Nice to meet you too lil’ man (gender neutral)

Welcome, To TRAPPIST-1 F

DOGDAYS FANMADE FAMILY BASED ON REAL STARS BECAUSE STARS ARE SO COOL AND I LOVE THEM SO MUCH

[netmassimo]

An article published in the journal "Nature Astronomy" reports a possible reconstruction of the system of the ultra-cool dwarf star TRAPPIST-1 that led to the current configuration of its seven rocky planets. A team of researchers examined their orbits and in particular their orbital resonances, concluding that the planets formed in two steps in a protoplanetary disk divided into two parts. Initially, this led to the formation of two planetary subsystems and only later did planetary migrations occur with influences between various planets that led to the current situation.

I love these so much fr

I designed Sailor Senshi for the Trappist-1 system! I know they should have their own unique uniform, but I just felt like drawing the standard Solar System one

[sunlaire]

I love the Astronomy tag because it ranges from people posting their pictures of the moon and stars to people infodumping about the latest TRAPPIST-1 exoplanet studies, 5k words, no editing

The passion and wonder experienced and shown differently from person to person makes me emotional actually. Its really cute

TRAPPIST-1 - This is a whole star system but I'm counting them all. Absolutely magical place with seven planets around a star just barely larger than Jupiter. The entire system fits within the distance from Sol to Mercury. 3(!) of the planets are in the habitable zone, and all are roughly earth-like. They are so close to each other that you could see the other planets in their skies. It is older than our own solar system. It's just so much.

Phoenix A - The central black hole of the Phoenix Cluster. The sheer size of this thing makes me cry.

Quasi-stars (Black Hole Stars) - Does this count? They're theoretical, but whatever. Potentially the largest stars to have ever existed. Their cores would have been black holes, but maintained equilibrium between gravity and the black hole's outward radiation pressure. It's wild.

Einstein Cross - A gravitationally-lensed quasar forming a cross shape - you see the same image of it in 4 different positions due to light bending around a foreground galaxy!

The Pillars of Creation - It's a classic, but this is still one of my favourite things I've ever seen. There's something so emotional about images of this.

There's so much more I could put in here that it's genuinely so hard to pick five lmao

TRAPPIST-1

The star appears to have many stellar spots (colder regions of its surface, similar to sunspots) and flares. The exoplanet TRAPPIST-1 b, the closest planet to the system’s central star, can be seen in the foreground with no apparent atmosphere.

The exoplanet TRAPPIST-1 g, one of the planets in the system’s habitable zone, can be seen in the background to the right of the star. The TRAPPIST-1 system contains seven Earth-sized exoplanets.

Un articolo pubblicato sulla rivista "Nature Astronomy" riporta una possibile ricostruzione del sistema della stella nana ultrafredda TRAPPIST-1 che ha portato all'attuale configurazione dei suoi sette pianeti rocciosi. Un team di ricercatori ha esaminato le loro orbite e in particolare le loro risonanze orbitali concludendo che i pianeti si sono formati in due fasi in un disco protoplanetario diviso in due parti. Inizialmente ciò ha portato alla formazione di due sottosistemi planetari e solo successivamente vi sono state migrazioni planetarie con influenze tra vari pianeti che hanno portato alla situazione attuale.

The James Webb Space Telescope has unveiled that the TRAPPIST-1 exoplanet appears to lack an atmosphere, but the answer to this mystery might be connected to its host star.

The James Webb Space Telescope has unveiled that the TRAPPIST-1 exoplanet appears to lack an atmosphere, but the answer to this mystery might be connected to its host star. Churning magnetic activity on the surface of TRAPPIST-1’s red dwarf star is interfering with the JWST’s efforts to determine whether any of the orbiting planets are habitable.

James Webb Space Telescope's first spectrum of a TRAPPIST-1 planet

In a solar system called TRAPPIST-1, 40 light years from the sun, seven Earth-sized planets revolve around a cold star.

Astronomers obtained new data from the James Webb Space Telescope (JWST) on TRAPPIST-1 b, the planet in the TRAPPIST-1 solar system closest to its star. These new observations offer insights into how its star can affect observations of exoplanets in the habitable zone of cool stars. In the habitable zone, liquid water can still exist on the orbiting planet's surface.

The team, which included University of Michigan astronomer and NASA Sagan Fellow Ryan MacDonald, published its study in the journal The Astrophysical Journal Letters.

"Our observations did not see signs of an atmosphere around TRAPPIST-1 b. This tells us the planet could be a bare rock, have clouds high in the atmosphere or have a very heavy molecule like carbon dioxide that makes the atmosphere too small to detect," MacDonald said. "But what we do see is that the star is absolutely the biggest effect dominating our observations, and this will do the exact same thing to other planets in the system."

The majority of the team's investigation was focused on how much they could learn about the impact of the star on observations of the TRAPPIST-1 system planets.

"If we don't figure out how to deal with the star now, it's going to make it much, much harder when we look at the planets in the habitable zone—TRAPPIST-1 d, e and f—to see any atmospheric signals," MacDonald said.

Webb mide la temperatura de un exoplaneta rocoso por primera vez

El Telescopio Espacial James Webb ha medido la temperatura de un exoplaneta rocoso por primera vez, encontrando que un “primo” de la Tierra probablemente carece de atmósfera, dijeron investigadores el lunes. Cuando se descubrió el sistema Trappist-1 en 2017, los astrónomos estaban emocionados ante la perspectiva de que algunos de sus siete planetas rocosos, que son más o menos similares a la…
