"According to our knowledge, neutron stars rotating so slowly should stop emitting radio pulses. But ASKAP J1839-0756 breaks these rules," said study authors Manisha Caleb, Yu Wing Joshua Lee.
ASKAP J1839-0756 has another unique feature: it emits radio pulses from two opposite magnetic poles. This phenomenon is extremely rare even for fast pulsars, and for such slow objects it is observed for the first time.

Scientists have revealed what the Universe was like before the Big Bang

The object was discovered using the ASKAP radio telescope in Australia . Its unusual activity was noticed during routine observations: the object emitted radio bursts, the brightness of which decreased by 95% in 15 minutes. Later, long-term observations confirmed that the bursts were repeated at intervals of 6.5 hours. For further studies, the team used the ATCA telescope in Australia and MeerKAT in South Africa.

One hypothesis is that ASKAP J1839-0756 is a magnetar, a special type of neutron star with a powerful magnetic field. However, magnetars usually rotate faster, and their periods are measured in seconds. Another version suggests that it could be a white dwarf, the remnant of a less massive star. However, no single white dwarf has ever vnpay database detected as a source of radio bursts.

This object changes our views on what is possible in the nature of neutron stars," the scientists added. "It opens up new horizons for research and forces us to reconsider established theories."

SpaceX has started offering its customers in Australia a 5GB Starlink "backup connection" plan for AUD$15 (about 950 rubles), PCMag reports.

Despite the small amount of data, SpaceX says the solution is useful in the event of a main internet outage or emergency. Additional data can be purchased for AUD$3 (about €2.90) per GB, which can be used “on the move, overseas, and in coastal waters.”

This offer is likely aimed at customers who have suspended their Starlink subscription or are planning to stop using the operator's services. In this case, subscribers can reactivate Starlink service and switch to a backup tariff.
