- Seeing the early universe secrets via CANUCS surveys JWST's stunning view of galaxy cluster MACS J1149.5+2223, 5 billion light-years away. Over 300 galaxies lens light, warping distant ones into arcs. Spot the "jellyfish" spiral hosting Earendel, the farthest star at 12.9 billion lightyears.
- A cosmic city under construction 🚧 Chandra is catching a proto–galaxy cluster in the act of forming—its X-ray glow tracing shock-heated gas as gravity assembles one of the universe’s largest structures. ➡️: chandra.si.edu/photo/2026/p...
- Coming soon…
- Astronomers have found the earliest, hottest galaxy cluster on record — SPT2349-56, a dense assembly of ~30+ galaxies just ~1.4 billion years after the Big Bang. ➡️: www.space.com/astronomy/ga...
- A new analysis finds that intracluster light — faint starlight between galaxies in clusters — carries signatures of past mergers and interactions. Mapping this diffuse glow helps reconstruct the assembly history of galaxy clusters and the role of cosmic structural growth. ⬇️
- Using data from the JWST, scientists have created one of the most high resolution, detailed maps of dark matter ever produced. The diffuse blue structures trace dark matter halos, mapped via weak gravitational lensing, where visible galaxies are only passengers. ➡️: www.jpl.nasa.gov/news/nasa-re...
- Astronomers have applied a new AI tool called AnomalyMatch to the 35-year Hubble Legacy Archive, scanning ~100 million small cutouts and identifying over 1,300 unusual objects — hundreds previously undocumented, including many interacting and merging galaxies. ➡️: www.stsci.edu/contents/new...
- The most distant confirmed exoplanet detections in the Milky Way come from the SWEEPS survey toward the Galactic bulge. SWEEPS-11 and SWEEPS-04, detected via transits with the Hubble Space Telescope, lie at ~27,700 ly away in the dense, metal-rich inner Milky Way. science.nasa.gov/missions/hub...
- Astronomers have uncovered a giant iron-rich bar hidden inside the iconic Ring Nebula — a structure hundreds of times the size of Pluto’s orbit and containing about a Mars’ worth of iron. Its origin is still a mystery, possibly linked to how the dying star expelled material.
- NOIRLab and the Dark Energy Survey team have released the full six-year Dark Energy Survey dataset, covering hundreds of millions of galaxies and enabling new constraints on dark energy, large-scale structure, and cosmic evolution. noirlab.edu/public/news/...
- I had a funny idea. If I were to make a theory synopsis… I would name it “Trent’s Individual Theory Synopsis” (T.I.T.S.) Thoughts?
- 🔭 A new comet has been discovered! P/2025 W3 (Kresken) was identified by Rainer Kresken (ESA) with the Calar Alto Schmidt telescope using a new camera. The discovery has been officially confirmed by the IAU as part of the CAHA–ESA collaboration. ➡️: www.caha.es/es/noticias/...
- New Hubble images of Baby Stars! The compact nebular region stands out against the stellar background, shaped by radiation and winds from nearby massive stars. These interactions sculpt the gas, trigger collapse in some regions, and erase it in others.
- Protoplanetary disks in visible light. These Hubble views capture young stars still wrapped in the dust and gas that will one day form planets. The dark lanes mark disks seen edge-on, while glowing jets trace material being funneled along magnetic fields. This is mid-process planetary formation.
- Spectacular new images from Hubble! Protostars within a cosmic breeding ground known as the Orion Molecular Cloud.
- Stop. Breath. Give yourself some space from all of your troubles.
- In time… Stars will burn out. Black holes will evaporate. Even matter itself may slowly dissolve into radiation. The end of the universe isn’t a collapse… it’s a fading. And in that silence, the fact that anything ever existed at all becomes the most extraordinary thing of all.
- NASA is targeting no earlier than January 17, to roll out the Artemis II Space Launch System & Orion spacecraft from the Vehicle Assembly Building to Launch Pad 39B at Kennedy Space Center for final preparations, ahead of its crewed lunar flyby mission planned for February-April.
- The JWST has uncovered a new class of point-like distant galaxies that don’t fit existing categories, too tiny and compact to be normal galaxies, yet unlike quasars. Astronomers nicknamed them “platypus galaxies” because of their unexpected mix of features in images and spectra.
- Canadian astronomers used JWST to map Milky Way's evolution via 877 "twin" galaxies from 1.5-10 billion years ago. Chaotic early mergers built central bulge first, then outer disk via interactions—more turbulent than models predicted. From 100-300M to >100B stars today.
- NASA Prepares Artemis Il Crewed Moon Flyby for 2026 🚀 Artemis II will send four astronauts-Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch, and Jeremy Hansen-on a 10-day trip around the Moon, the farthest humans have gone since Apollo 17 in 1972.
- After nearly five years on Mars, NASA JPL engineers confirmed the Perseverance rover can continue operations until at least 2031, covering an additional 37 miles in Jezero Crater.
- Using ALMA and VLA data on protostar SVS 13B in NGC 1333, Astronomers discovered over 400 bow-shaped molecular rings in its jet, each marking a past accretion-driven outburst. These rings serve as chronological markers, with the youngest aligning to a 1991 optical flare.
- New JWST observations reveal what’s happening at the heart of NGC 4486B. This compact elliptical galaxy hosts a double nucleus—now best explained by an eccentric stellar disk orbiting a displaced supermassive black hole. ⬇️

- Four years ago, the James Webb Space Telescope launched—quietly redefining how we see the universe. Here are some of my favorite images from James Webb.
- Every star you see in the night sky may be a sun to someone else.
- “There are more habitable Earth-mass planets in the observable volume of the universe than there are grains of sand on all the beaches on Earth.” - Dr. Avi Loeb.

- The potential dark future of the universe underscores that we live in a privileged time — the brief window when life can thrive, look up to see trillions of stars and galaxies, and know its impermanent place in an ever-changing universe.
- “Our little terraqueous globe as the madhouse of those hundred thousand millions of worlds. We, who cannot even put our own planetary home in order, riven with rivalries and hatreds; are we to venture out into space?” - Carl Sagan
- 🔮HUGE ANNOUNCEMENT!!!🔮 🌌 I’m happy to say that I’M OPENING UP A DISCORD SERVER! 🌌 I was thinking about doing this for a while and I have finally come to a consensus. I wanted to make a space where I can bring all my besties into one place and hang out!🔮 Discord:👇 discord.gg/xqFzJjsg
- “The Earth is the cradle of humanity, but mankind cannot stay in the cradle forever.” — Konstantin Tsiolkovsky
- When I look up at the night sky, I see the stars, but also the future.
- “We are all time travelers journeying together into the future. Let us work together to make that future a place that we can visit.” - Stephen Hawking
- "We are stardust which has taken destiny into its own hands.” - Carl Sagan✨

- One in 200 stars has habitable Earth-like planets surrounding it - in the galaxy, half a billion stars have Earth-like planets going around them - that's huge, half a billion. So when we look at the night sky, it makes sense that someone is looking back at us.
- To celebrate Halloween tradition, I thought about doing an Outlast Stream. Anyone interested in that?

- Quadrillions of other planets are out there, waiting to be discovered. Each with their own unique history, some like our home, others beyond fiction. To visit these far-off places is a dream only our descendants can realize. I can only imagine when that time of stepping on an exoplanet happens.
