#SpaceScience #ImageOfTheWeek: Grab your #3D glasses & dive into a river delta on #Mars! 💦 This recent image was taken by @ExoMars_CaSSIS onboard our @ESA_TGO, currently investigating the planet’s atmosphere & mapping subsurface water-ice. #ScienceAtESA 📷esa.int/spaceinimages/…
Our @ESA_TGO is part one of the joint @esa @roscosmos #ExoMars programme. Coming soon is @ESA_MarsRover, set for launch in 2020 and landing on #Mars in 2021 in a quest to look for evidence for life buried underground. esa.int/exomars #ScienceAtESA #Space19Plus
More exciting #MarsRover news to come later this week..! 🔎
We're also thinking even further ahead and beyond #exomars to the possibilities of the future...like bringing a piece of #mars back to #earth for detailed analysis by scientists around the globe #ScienceAtESA #Space19plus esa.int/Our_Activities…

Greetings from @ESA's operations centre in Germany, where we're following the launch of #BepiColombo together with mission experts. The spacecraft are on the launch pad at Europe's #Spaceport in Kourou & in just over 1 hour will blast off into space. Destination: planet #Mercury
#BepiColombo is a collaboration between @ESA and @JAXA_en to explore the innermost planet in our Solar System. For a primer on #Mercury and the mission, here's a useful thread 👇
And for a unique "first-person" account, follow the three spacecraft accounts: @ESA_Bepi, @JAXA_MMO & @ESA_MTM

🔴💦 Our #Mars Express satellite has detected liquid #water hidden under the planet’s south polar ice cap. Full story: esa.int/Our_Activities…
We know from orbiters, landers & rovers that #Mars had a wet past, with its vast dried out river channels & minerals that can only form in liquid #water, but it is not stable on the surface anymore, so scientists are looking underground…
Until now evidence from the #Mars Express radar experiment MARSIS, the first radar sounder ever to orbit another planet, remained inconclusive. A new operating mode generating higher-quality data was needed to seek out better evidence for buried #water...

From an almost perfect Universe to the best of both worlds: final data release of our @Planck mission confirms the standard model of cosmology... but with a few details to puzzle over ➡️ esa.int/Our_Activities…
Planck scanned the sky between 2009 and 2013 to observe the Cosmic Microwave Background, or #CMB, which is the most ancient light in the history of our Universe, emitted only 400,000 years after the Big Bang, and hidden beneath the microwave emission of our Milky Way galaxy
The first @Planck data release, in 2013, revealed the most precise image of the Cosmic Microwave Background ever obtained. Tiny fluctuations of the #CMB temperature in the sky allow scientists to investigate the contents, history & expansion of our #Universe in painstaking detail

Oil drilling and climate change have decimated the Yamal Penninsula of Russia. The devastation they have wrought are the subject of the documentary of tonight's @NatGeoChannel #MARS episode.
/2 @Greenpeace Russia reports that every 18 months, over 4 million barrels of oil spew into the Arctic Ocean from Russian operations.
/3 Oil and gas prospecting in the continental sector of the Russian Arctic began as early as in the 1930s, prison labor was used.

J'ai bien envie de vous faire un joli thread des plus belles images satellite de #Mars.... ça vous tente?
On commence avec une formation dunaire assez incroyable: le champ de dunes de Hagal. Situé un peu en dessous du pôle nord martien, beaucoup y voient une page de morse... :)
Motifs polygonaux au fond d'un cratère... Cette structure est rendue bien visible grâce au givre qui coiffe les crêtes de cette étrange toile d'araignée. mars.nasa.gov/multimedia/mar…

The fascinating question is how many Trump tweets will it take to completely remove from US news coverage the discovery of a “lake of liquid water” on Mars?
Normally, the discovery of a lake of liquid water on a neighboring planet would be newsworthy because IT’S THE BLEEPIN’ DISCOVERY OF WATER ON #MARS!!!!! But, you know, it’s 2018 and Trump said something on Twitter and Michael Cohen this and that and all those porn stars so...
Hello 👋. THEY JUST DISCOVERED A BLEEPIN’ LAKE OF WATER ON #MARS! That is to say, ON BLEEPIN’ MARS THERE IS A BLEEPIN’ 12.5 MILE WIDE LAKE OF WATER. But, you know, what’s important is 👇🏼. Is it too soon to pack my bags? This planet has become unbearable and easily distracted.

1/ Here's a bunch of animated time lapses from active volcanoes around the world.

#VolcanoesFromSpace

Data is from #ESA #Sentinel2 satellites. It's processed with the #Copernicus / @sentinel_hub tools.

You ask why? Because I like looking at images from volcanoes and so do you!
2/ Bogoslof Island is the summit of a submarine stratovolcano in the Bering sea. In 2017 it erupted and the island became MUCH bigger. There's going to be some happy puffin and seals there (the ones that didn't burn in lava flows that is)!

#VolcanoesFromSpace #Sentinel2
3/ Manaro Voui is a shield volcano in Vanuatu. Starting in 2017 and still going today it's continuously erupting. People are evacuated.

Chief Tari One of Ambanga has conducted ceremonial offerings but it seems these have not been accepted.

T-6 days until @CassiniSaturn burns up in the upper atmosphere of #Saturn. It's has flown for 13 years, and will take pics to #GrandFinale
I'll be highlighting my fav images from @CassiniSaturn over the next week in anticipation of the #GrandFinale on Sept 15. Starting with...
1/ @CassiniSaturn launched aboard a Titan IVB/Centaur in a spectacular night-time launch. Oct 15, 1997. 7 year trip to #Saturn #Grandfinale

It's been awhile since I dropped a thread o' #Mars, so let's try something different today...
1. The hues of #Mars' surface are generally thanks to dust cover—or (relative) lack thereof. Lighter areas = dusty, darker = less dusty.
Oh wow, y'all act fast—I will try to keep up! 😝
