Communication with Other Intelligent Life
Aboard the Voyager probe lies two golden phonographic records with information meant for alien life. Today’s bite explores what we put on those records and why.
FRB 121102 CHIMEs in Again
Fast radio bursts, or FRBs, are a newer and somewhat mysterious phenomenon in radio astronomy. This paper details how the authors used a new instrument called CHIME/FRB to observe and put new constraints on FRB 121102, one of the few FRBs known to repeatedly send signals.
The Mysterious Pulsars That Switch On and Off
Pulsars emit radio radiation, but sometimes they just randomly switch off. Why is that?
A Second Mysterious Radio Outburst from Magnetar XTE J1810-197
Why is one magnetar giving off bursts of energetic radio waves? Is it related to giant pulses? FRBs? Both?
Moonetesimals likely form relatively quickly
The absence of dusty circumplanetary disks around young giant planets suggests moonetesimals grow relatively quickly.
Radio Pulsars: How Slow Do They Go?
The discovery of the slowest rotating radio pulsar, PSR J0250+5854, has scientists wondering – how slow do radio pulsars spin?
