Astronomers have discovered powerful magnetic fields steering gas, dust, and star formation in a dramatic galaxy merger.
Friday, Jan. 30, 2026: Follow NASA's last major test of SLS before the launch of Artemis 2 and a crew of astronauts around the moon.
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.
Read an excerpt of this deep-space mystery from the prolific writer of 'Whalefall' and 'Angel Down.'
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.
NASA has been forced to delay a critical fueling test for its Artemis 2 moon rocket due to unusually cold weather forecasted to hit the Space Coast this weekend.
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.
The moon greets Jupiter two days ahead of its full moon phase on Feb. 1.
Both Windows and MacBooks have advantages for astrophotography, but the choice will depend on your power level and budget.
The dazzling Moon occults Regulus Monday night while Regulus is busy announcing February. Betelgeuse turns the Winter Hexagon into the Heavenly G.
The comet broke into pieces after making a close approach around the sun in October 2025.
"We are on Day 1. A lot more needs to be done."
A study on tectonic plates that converge on the Tibetan Plateau has shown that Earth’s fault lines are far weaker and the continents are less rigid than scientists previously thought. This finding is based on ground-monitoring satellite data.

A SpaceX Falcon 9 rocket carrying 25 Starlink satellites lifted off from California on Jan. 29, 2026. The company repeated the feat the next day with 29 satellites from Florida.
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.
