The Moon's getting to be a popular place. Firefly's Blue Ghost touched down on March 2nd in Mare Crisium. It's the first privately built lander to land safely and begin its mission. The little spacecraft set down safely in an upright, stable position and sent back an "I'm here" signal right away.

The dividing line between gas giant planets and failed stars is blurry at best. The isolated planetary-mass object SIMP J013656.5+093347.3 could be either one. The distinction is largely semantic. However we choose to label and define it, the object displays a surprisingly complex atmosphere for an isolated object without any stellar energy input.

We can't take our telescopic eyes off of supernova explosions. There's something compelling about natural objects so massive that they're doomed to terminate themselves in powerful explosions that outshine their host galaxies. Their patterns of shocked and lit-up gas are pleasing to the eye and ignite our curiosity. What exactly is going on to produce these gorgeous forms?

In an effort to conserve Voyager 2's dwindling energy and extend the spacecraft's mission, NASA has shut down another of its instruments. They did it with the Plasma Spectrometer in October 2024, and it won't be the last. In March, Voyager 2's Low-Energy Charged Particle instrument will be powered down.
