Following the collapse of the historic Arecibo Observatory in Puerto Rico, China has opened the biggest radio telescope in the world up to international scientists. In Pingtang, Guizhou province stands the Five-hundred-meter Aperture Spherical Telescope (FAST), the largest radio telescope in the world, surpassing the Arecibo Observatory, which stood as the largest in the world for 53 years before the construction of FAST was completed in 2016. Following two cable failures earlier this year, Arecibo’s radio telescope collapsed in November, shutting down the observatory for good. Now, FAST is opening its doors to astronomers from around the world.

The Chang’e-5 returner capsule carrying lunar samples is headed for a Beijing laboratory for opening, with an eagerly awaiting research team set to study the fresh Moon specimens.

Given the success of the lunar exploration mission, China space officials say a next step is to cooperate with scientists of other nations to analyze the Moon samples.

Astronomers may have found a “Planet Nine,” but in another solar system. Will we eventually find the hypothetical Planet Nine in our own Solar System?

Even with all we’ve learned about our own Solar System, especially in the last couple of decades, researchers still face many unanswered questions. One of those questions regards the so-called Planet Nine. The Planet Nine hypothesis states that there’s a massive planet in our Solar System orbiting at a great distance from the Sun.

Nobody’s ever observed the hypothesized planet; the evidence for it lies in a cluster of bodies that orbit the Sun 250 times further out than Earth does. These objects are called e-TNOs, for extreme Trans-Neptunian Objects. According to the hypothesis, Planet Nine’s gravity is responsible for the unusual clustered orbits of these e-TNOs.

Now astronomers have found a distant solar system with its own Planet Nine, and that discovery is breathing new life into the hypothesis.

Similar findings may tell scientists about magnetic fields around exoplanets.

Scientists may have detected radio emissions from a planet orbiting a star beyond our sun for the first time.

The astronomers behind the new research used a radio telescope in the Netherlands to study three different stars known to host exoplanets. The researchers compared what they saw to observations of Jupiter, diluted as if being seen from a star system dozens of light-years away. And one star system stood out: Tau Boötes, which contains at least one exoplanet. If the detection holds up, it could open the door to better understanding the magnetic fields of exoplanets and therefore the exoplanets themselves, the researchers hope.

Despite lack of large marsquakes, InSight team fixes size of crust, mantle, and core.

Using the Parkes radio telescope, Chinese astronomers have investigated an isolated pulsar known as PSR J1047−6709 and detected dozens of giant pulses during the bright state of this source. The finding is reported in a paper published December 10 on the arXiv pre-print repository.

Pulsars are highly magnetized, rotating neutron stars emitting a beam of electromagnetic radiation. They are usually detected in the form of short bursts of radio emission, however, some of them are also observed using optical, X-ray and gamma-ray telescopes. To date, most pulsars have been discovered using the Parkes Observatory in Australia.

Some pulsars showcase the so-called giant pulses (GPs)—short-duration, burst-like radio emissions from a pulsar, with energies exceeding the average pulse energy by 10 times or even much more. So far, such activity has only been detected in 16 pulsars.
