Researchers have found an odd Milky Way planet orbiting over and under the poles of two failing stars. Star systems arise from flattened, spinning disks of gas and dust, with materials gathering along the plane of the disk, forming planets, moons, and asteroids around a newborn star. Only sixteen exoplanets had ever been verified to circle a binary pair; all of those planets orbit in the plane of the stars’ orbits of one another, not over the poles. The elusiveness of these planets makes this find very fascinating.

Researchers knew of the two objects this odd planet orbits before they came upon it. They originally identified the do-si-doing pair using the SPECULOOS Southern Observatory in Chile in 2018, only to find they were brown dwarfs, failed stars insufficient in mass to ignite. The system began to look stranger once they zoomed in on the binary pair with the Very Large Telescope at the Paranal Observatory in Chile.

Scientists Find First Polar Planet in Bizarre Double-Brown-Dwarf System

According to the report, scientists have found the strangest planetary system yet observed, featuring the first-ever “polar planet” and a planet that orbits two stars. Better known as “failed stars,” brown dwarfs—stellar bodies that fail to gather enough materials to attain the mass required to start the fusion of hydrogen to helium in their cores—are the parent stellar bodies of exoplanet 2M1510 (AB). This discovery is the first solid evidence of such a fully formed system.

Exoplanet 2 M1510 (AB) b is a stellar body known as a “failed star” because it fails to gather enough matter to reach the mass needed to start the fusion of hydrogen to helium in its core. The chance of stellar bodies having a binary partner increases with mass, making a double-brown-dwarf star system pretty surprising.

Rare Eclipsing Brown Dwarf Pair Hosts First Known Polar-Orbit Planet

This is only the second pair of eclipsing brown dwarfs ever discovered, meaning one of the brown dwarfs eclipses the other, as seen from Earth’s vantage point. Team member Amaury Triaud of the University of Birmingham said that “a planet orbiting not just a binary, but a binary brown dwarf, as well as being on a polar orbit, is rather incredible and exciting.”

The discovery was incidental, since the observations were not aimed at such a planet or orbital arrangement. This realization usually helps one to understand what is sensible on the interesting planet we live on.

Webb Telescope Uncovers Hidden Active Galactic Nuclei

An obscured population of huge and massive black holes has been revealed by the James Webb Space Telescope. This discovery could bridge the gap between quasars and the Little Red Dots. These are active galactic nuclei galaxies (AGNs), overlapped or blurred by active blackholes, occupied by dust. Their bright nature makes them detectable in spite of the dust surrounding them. However, during December 2022, astronomers found a new type of AGN that they called Little Red Dots, because they appear as tiny, fat red spots.

Connection of AGN with Quasars is Still a Mystery

For more than a decade, the study has been led by Dale Kocevski, an astronomer at Colby College. Their team includes scientists like Jorryt Matthee, an astrophysicist at the Institute of Science and Technology, who contributed to the understanding of little dots and their connection with quasars. Their connection is still a mystery that prompts them to find the objects with properties in between.

The Old Universe Abundantly Occupied by Hidden Quasars

In a new study Yoshiki Matsuoka, associate professor at the Research Center for Space, told Live Science, the scientists are surprised to find that the not-so-clear quasars had occupied a large portion of the early universe. Out of 13 galaxies, 9 were found to have clear signs of active supermassive blackholes in connection with the heavy dust that hides them.

Findings Can Give Insights into the Study of Universe Evolution

Jorryt Matthee, the head of the old research, said that although there are abundant new objects found in the universe, the gap between the two known populations found by JWST is too high, and thus, there is a possibility that these belong to that missing population lying in between the known ones, providing fresh insights into how these giants formed and evolved in the early universe. The findings were reported on May 7, 2025, in the preprint database arXiv.

