These are the top space stories this week from Space.com.
It's been a great, enormous storm for more than a 100 years. But will Jupiter's Great Red Spot last much longer?
Another long-lived NASA mission has come to an end, this one after more than seven years of dancing through the perilous belts of radiation around Earth.
Giant alien worlds with searing, close orbits to their host stars can inflate like balloons. Now astronomers have discovered one so puffy that it is one of the least dense planets ever discovered.
The Milky Way glistens above four antennas of the Atacama Large Millimeter/submillimeter Array (ALMA), a telescope array in northern Chile.
Our home galaxy stole several dwarf galaxies that used to belong to the Large Magellanic Cloud (LMC), a galaxy near the Milky Way.
By analyzing the disintegrated remains of distant worlds consumed by their stars, a new study found that at least some rocky exoplanets may have interiors similar to those of Earth and Mars.
A nonprofit called The Earth Archive wants to make a 3D map of the entire planet, before the climate crisis changes Earth's face forever.
Here's the reality: We're messing up the Earth and any far-out ideas of colonizing another orb when we're done with our own are wishful thinking.
Big, schmancy compounds keep popping up all over the solar system, and new research may help clear up confusion about how they form in so many places.
New photos give us the best-ever look at NASA's InSight lander on the surface of Mars and show the circuitous route the Curiosity rover is taking up a big Red Planet mountain.
NASA's venerable Hubble Space Telescope turned its eyes to interstellar visitor Comet 2I/Borisov and caught a surprise: The interloper looks a lot like comets from our own solar system.
NASA is already pulling together plans for what could become its first long-lived robotic rover on the moon's surface, designed to sniff out water and targeting a landing date of 2022.
The 1995 discovery showed that the sun isn't the only star to host a family of planets — something we had long figured but never demonstrated — and also that the universe is really, really weird.
Some ice deposits on the moon are younger than expected, researchers say, and it appears these deposits came from multiple sources at different times in our solar system's history.
