Observations show that Jupiter's icy moon Europa has a thick icy shell covering a warm ocean. The ocean is chemically-rich, and may have all the essential ingredients for life. That's why Europa is such a juicy target in the search for life, and why NASA's Europa Clipper and the ESA's JUICE are on their way to examine the moon in greater detail.

The light, rare element boron, better known as the primary component of borax, a longtime household cleaner, was almost mined to exhaustion in parts of the old American West. But boron could arguably be an unsung hero in cosmic astrobiology, although it's still not listed as one of the key elements needed for the onset of life.

When the rover now named Perseverance landed in Jezero crater in early 2021, scientists already knew they had picked an interesting place to scope out. From space, they could see what looked like a bathtub ring around the crater, indicating there could once have been water there. But there was some debate about what exactly that meant, and it’s taken almost five years to settle it. A new paper from PhD student Alex Jones at Imperial College London and his co-authors has definitively settled the debate on the source of that feature - part of it was once a beach.

Photographing a black hole has presented one of the most unique challenges in astronomy, you can't simply point a telescope at one and snap a picture. Black holes are so distant and compact that capturing their details requires multiple radio telescopes scattered across the globe to work together as one gigantic instrument. The catch? They all need to observe at precisely the same moment, with their signals perfectly aligned.

It’s 2050 and you’re living on Venus. This might come as a surprise due to the planet’s crushing surface pressures (~92 times of Earth) and searing surface temperatures (~465 degrees Celsius/870 degrees Fahrenheit), which is equivalent to ~900 meters (3,000 feet) underwater and hot enough to melt lead, respectively. But you’re not living on the surface. Instead, you’re safe and sound inside a lava tube habitat scanning data from the latest orbiter images while sipping on some habitat-made espresso.