Future Study Scopes to Unveil the Nature of LRD

The team is planning to observe 30 more objects from the sample of the Subaru Telescope. This can reveal that the behaviour of the hidden quasars aligns with Little Red Dots. Furthermore, the gases that surround them can reveal the mysterious nature of LRD.

SpaceX Starship Flight 9 Reuses Booster, Gathers Key Data Despite Loss

SpaceX launched its ninth Starship test flight on May 27 that featured the first-ever significant reuse of Starship hardware. As planned on Flight 9, Starship’s two stages separated successfully, and the upper stage even reached space. However, both were ultimately lost before completing their objectives. Despite these setbacks, the mission yielded valuable data which inspires SpaceX’s iterative approach to innovation as it aims to create a fully reusable launch system for space missions. This test flight exhibited successful reuse of a Super Heavy booster and aimed to demonstrate improved hardware performance.

Previous test flights

According to official site of SpaceX, Starship’s two stages are one giant booster called Super Heavy and a 171-foot-tall (52 meters) upper-stage spacecraft known as Starship, or simply “Ship.” Both are powered by SpaceX’s new Raptor engine — 33 of them for Super Heavy and six for Ship.

On Flight 7 and Flight 8 the Super Heavy performed flawlessly, acing its engine burn and then returning to Starbase for a catch by the launch tower’s “chopstick” arms. But Ship had problems: It exploded less than 10 minutes after launch on both missions, raining debris down on the Turks and Caicos Islands and The Bahamas, respectively.

Advancements in flight 9

In flight 9, SpaceX reused a Super Heavy booster for the first time, swapping out just four of its 33 Raptor engines after its initial flight in January. The booster also conducted a new atmospheric entry experiment, entering at a higher angle to collect data on aerodynamic control. Meanwhile, Ship (the upper stage) was tasked with deploying eight dummy Starlink satellites.

Despite the promising advances, Flight 9 encountered several failures. Super Heavy broke apart roughly six minutes after launch during its return burn, and Ship lost control due to a fuel tank leak. The upper stage began tumbling, which prevented a planned in-space engine relight and led to a destructive reentry over the Indian Ocean. Still, SpaceX gained critical data, particularly on tile performance and active cooling systems.

7,100-Year-Old Skeleton Reveals Unknown Human Lineage in China

A new study on a 7,100-year-old skeleton from China has revealed a “ghost” lineage that only existed in theories until now. Skeleton of the early Neolithic woman, known as Xingyi_EN, unearthed at the Xingyi archaeological site in southwestern China’s Yunnan province. Her DNA links her to a deeply divergent human population that may have contributed to the ancestry of modern Tibetans. This study also reveals a distinct Central Yunnan ancestry connected to early Austroasiatic-speaking groups. This discovery makes Yunnan as a key region to understand the ancient genetic history of East and Southeast Asia. The detailed analysis of 127 human genomes from southwestern China is published in a study in the journal Science.

According to the study, radiocarbon dating indicates Xingyi_EN lived around 7,100 years ago and isotope analysis suggests she lived as a hunter-gatherer. Genetic sequencing revealed her ancestry from a deeply diverged human lineage—now named the Basal Asian Xingyi lineage. This lineage diverged from other modern human groups over 40,000 years ago and remained isolated for thousands of years without mixing with other populations.

This “ghost” lineage does not match DNA from Neanderthals or Denisovans but appears to have later contributed to the ancestry of some modern Tibetans. Xingyi_EN represents the first physical evidence of this previously unknown population.

Yunnan’s significance as a reservoir of deep human diversity

Most of the skeletons that the researchers sampled were dated between 1,400 and 7,150 years ago and came from Yunnan province, which today has the highest ethnic and linguistic diversity in all of China.

“Ancient humans that lived in this region may be key to addressing several remaining questions on the prehistoric populations of East and Southeast Asia,” the researchers wrote in the study. Those unanswered questions include the origins of people who live on the Tibetan Plateau, as previous studies have shown that Tibetans have northern East Asian ancestry.
