system, they are common around other stars, like Kepler-444. When the first systems packed with close-in rocky planets were

What Makes TIC 393818343 c Special?
The Solar system (or solar system) is the home stellar system for human beings and all known forms of life.The solar system comprises the Sun, all the objects gravitationally bound to it, and the heliosphere, an enormous magnetic bubble enclosing most of the known solar system, including the solar wind and the entire solar magnetic field. Objects bound gravitationally to the
How do planets form? When a star first forms, it is surrounded by a disk of swirling gas and dust. Over billions of years, this gas and dust gradually clumps together to form larger and larger objects, eventually becoming a "mature" system of large planets in stable orbits.
Previous observations by the UArizona-led team revealed spiral arms forming in the protoplanetary disk of MWC 758, hinting at a massive planet orbiting its host star. While no new planets were detected in the disk systems during the most recent observations, the sensitivity is groundbreaking, the researchers say, as it allows them to place the
There, the researchers potentially found a planet candidate in the act of forming in a protoplanetary disk -- but it wasn''t the planet they expected to find. "Several simulations suggest that the planet should be within the disk, massive, large, hot, and bright. But we didn''t find it.
