How small can gas engulfed planets get? Well, a large part of that depends on what counts as a gas dwarf. However despite the problem with the definition, this video covers examples of planets that definitely do lean into the territory of being gas dwarfs, such as the Kepler-138 system and HD 110067 system. Still both of those systems among all other mini neptunes found, has planets that likely mostly have water vapor gas instead of hydrogen and helium, so the final exoplanet talked about LHS 1140 b is used as an example of not a planet that is a gas dwarf, but one that potentially has plenty of hydrogen and helium exactly due to the size, mass and likely temperatures present there, and yet no other example of a mini neptune in that temperature range is found so far.

What if I told you there’s a mysterious planet in our Solar System, way beyond Neptune, that’s smaller than our Moon but has a moon of its own? Imagine a world so far away it takes 554 Earth years to complete just one orbit around the Sun. That’s Gonggong, a dwarf planet that breaks all the rules. If you thought Pluto was icy, wait until you see Gonggong—one of the coldest places in the Solar System, which, to scientists' amazement, is actually red! Most people are still in the dark about the true wonders of this fascinating planet. So, join us as we uncover the mysteries of the intriguing Gonggong dwarf planet.
Dwarf planets are among the most intriguing objects in our solar system, and they are even more interesting because they make us question our understanding of what makes a planet. Unlike the familiar planets like Earth or Mars, dwarf planets occupy the outer reaches of our Solar System, often residing in regions filled with icy bodies and debris. Pluto is often the first dwarf planet that comes to mind, but our Solar System is home to other fascinating worlds. Think of Pluto as the more famous cousin who made headlines, but there are several less-known, and some unofficial dwarf planets that are quiet, mysterious relative who lives in the outskirts of the Solar System. One such fascinating world is Gonggong. Unlike Pluto, which takes about 248 years to orbit the Sun, Gonggong's orbit stretches over 554 Earth years. Although it's smaller than Earth's Moon, Gonggong has its own moon, Xiangliu, and an icy surface that makes it one of the coldest places in the solar system. But the story of Gonggong gets more intriguing and mysterious when we consider its unique surface composition, appearance, and strange location in the Kuiper Belt. Keep watching as we explore this fascinating world and why it's not usually mentioned alongside the five IAU-recognized dwarf planets.

Our team has now provided tentative evidence for a sulphur-rich atmosphere on a world that’s 1.5 times the size of Earth and located 35 light years away. If confirmed, it would be the smallest known exoplanet with an atmosphere. The potential presence of the gases sulphur dioxide (SO₂) and hydrogen sulphide (H₂S) in this atmosphere hint at a molten or volcanic surface.

It should be common knowledge by now that the Kuiper Belt, the ring of icy bodies that extends well beyond the orbit of Neptune, is home to some of the strangest objects in our solar system. Within this region are trillions of comets, asteroids, and large planetoids such as Pluto, Eris, and Makemake—a veritable planetary zoo, in short. But one of its strangest oddities of all is probably that represented by what was once known as 2003 EL61, an object capable of summing up in itself some truly unique features.
This distant outpost of the solar system travels in orbit with an average distance from the Sun of about 43 AU, or 6.45 billion km, going from a perihelion of 34.6 AU to an aphelion of 51.6 AU, and taking a whopping 183 years to complete an entire revolution. A decidedly eccentric orbit, but one that nonetheless places EL61 in the category of so-called classical KBOs (Kuiper Belt Objects), which differ from scattered objects—a category to which the more famous Eris belongs, i.e., those KBOs with highly elliptical and highly inclined orbits, probably thrown into their present orbits through gravitational interactions with giant planets.
Geologists have uncovered strong evidence from Colorado that massive glaciers covered Earth down to the equator hundreds of millions of years ago, transforming the planet into an icicle floating in space.
The study, led by CU Boulder, is a coup for proponents of a long-standing theory known as Snowball Earth. It posits that from about 720 to 635 million years ago, and for reasons that are still unclear, a runaway chain of events radically altered the planet’s climate. Temperatures plummeted, and ice sheets that may have been several miles thick crept over every inch of Earth’s surface.
“This study presents the first physical evidence that Snowball Earth reached the heart of continents at the equator,” said Liam Courtney-Davies, lead author of the new study and a postdoctoral researcher in the Department of Geological Sciences at CU Boulder.
Observations from JWST and Chandra reveal a low-mass supermassive black hole that appears to be consuming matter at over 40 times the theoretical limit

Scientists could be wrong about dark energy. But they’re right about gravity, a new study suggests.
Dark energy, the mysterious phenomenon that causes the expansion of the cosmos to accelerate, is widely thought to have had a constant density throughout the history of the universe. But dark energy may instead be waning, researchers from the Dark Energy Spectroscopic Instrument, or DESI, collaboration report November 19 in a batch of papers posted to the project’s website and arXiv.org.
In this context, the discovery of IRAS 04125+2902 b is a big step forward. IRAS 04125+2902 is a modestly-sized star, with a mass about 70 percent of the Sun’s but more significantly it is just 3.3 million years old, having formed out of the Taurus Molecular Cloud.
The planet has a radius 4 percent smaller than Jupiter’s, making it 10.7 times as wide as the Earth, leaving aside questions like whether it shares Jupiter’s polar flattening. Despite being almost as big as Jupiter, its density is much lower, and it has at most 30 percent of our local giant planet’s mass. Over time it is likely to contract and end up smaller than Saturn, and maybe even Neptune.
With a period of just 8.83 days, IRAS 04125+2902 b will already be receiving plenty of heat, despite orbiting a low-mass star, and that will increase as the star moves through its life. Then again, it is likely to be already very hot from the gravitational collapse that has been the main way we have spotted very young planets previously.
Located a staggering 160,000 light-years from us, the star WOH G64 was imaged thanks to the impressive sharpness offered by the European Southern Observatory's Very Large Telescope Interferometer (ESO's VLTI). The new observations reveal a star puffing out gas and dust in the last stages before it becomes a supernova.
The newly imaged star, WOH G64, lies within the Large Magellanic Cloud, one of the small galaxies that orbits the Milky Way. Astronomers have known about this star for decades and have appropriately dubbed it the "behemoth star." With a size roughly 2,000 times that of our sun, WOH G64 is classified as a red supergiant.

A massive collision of galaxies sparked by one travelling at a scarcely-believable 2 million mph (3.2 million km/h) has been seen in unprecedented detail by one of Earth's most powerful telescopes.
The dramatic impact was observed in Stephan's Quintet, a nearby galaxy group made up of five galaxies first sighted almost 150 years ago.
It sparked an immensely powerful shock akin to a "sonic boom from a jet fighter" – the likes of which are among the most striking phenomena in the Universe.
Stephan's Quintet represents "a galactic crossroad where past collisions between galaxies have left behind a complex field of debris", which has now been reawakened by the passage of the galaxy, NGC 7318b.

At the moment, we can't really say precisely what planet is the largest out of the ones currently found. However, there are still candidates for that place and in this video I examine some which have good potential to be the largest such as the newly formed PDS 70 b. I also go over planets for which there is plenty of uncertainty with regards to their huge size but also their existence such as HD 100546 b. This video uses the NASA exoplanet archive to arrive at a list of largest planets found however there are also some problems pointed out with that same list. Density estimates of HAT-P-67 b and Kepler-51 planets are also examined and the potential problem with such density estimates and with that problem with regards to size estimates of exoplanets. The question as to what the limits are in terms of size for gas giants is also examined.
