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.

NASA’s Perseverance rover is exploring the Martian rim of Jezero Crater, a crater filled with rocky outcrops. The mission has cored five rocks, performed up-close analysis of seven rocks, and analysed another 83 from afar using a laser. The diversity of rocks found has exceeded expectations, with tons of fragmented once-molten rocks and formerly underground boulders juxtaposed with well-preserved layered rocks. The first crater-rim rock sample, “Silver Mountain,” was collected from “Shallow Bay,” likely formed 3.9 billion years ago during Mars’ earliest geological period.

Perseverance Rover Unearths Clues to Mars’ Watery Past in Jezero Crater Rocks

Deep in the Martian crust, the crew came upon an outcrop featuring igneous minerals solidified from magma. Working with ESA, NASA’s Mars Sample Return Program gathers sealed samples from Mars for detailed investigation.

NASA’s Perseverance rover is collecting data on Mars as it examines rock formations that may contain evidence of the planet’s geological history. The rover is currently traversing terrain near the rim of Jezero Crater, a basin north of the Martian equator believed to have once held a lake. After reaching the crater’s western edge in December, it has been studying the stratified terrain of Witch Hazel Hill, which may offer information about past environmental conditions on Mars.

In the past few months, the car-sized Perseverance has collected samples of five rocks, performed detailed analysis on seven others, and zapped an additional 83 with its laser for remote study.

Perseverance Finds Ancient Rocks at Jezero Crater Rim, Boosting Search for Life on Mars

The western rim of Jezero Crater contains fragmented igneous rocks that may have originated from deep below the Martian surface, likely ejected by meteor impacts. These may include the impact that formed the crater itself. Perseverance’s first sample from the rim, named Silver Mountain, is estimated to be at least 3.9 billion years old, potentially from the Noachian epoch.

Nearby, the rover identified a boulder rich in serpentine minerals. Researchers note that such material could produce hydrogen under certain conditions, which is considered a possible energy source for microbial life. The mission team is using recent data to determine the next sampling site along the crater rim.

Australian researchers have reportedly discovered several previously undocumented species on the Antarctic seafloor, including palm-sized spider-like creatures and an eyeless, gelatinous animal known as a “sea pig.” The spider-like species are said to be more closely related to crabs than to spiders, have long legs and compact bodies. Researchers noted that the appearance of these animals can vary when removed from their natural environment. For instance, the sea pig is reportedly more uniform and structured while moving along the seabed than when brought to the surface.

Rare Sea Pigs and Giant Sea Spiders Found in Antarctica

According to an ABC News report, scientists also encountered marine stars roughly the size of a dinner plate and sea spiders with leg spans reaching up to 20 inches. The sea spiders, characterised by long, thin legs and small bodies, were collected using a specially designed “wet well” — a seawater-filled tank on board the research vessel that helps preserve fragile specimens. In one of the ship’s aquariums, a sea butterfly laid eggs, giving researchers a rare opportunity to observe its reproductive process. The team continues to study the behaviour and development of these species in controlled conditions.

Scientists aboard the Australian icebreaker RSV Nuyina have collected a range of marine species during a 60-day expedition to the Denman Glacier in East Antarctica. The team is surveying the ocean floor at depths between 3,300 and 19,500 feet to study organisms adapted to extreme conditions.
Among the discoveries are sea stars the size of dinner plates, sea spiders with leg spans up to 20 inches, and sea pigs — gelatinous animals related to sea cucumbers that feed on organic debris known as “marine snow.” A sea butterfly, a small marine mollusc resembling a flying snail, laid eggs in an onboard aquarium, allowing researchers to observe its early development.

Sea Spiders and Flying Snails Found in Antarctic Depths

Sea spiders, which are arthropods distantly related to crabs, inhabit a wide range of marine environments, including deep-sea habitats up to 13,000 feet below the surface. Over 1,300 species are known, some with internal organs that extend into their legs.

Fragile specimens were collected using a “wet well” tank — a seawater system on the vessel designed to preserve deep-sea organisms during transport and observation.
