Now that the chances of impact are reducing to next to nothing we can focus on how cool this #asteroid flyby will be! Hopefully space missions can investigate up close like RAMSES for #Apophis... or maybe it will hit the moon which would be fascinating for impact studies! #PlanetSci

A #cats and #space post. Perfect!

The second-largest sea of liquid methane on Saturn's moon Titan, Ligeia Mare, based on radar data captured 18(!) years ago today. I miss working on Cassini daily, and I daydream of Dragonfly cruising Titan's hazy skies. science.nasa.gov/resource/vas...

Had an interesting talk about Arrokoth in a recent #CometInterceptor meeting. Will be fascinating to compare the appearance of this Kuiper belt object in situ with an incoming comet from there or the Oort cloud #PlanetSci

We are kicking off our Bluesky account: follow us for news on @esa.int's launches, projects and developments in space transportation. Updates on the Vega and Ariane rockets 🚀, Space Rider and more.

Some good news: looks like the chance of impact from 2024 YR4 has dropped.

Astronomers will turn the James Webb Space Telescope towards asteroid 2024 YR4 next month. The most powerful telescope ever launched into space will provide a more accurate estimate of the size of the asteroid, which has a very small chance of impacting Earth in 2032. blogs.esa.int/rocketscienc...

Bathed in the sunset light, this image shows steady progress in the construction of ESO’s ELT! At first glance, the steel structure might look modest in size, but it's already more than 50 metres high and 41 metres wide 🤯 More: https://www.eso.org/public/images/potw2506a🔭 🧪 📷 ESO

Very cool! #HeraMission is a #Martian moons mission as well as an #asteroid mission! (Although maybe those are the same thing, who knows?! 😛) #Planetsci

For those of you connecting with us for the first time here, we've put together an overview of our most impressive cosmic views from recent times. Buckle up for a journey through the Universe 👇 1/9 🔭🧪

This is the nucleus of a comet. Comet 67P/Churyumov-Gerasimenko, photographed by ESA's Rosetta spacecraft. The streaks are jets of gas, dust, and ice venting from the nucleus as the Sun's heat warms the comet. This material comprises the comet's coma and tails. Credit: ESA/Rosetta/NAVCAM

Asteroid #2024YR4 update!Good to know JWST is on the case 🙂

Interesting stuff, particularly for me in the very low strength estimates of rubble pile asteroids. Will be fascinating to see what @esa.int's Hera sees of the resulting crater!

Good morning, Bluesky! Welcome to the European Space Agency's mission control centre! If you’re not familiar with what we do here, let’s get you up to speed with a look back at an action-packed 2024…

Big news! We’ve just launched some new accounts 🎉 Give them a follow: 🔭 @esascience.esa.int 🧑‍🚀 @esaexploration.esa.int 🚀 @esatransport.esa.int 🌍 @esaearth.esa.int 📡 @esaoperations.esa.int ⚙️ @esatechnology.esa.int 🛰️ @esaconnectivity.esa.int Stay tuned for exciting things ahead! 💙✨

Very informative thread on the threat of asteroid 2024 YR4, current observing plans and what's going to happen in the future, including a nice plot explaining the Torino scale

In recent years, #NASAWebb has provided closeups of planets with rings in our solar system. Planets’ rings are active, dynamic structures that undergo daily temperature shifts, seasons, and even form moons: webbtelescope.pub/3CuFTWT 🔭 🧪

What a perfect polygon! These are surface features caused by thermal stress fracturing or desiccation, and might also be occurring on #comets like 67P! #planetsci
