🔴💦 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...
The #Mars Express radar investigation finds a subsurface feature spanning about 20km across under a 1.5km thick layer of ice & dust, interpreted as a buried pond of liquid water, which could be laden with salty, water-saturated sediments...
Maybe there are more of these hidden pools of #water?! This exciting discovery will contribute to our understanding of the evolution of #Mars, the history of water on our neighbour planet and its habitability potential. Full story: 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

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

I published a study last week on where Premier League clubs source their money and what they spend it on by reviewing the clubs’ cash flow statements over the last decade. Today I do a similar exercise on Championship clubs – where the picture is very different.
In the 10 years between 2008 and 2017 Championship clubs had over £2.8 bln of available cash with the vast majority of financing £2.5 bln coming from their owners (loans £1.9bln and shares £0.6 bln)
So an incredible 87% of Championship clubs’ cash came from owner financing with just 7% from operating activities. This is in stark contrast to the Premier League with 54% from operations and 42% from owners. There was also £41m from (net) player sales & £45m from bank balances.

THREAD - How about a bunch of blog posts on #Space and #Astronomy? Yes, I have more than you can imagine - especially since these are really just #physics topics. Hold on - because this is going to be a bit large.
2/ Here is an answer to my fav astronomy question EVER - "What would the phases of the moon look like if the moon was a cube?" wired.com/2015/09/moon-c…
3/ The great thing about the cube moon question is that it really tests if students understand phases of the moon rather than just recalling factual stuff. Here is my python model of a cube and spherical moon

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.

The ICE manual for undercover agents describes how agents & informants are allowed to break the law & can use "proceeds" from illegal businesses to fund their own operations in the field. Profits can also be paid to other agencies and foreign governments unicornriot.ninja/2018/icebreake…
ICE can also use profits from illegal business activity by undercover agents and/or informants to buy evidence, to pay themselves overtime, and pay for travel expenses unicornriot.ninja/2018/icebreake…
ICE provides cover to undercover agents and informants, as well as fake businesses for use during infiltration, using a variety of methods. One passage reveals how they are provided with fake social security numbers by the Social Security Administration unicornriot.ninja/2018/icebreake…

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! 😝
