Stars near the center of our galaxy are acting kind of weird. Dark matter may be the explanation. A team of scientific detectives (so to speak) have discovered a potential new class of stars that could exist within a light-year of the Milky Way's center that could be operating according to an unusual mechanism: dark matter annihilation. This process would produce an outward pressure on the stars other than hydrogen fusion, keeping them from gravitationally collapsing—and making them essentially immortal, their youth being refreshed constantly. The findings are published on the arXiv preprint server. Collectively, the dark matter–powered stars would inhabit a new region of a long-established diagram that classifies stars by their temperature and luminosity, placing them away from the so-called main sequence where the vast majority of stars exist.

another paper I love is about how play behaviour, not tool use, is related to brain mass in birds, and how we draw false conclusions about tool use and cognitive ability when we should be considering play behaviour…i just love that and it’s implications actually
Absolutely beautiful! I hope everyone took this in! Makes you think just how small we are. A moment the world comes together as one! That’s true humanity . We will be uploading more amazing photos to this same post. So come back later on and check out our 2024 once in a lifetime eclipse photos.
This is a fascinating cosmic scene captured by Hubble: jets firing out from the rotational poles of a newly-ignited star illuminate gas and dust inside the Orion B cloud, 1,350 light-years away, forming what's called a Herbig-Haro object.

This Zenith Movie was taken on Sol 4001 (2023-11-07) at approximately 8:04 LTST and a solar longitude of 145.03°. (What is this?)
i could never associate myself with any other form of academic aesthetics than chaotic academia. this is literally the only 'aesthetic' i can abide by, because why are there so many books scattered on my bed, i sleep alone on a whole queen size bed but cannot fit in because after a whole day of studying,books.are.everywhere.
and for some odd reason i refuse to arrange them, it somehow makes it harder for me to find them so i just don't, i have the tendency to make the most important notes on scraps of paper??? though i end up collecting all of them and now i have a stash of notes only i can understand because they are so damn context less.
i always wanted to associate myself to dark academia, because omg i wanna be mysterious so bad, but omfg when i start speaking :D there's literally no stopping me.
my hands, ALWAYS STAINED WITH INK, like i'm EMBARASSED so so embarassed, that i'm a legal adult with pen stains on my clothes, blankets, pillow covers, body and what not.
it is not as pretty or put together as it seems when you study, but it's fun, there's fun in learning i literally just had a mental breakdown over physics but it's a privilege, a privilege that the only thing i'm stressing over is acads, we should probably enjoy the process of learning more than raving over the outcomes, hopefully that makes the process more enjoyable and well, easier to an extent.
anyway, it's 5:20 PM and am off for a nap, b-bye :3
Diamonds are a scientist's best friend—if they're studying Earth's inner layers! Natural diamonds form in the Earth’s molten mantle, far deeper than humans have ever drilled. In this video, mineralogist Kate Kiseeva, assistant curator in the Division of Physical Sciences, explains how tiny crystals captured within these diamonds give scientists a direct window into our planet's inner structure.
