The *New Horizons* mission made history on Jan. 1st, 2019, when it became the first spacecraft to conduct a close flyby with Arrokoth, a Kuiper Belt Object (KBO) beyond the orbit of Pluto. The images it captured of this object, revealing a snowman-shaped profile, surprised and perplexed astronomers. Since then, astronomers have debated how such objects could form in the outer reaches of the Solar System. And now, researchers at Michigan State University (MSU) believe they have found the answer, and it's really quite simple: gravitational collapse.

Thinking about food systems in deep space likely brings to mind something like the Martian where an astronaut is scratching barely enough food to survive out of potatoes grown in Martian regolith. Or perhaps a fancy hydroponic system on an interplanetary transport ship, with artificial lighting and all the associated technological wizardry. But a new paper published in Acta Astronautica by Tor Blomqvist and Ralph Fritsche points out that growing food is only one small part of the whole cycle of providing sustenance for astronauts in space. To really get a sense of how difficult it will be, we have to look at the whole picture.

March is the time to catch the encore performance for comet E1 Wierzchos crossing the evening sky.

Searching for past or present life on Mars is the sole driving force behind every mission we send to the Red Planet, from orbiters to landers to rovers. However, there remains a concern in the scientific community of Earth-based microbes hitching a ride on Mars-bound spacecraft, also called forward contamination. The concern is potentially mistaking Earth microbes for Mars life or Earth microbes potentially influence samples of Mars life we might find. While NASA is dedicated to mitigating it as much as possible, could new methods help determine how long Earth-based microbes could survive on Mars, this alleviating concerns for forward contamination?

The Sun regularly emits streams of charged particles (solar wind) from its upper atmosphere (the corona), which flow throughout the Solar System that interacts with Earth's magnetic field. This is what powers the beautiful aurorae visible in the Northern and Southern hemispheres (Aurora Borealis and Australis. It can also play havoc with modern technological systems, including telecommunications, GPS navigation, and electrical power grids. Since 2015, NASA's Magnetosphere Multiscale (MMS) mission has been collecting data on Earth's magnetosphere.

Young stars are known for their powerful radiation and strong winds. They can shape their gaseous surroundings, both promoting and inhibiting other stars from forming, depending on the circumstances. Their strong winds also have another effect: the stars inflate gaseous bubbles around themselves.
