There is a mysterious carbon dioxide and peroxide in Pluto's Charon moon.

Pluto and its moon Charon are very far away from Earth. There is almost no sunlight. And the temperature on their surface is almost zero kelvin. The chemical reactions are thought to be impossible in that distant, strange world. But the signs of CO2 and peroxides show that there are some kind of chemical reactions in those distant worlds. When we think about those distant dwarf planets called "plutoids" we must realize that conditions around and on those dwarf planets are different than on Earth.

In distant worlds near the Kuiper belt, those dwarf planets can collect atmospheres around them. Most of the solar wind particles are ions and anions that the dwarf planet can trap around it. Those particles can form an ion whirl around those small objects. That ion whirl acts similar way as the ion whirl acts around black holes. It forms the ion generator that forms the magnetic field around plutoids. And even if that magnetic field is weaker than around Earth the reaction that forms a magnetic field around Quaoar forms a magnetic field around black holes.

The conditions around Pluto, Charon, and Quaoar are not similar. The reason why Quaoar has a ring system, but Pluto does not is the Charon's and Pluto'smutual gravity effect that denies ring formation. Quaoar is a lone dwarf planet and that means its clear gravity center in its environment.

The thing is that the gas layer or atmosphere around the low-gravity objects is not stable. Things like energy impulses from the Sun or outside the solar system or flyby the large asteroid or cosmic impact can strip that ion curtain from around the dwarf planet. And that's why all dwarf planets in the Kuiper Belt don't have those thin atmospheres. 

Gas pressure around Pluto is <0,01 kPa, but that allows ions and anions to move freely. Ions and anions pull each other together even in low-pressure conditions. That thing can form CO2 and more complicated chemical compounds. 

The thin atmosphere that forms when those objects pull gas and ions around them remains because the solar wind will not blow those atoms and ions away.  The gas pressure is so low that it's hard to reach in the laboratory. That gas and ion layer forms a magnetic field around plutoids. And it causes things like ring systems around those objects. An example of those systems is the dwarf planet Quaoar which has a similar, but smaller ring system than Saturn. 

If those objects are closer to the Sun the solar wind blows them away. In those low-pressure conditions gas and ions are near the quantum condition. In that low-pressure condition ions and anions pull each other together. The weak sunlight gives them the energy to travel against each other. And if as an example the carbon ion faces an oxygen anion that thing can cause a chemical reaction that forms carbon dioxide. The reaction is similar to that on Earth. But some fewer ions and anions participate in it.

The hydrogen-burning supernovas are interesting models.

"Researchers discovered a significant magnesium anomaly in a meteorite’s dust particle, challenging current astrophysical models and suggesting new insights into hydrogen-burning supernovas. (Artist’s concept.)Credit: SciTechDaily.com" (ScitechDaily, Rare Dust Particle From Ancient Extraterrestrial Meteorite Challenges Astrophysical Models) If the star is too heavy when its fusion reaction starts, it can detonate just at that moment, when its fusion starts. If the collapsing nebula is heavy enough, it can form a black hole straight from the nebula. But if the nebula's gravity is too heavy to  form  the blue giant or too  small  it can collapse  straight  into a black hole . If  the forming star is a little bit larger than the blue supergiants. It can explode immediately when the fusion starts.    The theory of hydrogen-burning supernovas consists  model  of the giant stars that explode immediately after their fusion starts. When the...

The ancient galaxy mirrors the Milky Way.

"This image shows the galaxy REBELS-25 as seen by the Atacama Large Millimeter/submillimeter Array (ALMA), overlaid on an infrared image of other stars and galaxies. The infrared image was taken by ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA). In a recent study, researchers found evidence that REBELS-25 is a strongly rotating disc galaxy existing only 700 million years after the Big Bang. This makes it the most distant and earliest known Milky Way-like galaxy found to date. Credit: ALMA (ESO/NAOJ/NRAO)/L. Rowland et al./ESO/J. Dunlop et al.

And the light that comes from that galaxy named REBELS-25 comes from the Universe that is only 700 million years old. The distance to that galaxy is enormous about 236 billion light years. And that means it's a very dista...

Transcendence, or the ability to transcendent thinking may grow in teen's brains.

   "New research has discovered that transcendent thinking, which involves analyzing the broader implications of situations, can foster brain growth in adolescents. This form of thinking enhances brain network coordination, impacting developmental milestones and future life satisfaction. The study emphasizes the need for education that encourages deep, reflective thought, underscoring the critical role of adolescents in their own brain development". (ScitechDaily, Scientists Discover That “Transcendent” Thinking May Grow Teens’ Brains) "Scientists at  USC Rossier School of Education’s Center for Affective Neuroscience, Development, Learning and Education (CANDLE) have discovered that adolescents who grapple with the bigger meaning of social situations experience greater brain growth, which predicts stronger identity development and life satisfaction years later".
