天文学家发现以 44 分钟周期发射无线电波和 X 射线的神秘天体

天文学家发现了一个以 44 分钟周期发射无线电波和 X 射线的神秘天体 ASKAP J1832-0911。这一行为与已知天体都截然不同,能周期性发射高能辐射的天体如脉冲星,其周期已知最长为百秒。44 分钟长周期是首次观察到。此类天体被称为 LPT(long-period transient),天文学家对其信号如何产生尚不清楚。研究团队认为 ASKAP J1832-0911 是一颗死亡恒星,但死亡恒星的形态未知,可能是磁星(拥有强磁场的中子星);可能是白矮星;也可能属于双星系统,其中之一有强磁场的白矮星。研究人员表示现有理论无法解释他们观测到的现象。

Telegram is riding high, adding tens of million of users this year. Now the bill is coming due.Telegram is one of the few significant social-media challengers to Facebook Inc., FB -1.90% on a trajectory toward one billion users active each month by the end of 2022, up from roughly 550 million today.

A Telegram spokesman declined to comment on the bond issue or the amount of the debt the company has due. The spokesman said Telegram’s equipment and bandwidth costs are growing because it has consistently posted more than 40% year-to-year growth in users.
