Strange behavior caught by two radio observatories may send theorists back to the drawing board.

Fourteen years ago, the first fast radio burst (FRB) was discovered. By now, many hundreds of these energetic, millisecond-duration bursts from deep space have been detected (most of them by the CHIME radio observatory in British Columbia, Canada), but astronomers still struggle to explain their enigmatic properties. A new publication in this week’s Nature “adds a new piece to the puzzle,” says Victoria Kaspi (McGill University, Canada). “In this field of research, surprising twists are almost as common as new results.”

Most astronomers agree that FRBs are probably explosions on the surfaces of highly magnetized neutron stars (so-called magnetars). But it’s unclear why most FRBs appear to be one-off events, while others flare repeatedly. In some cases, these repeating bursts show signs of periodicity, and scientists had come up with an attractive model to explain this behavior, involving stellar winds in binary systems.

Collins Aerospace, a subsidiary of military and aerospace contractor Raytheon Technologies, is working on environmental control and life support technologies for a “privately owned and operated low Earth orbit outpost,” according to SpaceNews.

There’s plenty of money being poured into developing a commercial presence in space right now. The small firm was awarded a $2.6 million contract by a mysterious unnamed customer — a sign, in spite of its opacity, that the race to commercial orbit is heating up.

Planet Nine, according to scientists, has an orbit that lies more than 300 AU from the sun and is tilted.

During an upcoming NASA mission, currently scheduled for an October lift-off, a spacecraft called Lucy will be the first to visit a fleet of primordial bodies trailing behind Jupiter. It will launch on the Atlas V 401 rocket.

The Lucy mission will be the first to explore the Trojan asteroids, a large group of asteroids that share Jupiter’s orbit around the Sun.

On Friday, NASA released a time-lapse taken by the Perseverance rover of a Martian moon named Deimos.

The solar sailing CubeSat is one of several secondary payloads hitching a ride on Artemis I, the first integrated flight of the agency’s SLS and the Orion spacecraft.
