The InSight lander arrived on Mars's surface in November 2018 with the singular purpose of taking the planet's vital signs: its pulse, temperature, and reflexes. This largely consisted of using an advanced seismometer to measure "marsquakes," seismic waves caused by rocks cracking under heat and pressure or meteoroid impacts. By analyzing how these waves pass through the planet, scientists were able to gain valuable insight (no pun!) into the interior structure and composition of Mars. While the InSight lander ended operations in 2022, scientists are still poring over the data it collected during its four-year primary mission.

Small black holes are surprisingly messy eaters, Japanese spacecraft discovers: 'Being surprised is good'
It isn't just supermassive black holes that are messy eaters. Using a Japanese space telescope called XRISM, scientists have found that small black holes are a "hot mess," too.

One Extremophile Eats Martian Dirt, Survives In Space, And Can Create Oxygen For Colonies
Extremophiles are a favorite tool of astrobiologists. But not only are they good for understanding the kind of extreme environments that life can survive in, sometimes they are useful as actual tools, creating materials necessary for other life, like oxygen, in those extreme environments. A recent paper from Daniella Billi of the University of Rome Tor Vergata , published in pre-print form in Acta Astronautica, reviews how one particular extremophile fills the role of both useful test subject and useful tool all at once.
Ready for the next 'Oumuamua? Launching flyby missions to visiting interstellar comets is 'feasible and affordable,' study says
Conducting a flyby mission to an interstellar object visiting our solar system is "feasible and affordable," a new study finds. But orbiting such an interloper is a different story.
The Exoplanet TRAPPIST-1 e Takes Its Turn In The JWST's Spotlight
When the JWST finally began its long-awaited science operations in July 2022, there was a long list of targets awaiting its attention. Scientists compete for observing time by submitting proposals, and for every nine submitted proposals, only one gets approved. In the most recent Cycle 4 of the telescope's mission, scientists requested about 78,000 hours of observing time when only about 8700 were available.
The Messy Habits Of Small Black Holes
The best opportunity to study black holes is when they're actively accreting matter. During these times, matter gathers in an accretion disk around the black hole, where it heats up and emits electromagnetic radiation. At other times, there's simply no light.
