Details: A radio jet emitted by the black hole likely heated up a bubble of hot gas, causing it to expand and creating a shock wave that sparked star formation in other galaxies.

• Scientists have found plenty of examples of black holes that impede star formation, but this is one of the first examples of a supermassive black hole that's actually instigating it, NASA said.

• By learning more about how space weather works, scientists could craft better predictions and keep assets in space and on Earth safer.

Details: A new study published last week as part of a Parker Solar Probe-focused package in the journal Nature is shedding light on why the Sun's atmosphere gets hotter as you move farther from the star's surface.

• The probe found that strong magnetic waves — called Alfvén waves — in the solar wind near the Sun could help explain that heating.
• "They [the waves] were organized into these individual, really powerful waves that would wash over the spacecraft," one of the study's authors Justin Kasper, of the University of Michigan, told Axios.
• While these types of waves have been seen in the solar wind before, finding them organized in such a way was surprising and could help unravel the mystery of the Sun's hot atmosphere with more data.

What's next: The Parker Solar Probe is expected to make 21 more close flybys of the Sun, three of which will bring it just 3.83 million miles from the star's surface, closer than any spacecraft has been before.

• Mission managers are also gearing up for the probe to make a flyby of Venus this month, giving researchers a new look at the cloud-covered world from relatively close range.
• Scientists will use the data already gathered by the probe to add more information into models that explain how the solar wind and stellar atmosphere work.

How it works: The satellite — called TRSI Sat and developed by MyRadar — will be able to track aircraft even when they’re out over the oceans, far from the ground tracking stations that are typically used for this kind of work.

• The tiny satellite is designed to pick up pings from aircraft as they fly, relaying them back to Earth and allowing people on the ground to see where aircraft are when they're within range of the satellite.
• While this kind of satellite-based tracking has been done before, the creators of the new satellite say it cost less than $1,000 to build, and its instrumentation could be deployed on other satellites, potentially leading to global coverage.
• “It is our intention to build the tracking sensors into our future weather-based imaging satellites,” Andy Green, CEO of MyRadar, told Axios via email.

Background: The satellite was launched by a Rocket Lab Electron rocket on the company’s 10th mission last week.

• The rocket carried six other satellites to orbit, including a Japanese payload designed to create an artificial meteor shower.
• Rocket Lab also tested a guided re-entry of the first stage of its rocket in order to prove out the system’s reusability in the future.
