We're only starting to awaken to the passage of interstellar objects through our inner Solar System. So far we know of three, but there are bound to be many more. Do they pose an impact threat to Earth? from Universe Today https://ift.tt/ITCBzyi via IFTTT

The planets in our Solar System host hundreds of moons, so it seems likely that planets in other solar systems do, too. New research examines the likelihood of rocky planets around M dwarfs having exomoons, and it doesn't look good. They don't last long enough for them to give life a helping hand like Earth's moon has. from Universe Today https://ift.tt/RhD1XWV via IFTTT

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. from Universe Today https://ift.tt/T91kt7n via IFTTT

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. from Universe Today https://ift.tt/Q82P7Ea via IFTTT

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. from Universe Today https://ift.tt/tWjJ5U7 via IFTTT

The Euclid Space Telescope found some stars hiding in thick gas and dust in the Orion Molecular Cloud Complex. They're inside a so-called dark cloud named LDN 1641. from Universe Today https://ift.tt/oJsKtyh via IFTTT
