How does #ESAEuclid observe matter across the unverse - specifically if it doesn't emit light? It's the use of light deflection by matter, "gravitational lensing".

#ESA has released a new explainer video about how this works and how #Euclid's Flagship Simulations are used to simulate and quantify what is being measured:

Maximum eclipse from Liberty Hill, Texas. Quite a nice partial eclipse, and the clouds stayed away!

80mm ED Refractor and Nikon D750 camera.

Has #Rosetta touched your life?

Did it inspire you to pick up a different subject at university or made you call a pet 'Philae'? Was your research informed by Rosetta data or have you created art (or a cake!) based on Rosetta images?

My colleagues at #ESA are creating an online exhibition to showcase your stories - you can submit words, images, videos, audio files or links to published material (see link where/how to submit):

This is one or two irregular dwarf galaxies. They’re known as the Small Magellanic Cloud, but recent studies suggest it may be a pair of galaxies lined up behind each other.

You can just make out some nebulae inside. Those are giant star forming regions, caused by the Milky Way trying to pull the SMC to bits with its gravity.

The bright spots are globular clusters, a bit closer to home. The top one is 47 Tucanae, the smaller one on the left is NGC362.

Nice, clear skies last night so the Seestar got fired up in the yard and imaged some bright Milky Way nebulae.

1. Triffid Nebula (50 mins)
2. Helix Nebula (1 hr 40 mins)

Great time of year for southern hemisphere folks to catch the bright nebulae as they are high in our sky.

Here's the Eastern Veil again, with stars. But there's a lot more fine detail in the starless version.

Breaking, from the Red Planet

The Mastcam-Z team at ASU has just released a new batch of 45 Martian sols of images, captured by Perseverance, and treated with their natural color processing. Check out these otherwordly wonders!

Final sprint for the #ESAEuclid #galaxyzoo galaxy shape classification campaign. The set of 3500 galaxies requiring each 25 people's classification is almost but not yet fully complete.

So you can still participate: go to https://galaxyzoo.org and start classifying!

We will use these data to train an automated #machinelearning algorithm, which in turn will be able to classify millions and millions of #Euclid galaxies!

Poetry in motion 🌕🛰️🌏

A week ago today, ESA's Jupiter-bound JUICE mission was approaching Earth, a day after its close flyby of the Moon.

You'll have seen some of the monitoring camera shots that @stim3on & I processed, & here's the chaser: a timelapse of both flybys that I set to some brilliant music by Gautier Acher 🎶

The full 4K version has been released by ESA here: https://www.esa.int/ESA_Multimedia/Videos/2024/08/Juice_s_lunar-Earth_flyby_the_movie/?1

Still a very active sun. By all traditional measures we're still headed toward solar maximum in '25, but when we had the Aurora Borealis as far south as Mexico a few months ago some did speculate that it might have come early. I guess we'll see.
