Thank you so much!

I used two filters to produce this image. The one where the rings where visible was the red one, i.e. the longer wavelength. This means the colder things appear in redder colors than the rest

Last night, the JWST observed Uranus for calibration. Even like that the result is awesome, so here you go with my processed image of that observation! 🔭

HD: flic.kr/p/2ry78y3

Observation of Uranus by the JWST. The planet itself appears mostly blue, but the pole, a big patch, is white. Some storms can also be spotted near the pole. The rings of the planet can be spotted in infrared light, so they appear in that image (in orange color).

The best part of processing space telescopes' data is to discover new regions that I didn't even know existed in the first place! 🔭

This is G054.093+01.748, a star forming region in our galaxy, as seen by the JWST recently, located in the Outer Scutum–Centaurus spiral arm.

HD: flic.kr/p/2rxLQyT

A big gas cloud where new stars are being born seen in infrared light. The gas cloud itself appears in red, orange, and violet colours, occupying almost the entire image. Hundreds of dots are spread across the picture, as they are stars in our own galaxy.

La Repubblica published that 60k people were in the streets in Florence, but I believe we were far more than that.

So many Italian cities are rising up for this important cause, and we are all ready to keep going as long as we need to!

There were so many people in the streets in Florence this morning, it was amazing! 🇵🇸✊

All eyes on #3I/ATLAS ☄️

Our Mars Express & ExoMars Trace Gas Orbiter will observe the comet around its closest approach to Mars on 3 October 2025, when 3I/ATLAS will be around 30 million km from the red planet.

Stay tuned and follow esa.int/3IATLAS 🔭🧪

Infographic showing the path of comet 3I/ATLAS, the third known interstellar object to enter our Solar System. It displays the orbits of Earth, Mars and the Juice spacecraft around the Sun, along with key dates and events as comet 3I/ATLAS travels through the inner Solar System in 2025. Coloured and numbered dots mark important observation points by telescopes and spacecraft.

I am bringing your TL some sparkles! 🔭 ✨

This is the NGC-1850 star cluster in the LMC, as seen by Hubble! The number of stars in that part of the cluster is bonkers 🤯

Processing that data was really fun!

An observation of a star cluster by the Hubble Space Telescope. Thousands of stars can be seen in the image, appearing in blue, red, orange or white colors. A blue and white veil of gas goes from the upper left part of the image to the middle down part of it.

Thank you!! 🥲

Thanks! I was just amazed by all the details in the background and it caught my eyes

Some things deserve a focus 🔭

First, the jets created by the formation of new stars, that are sooooo beautiful;

the spiral galaxies in the background that are impressive as well;

and this gravitational lensed background galaxy is a nice touch!

The JWST had a new look into the IC348 star forming region last year, and here's my processed image of that observation! 🔭

IC348 is located some 1,000 light years away from us and is made of hundreds of new stars born there.

HD: flic.kr/p/2ruCvCz

A focus on a star forming region seen in infrared light. Hundreds of white dots, big and small ones, can be seen everywhere in the image as they are stars! A lot of gas can be seen in the image, covering almost every part of it. This gas is what is helping the new stars to be formed there. In the upper left part, multiple jets can be spotted: they are stars being born at this very moment! A lot of background galaxies can also be spotted in the whole image

Here are some things that Charlie Kirk said in his life.

The man is dead, and so it only seems fair to share his legacy by cataloguing the values he spread while alive.

For 58€ a month I can ride on almost any public transport anywhere in Germany. Within a 15 minute walk from my house I can access 4 S Bahn lines, 3 UBahn lines, regional trains (I honestly don’t even know how many of those), 3 tram lines and at least 4 city bus lines (probably more).

This is a big one! 🔭

A few weeks ago, I worked with a team of astronomers, led by Anne-Marie Lagrange, on SPHERE and MIRI data. It was about the TWA7 exoplanet, something you probably read about in June.

They asked me to produce another image, so here's the result:

A star, which has been blocked by a black circle, surrounded by three rings (the smaller one is the nearest, the biggest one the farthest). A red dot can be spotted on the right side of the second ring. The rings are in orange colour.

And here's the ESA's version: esawebb.org/news/weic2512/

Evidence for a sub-Jovian planet in the young TWA 7 disk - Nature

Using the James Webb Space Telescope's Mid-Infrared Instrument, a study reports evidence for a direct detection of a cold, sub-Jupiter-mass planet in the disk of the star TWA 7.

TWA7 is a small star located ~111 light years away, and with the MIRI data, they spotted what is most probably a sub-Jovian exoplanet! This is the red dot on the right, located 52 AU away from the star. 🔭

You can also see three rings around the star, that I focused on during my processing time.

The same image but with indication: the rings are highlighted by dashed-lines; a scale on the bottom shows that the exoplanet is located some 50+ AU from the star and the farthest ring has a diameter of 200 AU; the North is indicated on the top and the East is on the left.

Starting next Monday and for the next 4 years, I will be a PhD Researcher at the EUI in Florence!

As I arrived yesterday, I decided to visit, for the first time, the historic centre of Florence, and it's just incredible!! I can't wait to see even more

Hello! Yeah Flickr changed their conditions to download full resolution pictures, the owner of the picture needs to have a Pro account (which I can't afford right now).

I've uploaded it on my GDrive: drive.google.com/file/d/1ksMx...

Of course you'll need to credit me properly but I trust you!
