The Moons of the Solar System
New sungrazing comet C/2026 A1 MAPS could put on a fine show in April… but it will have to survive a blazing close passage near the Sun first.

Are sunrises and sunsets more spectacular in winter?
Shorter days, crisp clean air and a low winter sun all play a role in those vivid pink and golden skies.
Why are the launch windows for NASA's Artemis 2 moon mission so short?
NASA's Artemis 2 mission, which will send four astronauts on a journey around the moon, can launch on just 11 days in March and April combined. Why are there so few opportunities to fly?

The Radical Propulsion Needed to Catch the Solar Gravitational Lens
Sending a mission to the Solar Gravitational Lens (SGL) is the most effective way of actually directly imaging a potentially habitable planet, as well as its atmosphere, and even possibly some of its cities. But, the SGL is somewhere around 650-900 AU away, making it almost 4 times farther than even Voyager 1 has traveled - and that’s the farthest anything human has made it so far. It will take Voyager 1 another 130+ years to reach the SGL, so obviously traditional propulsion methods won’t work to get any reasonably sized craft there in any reasonable timeframe. A new paper by an SGL mission’s most vocal proponent, Dr. Slava Turyshev of NASA’s Jet Propulsion Laboratory, walks through the different types of propulsion methods that might eventually get us there - and it looks like we would have a lot of work to do if we plan to do it anytime soon.
Where will the annular solar eclipse be visible on Feb. 17?
The 'ring of fire' eclipse on Feb. 17, 2026, will be witnessed by more penguins than people.
Can Life Begin on a Moon Without a Sun?
Free-Floating Planets, or as they are more commonly known, Rogue Planets, wander interstellar space completely alone. Saying there might be a lot of them is a bit of an understatement. Recent estimates put the number of Rogue Planets at something equivalent to the number of stars in our galaxy. Some of them, undoubtedly, are accompanied by moons - and some of those might even be the size of Earth. A new paper, accepted for publication into the Monthly Notices of the Royal Astronomical Society, and also available in pre-print on arXiv, by David Dahlbüdding of the Ludwig Maximilian University of Munich and his co-authors, describes how some of those rogue exo-moons might even have liquid water on their surfaces.
Could the remains of a 'dead' comet still be in the solar system? Astronomers are still searching 6 years later
The fate of a comet that was predicted to pass close to Earth remains a mystery five years after its dramatic breakup in the inner solar system.

On the cusp of launching its first Vulcan rocket of the year on Thursday, United Launch Alliance leadership announced its goal for 2026 to launch between 18 and 22 times.
NASA's SPHEREx Mission Spots 3I/ATLAS's Bright Envelope
NASA's Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) was built for the ambitious purpose of performing an all-sky survey. The data it collects from more than 450 million galaxies and 100 million stars in the Milky Way over its two-year mission will help scientists explore the origins of the Universe and its evolution over time. But that doesn't mean scientists can't occasionally take a break from investigating the deepest cosmological mysteries to take a peek at an interstellar object (ISO), right?
