We use the Navier-Stokes equations every day, for applications from building rockets to designing drugs. But sometimes they break – and we don’t know why

The Japanese space-sustainability company Astroscale has unveiled a patent for what it describes as a new method for space debris removal.

Fifty-eight people have been infected—and two have died—in a New York City outbreak of Legionnaires’ disease—a severe type of pneumonia caused by a bacterium commonly associated with air-conditioning systems and cooling towers

The dashing 'Trek' veteran talks Anson's wild wig, colorful kisses, and meditating on set while directing 'the latest Star Trek: Strange New Worlds' episode.

Increasing evidence suggests chronic constipation can be a causal factor in illnesses including cardiovascular disease and cognitive impairment. So what can you do to get moving again?

Venus and Jupiter meet in the morning sky on Aug. 12. Catch their dazzling conjunction just before sunrise with the crescent moon joining later!

Second Lady Usha Vance hosted a special Summer Reading Challenge event at NASA’s Johnson Space Center in Houston on Aug. 4, 2025. She was joined by NASA astronaut Suni Williams to read a space-themed book to children in grades K-8 as part of her initiative to promote literacy.

Even today, the names of women in astronomy are not as well known as they should be.

The post Honoring the Women of Astronomy appeared first on Sky & Telescope.

Spurred by competition from China and Russia, the Trump administration is pushing for nuclear power on the moon by 2030

Electrons released when cosmic rays strike water-ice can provide energy for microbes and facilitate the formation of complex organic molecules.

From movie stars to moguls, test your knowledge of which celebrities have gone to the final frontier.

The Perseids are one of the most visually spectacular meteor showers of the year and are known for spawning impressive fireballs that light up the night sky.

Noah Hawley's daring exploration of the Alien universe makes for a great sci-fi TV show that asks big questions without neglecting the fun factor.

The world's largest optical telescope is still under construction but is raising the roof on its progress.

On the slopes of Martian mountains and craters clings what appears to be flowing honey, coated in dust and frozen in time. In reality, these features are incredibly slow-moving glaciers, and their contents were once thought to be mostly rock enveloped in some ice.

How can identifying land on exoplanets help scientists better understand whether an exoplanet could harbor life? This is what a recently submitted study hopes to address as a team of researchers investigated how identifying land on exoplanets could help dispel waterworld false positives, which occur when the data indicates an exoplanet contains deep oceans (approximately 50 Earth oceans), hence the name “waterworld”. This study has the potential to help scientists develop more efficient methods for classifying exoplanets and their compositions, specifically regarding whether they contain life as we know it, or even as we don’t know it.

If humans are planning to live off-world and colonise planets like Mars, that includes having children. But deep space and the surface of Mars aren't Earth, and there are several hazards that a gestating foetus will face, mainly microgravity and galactic cosmic rays. In a new paper, a researcher breaks down pregnancy into 10 sequential stages, evaluating what the implications of those conditions would be at each step. The author suggests that radiation would be the bigger risk.

Imagine if every time you turned on your phone, it accidentally jammed radio telescopes trying to detect alien signals. That's essentially what's happening as thousands of internet satellites flood Earth's orbit, creating electronic noise that's drowning out the whispers from black holes, distant galaxies, and the Big Bang itself. A massive new study reveals that our quest to connect every region of the planet is accidentally sabotaging our ability to answer the biggest questions in science and the problem is getting worse with every satellite launch.
