Another planet can orbit Proxima Centauri, the star closest to the sun seems much colder in another world than Earth. illustrating the Next Centauri: The Star Proxima Centauri (illustrated) can confirm two planets, a possibly habitable world (left) and another potential planet recently discovered (right) more massive than Earth.
The planet that orbits the closest star to the Sun may be its neighbor. It is known that Proxima Centauri, a dim red star just 4.2 light years away, is home to a potentially habitable planet, Proxima B, slightly taller than Earth (SN: 8/24/16) It is huge.
Now, they find signs of another planet, it is much larger and further from the star. If it exists, Proxima C appears at least 5.8 times larger than Earth and orbits its star once every five Earth years, the researchers reported January 15 in Science Advances.
Given its distance from Proxima Centauri, the planet is too cold to have liquid water, which is an important test for the habitat. Clues about the existence of the planet appeared in the spectroscopic data of Proxima Centauri from two telescopes in Chile, Mario Demaso, astrophysicist at the Turin Astrophysical Observatory in Italy and reports from colleagues.
The data, which have a duration of 17 years, record the movement of the star from side to side in relation to the Earth. After considering the known planet, the researchers found signs of an additional inexplicable feasible, most likely caused by stars in the gravity of another planet.
Demaso’s team emphasized that additional data is needed to confirm the existence of the planet. Given the proximity of the Earth, Proxima C may be a leading candidate for direct imaging with the next-generation large-sized telescope, scientists say. New species of squid bobble discovered.
Marine biologists have discovered a new species of the genus of fragmented squid Euprymna, known for its rich marine diversity, in the waters of the Ryuku Islands, Japan. Bobet squids (Sepiolida Order) are small cephalopods found in the shallow coastal waters of the western Indo-Pacific, the eastern Atlantic coast and the Mediterranean Sea.
The common name of these marine animals comes from their characteristic gob (mantle). Dr. of the Okinawa Institute of Science and Technology Graduate University. Daniel Rokhsar and his colleagues declared: “Our goal was to describe the buffaloes of the Ryukas and establish them within the broader systemic framework of the Indo-Pacific Brielle squid.”
The researchers examined the strange squid along the Ryuku Islands up to 20 meters deep from shallow water. “We found manure squid from three different species in these waters, and we showed them using cytochrome oxidase I sequences, transcriptome sequences and morphology.”
Two of these species were clearly related to Eupremna pardalota, a rebel squid known from northern Australia and a feast of Euprimna from Sagami Bay in mainland Japan. The third Ryukuan species was different in size and molecularly from other buffalo.
“We formally describe this new species and call it Eupremna brenneri in honor of Nobel laureate Dr. Sidney Brenner, founding president of the Okinawa Institute of Science and Technology,” the study authors said.
We propose the common name of Brenner in English and Berena-Mimica in Japanese. Euprimna brenneri, the eleventh species known in its genus, is a small squid, 8.5 to 22 mm in average length.
Adult specimens were found between corals and reefs in shallow waters near the sandy coast, at depths of less than 2 m. Their eggs were found in rocky areas near coral reefs at depths of 8-18 m. In addition to its transcription sequence, we closely analyze its morphology, the scientists said.
We saw different patterns of sprouts in their arms and tents. An article describing Euprymna brenneri was published in the journal Communications Biology.

They discover the existence of another planet in the closest star to the Sun, Proxima Centauri. An international team of scientists, with the participation of the Andalusian Astrophysics Institute (IAA-CSIC), has announced the discovery of another planet, Proxima C, which may be close to Proxima Centauri, which is closer to the Sun.
Proxima Centauri is a red dwarf just four light years from Earth. Eight times less massive than the Sun, it is evolving as an increasingly complex system. In 2016, the discovery around Proxima Centauri of the Earth-sized temperate planet, which formed the closest extrasolar planet (which they call Proxima B).
And the detection of signs of the existence of dust belts around the star in 2017 walked. Probably remnants of system formation. 24 hours – Signs of a second planet around Proxima Centauri – Listen now Audio 01.43 minutes of playback
Now, a study published in Science Advance announced that scientists have detected signs of the existence of another planet around Proxima Centauri: Proxima c. This study builds on previous work that suggests the existence of a complex planetary system around Proxima Centauri.
IIA-CSIC researcher Pedro J. At the institute we are excited about this result as it provides new information to understand the planetary system around Proxima Centauri, says Amado. As he points out, the team started by looking for the first observations for the Red Dots project.
Which resulted in the detection of the first planet Proxima B. Later, he continued to explore potential dust belts and understand the star’s atmosphere, with a point source of dust emission 1.5 times the distance from Earth to the Sun, to which he attributed the ring emission.
Second planet and now we find another planet that orbits at exactly the same distance. A coincidence? Perhaps, but we have to confirm it, says the scientist. About six times the mass of Earth: Therefore, Proxima C can have six times the minimum mass of Earth and will move around the star at 1.5 times the distance from the Sun from Earth.
The discovery has been made by an international team of researchers for data collected from Chile with UVES and HARPS spectrographs belonging to the European Southern Observatory (ESO). Observations spanning a total of 17 years reveal the presence of a 5.2-inch-spanning sign.
Which is the existence of a second planet around Proxima Centauri, which is approximately six times the mass of Earth. In the opinion of Christina Rodríguez-López, also from the IAA-CSIC and one of the scientists participating in this work.
The signal seems very reassuring, although it has not yet been ruled out that it is due to other factors, such as a cycle of magnetic stellar activity. It is an ideal planet for a combination of complementary techniques that confirm existence, and if we are successful, a modification of the models will be necessary.
Rocky planet: The signs suggest that it is a rocky planet, but it is known as the ice line, from where we find gas giant planets. A rocky planet in that area demands a new approach. The detected signal is at the limit of the instrumental capabilities.
So the researchers hope that the astrometric data taken with the Gaia satellite will play a decisive role in confirming the existence of Proxima c. It would be the only star other than the Sun that could be studied “in situ” through interstellar missions.
And the researcher has stated that this would have led to the study of other planetary systems around other stars in a “ever” way. “and it will be as follows. Able to compare these systems with solar.
