Been a while since I posted art here. This is the Ultra-Hot Jupiter WASP-76 (A)b, known for its ferrous rain and glistening skies (citation needed). Collab with @birbbirbbirb1.bsky.social, go check out his page! #Astronomy #Art #Digitalart #Space #Stars #Exoplanets #Planets
WASP-76b and a hypothetical moon around it. Despite this planet being described as having a glory effect, I decided not to include it. Collab with @inverse5040.bsky.social! His post: bsky.app/profile/inve..., check it out! #Astronomy #Space#Planet #Exoplanet

Today’s arXiv day: PALTA-1, an ultracool dwarf (not sure if a very low mass star or a brown dwarf) with a candidate sub-Jupiter-mass planet detected by astrometry. arxiv.org/abs/2610.09965
Astrometric planet search around southern ultracool dwarfs: V. Discovery of the exoplanet candidate PALTA-1 b
We report the discovery of PALTA-1 b, a sub-Jupiter mass exoplanet candidate orbiting the nearby early-L dwarf DENIS-P J1253108-570924 (DE1253-57) located at a distance of ~17 pc. The exoplanet was di...

PUMA-2025 delivered! 🌍🛰️ Over the past two years, every sub-Saharan African country has been equipped with a PUMA-2025 station, enabling national meteorological services to receive and process MTG data distributed via EUMETCast-Africa.
Rest in peace. Her efforts shall be forever remembered by humanity!

Vaalbara is thought to be Earth's earliest supercontinent. It's formed of cratons (stable pieces of continents) up to 3.6 billion years old with palaeomagnetic and asteroid impact traces that line up today. en.wikipedia.org/wiki/Vaalbara Illustrated: olivermcrae.artstation.com/projects/lVb...
Trying something more unique... I've decided to make a project in strawpage where I illustrate stars in the immediate vicinity of the sun. For now there's only 5 stars, but it will receive updates with time. stellarneighbors.straw.page #Astronomy #Space #Stars #SpaceArt

All my current paintings in progress are in their awkward/ugly phase lol, so here is one I did last October! A spooky star-forming region in the Eagle Nebula I named Leviathan’s Wake. I’ll bring back prints at the end of this month 🐉
Can planets emerge from the deaths of stars? 💀 Astronomers looking through Hubble data from 1999 have identified unusual amounts of niobium in the chemical signatures from a white dwarf. 🔭 🧪

On today's arXiv: the eccentricity of the debris disc of Epsilon Eridani arxiv.org/abs/2610.00462 The belt is found to be nearly circular, suggesting it consists of dynamically cold planetesimals that haven't been strongly perturbed. #astronomy #space #star #debrisdisk #EpsilonEridani
How eccentric is the debris disk of epsilon Eridani? ALMA reveals a near-circular belt
The nearby (3.2 pc) K2V star $ε$ Eridani hosts the closest detected debris disk and an exo-Jupiter analog ($ε$ Eridani b). In this work, we reanalyse ALMA Band 6 (1.29 mm) observations of $ε$ Eridani ...

A duel mission to Uranus and Neptune, launched by a single SLS: ieeexplore.ieee.org/document/105... Each probe is ~6.5 tons, plus an Orion 50XL deep space maneuver stage , on a ΔVEGA gravity assist trajectory, arriving after 16 and 18 years respectively.
Some four million years ago, two superstars flew past our neighbourhood: Adhara and Mirzam. Both extremely bright and massive stars, to this day they remain one of the brightest stars in each other’s sky. #ACelestialJournal
As a cold sub-Neptune planet, TOI-6981 b probably has a hydrogen-rich atmosphere which might make its atmosphere resemble our giant planets', so I based its appearance on Jupiter, Saturn, and Neptune. bsky.app/profile/astr...

Inspector Smile is ready for science! 🫡 This is Smile’s first ultraviolet view showing an auroral substorm. With the ultraviolet camera now operational, Smile becomes the first spacecraft since 2008 to capture the full ring of northern lights around the north pole in ultraviolet light. 🔭 🧪 ☀️
Today's arXiv day went almost 6 hours past UTC midnight. I predicted it's going to be a monster. I was right. - Possible mechanism for variable He escape from LHS 1140 b - 2-ary eclipse+phase curve for TOI-2431 b - NEID Earth Twin Survey part 6 - TOI-125 trans. spec - TOI-210 b discovery
