Possibly the weirdest planet yet discovered?

Newfound world 2M1510 (AB) b appears to orbit not one but two stars...and they are actually failed stars, known as brown dwarfs...and the planet orbits sideways, in a unique up-and-down polar orbit.

https://www.eso.org/public/news/eso2508/ #space #science #astronomy #nature

Left: This image, taken in visible light, shows 2M1510 AB, a pair of brown dwarfs orbiting each other. The two brown dwarfs, A and B, are seen as a single source in this image, but we know there are two of them because they periodically eclipse each other. When monitoring their orbits, astronomers found perturbations that can only be explained by the gravitational tug of an exoplanet circling both brown dwarfs in a perpendicular orbit. This system contains a third brown dwarf, 2M1510 C, which is located too far away to be responsible for these perturbations. Right: This is an artist’s impression of the exoplanet 2M1510 (AB) b’s unusual orbit around its host stars, a pair of brown dwarfs. The newly discovered planet has a polar orbit, which is perpendicular to the plane in which the two stars are traveling.

This proposal essentially ends U.S. leadership and dominance in space research and space-based astronomy.

"NASA’s science budget could be cut nearly in half under an early version of President Donald Trump’s budget proposal to Congress, a move that would terminate billions of dollars’ worth of ongoing and future missions."

Concerns about the potential impact of obtrusive #SpaceAdvertising on the night sky continue to generate media stories. Here's one from @Tagesspiegel (auf Deutsch) for which I was interviewed recently.

#Space 🌌 is a far more logical, sensible place to do #fusion, because that’s where it wants to happen anyway. In 📆 2027, we’re going to send a small part of #Sunbird in #orbit. The first #functional Sunbird will be ready four to five years later. Sunbird could deliver #cargo to #Mars 🔴 in under six months https://edition.cnn.com/science/nuclear-powered-rocket-pulsar-space-spc/index.html

"You’re going to see more ‘city-killer’ asteroids, but fret not, MIT astronomer says" by KTLA Los Angeles - #Asteroid#2024YR4 is a useful example of what we're likely to see more often as astronomers get better equipment to locate rocks that have always been out there but previously passed unseen in the dark. Observation of an asteroid's orbit should look like this each time. https://ktla.com/news/nationworld/city-killer-asteroids-more-common/ #astronomy#PlanetaryDefense#PlanetaryDefence#LowFlyingRocks #space

"Asteroid 2024 YR4 is going to miss Earth, but the story doesn’t end there" by @arstechnica / @sciguyspace - The orbit of #Asteroid#2024YR4 has been narrowed down enough to know it will not hit Earth. Get used to more asteroids being evaluated as potential threats. The good news is that humanity is increasingly able to find these threats which were already out there. Don't be a dinosaur.🦕🦖🌠 https://arstechnica.com/space/2025/02/asteroid-2024-yr4-may-be-a-dud-but-we-will-soon-find-many-more-threats/ #astronomy#PlanetaryDefense#PlanetaryDefence#LowFlyingRocks #space

"A Near-Miss with a City-Killer Asteroid Highlights Gaps in Earth’s Defenses" by @SciAm - Increasing capabilities to search for the next wayward #asteroid will mean recurring news like #2024YR4 where a threat is evaluated for potential collision course with Earth. At some point, we will find one headed here. Planning and test exercises try to become prepared for what to do when we know one is coming. https://www.scientificamerican.com/article/how-planetary-defenders-planned-to-stop-that-city-killer-asteroid/ #astronomy#PlanetaryDefense#PlanetaryDefence#LowFlyingRocks #space
