💥 @esa and @NASA space telescopes further investigated #GRB221009A, the famous gamma-ray burst which might be the brightest since human civilisation began.
A mystery remains about the object that exploded to create the GRB. Astronomers used @ESA_Webb and @HUBBLE_space to look for the aftermath of the explosion, and found... nothing. 2/4
There is lots of follow-up work to be done as astronomers continue to search for the remains of the exploded star. One thing they will look for is traces of heavy elements like gold, thought to be produced in such massive explosions 👉 esa.int/Science_Explor…#ExploreFarther 3/4
Scientists presented new findings about #GRB221009A at the High Energy Astrophysics Division meeting of the American Astronomical Society @AAS_Press in Waikoloa, Hawaii. youtube.com/c/AASPressOffi…

Philae left its imprint in billions-of-years-old ice, revealing that the comet’s icy interior is softer than #cappuccino froth or the foam in a bubble bath or on top of waves at the seashore ☕️🛁🌊#RosettaLegacy (photo courtesy @AstroEmz)
A new #comet was discovered last month by amateur astronomer Micheal Mattiazzo from Australia. Just, he did not look at the sky to do so. He inspected images from #SOHO, our Solar and Heliospheric Observatory.
Here is a photo of the comet from 2 May 👇
Today, it reached its closest approach to Earth at around 85 million km, and it is headed towards its closest point to the Sun on 27 May. It is now faintly visible to the naked eye. Will it become brighter?
It can be extremely difficult to predict the behaviour of comets, but scientists are hopeful that Comet SWAN will remain bright enough to see as it continues its journey. If it survives, star gazers should look for it near the bright star Capella in the constellation of Auriga ☄️
@ESA_TGO@esa@NASA@isro@roscosmos Did you know that you can find out what the #weather is on #Mars? Landers & rovers report the local weather while orbiters keep an eye on global atmosphere developments including cloud formations and dust storms☁️🌪
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 👇
🔴💦 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...
