Here's an ESA video uploaded on September 11 concerning about how the ESA archives its' Earth observation data:

Join us as we enter ESA's Heritage Missions data archive, which stores Earth observation data dating back to the 1970s.

ESA preserves this historical record from past satellite missions, which provides valuable information for long-term studies. The datasets from these missions are not only preserved, but continuously improved over time with reprocessing activities that make them compatible with products acquired by more recent missions and apply new processing algorithms that can improve the accuracy and quality of the products.

The presenter, Malì, is wearing an ESA t-shirt in the video, which is available for sale on the ESA online shop: https://www.esaspaceshop.com/earth-ou...https://www.youtube.com/redirect?ev...-relief-t-shirt-for-adults.html&v=O1J2kbaWS6g

Study inspects unusual behavior of an X-ray binary

Study inspects unusual behavior of an X-ray binary

Astronomers from the National Central University in Taiwan have investigated an unusual superorbital period variation of an X-ray binary known as 4U 1820-30. Results of the study, published September 13 on the preprint server arXiv, could help us better understand the nature of this system.

A recently identified comet is growing “brighter than expected” and could be the most impressive one of the year for skygazers, astronomers say.

Tsuchinshan-Atlas, discovered in 2023 and simply known as A3, has been making its way into the inner Solar System and is now visible in several regions of the world.

‘Brighter than expected’ comet may be visible without telescope this week

Skygazers in southern hemisphere are already sharing pictures of comet A3 on social media

I cannnot wait for the comet Flyaway, this has been said to potentially be the next Hale Bopp (in terms of magnitude). I am going to monitor it closely. But comets are funny things look at what happened to ISON for example.

You might want to add a comma after comet, FighterJock, as you just implied Flyaway is a comet.

Anton Petrov has a video out about how the JWST has detected a very distant galaxy that should be too faint to image:

Hello and welcome! My name is Anton and in this video, we will talk about a discovery of a very bizarre distant galaxy ( JADES-GS-z13-1-LA ) that produces light that shouldn't be visible

Here's a PBS Eons video about when Earth ate a planet:

Where did our unique moon come from? It turns out that lunar rocks brought back by Apollo astronauts are a clue, pointing to the origin of our closest cosmic companion, an origin even stranger than you might imagine…

ESO telescope captures the most detailed infrared map ever of our Milky Way

Astronomers have published a gigantic infrared map of the Milky Way containing more than 1.5 billion objects ― the most detailed one ever made. Using the European Southern Observatory’s VISTA telescope, the team monitored the central regions of our Galaxy over more than 13 years. At 500 terabytes of data, this is the largest observational project ever carried out with an ESO telescope.
