ESA satellites track progress on Paris Agreement goals

ESO Top News - Fri, 11/07/2025 - 5:52am

As the United Nations COP30 climate change conference convenes in Belém, Brazil, the world's attention will turn to the heart of the Amazon rainforest – a region that symbolises both hope and concern in the fight against climate change.

Once considered one of Earth's most vital carbon sinks, the Amazon is now showing troubling signs – satellite observations reveal that parts of this vast ecosystem are no longer absorbing carbon dioxide as they once did. In some areas, the forest has even become a net source of carbon emissions.

The "Anti-Weather" Of Venus

Universe Today - Fri, 11/07/2025 - 5:39am

Conditions on Venus’ surface have largely remained a mystery for decades. Carl Sagan famously pointed out that people were quick to jump to conclusions, such as that there are dinosaurs living there, from scant little evidence collected from the planet. But just because we have little actual data doesn’t mean we can’t draw conclusions, and better yet models, from the data we do have. A new paper from Maxence Lefèvre of the Sorbonne and his colleagues takes what little data has been collected from Venus’ surface and uses it to valid a model of what the wind and dust conditions down there would be like - all for the sake of making the work of the next round of Venusian explorer easier.

Insects on the space menu

ESO Top News - Fri, 11/07/2025 - 3:00am

Long before humans reached orbit, insects had already shown they could handle the hurdles of spaceflight. Light, highly adaptable and nutritionally rich, these resilient animals present an attractive option for European researchers studying reliable food sources for long-duration missions.

Astronomers Observe a Black Hole in Another Galaxy Tearing a Star Apart

Universe Today - Thu, 11/06/2025 - 9:08pm

New study reveals, for the first time, a tidal disruption event (TDE), where a black hole tears apart a star, occurring outside the center of a galaxy that produced exceptionally strong and rapidly evolving radio signals. This rare discovery shows that supermassive black holes can exist and remain active far from galactic cores, challenging current understanding of where such black holes reside and how they behave. The event’s delayed and powerful radio outbursts also suggest previously unknown processes in how black holes eject material over time.

It Looks Like All Mini-Neptunes Aren't Magma Oceans After All

There are no mini-Neptunes in our Solar System, yet they seem to be one of the most common types of exoplanets out there. Previous research shows that these planets are magma oceans. But new research based on JWST data shows that many of them may actually have solid surfaces.
